HEY, AND WELCOME TO OUR
UNREAL ENGINE LIVE STREAM.00:03:06
I'M YOUR HOST AMANDA BOTT.
WE HAVE SAM DEITER,00:03:09
WE ALSO HAVE PAULO SOUZA,
CALLING IN FROM BRAZIL,00:03:17
NEWLY TITLED TECHNICAL
ACCOUNT MANAGER,00:03:19
AND ON HIS FIRST EVER

OUR COMMUNITY MANAGER
VICTOR BRODIN.00:03:26
SO SUPER PUMPED TO
HAVE VICTOR JOIN US.00:03:29
>>VICTOR: PSYCHED TO BE
HERE.00:03:30
>>AMANDA: SINCE IT IS YOUR FIRST
LIVE STREAM,00:03:32
DO YOU WANT TO GIVE A LITTLE BIT
OF BACKGROUND ON WHO YOU ARE?00:03:35
>>VICTOR: SURE. I HAVE
BEEN WORKING WITH THE ENGINE00:03:37
FOR ALMOST FIVE YEARS NOW,00:03:39
I STARTED MAKING VR PROJECTS
WHEN DK1 WAS FIRST RELEASED.00:03:44
THAT TURNED INTO A TURMOIL
OF MAKING A LOT OF GAMES,00:03:48
VR PROJECTS, I WAS TEACHING
FOR A LITTLE BIT,00:03:52
AND THEN DID
A COUPLE CONTRACTS,00:03:54
DID A START-UP,
RELEASED A COUPLE GAMES,00:03:57
MY LAST JOB WAS OVER AT OCULUS.00:03:59
SO WE STARTED TO DO
SOME VR STUFF IN THE FUTURE.00:04:03
AND, YEAH, I THINK --
A QUICK OVERVIEW OF MY HISTORY,00:04:06
IF YOU HAVE QUESTIONS, YOU
CAN FIND ME ON DISCORD.00:04:08
I'M THERE MOST OF THE TIME.00:04:10
>>AMANDA: TRICKING
PEOPLE UP ON YOUR NAME.00:04:12
>>VICTOR: RIGHT. YEA, IT'S
NOT ACTUALLY LERP.00:04:17
>>AMANDA YOU HAVE DISAPPOINTED
MANY INTERNAL PEOPLE HERE.00:04:21
>>VICTOR: YEAH, AND THEY TOLD ME SO.
>>AMANDA: HAHA.00:04:24
SO THIS WEEK,
WE'RE DIVING INTO --00:04:27
>>SAM: ACTION RPG.00:04:29
SO WE DID A STREAM IN THE PAST
ON ACTION RPG, AND THAT WAS --00:04:34
LET ME TAKE A STEP BACK.00:04:35
SO THE WHOLE PURPOSE OF ACTION
RPG WAS TO GIVE PEOPLE00:04:39
WHO USE UE4 A BREAK DOWN ABOUT
HOW THE ABILITY SYSTEM WORKS,00:04:43
THAT IS DEMONSTRATED
IN ACTION RPG00:04:45
IS USED IN FORTNITE
AND PARAGON.00:04:50
THE FIRST STREAM
THAT WE HAD WAS BASICALLY00:04:52
TO KIND OF GIVE YOU AN IDEA
OF HOW THE ABILITY SYSTEM WORKS.00:04:57
THIS STREAM IS TO BREAK DOWN
A LITTLE BIT MORE00:04:59
ABOUT HOW THINGS INSIDE
OF ACTION RPG WORK,00:05:02
AND GIVE YOU SOME MORE IDEAS00:05:05
ABOUT WHERE WE ARE GOING
WITH THIS PROJECT,00:05:07
AND WHAT WE WOULD LIKE
TO ACHIEVE WITH IT.00:05:09
PAULO WAS ONE OF
THE OTHER PEOPLE00:05:12
THAT WAS HIGHLY INVOLVED IN
THE DEVELOPMENT OF ACTION RPG.00:05:15
SO THIS GAME WAS
BASICALLY-BUILT --00:05:21
WE HAVE THESE THINGS
CALLED EPIC FRIDAYS,00:05:23
YOU GET A FRIDAY
TO BUILD WHATEVER YOU WANT.00:05:26
SO IT WAS BUILT
BY THE TEAM IN KOREA,00:05:29
AND THEN PRIORITIES SHIFTED
AND THEY PUT IT OFF.00:05:33
PAULO DUSTED IT OFF
BECAUSE IT WAS,00:05:36
AND CORRECT ME
IF I'M WRONG HERE,00:05:37
BUT THERE WERE FOUR EXAMPLES
IN ONE GITHUB RESOURCE00:05:41
THAT YOU NEED TO COMPILE
TOGETHER INTO A SINGLE PROJECT00:05:43
TO SHOW MOST
OF THE FUNCTIONALITY00:05:45
THAT WE DEMONSTRATED
IN ACTION RPG.00:05:47
>>PAULO: YES,
SOMETHING LIKE THAT.00:05:49
>>SAM: SO THIS PROJECT
WAS TO HELP HIM00:05:52
JUST HAVE ONE PROJECT
THAT YOU CAN POINT PEOPLE TO,00:05:55
AND ALSO SHOW HOW UNREAL
CAN DO ONE TO MANY.00:05:58
THIS PROJECT WORKS ON ANDROID,
IOS, HTML FIVE,00:06:03
WINDOWS, MAC, LINUX,
A FEW UNANNOUNCED PLATFORMS,00:06:07
AND SHOULD BE ON CONSOLES,00:06:09
WE HAVE NOT PUT IT
ON A CONSOLE YET -00:06:12
BUT IT SHOULD RUN ON THERE
AND WE HAVE MADE IMPROVEMENTS00:06:16
AND UPDATES TO IT.00:06:17
ONE THING I WANT TO SHOW YOU
BEFORE WE JUMP00:06:21
INTO A LOT OF STUFF IS --
LET ME EXPAND THIS.00:06:25
THIS IS THE ACTION
RPG DOC PAGE IT.00:06:27
IT ORIGINALLY HAD THESE
THREE SECTIONS UP HERE,00:06:31
SETTING UP THE ABILITY SYSTEM,00:06:34
BALANCING BLUEPRINTS
AND C++, AND THEN00:06:36
BREAKING DOWN HOW
THE ABILITIES WORK.00:06:39
OVER THE LAST COUPLE OF WEEKS,
I HAVE CARVED OUT SOME TIME00:06:43
TO ADD A BUNCH OF DOCUMENTS HERE00:06:46
THAT GO ON THE CONTENT CREATION
SIDE OF THINGS.00:06:48
WE HAVE ADDING A RANDOM AMOUNT
OF SOULS PER KILL,00:06:52
ADDING A PICK UP,
MIGRATING CONTENT,00:06:54
ADDING A NEW WEAPON,
AND ADDING A NEW POTION.00:06:57
AND EACH ONE OF THESE
ARE MEANT TO SHOW YOU00:06:59
A DIFFERENT ASPECT OF THE GAME.00:07:01
THEY ARE SET UP
IN A WAY THAT BASICALLY --00:07:04
IT GOES SUPER EASY
FOR ADDING A POTION,00:07:07
ADDING A WEAPON
IS SLIGHTLY MORE COMPLEX --00:07:11
PICK UP, JUST A LITTLE BIT
MORE COMPLEX THAN THE OTHER TWO,00:07:14
I SAID THAT BACKWARDS,
ADDING A RANDOM SOUL,00:07:17
AND ADDING A PICK UP
IS THE MOST COMPLEX.00:07:22
MIGRATING CONTENT IS
HOW I WAS BRINGING00:07:25
CONTENT OVER FROM THE
INFINITY BLADE WEAPONS PACKS,00:07:28
BECAUSE I HAD TO END UP
REPEATING THOSE STEPS,00:07:32
SO I JUST MADE
ANOTHER DOCUMENT FOR IT.00:07:34
WITH THAT OUT OF THE WAY,00:07:37
LET'S TALK ABOUT WHAT
OUR CURRENT IMPROVEMENTS ARE.00:07:40
I'M GOING TO MOVE
THIS PAGE OVER.00:07:44
AND ONE OF THE THINGS
THAT PAULO DID --00:07:47
>>PAULO: YAY.
>> [ LAUGHTER ].00:07:49
>>SAM: -- WE'RE GOING TO
CLICK ON THIS SCREEN RIGHT HERE,00:07:52
AND LET'S SKIP THE INTRO.
SO FIRST OFF,00:07:54
YOU NOTICE THAT I HAVE DIFFERENT
CONTROLS HERE FOR MY PC.00:08:00
THE COOL THING ABOUT THIS IS,
WHEN I GO ON MOBILE,00:08:02
I WILL HAVE MOBILE CONTROLS.00:08:04
MY UI DOWN HERE
IS SLIGHTLY DIFFERENT,00:08:07
WHEN I'M ON PC,
I HAVE THE PC CONTROLS,00:08:09
IT IS PROBABLY A LITTLE HARD
TO MAKE OUT,00:08:11
BUT THERE IS A LEFT CLICK,
A RIGHT CLICK,00:08:14
AND SPACE BAR,
MAKES ME ROLL.00:08:17
TAB OPENS UP THE UI.00:08:20
ONE OF THE COOLEST THINGS
I THINK HE DID WAS THIS.00:08:23
I WILL GRAB THE EDGE
OF THE WINDOW,00:08:26
I WILL MAKE THE UI
REALLY BIG OR SMALL,00:08:29
AND NOTICE THE UI STAYS EXACTLY
WHERE IT SHOULD BE,00:08:33
UNLESS I PUT IN
A CRAZY RESOLUTION.00:08:36
THE REASON IT IS SO COOL
IS THERE IS NO NEED FOR YOU00:08:40
TO MESS WITH THE COMPLICATED UI00:08:42
SCALING CURVES
OR ANYTHING LIKE THAT.00:08:44
THE UI WILL STAY IN PLACE IN
RELATION TO WHATEVER RESOLUTION00:08:48
YOU ARE VIEWING THE GAME ON.00:08:50
THIS IS AWESOME BECAUSE, IF YOU
HAD TO MESS WITH UI CURVES,00:08:55
YOU HAD TO MAKE A BUNCH
OF SPECIAL ENTRIES00:08:58
FOR WHATEVER WEIRD
RESOLUTION YOU MIGHT HAVE00:09:01
NOT NECESSARILY
BE SCALING THE UI TO CORRECTLY,00:09:05
OR YOU JUST MISSED
AN UI ELEMENT AND NOW --00:09:08
YOU MISSED A SETTING,
YOU MISSED A RESOLUTION,00:09:11
AND NOW YOU HAVE YOUR UIS
ON TOP OF ONE ANOTHER.00:09:16
WE ADDED A COUPLE NEW WEAPONS
AND POTIONS,00:09:19
I HAVE A PICK UP HERE,
A POTION, AND A SWORD,00:09:26
THESE ARE THE RESULTS OF THE
DOCUMENTS I SHOWED YOU EARLIER.00:09:29
I ALSO WENT IN AND APPLIED
PROXY GEO AND HLOD --00:09:34
LET ME SEE
IF I CAN FIND THE OTHER PIECES.00:09:36
YOU CAN SEE IT IS NOT THERE, IT
IS MADE UP OF INDIVIDUAL MESHES.00:09:42
AS I GO BACK, IT WILL --
OOPS, IT WILL FADE OUT.00:09:46
A LITTLE BIT TOO FAR BACK THERE.00:09:48
YOU CAN SEE THAT IT MADE IT
ONE PIECE.00:09:50
THIS IS GOOD BECAUSE ON MOBILE,00:09:51
YOU WANT AS FEW DRAW CALLS
AS POSSIBLE.00:09:54
SO WHAT THIS IS DOING,
IT IS NON-DESTRUCTIVELY00:09:57
REPLACING THOSE PIECES
IN THE BACKGROUND00:09:59
WITH ONE MESH
AND ONE MATERIAL,00:10:01
MAKING THIS PIECE, WHICH IS
PROBABLY FIVE OR SIX INDIVIDUAL00:10:05
STATIC MESHES INTO,
AGAIN,00:10:07
ONE MESH, ONE MATERIAL,
WHICH IS ONE DRAW CALL,00:10:10
WHICH IS WHAT
YOU WANT ON MOBILE.00:10:12
SOME PLANNED IMPROVEMENTS
THAT WE HAVE.00:10:17
WE WILL IMPLEMENT PSO CACHING,00:10:20
THAT IS THE NEW FORM
OF SHADER CACHING.00:10:24
THERE ARE DOCUMENTS
THAT ARE WRITTEN ABOUT IT,00:10:26
WE HAVE PSO DATA GENERATED,00:10:29
JUST HAVEN'T ACTUALLY
WRITTEN THE CODE00:10:33
THAT COMPILES IT
DURING THE INTRO,00:10:37
I CANNOT THINK OF THE NAME
OF THE WORD, LOADING IMAGE --00:10:42
>>PAULO: LOADING?00:10:43
>>SAM: I DON'T KNOW. IT JUST
TOTALLY FELL OUT OF MY HEAD.00:10:46
>>PAULO: LOADING SCREEN.00:10:47
>>SAM: LOADING
SCREEN, THERE WE GO.00:10:49
WE'RE GOING TO LOOK INTO
DOING LOCAL NOTIFICATIONS00:10:53
FOR AN IN-GAME EVENT,
POSSIBLY ADDING SOCIAL SUPPORT,00:10:58
AND SOME PROCEDURAL GENERATION
FOR THE LEVELS,00:11:01
AS WELL AS DIFFERENT
ENEMY TYPES AND BEHAVIORS.00:11:04
AND FINALLY, SO --
AN IMPROVEMENT00:11:07
THAT IS NOT GOING TO HAPPEN
IS MULTIPLAYER.00:11:09
AS IT CURRENTLY STANDS,00:11:10
ACTION RPG WILL
NEVER HAVE MULTIPLAYER.00:11:14
I'M NOT SAYING THAT
THERE MIGHT BE SOME RESOURCES00:11:17
THAT ALLOW ME TO DO THIS,00:11:19
THE REASON WE DON'T HAVE
ANY PLANS FOR IT00:11:21
IS WE MADE A DECISION
AT THE BEGINNING OF THIS GAME00:11:23
DUE TO TIME CONSTRAINTS TO MAKE
SURE WE GOT IT OUT ON TIME,00:11:27
WE DIDN'T BUILD IT
WITH MULTIPLAYER IN MIND.00:11:31
IF WE DID, IT WOULD REQUIRE
A MASSIVE REWRITE00:11:33
OF HOW WE ARE IMPLEMENTING00:11:35
THE ABILITY SYSTEM TO DEAL WITH00:11:37
REPLICATION AND
DAMAGE CALCULATION.00:11:39
WE DIDN'T HAVE THE TIME
WHEN WE WERE DOING THIS00:11:44
TO ACTUALLY IMPLEMENT THAT.00:11:46
THAT BEING SAID, IF YOU ARE
LOOKING FOR AN EXAMPLE00:11:48
OF HOW TO DO MULTIPLAYER,00:11:50
THE BEST EXAMPLE
IS SHOOTER GAME.00:11:52
THAT WILL SHOW YOU THE EPIC WAY00:11:55
TO SET UP
A MULTIPLAYER PROJECT,00:11:57
SO THAT IS A SUPER VALID
RESOURCE FOR THAT.00:12:01
PAULO,
DO YOU HAVE ANYTHING00:12:02
THAT YOU WOULD LIKE
TO ADD FOR THIS?00:12:05
>>PAULO: SURE. ONE THING THAT IS
COMING UP SOON, AT SOME POINT,00:12:10
IS SUPPORT FOR MULTIPLE
TRANSLATIONS --00:12:14
WE ARE WORKING ON
ADDING NEW REGIONS,00:12:19
AND NEW LOCALS, TO ACTION RPG.00:12:22
WE WILL FINALLY HAVE
A SAMPLE PROJECT00:12:25
THAT IMPLEMENTS THE LOCALIZATION
SYSTEM IN UNREAL00:12:31
SO OTHER DEVELOPERS CAN LOOK AT
AND USE IT AS A REFERENCE.00:12:35
WE ARE NOT SURE THE LANGUAGES
AT THIS POINT00:12:40
BUT, I MEAN,
SINCE IT IS USED AS AN EXAMPLE,00:12:43
JUST A BUNCH OF
THEM, LIKE 3 OR 4,00:12:46
JUST SO DEVELOPERS CAN LOOK
AT A PROPER EXAMPLE FOR THAT.00:12:51
>>SAM: SO PROBABLY ADD ENGLISH,
BAD ENGLISH MAYBE --00:12:54
>> [ LAUGHTER ].00:12:55
>>SAM: MAYBE COCKNEY --00:12:57
>>PAULO: WELL, I CAN DO
PORTUGUESE.00:13:02
>>SAM: SO
LET'S GO AHEAD AND...00:13:05
LET'S TAKE A
LOOK AT THE POTION.00:13:08
SO ONE OF THE THINGS I WANTED
TO TALK ABOUT THE POTION IS,00:13:12
BASICALLY THIS IS
ALL MADE USING JUST00:13:15
SIMPLE DATA ASSETS
INSIDE OF UNREAL.00:13:19
WE CAN SEE THAT THIS POTION
RIGHT HERE,00:13:21
THIS IS JUST A DATA ASSET,00:13:22
WHICH IS LINKED
OFF OF RPG POTION ITEM.00:13:27
WHAT THIS DOES,
THIS IS WHAT CONTROLS00:13:29
WHAT YOU SEE
INSIDE OF THE STORE,00:13:31
AND ALSO SETS THE PRICE
AND THE AMOUNT THAT YOU HAVE.00:13:34
SO LET ME GO BACK AND, UH,
I MEAN -- HOLD ON A SECOND HERE.00:13:38
PULL THIS DOWN
SO I CAN GET THIS GUY00:13:40
AND RUN IT
IN the SELECTED VIEWPORT.00:13:42
SO WHEN I TAB HERE
OVER TO THE POTIONS,00:13:46
YOU CAN SEE THE DEATH DOOR
POTION HERE,00:13:48
ALL OF THE INFORMATION
THAT IS CONTAINED HERE,00:13:51
THE PRICE, A LITTLE DESCRIPTION,
ESCAPE OUT OF THAT --00:13:54
SO I CAN GET BACK TO THIS, NO.
THERE WE GO --00:13:58
IS CONTAINED WITHIN
THIS DATA ASSET RIGHT HERE.00:14:02
LET ME CLOSE THIS
WINDOW AND GO TO THESE.00:14:05
SO WE HAVE GA AND GE PREFIXES.00:14:08
GA
IS THE GAMEPLAY ABILITY.00:14:10
I'M GOING TO OPEN IT UP,
AND WE WILL PULL IT OVER HERE.00:14:13
SO WHAT THIS IS DOING IS --
THIS IS ALL OF THE --00:14:18
AND I THINK I ACCIDENTALLY
LABELLED THESE BACKWARDS, HAHA.00:14:21
HANG ON ONE SECOND HERE.
I JUST REALIZED MY MISTAKE.00:14:26
YES, I DID. I TOTALLY
LABELLED THESE BACKWARDS.00:14:29
OH, WELL.00:14:30
SO, UM, LET ME GO BACK HERE
AND CLOSE THIS00:14:36
AND OPEN THIS ASSET BACK UP.
SO WHAT THIS IS DOING RIGHT HERE00:14:39
IS THIS IS ACTUALLY EDITING
THE --00:14:45
THIS IS WHAT I WAS LOOKING FOR.
I WAS LIKE, WHERE DID IT GO?00:14:47
I WILL KEEP GOING DOWN HERE,
ALL RIGHT.00:14:56
I'M SORRY.00:15:01
THIS IS WHAT IS CONTROLLING
THE ACTUAL VISUALS00:15:04
OF THE WHAT'S GOING ON
WITH THIS EFFECT.00:15:06
SO IF I COME HERE,
AND THIS IS THE --00:15:09
THIS IS THE TARGETING,00:15:10
SO RIGHT HERE IS THE EFFECTS
CLASS TO PLAY.00:15:13
BUT THIS IS THE MAIN THING00:15:14
YOU WANT
WITH THIS PARTICULAR ONE,00:15:16
AND IT'S THE MONTAGE HERE,
YEAH, I FORGOT ABOUT THAT.00:15:21
THE MONTAGE BASICALLY,
I'M USING THE SAME MONTAGE00:15:25
THAT I USED FOR THE HEALTH
AND THE MANA POTION,00:15:28
AND I SLOTTED THIS IN, I DIDN'T
HAVE TO CHANGE ANYTHING,00:15:32
OR MAKE A NEW MONTAGE
AND PUT ALL OF THIS IN THERE,00:15:35
EVERYTHING THAT WAS DONE
FROM THIS MONTAGE00:15:38
IS WHAT WAS ORIGINALLY IN
THE HEALTH AND THE MANA POTION.00:15:44
THAT IS HERE, AND THIS CONTROLS
BASICALLY THE VISUALS.00:15:48
I WILL GO BACK
TO THE POTION HERE,00:15:51
AND THIS IS WHAT CONTROLS00:15:53
THE VALUES
THAT ARE APPLIED TO THIS.00:15:55
AND THOSE ARE RIGHT HERE,
THE MODIFIER.00:15:59
THE FIRST MODIFIER IS THE
RPGATTRIBUTESETHEALTH,00:16:03
AND THEN WE HAVE
THE RPGATTRIBUTESETMANA.00:16:08
AND WHAT I DID
WHEN I CREATED THIS,00:16:10
I JUST DUPLICATED
THE HEALTH ONE.00:16:12
SO I CAME UP HERE,
AND I LITERALLY RIGHT-CLICKED00:16:14
AND I DUPLICATED IT.
ONCE I OPENED IT UP,00:16:18
I OPENED UP THE ARRAY HERE,
I SET IT TO MANA,00:16:22
AND IN THE MAGNITUDE
THAT CONTROLS THE AMOUNT,00:16:28
I SET IT TO 2, MADE SURE
IT USES THE ATTACK DAMAGE,00:16:33
EVEN THOUGH
IT SAYS ATTACK DAMAGE,00:16:35
THESE ARE THE NUMBERS
THAT WE CAN USE00:16:37
FOR BASICALLY WHATEVER --
AND THAT IS ALL I HAD TO DO.00:16:42
I JUST HAD TO SET THIS TO 2
SO IT MATCHED00:16:44
WHAT I WAS SETTING UP HERE,
WHICH IS ONE.00:16:46
THIS LOOKS LIKE I DIDN'T
UPDATE THE BUILD CORRECTLY,00:16:50
BUT BY INCREASING THESE NUMBERS
RIGHT HERE,00:16:54
WE ARE GOING TO INCREASE00:16:56
THE EFFECT
THAT IS APPLIED TO THE PLAYER,00:16:58
SO THIS IS SUPPOSED TO GIVE US
BACK HALF OF OUR HEALTH00:17:01
AND HALF OF OUR MANA; THAT IS
WHY I INCREASED THESE TO 2 --00:17:04
TO GIVE US A LITTLE BIT MORE
THAN WHAT WE CURRENTLY HAVE.00:17:08
THAT'S PRETTY MUCH IT,
THAT'S ALL I HAD TO DO.00:17:11
AND ONE THING THAT I WOULD LIKE
TO POINT OUT IS -- LET'S SEE.00:17:15
LET ME FIND THE ASSET
IN THE CONTENT BROWSER.00:17:18
SEE THE ITEMS FOLDER
RIGHT HERE?00:17:22
IT IS VERY, VERY IMPORTANT.00:17:25
NO MATTER WHAT TYPE OF CONTENT00:17:26
YOU WILL MAKE FOR ACTION RPG,00:17:28
WHETHER IT IS A WEAPON,
A POTION, A SCALE, OR WHATEVER,00:17:32
IT HAS TO GO INSIDE OF
THIS FOLDER RIGHT HERE.00:17:34
IF YOU TRY TO PUT IT OUTSIDE
OF THE ITEMS FOLDER,00:17:37
IT WILL NOT BE ABLE
TO BE SLOTTED INTO THE INVENTORY00:17:40
THAT YOU SEE IN GAME.00:17:43
WHEN I GO IN GAME,
IF I HAVE IT IN THE FOLDER,00:17:46
I DON'T HAVE TO TOUCH THE UI
IN ANY WAY, SHAPE, OR FORM,00:17:48
IT WILL AUTOMATICALLY APPEAR00:17:50
AND BE SELECTABLE RIGHT HERE
WITHIN THE UI.00:17:54
THAT BECAUSE WE USE THE ASSET
MANAGER, IT RELIES ON PASS,00:17:59
SO IT IT IS LOOKING FOR ITEMS
IN THE POTIONS FOLDER00:18:02
TO ADD TO THE POTIONS SELECTION
INSIDE OF THE UI00:18:06
WHEN THE GAME IS PLAYING.00:18:07
THIS IS WHY THEY HAVE TO BE
LOCATED IN THESE FOLDERS.00:18:10
IF YOU TRY TO PUT THEM
OUTSIDE OF THE FOLDER,00:18:12
IT IS JUST NEVER GOING TO WORK.00:18:14
YOU CAN SEE THAT I HAVE
MY WEAPONS OVER HERE AS WELL,00:18:17
AND THAT'S THE --
THAT'S THE TOKENS,00:18:18
IT IS FOR THE SOULS
THAT YOU COLLECT,00:18:21
AND I HAVE THE SKILLS
HERE AS WELL.00:18:24
SO PAULO, IS THERE ANYTHING --00:18:26
>>PAULO: YES, OF COURSE,
ON THE ASSET MANAGE SIDE,00:18:29
YOU CAN CONFIGURE --
YOU CAN SET UP YOUR OWN FOLDERS00:18:33
THAT YOU WANT TO SEARCH
FOR PRIMARY ASSETS,00:18:37
FOR THE ASSET MANAGEMENT SYSTEM.00:18:41
SO ACTION RPG, I THINK, IF WE
JUST SCAN THE ITEMS FOLDER,00:18:46
AND ANY SUB-FOLDER IN IT.
IN YOUR OWN PROJECT,00:18:49
YOU CAN BASICALLY SET THAT UP
TO SCAN ANY TYPE OF FOLDER.00:18:54
IT IS IMPORTANT, AND IT IS --00:18:56
IF YOU WANT TO USE
THE ASSET MANAGES,00:18:58
IT IS IMPORTANT TO TAKE A LOOK
AT HOW WE DID IT,00:19:01
BECAUSE WE STILL NEED TO
IMPLEMENT SOME INTERFACES IN C++00:19:07
SO THE AGENT CAN ACTUALLY
LOAD ASSETS00:19:10
DYNAMICALLY WITHIN RUN TIME.00:19:14
TAKE A LOOK AT HOW WE DID IT,
WE TAKE A BASE CLASS00:19:17
THAT RESPONDS
TO THE SIMPLE INTERFACE,00:19:21
AND THEN YOU CAN LIST
THE ASSETS DYNAMICALLY,00:19:25
EVEN WHEN THE GAME
IS ALREADY RUNNING00:19:27
USING THE ASSET ASSET MANAGER,00:19:29
THAT HOW WE DID IT
WITH ACTION RPG.00:19:34
GETTING BACK TO THE EFFECTS, IT
IS IMPORTANT TO NOTICE THAT --00:19:38
SO SAM USED THE ATTACK
DAMAGE CURVE TABLE00:19:43
FOR THE NEW POTION ITEM
HE WAS SHOWING.00:19:46
IT IS ALSO IMPORTANT TO NOTE00:19:48
YOU CAN CREATE YOUR OWN
CURVE TABLE IF YOU WANT,00:19:54
WE ARE USING THAT CURVE TABLE
BECAUSE IT WAS ALREADY THERE00:19:58
AND WE WERE JUST TRYING
TO PROVE A POINT.00:20:00
BUT YOU CAN ACTUALLY CREATE
A DIFFERENT CURVE TABLE,00:20:03
WITH ANY BALANCE,
AND YOU CAN MIX00:20:06
AND MATCH TO THE SPECIFIC
NECESSITIES OF YOUR GAME DESIGN,00:20:10
THE GAME THAT YOU'RE WORKING.00:20:13
IT IS INTERESTING
BECAUSE THE GAME --00:20:15
THE SYSTEM ALREADY OFFERS
THAT FUNCTIONALITY00:20:19
THAT ENABLES YOU TO HAVE
NOT ONLY CROSSING --00:20:23
MAKING BUFFS AND DEBUFFS BASED
ON THE CHARACTER LEVEL,00:20:27
OR MAYBE THE ITEM LEVEL,
OR MAYBE YOU CAN HAVE,00:20:30
LIKE, ITEMS OR WEAPONS
THAT CAN BE UPGRADEABLE.00:20:32
IT IS UP TO THE DESIGNER
AND THE TEAM THAT IS WORKING IT,00:20:37
THE TOOLS THERE, AND --00:20:41
I MEAN, DEVELOPERS SHOULD
TAKE A LOOK00:20:42
AT HOW TO HOOK THEIR GAMES
AND IDEAS TO IT.00:20:47
>>SAM: YEP,
AND AGAIN, I DIDN'T00:20:49
WANT TO MAKE ANOTHER
CURVE TABLE,00:20:50
BECAUSE THAT ONE DID
WHAT I NEEDED TO DO.00:20:52
>>PAULO: YEP.00:20:53
>>SAM: SO REMEMBER,
THE MORE ASSETS YOU ADD,00:20:57
THE MORE ERRORS THAT CAN BE
INTRODUCED INTO YOUR PROJECT.00:21:01
I LIKE TO RE-USE AS MUCH
AS I POSSIBLY CAN.00:21:04
LET'S GO AHEAD,
WE TALK ABOUT THE POTION,00:21:07
AND TAKE A LOOK
AT THE SWORD NOW.00:21:08
THE SWORD IS EVEN LESS ASSETS,
IT IS A WEAPON BLUEPRINT.00:21:15
SO LET ME OPEN THIS UP,
AND YOU'RE GOING TO NOTICE00:21:17
IT IS ACTUALLY JUST A --00:21:20
SO WE'VE GOT SOME WEAPONS
DEFAULTS HERE00:21:22
AND, OTHER THAN THAT,00:21:23
IT IS PRETTY MUCH A DATA
ONLY BLUEPRINT.00:21:25
IF YOU DO WANT TO CHANGE
THE VISUALS,00:21:27
YOU WILL HAVE TO OPEN IN
TO THE FULL BLUEPRINT,00:21:30
AND GO TO THE VIEW PORT,
AND VOILA, THIS IS MY WEAPON.00:21:34
IT IS IMPORTANT TO NOTE,
I HAVE THIS CAPSULE COLLISION.00:21:37
THIS IS WHAT IS USED TO FIGURE
OUT IF I HIT SOMETHING.00:21:42
SO EVERY WEAPON
YOU ADD TO ACTION RPG,00:21:45
YOU NEED THIS CAPSULE COMPONENT
INSIDE OF IT,00:21:48
OR YOU CANNOT DO DAMAGE
TO ANYBODY.00:21:52
I WILL CLICK ON THE EVENT GRAPH,
I DON'T HAVE ANYTHING HERE,00:21:56
AND WHAT I WANT TO POINT OUT,00:21:57
IF YOU NEEDED THE WEAPON
TO DRIP FIRE,00:22:02
OR BLOOD, OR GLOW,
OR ANYTHING LIKE THAT,00:22:06
I COULD ACTUALLY DO
ALL OF THAT FUNCTIONALITY HERE00:22:09
WITHIN THIS EVENT GRAPH,00:22:11
SEPARATE FROM THE ABILITY
SYSTEM, AND IT WOULD JUST WORK.00:22:14
THIS IS A BLUEPRINT THAT
THE PLAYER GRABS ON TO,00:22:18
AND PUT INSIDE OF
THEIR INVENTORY.00:22:19
IT MAKES IT VERY SIMPLE
FOR ME TO DO, YOU KNOW,00:22:22
WEAPON EFFECTS
OR THINGS LIKE THAT00:22:24
WITHIN THIS PARTICULAR ASSET.00:22:28
THE OTHER THING I WANT TO SHOW
YOU, I WILL OPEN UP THIS --00:22:31
THIS IS OUR WEAPON SWORD.00:22:33
SO YOU CAN SEE
THE WEAPON ACTOR HERE00:22:35
IS THE BP_WEAPON_SWORD_TALON,00:22:39
THIS BLUEPRINT I HAD
IN THE COLLECTION OVER HERE.00:22:42
THE ITEM TYPE,
IT IS A DROP DOWN,00:22:44
SO YOU CAN CHANGE IT HERE,
WE HAVE A WEAPON.00:22:47
I GIVE IT A NAME, DESCRIPTION,
"IT IS SHARP, IT IS DANGEROUS,"00:22:50
IT HAS AN ICON, IT HAS A PRICE,
AND THESE ARE THE --00:22:54
BASICALLY THE COUNT,
THE MAX LEVEL,00:22:57
AND THIS SAYS ABILITY GRANTED.00:22:59
THIS IS IMPORTANT,
BECAUSE WHEN I CLICK ON THIS,00:23:02
IT IS GOING TO GO
INTO OUR SWORD.00:23:07
SO MAKING ANOTHER
GAMEPLAY ABILITY00:23:11
FOR THE SWORD IS A LOT OF WORK,00:23:15
IT TAKES A LONG TIME TO MAKE
AND IT IS VERY PRONE TO ERRORS.00:23:19
SO TO MAKE SOMETHING
THAT IS SIMPLIFIED,00:23:21
I GRABBED THE EXISTING ANIMATION00:23:25
AND
PUT THIS AS A NEW SWORD TO USE.00:23:28
THIS CUTS DOWN ON THE
AMOUNT OF ASSETS I HAVE00:23:30
AND THE AMOUNT OF ERRORS
I CAN MAKE.00:23:33
I ALSO HAD TO COME IN HERE
AND SAY, YOU KNOW WHAT,00:23:36
I WANT TO USE THIS,00:23:39
COME IN HERE, PLAY MY GAME,
AND THE SWORD --00:23:42
I WILL HIT THE TAB
TO OPEN UP THE UI,00:23:44
AND THE SWORD IS RIGHT THERE.00:23:47
SO IT IS SET UP IN A WAY
WHERE THINGS WOULD JUST WORK00:23:54
IF YOU PUT THEM
IN THE PROPER LOCATIONS --00:23:56
AND SIMPLY JUST -- FIND OUT,
WHAT WOULD I DO,00:24:00
WHERE DO I PUT IT,
FOLLOW THE FOLDER STRUCTURE.00:24:04
IF YOU PUT THINGS
WHERE YOU FIND THEM --00:24:06
SO IF I COME OVER HERE,00:24:08
AND I'M GOING TO PULL
MY COLLECTIONS DOWN,00:24:12
YOU CAN SEE THAT I'VE GOT,
YOU KNOW, THE FIRE ACTS,00:24:16
THE POTIONS, THE SKILLS,
I HAVE SOME SWORDS HERE.00:24:19
ALL I HAVE TO DO IS JUST --
YOU KNOW,00:24:22
IF I WANT TO DO SOMETHING
LIKE A DIFFERENT KICK,00:24:26
I CAN DUPLICATE THIS ASSET,00:24:29
THEN I CAN GO INTO,
THE DUPLICATED ONE,00:24:31
AND JUST CHANGE WHATEVER IT IS
THAT I FEEL I WANT TO CHANGE.00:24:35
SO LET'S SEE HERE.00:24:37
I CAN CHANGE THE DAMAGE
CALCULATION ON IT00:24:40
IF I WANTED TO,
I WILL KEEP ON GOING DOWN.00:24:45
I COULD ADD ANOTHER MODIFIER
ON TOP OF IT TO MODIFY00:24:49
WHATEVER DAMAGE IT'S DOING,
I COULD COME HERE00:24:52
AND I COULD CHANGE,
MAKE IT A DEFAULT ATTACK,00:24:54
OR A HEAVY ATTACKER,
WHATEVER I WANT TO DO,00:24:56
BASICALLY THIS IS GOING TO --00:24:57
THE DEFAULT ATTACK
AND THE HEAVY ATTACK,00:25:00
I THINK IT IS --
YEAH, DEFAULT, MEDIUM,00:25:02
AND HEAVY ARE JUST GOING TO --
ONE DOES 100, ONE DOES 200,00:25:06
AND ONE DOES 300, I THINK.
WELL, IT HAS BEEN A LITTLE WHILE00:25:10
SINCE I LOOKED
AT THE DATA TABLES,00:25:12
BUT THIS IS HOW YOU CONTROL
THE DAMAGE00:25:15
IT IS GOING TO BE APPLYING.00:25:17
BUT AGAIN,
IT'S NOT VERY COMPLICATED00:25:19
TO SET ALL THIS STUFF UP,
IF WHERE -- I --00:25:22
I WILL CLOSE THIS,
COME DOWN TO THE COLLECTIONS,00:25:28
IT IS THESE TWO ASSETS
THAT I HAD TO MAKE THIS.00:25:32
SO THE OTHER THING I WANT
TO SHOW YOU IS A PICK UP.00:25:36
LET ME OPEN UP THE PICK UP
BLUEPRINT REALLY QUICK.00:25:41
SO THE PICK UP --
SO IN THE TUTORIAL,00:25:46
IT IS LITERALLY JUST ADD
A LITTLE PIECE OF HAM.00:25:48
I DID A LITTLE BIT
OF EXTRA WORK HERE,00:25:53
AND I DID A LITTLE BIT,
IT LOOKS COMPLICATED,00:25:55
BUT IT IS VERY SIMPLE.00:25:57
LET ME PULL THIS OUT
TO THE LEVEL AND PULL THIS OVER.00:26:02
SO WHAT I CAN DO,
I CAN COME DOWN HERE00:26:05
AND CHANGE
THE POTION TYPE TO MANA,00:26:07
AND THEN WHAT IT'LL DO
IS CHANGE IT TO THE LOLLY POP,00:26:11
AND IT WILL ALLOW IT
TO ROTATE --00:26:13
I CAN COME BACK HERE
AND CHANGE IT TO A HEALTH ASSET00:26:16
AND YOU CAN SEE
THAT IT CHANGES IT BACK.00:26:20
THE REAL BREAD
AND BUTTER OF THIS SCRIPT00:26:22
IS IN THE EVENT SCRIPT.
SO WHAT ARE WE DOING HERE?00:26:24
SO WE HAVE THIS COMPONENT
ON ACTOR, BEGIN OVERLAP,00:26:28
IT IS A SPHERE COLLISION.00:26:29
YOU CAN SEE THERE'S
A SPHERE COLLISION RIGHT HERE.00:26:31
AND WHAT I WANT TO DO IS
WHEN I COLLIDE WITH THAT,00:26:35
I WILL SET A SLOTTED ITEM.
AND WHAT DO I WANT TO SET?00:26:37
I WANT TO SET A POTION,
AND A POTION TYPE.00:26:41
I WANT TO SET THE HEALTH
POTION.00:26:42
I WANT TO UPDATE
THE ON SCREEN CONTROLS,00:26:45
THIS WILL REFLECT
THAT I PICKED UP THE POTION,00:26:49
THEN I ADDED
A QUICK DELAY RIGHT HERE00:26:51
BECAUSE I WAS HAVING
SOME ISSUES SOMETIMES00:26:54
WHERE IT WOULD ACTUALLY
NOT DESTROY THE STUFF --00:26:59
I'M SORRY, ADD THE STUFF
BEFORE IT DESTROYED EVERYTHING.00:27:02
SO THIS .02 SECOND DELAY,
JUST MAKE SURE THAT00:27:06
WHEN I KILL THE LIGHT
AND I DESTROY THE ACTOR,00:27:08
ALL THE OTHER STUFF
HAS BEEN DONE FIRST.00:27:11
THIS IS THE ONLY LOGIC
THAT YOU NEED FOR THIS TO WORK.00:27:15
AND SO IF I COME HERE,
AND GO AHEAD AND PLAY,00:27:20
THERE WE GO.
WHOOPS.00:27:21
AND I WALKED OVER, YOU CAN SEE
THAT I'VE GOT IT IN MY --00:27:25
WHAT DOES THAT BUTTON SAY,
I CAN'T READ IT. IT IS TOO TINY.00:27:31
YEAH, F11. AH! THE R KEY.
SO NOW I CAN DO MY POTION.00:27:35
I WILL ESCAPE BACK OUT,00:27:38
AND I CAN ADD MULTIPLES
OF THESE TO THE LEVEL,00:27:41
I WILL CHANGE THIS
TO A MANA ASSET,00:27:45
HIT ALT+P ON THE KEYBOARD,
F11 TO FULL-SIZE IT --00:27:49
I GRABBED THE HEALTH ONE,
AND THE MANA ONE:00:27:54
HIT R, GET THE MANA -- HIT TAB,00:27:58
AND I COME OVER
TO THE HEALTH POTION,00:28:02
OH, I DON'T THINK
I HAVE ENOUGH MONEY.00:28:06
THERE WE GO.00:28:09
AND LET ME DO THIS
ONE MORE TIME,00:28:11
BECAUSE I THINK -- THERE WE GO.00:28:20
IT DID IT NOW.00:28:23
BUT IT LOOKS LIKE IT MIGHT NOT
HAVE UPDATED,00:28:25
I WILL GO BACK
AND HAVE A LOOK AT THAT ONE.00:28:29
WE MADE QUITE A FEW UPDATES
TO THIS PROJECT00:28:31
SINCE IT RELEASED WITH 4.20 --
WAS IT 4.20?00:28:35
4.21? --
I THINK IT WAS AROUND 4.20,00:28:43
WHICH BRINGS ME
TO ANOTHER POINT.00:28:47
NOW, YOU CAN USE THIS AS A BASIS
TO BUILD YOUR PROJECT OFF OF,00:28:50
BUT I WOULDN'T
RECOMMEND YOU DO THAT00:28:53
BECAUSE WE MAKE SOME MASSIVE,00:28:55
SWEEPING CHANGES TO THIS
EVERY SINGLE UPDATE,00:28:59
FOR THE UI EXAMPLE I SHOWED YOU
IN THE BEGINNING,00:29:01
I'M EXPANDING IT
AND CONTRACTING IT,00:29:04
WE COMPLETELY --
WELL, I SHOULDN'T SAY WE.00:29:06
PAULO COMPLETELY RE-WROTE
HOW THE UI FUNCTIONS00:29:11
AND, IN FACT, LET ME OPEN UP
THE BLUEPRINT AGAIN,00:29:14
THERE WERE OTHER CHANGES
THAT WERE MADE00:29:17
WHEN I HAD AN ENTIRELY
OTHER PIECE OF BLUEPRINT LOGIC00:29:20
THAT WAS OVER HERE
THAT MADE SURE00:29:22
THAT I UPDATED IT THE CORRECT
ITEM TYPE, THE CORRECT AMOUNT,00:29:25
BECAUSE IT WOULDN'T
DO IT AUTOMATICALLY,00:29:27
AND THERE WERE TWO NODES
WITH UPDATES00:29:29
THAT I CAN REMOVE THOSE OUT.00:29:31
>>AMANDA: OH, OKAY.00:29:32
>>SAM: SO IF YOU ARE USING
THIS TO BUILD A PROJECT FROM,00:29:37
I WOULD NEVER UPDATE IT --
>>AMANDA: HAHA.00:29:39
>>SAM: JUST TO DUMP OVER THE TOP
LIKE MOST PEOPLE DO00:29:42
WHEN THEY UPDATE, THEY GET
THE LATEST AND GREATEST,00:29:44
BECAUSE IT IS GOING TO BREAK
EVERYTHING IN YOUR PROJECT.00:29:48
YOU WILL HAVE
A VERY BROKEN PROJECT.00:29:49
WHAT YOU SHOULD BE DOING
IS USING THIS AS A LEARNING TOOL00:29:53
TO ADD NEW WEAPONS, POTIONS,
MAYBE ADD ENEMY TYPES,00:29:56
OR WHATEVER YOUR HEART DESIRES,00:30:00
FIGURE OUT HOW THE SYSTEMS
WORK WITH ONE ANOTHER,00:30:02
BECAUSE YOU HAVE AN EXAMPLE,00:30:03
A COMPLETE EXAMPLE
OF HOW THIS WORKS TOGETHER00:30:05
AND TAKE THIS KNOWLEDGE
AND APPLY IT TO THE PROJECT.00:30:10
PAULO, ANYTHING
YOU WOULD LIKE TO ADD.00:30:12
>>PAULO: YEAH, DEFINITELY AGREE
THAT YOU SHOULD TAKE A LOOK00:30:17
AT THE SYSTEMS WE BUILT
FOR THIS PROJECT,00:30:20
HOW WE USE THE ABILITY SYSTEM,00:30:22
HOW WE MADE INVENTORY SYSTEM
FOR THE CHARACTER,00:30:26
AND USE IT AS A REFERENCE.00:30:28
THAT IS 100 PERCENT AGREE
ON THAT.00:30:30
AND YOU CAN ACTUALLY
COPY THE CODE WE DID,00:30:34
YOU CAN COPY THE FUNCTIONALITY
OF EVERYTHING,00:30:37
BUT TRY TO INTEGRATE
THAT IN YOUR OWN PROJECT00:30:42
INSTEAD OF JUST TRYING TO SYNC
FOR EVERY VERSION00:30:46
THAT WE RELEASE
OF ACTION RPG,00:30:48
BECAUSE WE WILL DEFINITELY BE
BREAKING THINGS GOING AHEAD,00:30:52
SOME THINGS ARE
GOING TO BE CHANGED.00:30:54
THE IDEA FOR THIS PROJECT00:30:55
IS DEFINITELY THAT WE KEEP IT
AS AN EXAMPLE00:31:02
OF SOME OF THE BEST PRACTICE
WE WANT DEVELOPERS TO USE.00:31:05
SO IT WILL ALWAYS BE CHANGING,00:31:08
ACCORDING TO ENGINE CHANGES
IN DEVELOPMENT.00:31:14
>>SAM: OKAY.00:31:15
SO THE NEXT THING I WANT TO TALK
ABOUT IS,00:31:17
LET ME GO AHEAD
AND PLAY IT AGAIN REAL QUICK,00:31:19
AND WE WILL DO THE NIFTY
F11 TRICK.00:31:24
I WILL CHANGE THIS WEAPON
HERE REALLY QUICK,00:31:26
BECAUSE I WANT TO VANQUISH
MY ENEMY ENEMIES A LOT FASTER.00:31:30
OH, THE SCROLL WHEEL CHANGES
YOUR WEAPON NOW.00:31:34
WHEN I KILL THIS GUY,00:31:36
YOU CAN SEE THAT I ONLY
HAVE ONE SOUL, BUT LET'S SEE.00:31:41
NOW I HAVE TWO,
AND THEN I GOT ONE AGAIN.00:31:44
SO ORIGINALLY, YOU WERE
JUST AWARDED ONE SOUL AT A TIME.00:31:49
BUT THAT MADE PROGRESSING IN THE
GAME EXTRAORDINARILY PAINFUL,00:31:54
YOU WOULD HAVE TO PLAY MULTIPLE
TIMES OVER MULTIPLE SESSIONS00:31:58
JUST TO GET ENOUGH
TO BUY A BRAND-NEW WEAPON,00:32:00
UNLESS YOU DID A CHEAT AND GAVE
YOURSELF 100 SOULS AT A TIME.00:32:05
SO TO MAKE THINGS
MORE INTERESTING FOR PEOPLE00:32:08
AND TO SHOW HOW YOU
CAN MODIFY THE00:32:10
BASE LEVEL CLASS OF SOMETHING00:32:12
AND HAVE THE CHANGES
PROPAGATE UP TO00:32:14
OTHER INSTANCES
BASED OFF OF THIS,00:32:16
I ADDED THE FOLLOWING
LOGIC TO THIS ENEMY.00:32:21
SO YOU HAVE THE LOOT SPAWN00:32:23
AND BASICALLY THIS IS GOING
TO SPAWN THOSE ORBS,00:32:26
IT IS GOING TO SPAWN THE ORBS,
BUT WE WILL --00:32:31
THIS IS THE LOCATION,
THIS IS THE ORB,00:32:33
AND THEN WHAT WE DO HERE IS,
IN THE EVENT GRAPH,00:32:36
WHEN IT'S DESTROYED --00:32:37
SO WHEN THIS CHARACTER
HAS BEEN VANQUISHED,00:32:40
WE ARE BASICALLY
GOING TO SPAWN THE LOOT,00:32:42
BUT WE ARE GOING TO GIVE IT
A MIN AND A MAX VALUE.00:32:44
SO RIGHT NOW, THE MIN AND THE
MAX SETS ARE 1 AND 1.00:32:47
WE ARE USING A RANDOM
INTEGER IN RANGE.00:32:50
SO WE ARE BASICALLY SAYING,
I WANT YOU TO SPAWN00:32:53
A RANDOM AMOUNT OF SOULS
BETWEEN ONE AND ONE,00:32:56
FOR THE BASE LEVEL CLASS,
SO IT WILL SPAWN ONE.00:32:58
AS YOU PROGRESS, AND LET ME PULL
UP ANOTHER CHARACTER HERE --00:33:04
SO LET'S SEE, OOPS.00:33:06
THIS MOUSE IS SO SENSITIVE.00:33:12
LET'S SEE IF I CAN FIND --00:33:14
SO WE WILL DO
THE NPC LEVEL THREE.00:33:17
SO THIS GUY -- AND NOW,
THERE IS NOTHING IN THE GRAPH,00:33:20
BUT YOU CAN SEE
I HAVE A SOUL MIN00:33:21
AND A SOUL MAX
BETWEEN 3-5.00:33:24
WHAT I HAVE DONE HERE IS AT
THE BP_ENEMYCHARACTER LEVEL,00:33:29
I HAVE ESTABLISHED I WANT
TO ACCESS SOUL MIN AND SOUL MAX,00:33:34
AND THEN I BASICALLY PROPAGATED
THE CHANGES UP THROUGH LEVEL00:33:37
ONE, LEVEL TWO, LEVEL THREE.
THIS WAY, I CAN GIVE --00:33:40
I DO BELIEVE LEVEL ONE HAS 1-3,
LEVEL TWO IS, LIKE, 4-6,00:33:46
AND THEN WHAT IS THIS ONE,
I CAN TELL YOU, 3-5.00:33:50
AND THE BIG SPIDER BOSS
GIVES YOU 10 SOULS.00:33:55
THIS IS HOW YOU WORK --00:33:58
YOU SHOULD BE WORKING
INSIDE OF YOUR BLUEPRINTS,00:34:00
OR YOUR C++ CODE
OR WHATEVER IT IS.00:34:02
YOU WANT TO ESTABLISH STUFF
INSIDE OF YOUR BASE CLASS,00:34:05
FOR A NUMBER OF REASONS.00:34:06
ONE, FOR EXAMPLE, THIS FUNCTION,
SPAWN LOOT, DID NOT EXIST00:34:12
BEFORE, THROUGH REFACTORING,
PAULO WAS LIKE,00:34:15
"HEY, YOU NEED TO PUT THIS --
YOU NEED TO TAKE THIS OUT00:34:20
AND PUT IT INTO ITS OWN FUNCTION
AND WE NEED TO CALL IT."00:34:24
BECAUSE I BUILT IT
INTO THIS CLASS,00:34:26
ALL I HAD TO DO
WAS COME DOWN HERE,00:34:28
IMPLEMENT THIS, SPAWN THE AMOUNT
OF SOULS PER KILL,00:34:34
AND THE CHANGE PROPAGATED
TO ALL OF MY BLUEPRINTS.00:34:38
SINCE I SET THE SOUL MIN
AND SOUL MAX UP TO 3 AND 5,00:34:41
I DIDN'T HAVE TO OPEN EACH ONE
OF MY BLUEPRINTS TO DO THIS.00:34:45
IN A PROJECT THIS SIZE, THAT
IS 20 OR 30 MINUTES OF WORK.00:34:51
IN A PROJECT
THE SIZE OF FORTNITE,00:34:54
THAT'S A COUPLE DAYS OR A
COUPLE WEEKS' WORTH OF WORK,00:34:57
DEPENDING ON HOW PREVALENT
THE CHANGES ARE.00:34:59
>>AMANDA: AND YOU MIGHT
MISS SOMETHING.00:35:01
>>SAM: OR YOU DO 1-3,
AND FORGET ABOUT 4,00:35:05
BECAUSE SOMEBODY CAME IN
AND ASKED YOU TO DO SOMETHING,00:35:08
YOU DID IT, AND YOU MOVED ON.00:35:10
SO ADDING STUFF
IN THE BASE LEVEL CLASS00:35:12
IS HOW YOU SHOULD BE SETTING UP
ALL OF YOUR BLUEPRINTS00:35:16
IF THEY ARE USED AS A BASE
TO BUILD SOMETHING ELSE.00:35:20
YOU DON'T HAVE TO DO THIS
WITH EVERY SINGLE BLUEPRINT,00:35:23
BUT THIS IS A GOOD EXAMPLE
OF WHAT YOU SHOULD BE DOING00:35:26
WHEN YOU HAVE SOME BASE
LEVEL FUNCTIONALITY00:35:30
THAT EVERYBODY CAN USE.00:35:31
>>AMANDA: UH-HUH.00:35:33
>>SAM: AND, OF COURSE,
YOU CAN GET WAY MORE00:35:35
COMPLEX WITH THIS, BUT
THIS IS A GOOD KIND OF --00:35:37
IF YOU WANT TO TAKE
YOUR BLUEPRINT SKILLS00:35:39
TO THE NEXT LEVEL,
YOU ARE NOT SURE WHERE TO GO,00:35:42
THIS IS A GOOD PROJECT
TO LOOK AT00:35:43
BECAUSE THERE'S TONS OF THINGS
LIKE THIS00:35:45
SCATTERED ALL OVER
THE BLUEPRINTS IN THIS PROJECT.00:35:49
PAULO, ANYTHING YOU WOULD LIKE
TO ADD ABOUT THIS?00:35:55
>>PAULO: YEAH, I --
I TOTALLY AGREE WITH THAT.00:35:58
BLUEPRINTS IS REALLY SOMETHING00:36:00
THAT WAS BUILT
FROM GROUND TO BE --00:36:03
TO HELP US ON SETTING THE DATA
ON OBJECTS IN THE GAME.00:36:08
SO IT IS REALLY --
IT IS NOT ONLY CONNECTING CODE,00:36:11
IT IS HEAVILY USED
FOR DATA STORAGE.00:36:16
YOU SHOULD MAKE GOOD USE
OF THAT, THIS KIND OF THING,00:36:21
IF YOU DO -- IF YOU ARE SHOWING
THE INHERITANCE,00:36:24
IT IS REALLY USEFUL FOR
LARGER PROJECTS LIKE THAT.00:36:31
>>SAM: OKAY.
SO --00:36:33
>>PAULO: ONE SMALL
THING I WANTED TO ADD,00:36:35
ABOUT THE WEAPONS.
WE HAD TO DO A MINOR CHANGE00:36:40
ON THE ARCHITECTURE
FROM VERSION ONE.00:36:44
INITIALLY THE ABILITY SYSTEM
USED PLAYER LEVEL00:36:51
TO CHANGE THE WEAPON DAMAGES.00:36:55
ORIGINALLY, WE WERE
TRACKING THE PLAYER LEVEL.00:36:58
THERE WAS ACTUALLY A VARIABLE
OF PLAYER LEVEL00:37:01
IN THE CHARACTER BLUEPRINT.
WE DIDN'T USE THAT FOR ANYTHING,00:37:04
BECAUSE WE DON'T HAVE PLAYER
UPGRADES YET.00:37:07
THAT MAY BE SOMETHING
THAT MAY COME IN THE FUTURE,00:37:09
OR MAY BE SOMETHING YOU WANT
TO EXPERIMENT IN YOUR GAME,00:37:14
LIKE THE SYSTEM THAT UPGRADES
THE PLAYER LEVEL.00:37:18
BUT WE USE THAT VARIABLE00:37:22
TO CHANGE THE DAMAGE
OF THE WEAPONS,00:37:26
AND WE HAD TO MAKE
A SLIGHT CHANGE00:37:29
TO ALLOW WEAPONS TO HAVE
UPGRADES ON THIS VERSION.00:37:33
SO NOW WHEN YOU ATTACK AN ENEMY,00:37:36
THE WEAPON ITSELF HAS A LEVEL,
A VARIABLE,00:37:40
AND IT USES THAT LEVEL --
THAT WEAPON LEVEL VARIABLE00:37:44
TO PICK THE RIGHT AMOUNT
OF DAMAGE00:37:46
THAT IT IS GOING
TO INFLICT ON THE ENEMY.00:37:49
AND THAT ALSO MAKES IT
MUCH EASIER FOR YOU00:37:54
TO COME UP WITH NEW KINDS
OF WEAPONS AND NEW LEVELS.00:37:59
I THINK IN THE CURRENT TABLE,
IT GOES TO 10, WE USE 1-3,00:38:04
THAT IS NICE IF WE PLAY AROUND
WITH THIS SAMPLE PROJECT,00:38:10
LOOKING AT THAT.00:38:12
>>SAM: OKAY.00:38:13
SO THE ONE THING
THAT YOU MIGHT BE NOTICING00:38:16
THAT I DON'T ACTUALLY HAVE
ANY DOCUMENTATION ABOUT00:38:19
IS ADDING A NEW SKILL.00:38:21
AND THE REASON FOR THIS
IS BECAUSE ADDING A NEW SKILL,00:38:23
SO SKILLS ARE -- LET ME --00:38:25
FOR THOSE OF YOU
THAT ARE NOT AWARE.00:38:27
AND WE WILL DO
OUR LITTLE F11 TRICK HERE,00:38:30
CALL IT THE VICTOR CHEAT.
IT IS DEFAULT.00:38:35
IF I HIT F HERE, YOU CAN SEE
THAT I DO A FIREBALL.00:38:37
SO THAT'S A SKILL,
THAT'S WHAT WE'RE TALKING ABOUT.00:38:40
IF I HIT TAB HERE,
GO OVER TO SKILLS,00:38:42
YOU HAVE A METEOR SHOWER --
F AGAIN,00:38:48
AND IT IS A CRAZY AOE ATTACK,
A LOT OF HEAVY DAMAGE,00:38:53
IT COSTS A LOT OF MANNA,
I KEEP DOING IT00:38:56
BECAUSE I KEEP HITTING
THE ATTACK BUTTON TO SHOW YOU.00:39:00
BUT THE REASON I DON'T HAVE
ANY DOCS ABOUT THIS,00:39:02
IT IS NOT JUST AS SIMPLE00:39:04
AS DUPLICATING
A CURRENTLY EXISTING ASSET,00:39:09
IT REQUIRES NEW ANIMATIONS,00:39:11
IT WILL REQUIRE A LITTLE BIT OF
THINKING ABOUT THE TYPE OF THING00:39:14
THAT I WANT TO DO, LIKE,
WE HAVE FIREBALLS AND AOES,00:39:18
WHAT IF I WANTED TO HAVE
A FIREBALL THAT SPAWNED AN AOE,00:39:22
OR I WANTED THE PLAYER
TO SHOOT A BOW AND ARROW,00:39:27
THERE'S A BUNCH OF DESIGN WORK
THAT NEEDS TO GO INTO THESE,00:39:31
WHICH THAT IS A LITTLE
SUBJECTIVE.00:39:35
THAT'S WHY WE DON'T HAVE
ANY DOCS ABOUT THIS.00:39:37
BECAUSE THERE IS A WHOLE BUNCH
OF OTHER DECISIONS00:39:41
THAT NEED TO GO IN,00:39:42
YOU CANNOT JUST ADD
A SKILL TO YOUR GAME,00:39:44
BECAUSE WHAT IT IF IT MAKES
THE GAME SUPER IMBALANCED,00:39:47
AND THAT IS SOMETHING
THAT WILL HAPPEN, RIGHT?00:39:49
IF I'M WILLY-NILLY ADDING A
SKILL TO THIS, ALL OF A SUDDEN,00:39:52
IF I HAVE A FIRE BALL00:39:54
THAT SPAWNS OTHER FIRE
BALLS DOING 500 DAMAGE,00:39:57
WHY AM I GOING TO PICK ANY OTHER
WEAPON IN THE GAME TO PLAY WITH,00:40:00
IF I AM USING A FINGER
OF GOD TYPE OF WEAPON?00:40:04
SO THAT'S NOT TO SAY THAT
YOU CAN'T ADD ADDITIONAL SKILLS00:40:10
AND MIX
AND MATCH THE CURRENT ANIMATIONS00:40:11
AND THINGS LIKE
THAT THAT WE HAVE WITH THE GAME00:40:14
TO ADD A NEW SKILL,
IT IS JUST --00:40:16
WE DIDN'T DOCUMENT IT BECAUSE,
ONE, WE DIDN'T HAVE TIME00:40:19
TO COME UP WITH A NEW SKILL
TO TEST TO MAKE SURE00:40:22
THAT IT IS NOT UNBALANCING
THE GAME AS IT CURRENTLY IS.00:40:27
BUT IF YOU DID WANT TO ADD ONE,
WE COME TO THE SKILLS,00:40:30
AND YOU CAN SEE --
OUR FIREBALL,00:40:32
THIS IS ONE OF THE THINGS
THAT I SHOULD POINT OUT,00:40:35
WE HAVE A BP ABILITY
PROJECTILE BASE.00:40:39
THIS IS SUPER IMPORTANT,00:40:40
SO THERE IS NO BLUEPRINT LOGIC
IN THIS,00:40:42
IT IS JUST OUR SPHERE CAPSULE,00:40:47
WE HAVE PROJECTILE MOVEMENT
ON HERE, THE ARROW COMPONENT,00:40:51
THE PARTICLE SYSTEM,
AND SOME AUDIO.00:40:54
IF WE COME UP HERE
AND WE OPEN UP THE METEOR, YEAH.00:41:02
SO THE METEOR SCALE,
WHICH IS THE ONE00:41:04
THAT DOES THE AOE,
THIS IS FROM GA SKILL BASE,00:41:08
SO IT IS BASED OFF
OF A DIFFERENT CLASS.00:41:11
IF I COME TO, LET ME SEE,
THERE IS -- HMM.00:41:19
I THINK THIS SKILL?00:41:22
HOLD ON A SECOND.00:41:24
SO LET ME PULL OVER --
WHAT I'M LOOKING FOR00:41:26
IS BASICALLY ON THE FIREBALL,
THERE'S AN INPUT,00:41:29
AND I DON'T REMEMBER
WHICH FILE IT WAS ON.00:41:33
BASICALLY, WHEN YOU ARE
MAKING A PROJECTILE STYLE SKILL,00:41:39
YOU MAKE THE PROJECTILE
AND THIS IS SLOTTED INTO --00:41:44
I WILL GET TO THIS GUY.
I CAN'T SEE THE FIREBALL.00:41:49
I WILL SEE
IF I CAN FIND IT IN HERE.00:41:52
AND THAT IS NOT --00:41:54
>>PAULO: MAYBE THE ABILITY?
>>SAM: THE ABILITY?00:41:56
>>PAULO: THE FIREBALL ABILITY,
YEAH.00:41:59
>>SAM: OKAY.00:42:03
I FEEL SO OLD AND BLIND TRYING
TO LOOK AT ALL OF THIS STUFF.00:42:07
>>PAULO: IT IS GETTING
COMPLICATED WITH TIME.00:42:09
>>SAM: YEAH.00:42:11
>>PAULO: SO PLAYER --00:42:12
>>AMANDA: WELL, YOU ARE
STILL SEARCHING IN SKILLS,00:42:14
IS THAT WHERE YOU WANT TO BE?00:42:15
>>SAM: YES.
>>PAULO? IS IT SKILL FIREBALL?00:42:23
>>PAULO: SHOULD BE --00:42:24
>>SAM: YEAH, HERE WE GO.00:42:25
>>PAULO: GA,
PLAYER, SKILL FIREBALL.00:42:28
>>SAM: THE PROJECTILE CLASS.
SO BASICALLY, THIS HAS00:42:32
GA SPAWN PROJECTILE BASE,
WHICH IS THE BLUEPRINT,00:42:36
WHICH IS JUST SLIGHTLY DIFFERENT
THAN THE MELEE ONES,00:42:39
AND THE ONLY DIFFERENCE
BETWEEN THESE TWO00:42:42
IS YOU WILL SEE THIS PROJECTILE
CLASS INPUT RIGHT HERE.00:42:44
THE ONLY DIFFERENCE, EVERYTHING
ELSE IS SET UP EXACTLY THE SAME,00:42:48
BUT YOU NEED TO SLOT
THIS PROJECTILE BLUEPRINT00:42:52
INTO THIS LOCATION RIGHT HERE.00:42:55
>>PAULO: THE MAIN DIFFERENCE
BETWEEN ANIMATION AS A SKILL,00:43:02
AND THE FIREBALL IS,
AT THE END OF THE --00:43:06
NOT AT THE END, BUT AT
THE BEGINNING OF THE ANIMATION,00:43:10
THE ABILITY SPAWNS
A DEAD ACTOR.00:43:14
THAT IS SIMPLY THAT DIFFERENCE.00:43:17
INSTEAD OF WAITING
FOR ANY SORT OF ANIMATION EVENT,00:43:21
THE COLLISION CHANNELS WILL
TRIGGER AND00:43:23
AND THEY WILL APPLY DAMAGE.00:43:25
THAT ACTOR ITSELF
IS GOING TO APPLY DAMAGE00:43:28
TO AN ENEMY WHEN IT HITS --
WHEN IT HITS IT.00:43:31
SO IT IS A SLIGHT DIFFERENCE,
AND IT WORKS ABOUT THE SAME,00:43:36
BUT I MEAN -- IT IS
DIFFERENT ANYWAY. YEP.00:43:39
>>SAM: IT IS DIFFERENT ENOUGH FOR US
TO CALL OUT00:43:43
BECAUSE THERE ARE GOING TO BE --00:43:46
THAT IS ONE THING
THAT I WANT TO TOUCH ON.00:43:47
I HAVE NOT TESTED ALL OF THESE
FEATURES THAT ARE IN HERE.00:43:50
SO SOME OF THIS STUFF
COULD WORK,00:43:52
SOME OF IT COULD NOT WORK,00:43:53
IF YOU DO FIND SOMETHING
THAT DOESN'T WORK,00:43:55
OR IS NOT WORKING THE WAY
YOU FEEL THAT IT SHOULD,00:43:58
PLEASE LET US KNOW00:44:00
AND WE CAN TAKE A LOOK AT IT
AND SEE --00:44:02
MAYBE IT IS NOT HOOKED UP,
THE CONTENT IS THERE,00:44:06
BUT THERE IS NOTHING HOOKED UP
IN THE BACK END IN THE C++,00:44:09
BECAUSE THIS IS NOT JUST --00:44:12
THE ABILITY SYSTEM HERE
IS VERY, VERY COMPLEX.00:44:15
AND WE'VE REALLY ONLY KIND OF
SCRATCHED THE VERY, VERY SURFACE00:44:19
OF HOW COMPLEX
YOU CAN GET THESE.00:44:21
I MEAN,
YOU CAN HAVE THIS ABILITY --00:44:24
YOU CAN HAVE THE PLAYER
FIREBALL SKILL00:44:26
DO SOMETHING LIKE
STACK POISON DAMAGE ON SOMEBODY.00:44:30
BASICALLY IF YOU ARE FAMILIAR
WITH ANY TYPE OF MMO00:44:33
THAT HAS COMPLEX SKILLS,
LIKE EVERQUEST,00:44:35
WOW, OR STAR WARS,
OR ANY MMO, PERIOD,00:44:40
THIS IS A VERY,
VERY SIMILAR SYSTEM00:44:42
TO THE TYPES OF SYSTEMS
THAT WOULD BE DEPLOYED00:44:45
IN THOSE STYLE OF GAMES,
BECAUSE A LOT OF THOSE PEOPLE00:44:47
THAT MADE THOSE STYLE OF
GAMES WORK HERE AT EPIC00:44:49
THAT'S WHAT PRODUCED
THE ABILITY SYSTEM.00:44:54
LET ME SEE,
WHAT ELSE DO WE HAVE HERE.00:44:57
THAT'S PRETTY MUCH
ALL THAT I HAVE.00:44:59
LET ME GO BACK OVER MY DOCS
REAL QUICK, MY NOTES HERE.00:45:05
YEAH, THAT'S A GOOD RUNDOWN OF
EVERYTHING GOING ON HERE.00:45:10
SO IF PAULO DOESN'T HAVE
ANYTHING ELSE TO ADD,00:45:12
WE WILL START OPENING IT UP
TO SOME QUESTIONS.00:45:15
WE HAVE QUITE A FEW -- OKAY.
PAULO, DO YOU HAVE ANYTHING ELSE00:45:19
YOU WOULD LIKE TO ADD
BEFORE WE JUMP INTO QUESTIONS?00:45:22
>>PAULO: NOPE, I'M GOOD.
>>SAM: ALL RIGHT.00:45:28
>>VICTOR: HOW WOULD YOU MAKE
AN EQUIP ITEM, CHANGE, OR STATS,00:45:31
SUCH AS INCREASING ATTACK POWER?00:45:33
>>SAM: UH-HUH, OKAY.00:45:36
I DO BELIEVE -- ISN'T THAT
UNDER THE WEAPON ABILITY,00:45:45
OR THE ABILITY LEVEL, PAULO?00:45:48
>>PAULO: YES, YOU COULD CHANGE
THE ABILITY LEVEL, SORRY --00:45:56
YOU CAN ACTUALLY CHANGE
THE CHARACTER LEVEL.00:46:00
AND THEN THE PLAYER,
THE CHARACTER ITSELF,00:46:03
WHEN IT INITIALIZES,
IT GOES AFTER THIS DATA TABLE00:46:08
AND APPLY -- YOU ACTUALLY APPLY
A DEFAULT STATS EFFECT,00:46:12
AND THIS DEFAULT STATS EFFECT
GOES AFTER THIS DATA TABLE,00:46:17
THE DEFAULT MANA AND DEFAULT
HEALTH TO THE CHARACTER.00:46:24
TO ADD MORE DAMAGE TO MAKE
THE GAME MORE POWERFUL, YES,00:46:31
YOU WOULD NEED TO ADD SOME SORT
OF MULTIPLIER TO THE DAMAGE,00:46:37
FOR EVERY WEAPON, YOU NEED
TO HAVE SOME SORT OF MULTIPLIER.00:46:40
AND WHILE WE HAVE
ABILITY EQUIPPED,00:46:44
YOU BASICALLY HAVE TO GO TO THE
WEAPON AND SAY, "HEY, THIS --00:46:51
I HAVE VISIBILITY, SO YOU NEED
TO ADD THIS AMOUNT OF DAMAGE,00:46:57
BONUS DAMAGE,
ON YOUR NEXT ATTACK,00:47:00
BECAUSE I HAVE SUPER POWERS
NOW."00:47:03
AND WE DON'T HAVE THAT
BY DEFAULT ON OUR SYSTEM,00:47:07
IT IS A LITTLE CONVOLUTED
TO ADD THIS SUPPORT,00:47:11
BUT THAT SHOULD BE DOABLE.
I WILL GO AFTER -- ACTUALLY,00:47:15
LOOKING AT THE BLUEPRINTS
FOR MELEE ATTACKS,00:47:20
AS AN EXPERIMENT,
AND I WILL LOOK00:47:22
AT HOW WE APPLIED THE DAMAGE
OVER THERE AND HOW WE COLLECT00:47:26
AND GATHER THE ACTUAL DAMAGE
IN THE C++ CODE00:47:32
AND TRY TO HOOK
YOUR OWN VARIABLE00:47:34
FOR MAYBE BONUS DAMAGE,
OR SOMETHING LIKE THAT,00:47:38
AND THEN ACTIVATE
THE BONUS DAMAGE,00:47:44
DEPENDING ON THE STATUS --00:47:46
DEPENDING IF YOU HAVE
ANOTHER ABILITY OR NOT.00:47:48
THAT WOULD BE THE RIGHT WAY
OF DOING THAT.00:47:51
>>SAM: AND THEN THERE'S ALSO,
ON THE WEAPON ACTOR HERE,00:47:54
THERE'S THE ABILITY LEVEL.00:47:56
AND I DO BELIEVE
THE MORE YOU INCREASE THIS,00:47:58
THE MORE DAMAGE
YOU ARE SUPPOSED TO GIVE.00:48:01
>>PAULO: YES. I'M NOT SURE,
IF YOU CREATE THIS IN RUNTIME,00:48:06
IT WILL APPLY MORE DAMAGE.00:48:09
>>SAM: YEP, YOU READ MY
MIND.00:48:11
I'M NOT 100 PERCENT SURE
IF THIS WILL --00:48:14
IF YOU COULD OPEN THIS UP
AND GRAB THE ABILITY LEVEL00:48:17
FROM THE WEAPON_
AXE_2 - GENERIC,00:48:22
AND THEN INCREASE
THAT AT RUNTIME.00:48:24
>>PAULO: YEAH, IF
YOU DO THAT -- SORRY.00:48:28
>>SAM: OR BASICALLY
RAMP IT UP FROM ONE TO FIVE00:48:31
AND THEN BACK DOWN TO ONE SOUNDS
LIKE IT COULD BE DOABLE,00:48:33
BUT I HAVE NEVER TRIED THAT.00:48:35
>>PAULO: YEAH, IT COULD BE
DOABLE, BUT I AM JUST NOT SURE00:48:37
IF THE SYSTEM IS HOOKED UP
TO UPDATE THAT LIVE.00:48:42
BUT IT WOULDN'T BE LIKE THAT
COMPLICATED TO GO THAT PATH.00:48:47
JUST MAKE AN UPDATE FOR EVERY
HIT YOU ARE TRYING TO MAKE,00:48:50
CHECK THE LEVEL OF THAT WEAPON,
IF IT IS HIGHER,00:48:54
YOU PICK THE RIGHT LEVEL
AND THE RIGHT DAMAGE,00:48:56
IT IS GOING TO APPLY,00:48:58
AND THEN YOU CHANGE
IT MAYBE ON A COOL DOWN,00:49:02
OR ANOTHER ITEM THAT IS EQUIPPED
TO THE CHARACTER.00:49:10
>>SAM: I HOPE THAT ANSWERS
THEIR QUESTION.00:49:12
>>VICTOR: SO
YOU NEED TO DO A00:49:13
LITTLE BIT MORE
WORK, ESSENTIALLY.00:49:17
THIS ONE IS KIND OF COOL, AND
SO I WAS WONDERING ABOUT, TOO.00:49:19
HOW DO YOU MAKE A GAMEPLAY ABILITY
THAT TAKES SPECIAL INPUT,00:49:24
SUCH AS THE FIRST BUTTON PRESS,
THROW A SET OF MINE,00:49:26
AND THE SECOND PRESS,
THAT DETONATES IT?00:49:29
THAT IS PROBABLY AN EVENT
DISPATCHER ON THE MINE ITSELF?00:49:35
>>SAM: YEAH. AND PAULO,
CORRECT ME IF I'M WRONG,00:49:40
WE WERE TALKING
ABOUT THIS BEFOREHAND,00:49:41
BECAUSE WE WANT TO ADD SOMETHING
WHERE, LIKE,00:49:45
THE METEOR SKILL RIGHT NOW
JUST DOES IT AROUND YOU LOCALLY,00:49:48
BUT IT WOULD BE COOL IF WE CAN
HAVE YOU MOVE THE MOUSE AROUND,00:49:51
OR YOUR FINGER AROUND,00:49:52
AND HAVE IT BE MORE
FOR CROWD CONTROL,00:49:55
SO I'M KILLING THESE ENEMIES
DOWN HERE00:49:57
WHILE I BATTLE
THESE ENEMIES OVER HERE.00:50:02
>>PAULO: YEP.
>>SAM: AND THE --00:50:04
BECAUSE IT COULD BE
AN ACTUAL BLUEPRINT00:50:06
YOU THROW OUT
INTO THE WORLD00:50:08
MAKES THINGS A LOT EASIER,00:50:09
BECAUSE YOU CAN ADD LOGIC
FOR THE INPUTS ON THAT.00:50:14
YOU CAN HAVE THAT MINE LISTENING
FOR RIGHT MOUSE BUTTON,00:50:18
OR DETONATION,
OR SOMETHING LIKE THAT.00:50:21
WHICH IS, SAY,
A LITTLE BIT EASIER00:50:24
THAN IF YOU HAD EVERYTHING
INCLUDED IN ONE ABILITY,00:50:28
YOU HAD THE ABILITY
AND THE SLOTTED STUFF IN,00:50:31
INSTEAD OF IT BEING MODULARIZED.
I FOUND THAT IN DOING THIS,00:50:35
THE MODULARIZATIONS --
THE PICK UPS, FOR EXAMPLE,00:50:39
THAT ISN'T SOMETHING
THAT WE HAD PLANNED,00:50:41
WE BUILT IT INTO BLUEPRINTS.00:50:43
BECAUSE THE SYSTEM IS MODULAR
AND YOU CAN ACCESS00:50:46
ALL OF THE NODES
YOU NEED INSIDE OF THE DAMAGE00:50:50
AND UPDATE THE INVENTORY
AND ALL OF THAT STUFF,00:50:52
IT IS A COUPLE OF DAYS
OF MESSING AROUND TO DO IT.00:50:56
PAULO, IS THERE ANYTHING
YOU WOULD LIKE TO ADD ON THAT?00:50:59
>>PAULO: I WOULD TAKE A
LOOK AT THE FIRE BALL ABILITY,00:51:05
BECAUSE IT ACTUALLY SPAWNS
ANOTHER ACTOR.00:51:10
IT IS A --
IT IS A LITTLE BIT DIFFERENT,00:51:11
BUT YOU CAN GO FROM THERE,00:51:13
IT SPAWNS ANOTHER ACTOR
THAT HAS A CONSTANT VELOCITY,00:51:16
BECAUSE IT WORKS
AS A PROJECTILE.00:51:18
BUT NOTHING REQUIRES THAT IT --
IT NEEDS TO HAVE MOVEMENT.00:51:24
IT CAN BE SOMETHING, LIKE,
YOU SPAWN OF THE LEVEL,00:51:27
AND IT JUST EXISTS THERE,00:51:29
AND ONCE ANOTHER ACTOR
COLLIDES WITH IT,00:51:31
COLLIDES WITH THE
COLLISION SPHERE,00:51:36
THEN YOU CAN APPLY
A DAMAGE EFFECT00:51:40
TO WHATEVER ACTOR
THAT COLLIDED TO.00:51:42
IT IS NOT THAT VERY DIFFERENT
FROM THE FIREBALL,00:51:47
BUT IT IS JUST NOT SOMETHING
THAT NEEDS TO HAVE A VELOCITY,00:51:51
IT IS GOING TO BE SOMETHING THAT
IS GOING TO BE AT THE LEVEL,00:51:54
WAITING FOR SOMEONE TO HIT IT,
BEFORE APPLYING THE DAMAGE.00:51:58
OF COURSE, YOU NEED TO MAKE
THE TARGETING SYSTEM,00:52:00
SO IF YOU WANT -- IF YOU WANT,
LIKE SAM WAS EXPLAINING,00:52:04
IF YOU WANT TO ACTUALLY POSITION
THIS MINE KIND OF OBJECT,00:52:10
IN SPECIFIC PLACES ON THE LEVEL,00:52:12
YOU NEED TO COME UP
WITH YOUR OWN TARGETING SYSTEM.00:52:15
AND THAT NEEDS A LITTLE BIT
OF YOUR OWN CODE,00:52:18
BUT THAT IS TOTALLY DOABLE.00:52:21
>>SAM: I CAN SEE YOU DOING00:52:23
THE TARGETING SYSTEM
INSIDE OF BLUEPRINT.00:52:26
I DON'T THINK YOU NEED TO GO
OUTSIDE AND DO IT IN C++.00:52:28
>>PAULO: NO.00:52:30
>>SAM: YOU
NEED TO GET YOUR00:52:31
SCREEN COORDINATES
INTO WORLD SPACE.00:52:34
THAT'S THE MOST COMPLICATED PART
OF THAT SET-UP,00:52:38
GOING FROM THE 2D SCREEN
TO MY 3D WORLD.00:52:43
>>PAULO: UNREAL ENGINE HAS SOME NICE
FUNCTIONS FOR THAT KIND OF STUFF,00:52:50
STUFF THAT PRE-DATES
-- THAT COMES00:52:52
FROM GEARS OF WAR,
THINGS LIKE --00:52:55
YOU TRY TO FIND OUT WHAT IS
GOING TO BE THE TRAJECTORY00:53:01
OF A GRENDADE THAT I'M THROWING,
ON UNREAL 4,00:53:05
YOU SHOULD HAVE SOME OF THAT,00:53:07
OR YOU CAN PICK UP
SOME OF YOUR OWN00:53:10
TARGETING SYSTEM FOR A GRENADE
OR MINE PLACEMENT.00:53:15
>>VICTOR:
THERE'S THE SUGGEST00:53:17
PROJECTILE VELOCITY FUNCTION.00:53:19
>>PAULO: YES, I USED THAT A
LOT. IMAGINE WHERE IT CAME FROM,00:53:23
IT CAME FROM QUITE
A FEW YEARS AGO, HAHA.00:53:27
>>VICTOR: YEAH, IT IS GREAT
FOR THINGS LIKE TELEPORT TRACE00:53:29
OR WHENEVER YOU NEED AN ARC.00:53:32
LET'S SEE HERE, THIS ONE --
OVER MY HEAD,00:53:36
BE WE WILL SEE IF YOU CAN ANSWER
IT. ATTRIBUTE CALCULATION FLAW,00:53:40
IT IS NOT CLEAR FROM SOURCE CODE
THE ORDER, CONDITIONS,00:53:43
AND PARAMETERS OF EVENTS
LIKE PRE-ATTRIBUTE CHANGE,00:53:48
PULLS GAMEPLAY EFFECT
EXECUTE, AND SO ON.00:53:53
>>SAM: THAT IS, UH,
THAT IS A BEN ZIEGLER QUESTION.00:53:56
I'M SORRY, I DON'T KNOW
THE ANSWER TO THAT ONE.00:53:59
WE CAN DEFINITELY CONTACT BEN
AND GET DIRECT ANSWER TO THAT.00:54:04
BUT THAT IS -- I DID NOT DO
ANY OF THE C++ CODE.00:54:08
AND PAULO, DO YOU HAVE ANY IDEA?00:54:12
>>PAULO: UH, I HAVE SOME
IDEA ABOUT THE IMPORTANCE OF IT.00:54:15
I CAN UNDERSTAND WHAT
THE PERSON IS LOOKING AT.00:54:18
WE WOULD DEFINITELY NEED TO TALK
TO ONE OF OUR ENGINEERS,00:54:20
BECAUSE THEY UNDERSTAND
THE UNDERLYING CODE,00:54:27
TO GIVE US THAT ANSWER.00:54:29
>>VICTOR: YEAH, WE
WILL REACH OUT AFTERWARD00:54:30
AND POST IT ON THE FORUM
IN CASE WE GET AN ANSWER.00:54:35
SO THERE WAS ANOTHER QUESTION
THAT IS A LITTLE BIT GENERIC,00:54:38
BUT I THOUGHT WAS GOOD
TO MENTION, CAN WE USE00:54:41
THE ASSETS IN THIS EXAMPLE IN A
COMMERCIAL GAME? YES.00:54:44
>>SAM: YES, THIS IS MADE
OF INFINITY BLADE ASSETS,00:54:50
THE SOUL CAVE, THE INFINITY
BLADE CHARACTERS, THE WEAPONS,00:54:55
AND I HAVE GONE THROUGH EVERY
ASSET AND PAINSTAKINGLY MADE00:55:00
SURE WE HAD THE RIGHTS
TO NOT ONLY PUT THIS OUT,00:55:05
BUT THE RIGHTS
TO REDISTRIBUTE IT,00:55:08
BECAUSE WHEN YOU REDISTRIBUTE IT
FOR DOWNLOAD,00:55:12
THIS IS A -- THIS IS A VERY --00:55:16
BECAUSE WE REDISTRIBUTE STUFF,
THAT NULLS A LOT OF LICENSES.00:55:20
A LOT OF THEM SAY, "HEY,
YOU CAN USE THIS FOR FREE00:55:23
IN THE BINARY COMMERCIAL PROJECT
THAT YOU SELL."00:55:25
WE DO NOT SELL BINARIES,
WE SELL --00:55:27
WE DON'T SELL
ANY OF OUR LEARNING STUFF.00:55:30
WHAT WE DO IS WE GIVE YOU STUFF
THAT YOU CAN THEN USE,00:55:33
THAT COUNTS
AS REDISTRIBUTING IT,00:55:35
AND A LOT OF FREE LICENSES
STRICTLY FORBID THAT.00:55:40
ALL OF THE CONTENT
IN THIS PROJECT CAN 100 PERCENT00:55:44
BE USED IN ANY OTHER PROJECT,
OR IF YOU REALLY WANTED TO,00:55:47
YOU COULD MAKE THIS
A LITTLE BIT DIFFERENT00:55:50
AND ACTUALLY PUT THIS UP
ON GOOGLE PLAY.00:55:53
THAT'S NOT TO SAY THAT THEIR ARE
AUTOMATIC STUFF00:55:55
THAT WILL TAKE IT DOWN
FOR YOU, I HAD THAT00:55:58
HAPPEN WHEN I HOSTED
THIS THE WRONG WAY,00:56:00
I PUT IT INTO A DIFFERENT
ACCOUNT AND THEY SAID,00:56:02
"OH, YOU ARE TRYING TO
TAKE EPIC GAME'S ACCOUNT."00:56:05
NO, I DIDN'T DO THAT,
IT WAS A MISTAKE,00:56:07
I WAS ON THE WRONG ACCOUNT AND
POSTED IT TO THE WRONG THING.00:56:12
BUT I HAVE SEEN SOME PEOPLE,00:56:14
ONE OTHER VERSION
OF THIS GAME RELEASED,00:56:16
AND I CAN'T REMEMBER,
THE NAME WAS REALLY CRAZY.00:56:20
IT WAS THE EXACT SAME VERSION
OF THE GAME,00:56:22
SOMEBODY RELEASED IT
TO THE STORE,00:56:24
WHICH YOU ARE MORE
THAN WELCOME TO DO,00:56:27
BUT IT IS FREE FOR YOU TO USE
HOWEVER YOU USE IN THE PROJECT.00:56:34
>>VICTOR: AND THE SAME GOES
FOR EVERYTHING IN THE LEARN TAB.00:56:36
>>SAM: YES, EVERYTHING
IN THE LEARN TAB.00:56:40
>>AMANDA: ANY PLANS TO MAKE
THE GAMEPLAY SYSTEM00:56:43
TO BE BLUEPRINT SET-UP,
OR WILL IT ALWAYS REQUIRE A C++?00:56:48
>>SAM: YES, IT IS ALWAYS
GOING TO REQUIRE C++.00:56:51
THE REASON IS BECAUSE THERE WERE
SOME VERY COMPLEX DAMAGE00:56:54
CALCULATIONS THAT TAKE PLACE
BEHIND THE SCENES,00:56:57
THIS IS ANOTHER GREAT THING
THIS PROJECT IS GREAT FOR,00:57:00
IF YOU EVER WONDER ABOUT
BLUEPRINT AND C++ PARITY,00:57:03
OR YOU DON'T UNDERSTAND
WHAT THAT MEANS,00:57:06
BASICALLY WHAT THAT MEANS,
ALL OF THE COMPLEX STUFF,00:57:10
THE DAMAGE CALCULATIONS,00:57:11
THE HANDLING THE INVENTORY
AND THE UI,00:57:14
ALL OF THE STUFF THAT REQUIRES
SOME HEAVY LIFTING IN C++,00:57:18
IS ALL DONE IN C++.00:57:20
THEN WHAT BEN DID FOR US IS
HE EXPOSED CERTAIN THINGS LIKE,00:57:23
LET ME GO AHEAD
AND OPEN UP -- PICK UP,00:57:30
BECAUSE THAT HAS
SOME STUFF IN IT,00:57:32
I THINK THIS RIGHT HERE, YEA,
SET SLOTTED ITEM.00:57:36
I WILL NOT DOUBLE CLICK ON IT
AND MAKE RPG --00:57:42
MAKE RPG ITEM SLOT,00:57:43
THESE TWO NODES,
IF I DOUBLE CLICK ON THEM,00:57:45
THEY OPEN UP THE SOURCE CODE
INSIDE OF THE C++.00:57:50
INSTEAD OF HAVING EVERYTHING
HARD CODED,00:57:56
YOU HAVE A MAP, A POTION,
A PRIMARY ASSET,00:58:00
A SKILL, A TOKEN, OR A WEAPON.
I, AS ONE OF THE DESIGNERS,00:58:04
OR PAULO,
AS ONE OF THE DESIGNERS,00:58:06
CAN USE NODES TO BUILD THINGS
THAT WERE NOT DESIGNED AT ALL.00:58:10
LIKE THIS PICK UP IS NOT
SOMETHING THAT WE DESIGNED,00:58:13
I JUST WAS LIKE, "I WONDER
IF I CAN MAKE A PICK UP"00:58:15
BECAUSE I HAVE THE ABILITY
TO SET THE SLOTTED ITEM00:58:18
AND UPDATE THE ICON.00:58:19
SO I WONDER IF I CAN DO THIS?00:58:22
IT TOOK ME A DAY
TO GET EVERYTHING WORKING,00:58:25
THE HARD PART WAS GETTING THE
STUPID THE ICON TO CHANGE,00:58:27
I COULD NOT GET IT DONE
FOR THE LONGEST TIME.00:58:31
IT WORKED, THOUGH,00:58:35
AND I WAS SURPRISED HOW FAST
I WAS ABLE TO GET IT TO WORK,00:58:41
BECAUSE ALL OF THIS STUFF
HAS BEEN EXPOSED.00:58:44
IT ALLOWED ME TO DO STUFF
AND EXPERIMENT IN WAYS00:58:47
I WOULD NOT BE ABLE TO DO.00:58:50
PAULO, DO YOU HAVE ANYTHING
TO ADD TO THAT AS WELL?00:58:52
>>PAULO: A
GREAT EXAMPLE OF00:58:54
THAT, IF YOU LOOK
AT THE ABILITIES,00:58:56
LET'S SAY THAT A MELEE BASED
ABILITY00:58:59
THAT WE USE FOR THE SWORDS
AND THE AXES AND ANYTHING.00:59:03
YOU SEE THAT WE HAVE A C++,
AND THAT WILL BE A NODE,00:59:08
A BLUEPRINT NODE,
THAT WAS EXPOSED TO C++,00:59:11
THAT IS CALLED PLAY MONTAGE
AND WAIT FOR EVENT.00:59:13
THIS IS SOMETHING
THAT WAS ACTUALLY CUSTOM00:59:16
BUILT BY BEN ZEIGLER,
THE PROGRAMMER --00:59:22
THE C++ PROGRAMMER
IN THIS PROJECT.00:59:24
BECAUSE THE ORIGINAL DESIGN
FOR THAT WAS THAT WE USED --00:59:29
WELL, A SKILL, OR SOME SORT
OF ATTACK IS LITERALLY A MONTAGE00:59:34
AND, AT A CERTAIN POINT
IN THE ANIMATION,00:59:37
HAVE IT DO A THING
AND RUN THIS BLUEPRINT CODE.00:59:40
WHAT BEN DID FOR US,
HE IMPORTED THAT,00:59:43
AND HE MOVED THAT INTO C++ CODE00:59:45
AND, USUALLY PEOPLE THINK
THAT WE MOVE STUFF,00:59:50
WE MOVE LOGIC TO C++ TO CODE,
BECAUSE OF PERFORMANCE ISSUES,00:59:56
BUT THIS IS ACTUALLY A VERY
GOOD CASE FOR DEBUGGING01:00:00
AND FOR PROJECT MANAGEMENT
REASONS, IT MAKES A LOT OF SENSE01:00:05
TO MOVE SOME OF THE LOGIC
TO CODE, TO C++.01:00:09
SO IT MAKES IT EASIER
FOR PROGRAMMERS01:00:11
TO MAINTAIN AND DEBUG
IN THE LONG-RUN.01:00:15
ANOTHER GREAT EXAMPLE OF THAT
IS THE INVENTORY SYSTEM.01:00:18
I DESIGNED THE INVENTORY SYSTEM
ENTIRELY USING BLUEPRINTS,01:00:22
SO THIS INVENTORY SYSTEM
THAT WE HAVE IN THE GAME NOW,01:00:25
I DESIGNED IT,
IT WAS 100 PERCENT BLUEPRINT.01:00:27
BUT BEN MADE THE DECISION,
AND I AGREE,01:00:30
THAT YEAH, WE SHOULD
DEFINITELY MOVE THIS TO C++01:00:33
BECAUSE THIS IS THE EXACT KIND
OF THING THAT A PROGRAMMER --01:00:39
WILL WANT TO MOVE TO C++,01:00:40
BECAUSE IT IS A LITTLE BIT
MORE MANAGEABLE WHEN YOU ARE --01:00:44
FOR A PROJECT
THE SIZE OF ACTION RPG,01:00:46
THAT IS 100 PERCENT OKAY
TO GET THAT AS A BLUEPRINT.01:00:49
AS YOU MOVE INTO THE TERRITORY
OF MORE COMPLEX PROBLEMS,01:00:53
WHEN WE ARE TALKING ABOUT GAMES,
LIKE WHAT WE DO,01:00:55
LIKE FORTNITE AND PARAGON,01:00:57
IT MAKES IT EASIER IN THE LONG
RUN AS THE PROJECT GROWS01:01:00
TO HAVE THIS SORT OF KEY
FUNCTIONALITY IN CODE IN C++,01:01:05
BECAUSE IT MAKES IT EASIER01:01:07
TO MAINTAIN AND DEVELOP
IN THE LONG TERM.01:01:12
>>SAM: SO ONE THING I WANT
TO ADD TO THAT,01:01:14
IF WE KICK IT OVER TO THE SCREEN
REAL QUICK, THIS --01:01:17
SO I WILL ZOOM IN A LITTLE HERE.01:01:20
BUT BASICALLY,
SO THIS IS THE SWORD --01:01:22
AND I ONLY AM SHOWING YOU
ONE COMBO RIGHT HERE.01:01:26
BUT ALL OF THESE
LITTLE SECTIONS IN HERE,01:01:29
THIS IS HOW
WE ARE TRIGGERING THINGS.01:01:31
YOU CAN SEE THIS WEAPON ATTACK,01:01:33
THIS
IS GOING TO BE DOING THE DAMAGE.01:01:35
AND ONE OF THESE STOPS US,
ONE OF THESE MAKES US IMMUNE,01:01:41
THIS WILL BLOCK
ANY INCOMING ITEM.01:01:45
>>PAULO: WEAPON ATTACK IS
THE ONE THAT ACTUALLY DOES --01:01:49
IT RUNS THE ATTACK CODE.01:01:50
>>SAM: YEAH, THIS
ONE -- SO THIS RUNS IT.01:01:52
AND YOU COME IN HERE AND YOU ADD
A NOTIFY, YOU CAN SEE THAT --01:01:55
OR I CAN ADD A STATE NOTIFY.01:01:57
AND THE STATE NOTIFY --
THE STATES ARE DOING THE TRAILS,01:02:01
WHEN HE GOES INTO SLOW MOTION,
WHEN HE IS DOING A KICK,01:02:04
WE CALL THE SLOW MOTION
NOTIFIER RIGHT HERE.01:02:06
AND, BY COMBINING
ALL OF THESE THINGS TOGETHER,01:02:09
AND AGAIN, THIS IS WHY
I DIDN'T SET UP A DOCUMENT01:02:12
ABOUT DEVELOPING A NEW SKILL,
BECAUSE THERE IS --01:02:17
THERE IS SO MUCH COMPLEXITY
TO WHAT WE CURRENTLY HAVE01:02:21
THAT ADDING A NEW ONE,
IT IS JUST -- THERE'S --01:02:25
THERE ARE TOO MANY VARIABLES,
TOO MANY KNOBS,01:02:27
YOU ARE GOING TO HAVE
TO FILL IN AND TURN.01:02:30
AND ALSO, WE DIDN'T KNOW
EXACTLY WHAT OTHER SKILLS01:02:33
THAT WE WANTED TO ADD
TO THIS PARTICULAR PROJECT.01:02:35
WE DIDN'T KNOW IF, YOU KNOW,
IF WE WANTED TO ADD,01:02:39
YOU KNOW, A BOW AND ARROW,
OR SOMETHING LIKE THAT.01:02:43
BUT, WITH THAT SAID, IT IS EASY
FOR YOU TO COME IN HERE01:02:46
AND SAY YOU REALLY LIKE THIS --01:02:48
BUT YOU DON'T WANT THE TRAILS;
IF I CAN FIND THEM.01:02:52
I SAY THIS NOW,
BECAUSE I FOUND THESE EARLIER,01:02:54
BUT NOW I DON'T REMEMBER
WHERE THEY ARE.01:02:56
YOU CAN ACTUALLY JUST DISABLE
THEM FROM HERE, AND I THINK --01:03:00
OH, HERE THEY ARE.
YEAH, THERE'S ONE, AND SO -- OH.01:03:04
THERE'S THE SHIELD
I MENTIONED --01:03:05
THIS WILL INVOKE A SHIELD
ON THE PLAYER01:03:08
SO THEY ARE NOT DAMAGED
BY THEIR OWN ATTACK,01:03:12
OR SOMETHING LIKE THAT.01:03:13
AND LET'S SEE, WHAT ELSE.01:03:18
THAT IS PRETTY MUCH IT.01:03:19
IF I WANTED
TO GET RID OF THE TRAILS,01:03:21
I WOULD DELETE THIS
NOTIFY HERE.01:03:23
I DON'T WANT TO DO THAT BECAUSE
I'M NOT SURE IF I DELETE THAT,01:03:26
IF IT WILL CRASH OR NOT.
BECAUSE IT IS STILL PLAYING.01:03:29
>> [ LAUGHTER ].01:03:30
>>SAM: I DON'T WANT TO
OPEN EVERYTHING BACK UP AGAIN.01:03:35
BUT, YEAH, THIS --01:03:39
THIS LOOKS SUPER COMPLICATED,
AND I CAN GO TO ANOTHER --01:03:42
BUT THIS IS THE BREAD AND BUTTER
OF ALL OF THE ABILITIES,01:03:45
EVERYTHING THAT HAS --
AS WE MENTIONED BEFORE,01:03:47
EVERYTHING WAS BUILT
BEFORE USING THE MONTAGE,01:03:50
THIS IS HOW
IT IS SET UP AND DONE.01:03:53
THE DAMAGE CODE RUNS,01:03:55
IT IS WHERE WE MAKE SURE
THE PLAYER CANNOT BE DAMAGED,01:03:57
IT HAS A SHIELD, AND IT IS
ALSO STANDARD ANIMATION NOTIFY.01:04:03
IT IS NOT SOMETHING
THAT IS NEW, OR UNIQUE,01:04:05
THIS IS JUST HOW YOU USE
THE ANIM NOTIFY SYSTEM01:04:08
WITHIN THE ANIMATION MONTAGES.01:04:10
SO YOU WILL FIND IT USED
IN A LOT OF VIDEO GAMES.01:04:13
A LOT OF PEOPLE USE THE NOTIFY
TO DO FOOT STEPS, SOUNDS,01:04:17
OR PROTOCOLS THAT COME UP
FOR DUST PARTICLES OR SOMETHING,01:04:21
THOSE ARE THE COMMON USES FOR
THIS,01:04:23
BUT IT DOESN'T MEAN YOU HAVE
TO USE IT SPECIFICALLY FOR THAT.01:04:28
>>PAULO: YEAH, THAT WAS --
SORRY.01:04:31
THAT WAS WHAT
I WAS GOING TO SAY.01:04:35
THAT'S WHY SOME OF THIS
STUFF IS IN C++,01:04:38
IT IS CUSTOMIZED
TO THE USES01:04:42
THAT WE DID FOR THE PROJECT.01:04:44
I'M NOT SAYING YOU HAVE TO USE
THE MONTAGES FOR THE GAME,01:04:47
OR THE ABILITY SYSTEM,
IN ACTION RPG,01:04:53
WE HAD TO USE BOTH01:04:55
AND THAT'S WHY
OUR IMPLEMENTATION IS SO CUSTOM,01:04:59
AND BECAUSE GAMES ARE VERY, VERY
DIFFERENT FROM EACH OTHER,01:05:06
THAT IS PROBABLY WHY --
WE'RE NOT SURE YET.01:05:08
MAYBE -- THAT IS SOMETHING
THAT MAY CHANGE IN THE FUTURE,01:05:11
THAT IS PROBABLY
ONE OF THE REASONS01:05:13
WHY THE ABILITY SYSTEM
THAT IS SO COMPLEX,01:05:16
IS GOING TO BE KEPT FOR A
WHILE, UNDER C++ CONTROL.01:05:21
I BELIEVE THOSE ARE
ONE OF THE REASONS FOR THAT.01:05:27
>>AMANDA: JUST COMMENTING --
LOOPING BACK AROUND.01:05:30
THE DOCS ACTUALLY DO
A PRETTY GOOD JOB01:05:32
OF EXPLAINING THE C++ VERSION.01:05:34
>>SAM: YES, LET ME PULL THIS
BACK OVER HERE --01:05:36
>>AMANDA: -- OF
USAGE IN THE SYSTEM.01:05:38
>>SAM: WE HAVE THE BUILDING C++ --
THIS IS GOING TO BREAK DOWN01:05:43
BASICALLY
WHAT THE CODE OVERVIEW IS.01:05:46
IT GOES OVER ALL
OF THE HEADER FILES,01:05:50
WHICH YOU CAN FIND
IN EACH OF THE H FILES,01:05:53
IT TALKS ABOUT OUR INVENTORY
AND ASSET MANAGEMENT.01:05:56
WE GET A DESCRIPTION
OF WHAT WEAPONS,01:05:58
SKILLS, POTIONS, AND TOKENS ARE.01:06:01
AND THIS IS TEXT OVERLOAD,
WHAT AM I GOING TO DO,01:06:04
AND THIS DOCUMENT
AND THIS DOCUMENT01:06:08
AND THIS DOCUMENT ARE ALL AIMED
AT C++ PROGRAMMERS.01:06:14
SO IF YOU ARE AN ARTIST,
OR A DESIGNER, BY ALL MEANS,01:06:17
HAVE A LOOK AT THIS.01:06:19
DON'T FEEL BAD
IF IT JUST GOES OVER YOUR HEAD.01:06:21
THERE IS NOT A LOT IN HERE01:06:22
THAT YOU REALLY NEED
TO BE CONCERNED WITH.01:06:26
WE DO HAVE A BREAKDOWN BASICALLY
OF EVERYTHING01:06:28
THAT WE KIND OF EXPLAINED TODAY
-- IS DOCUMENTED IN THESE.01:06:31
SO ATTRIBUTES AND EFFECTS,
MELEE ABILITIES,01:06:34
SKILL ABILITIES,
AND EXECUTING ABILITIES.01:06:37
EACH ONE OF THESE DOCUMENTS
IS GOING TO BREAK DOWN,01:06:40
AT A VERY HIGH AND LOW LEVEL,
EXACTLY WHAT THIS PART DOES01:06:44
AND THESE WERE ACTUALLY WRITTEN
BY BEN ZEIGLER HIMSELF,01:06:46
WHO WROTE THE SYSTEM,
I DID THE COPY,01:06:48
MADE SURE IT DOESN'T SAY
ANYTHING TOO CRAZY,01:06:51
OR DID NOT TRANSLATE WELL
INTO OTHER LANGUAGES.01:06:55
BUT THIS IS EXACTLY
WHAT HE SAID ABOUT THE SYSTEM.01:07:00
IF YOU WANT MORE
IN-DEPTH INFORMATION01:07:02
THAN WE ARE PROVIDING TODAY,01:07:04
THESE ARE THE DOCS
YOU WANT TO LOOK AT.01:07:06
>>VICTOR: YOU DID MENTION
EARLIER, IN TALKING LAST WEEK,01:07:08
THERE WAS AN UPDATE COMING
TO THE DOCUMENTATION AS WELL.01:07:12
>>SAM: YES, THOSE ARE
THESE GUIDES RIGHT HERE,01:07:14
WE DIDN'T HAVE THEM
BEFORE T THEY ARE BRAND NEW.01:07:15
SO ADDING A RANDOM SOUL,01:07:17
A NEW PICK UP
AND ADDING A NEW POTION.01:07:22
THESE ARE NEW DOCS,
I WROTE THEM A MONTH AGO01:07:27
AROUND CHRISTMAS TIME AND
JUST GOT THEM INTO THE CMS.01:07:35
I WANTED DOCS FOR
ARTISTS AND DESIGNERS,01:07:38
WHILE YOU CAN GET A LOT OF
INFORMATION FROM THE DOCS ABOVE,01:07:41
IF YOU DIDN'T HAVE
ANY BLUEPRINT KNOWLEDGE01:07:44
OR C++ KNOWLEDGE
OR LIMITED BLUEPRINT KNOWLEDGE,01:07:46
YOU WOULDN'T REALLY GET OUT
OF THEM WHAT YOU NEEDED TO GET.01:07:49
SO I WANTED TO GIVE PEOPLE
THAT DON'T COME FROM A CODING01:07:53
BACKGROUND, LIKE MYSELF,
SOMETHING THAT THEY COULD,01:07:55
YOU KNOW, START SMALL
AND KIND OF WORK UP TO.01:07:59
YOU KNOW, IF I WAS DOING THIS
AND LOOKING TO START, YOU KNOW,01:08:02
SOMETHING BRAND NEW,
I WOULD DO --01:08:04
AGAIN, I WOULD DO
THE POTION DOCUMENT FIRST,01:08:07
FOLLOWED BY THE WEAPON DOCUMENT,
AND THEN ADDING A RANDOM SOUL,01:08:12
AND THIS ACTUALLY HAS LESS STEPS
THAN THIS, ADDING A PICK UP.01:08:16
ADDING A PICK UP IS A LITTLE
MORE COMPLICATED.01:08:18
THIS ONE AND ADDING A WEAPON,01:08:23
THAT IS ACTUALLY
ONE OF MY FAVORITE ONES01:08:24
BECAUSE WHAT THIS WILL
ALLOW YOU TO DO,01:08:26
SAY YOU CREATE A WEAPON IN MAYA,
EXPORT IT AS A SKELETAL MESH,01:08:32
SLOT IT IN THERE,
AND YOU HAVE A WEAPON.01:08:34
IT IS THAT QUICK TO GET IT
IN YOUR PLAYER'S HANDS01:08:38
AND SEE IT USED.01:08:41
THESE DOCUMENTS ARE AIMED FOR
A QUICK PATH TO SUCCESS.01:08:46
IT SHOULD TAKE YOU 30
TO 40 MINUTES TO GO THROUGH IT01:08:49
AND GET IT WORKING.01:08:51
AND ONE OTHER THING
I WANT TO POINT OUT,01:08:54
ALL OF THESE DOCUMENTS,01:08:55
AND YOU SEE EVERYTHING
EXISTS INSIDE OF THE GAME,01:08:59
IF YOU ARE FOLLOWING ALONG
WITH THESE,01:09:01
YOU ARE GOING TO WANT TO MODIFY
THE NAME A LITTLE BIT TO ENSURE01:09:04
IT IS DIFFERENT THAT
WHAT EXISTS IN THERE OR01:09:08
YOU ARE GOING TO GET
A NAMING CONFLICT.01:09:10
I DID IT SO YOU HAVE
THE FINAL RESULT,01:09:13
IT SUCKS WHEN YOU ARE
BUILDING SOMETHING,01:09:16
YOU ARE FOLLOWING A TUTORIAL01:09:17
AND YOU DON'T NECESSARILY
UNDERSTAND EVERYTHING01:09:20
AND YOU HAVE NOTHING TO LOOK AT,
WHERE DID I GO WRONG,01:09:24
WHAT DID I FORGET IN01:09:26
MY VERSION, VERSUS
WHAT THEY HAD.01:09:28
SO I WANTED TO GIVE EVERYBODY
A VERSION OF THIS01:09:31
THAT WAS COMPLETELY DONE01:09:32
SO YOU HAVE SOMETHING
TO LOOK AT TO KIND OF, YOU KNOW,01:09:36
GIVE A LITTLE BIT OF GUIDANCE
IN CASE YOU ARE WONDERING01:09:38
WHERE YOU WENT WRONG
OR SOMETHING LIKE THAT.01:09:41
>>VICTOR: WHEN WILL
THEY SEE THE UPDATED PROJECT?01:09:45
>>SAM: THIS WILL GO OUT
IN 4.22.01:09:47
SO I WILL UPDATE IT
ON ALL OF THE STORES,01:09:49
I WILL PUSH THAT OUT SOMETIME
HOPEFULLY BEFORE GDC, YEAH.01:09:55
RELEASED --
>>PAULO YES.01:09:57
>>SAM: YEAH, YEAH.01:09:58
THIS ALREADY GOT PUSHED UP
TO THE RELEASE BRANCH,01:10:01
IT IS IN THERE ALREADY01:10:03
WITH EVERYTHING
THAT YOU SEE HERE TODAY,01:10:06
AND EVERYTHING THAT IS HERE IS
IN THE 4.22 RELEASE BRANCH,01:10:10
I SYNCED IT, CHECKED IT OUT.
YOU WILL SEE IT01:10:14
IN THE NEXT UPDATE
UNLESS SOMETHING HAPPENS.01:10:17
>>VICTOR: THAT'S GREAT.01:10:20
IN TERMS OF TRACKING
VERSION CHANGES,01:10:22
EACH TIME EPIC UPDATES
THE ACTION RPG SAMPLE,01:10:24
IS THERE A VERSION NUMBER
IN THE PROJECT01:10:27
FOR SOMEBODY WHO MIGHT HAVE
SEVERAL COPIES OF IT?01:10:30
>>PAULO: THAT'S A GOOD
QUESTION.01:10:32
>>SAM: YOU CAN HOVER OVER
HERE01:10:34
ON THE TOP
OF ANY UNREAL EDITOR PROJECT01:10:39
AND YOU WILL SEE
WHAT VERSION YOU ARE,01:10:41
YOU WILL SEE IF THIS IS UE4
DEV DOCUMENTATION,01:10:43
AND IT WAS BUILT ON JANUARY 24,
WITH VERSION 4.22.0,01:10:51
I'M NOT SURE WHAT THE REST
OF THE NUMBERS MEAN.01:10:53
I HAD A SCALE
THAT I PULLED IT FROM.01:10:56
>>PAULO: I THINK THEY ARE
ASKING01:11:00
ABOUT THE PROJECT ITSELF,
VERSION NUMBERS,01:11:04
SO THEY PROBABLY
HAVE AN EASIER --01:11:06
THEY MAKE IT EASIER
WHEN THEY WANT TO --01:11:08
YOU KNOW, EVEN THOUGH
WE RECOMMENDED01:11:11
THAT YOU DON'T DO THIS,
PEOPLE STILL WANT TO DO THIS.01:11:15
THEY STILL WANT TO, LIKE,
UPDATE THEIR OWN PROJECTS01:11:17
BY SYNCING BACK THEIR STUFF
FROM ACTION RPG.01:11:21
I'M NOT SURE WE SUPPORT THAT.01:11:24
>>SAM: YOU'RE -- YOU WILL
HAVE A BAD TIME.01:11:26
>>PAULO: YES.01:11:27
>>SAM: WE DIDN'T BUILD THE GAME
WITH THAT IN MIND BECAUSE,01:11:31
SO THE OTHER THING, THIS IS
BUILT LIKE AN ACTUAL GAME.01:11:34
IT CAME FROM A PROTOTYPE
THAT SOMEBODY MADE THAT WE TOOK,01:11:38
BECAUSE IT WAS BUILT
IN BLUEPRINT ORIGINALLY.01:11:40
WE TOOK A PROJECT,
A PROTOTYPE PROJECT,01:11:44
WE REMOVED THE EXPENSIVE
CALCULATIONS FROM BLUEPRINT,01:11:47
PUT THEM INTO C++
AND WE ARE ITERATING ON THIS01:11:50
AS YOU WOULD WITH
A REAL PROJECT.01:11:52
THIS IS AS CLOSE AS YOU
ARE GOING TO GET INTO01:11:55
SOMEBODY'S DEVELOPMENT
AT A PROFESSIONAL STUDIO --01:11:58
OTHER THAN WORKING
AT A PROFESSIONAL STUDIO01:12:00
ON A VIDEO GAME.
IT MAY BE A SMALL PROJECT,01:12:05
BUT THIS IS TOTALLY SOMETHING
THAT A TWO-MAN TEAM CAN MAKE.01:12:09
ONE OF THE CORE TENEMENTS
OF DEVELOPMENT,01:12:14
WHEN YOU ARE IN PRODUCTION,
YOU DO NOT UPDATE YOUR CODE BASE01:12:17
UNLESS YOU NEED
SOMETHING THAT,01:12:19
MEANS SOMETHING
THAT YOUR GAME CAN'T SHIP.01:12:21
SAY THERE'S AN UPDATE
TO ANDROID OR IOS,01:12:25
THAT YOU HAVE TO
TAKE THIS UPDATE01:12:27
OR YOU CANNOT PACKAGE THE GAME
FOR THE STORE,01:12:29
THAT'S THE ONLY TIME YOU TAKE
ANOTHER VERSION OF THE ENGINE,01:12:33
AND EVEN THEN, YOU ONLY TAKE
A SPECIFIC CHANGE LIST01:12:37
OR MULTIPLE CHANGE LISTS TO GIVE
THAT SPECIFIC FUNCTIONALITY.01:12:41
I HAVE NEVER WORKED
IN A STUDIO01:12:42
EVER THAT MADE IT HALFWAY
THROUGH PRODUCTION01:12:45
AND SAID, YOU KNOW WHAT, WE WILL
TAKE THE LATEST AND GREATEST01:12:49
BECAUSE WE HAVE
SOME TIME TO KILL01:12:52
AND WE WANT
SOME BUGS TO SQUASH.01:12:56
>>PAULO: SOME STUDIOS DO
THAT.01:12:58
THEY USUALLY --
>>SAM: YES.01:13:00
>>PAULO: THEY USUALLY
NEVER SHIP A GAME.01:13:02
BUT ANYWAY, WHAT I WOULD SAY
IN REGARD TO VERSIONS,01:13:09
WE COULD TELL THAT YOU CAN
TIE ACTION RPG VERSIONS01:13:14
TO ENGINE VERSION.01:13:16
WE HAVE BEEN TRYING
TO RELEASE UPDATES01:13:20
FOR EVERY MAJOR VERSION
OF THE ENGINE.01:13:23
SO ACTION RPG
WAS RELEASED ON 4.20.01:13:27
I THINK WE SKIPPED 4.21.01:13:30
>>SAM: WE MADE SOME
UPDATES TO IT, BUT NOT A LOT.01:13:33
WITH MAINTENANCE STUFF
AND A LITTLE BIT OF REFACTORING,01:13:36
BUT THERE WERE NOT
MASSIVE CHANGES TO IT.01:13:39
4.22, THOUGH.01:13:41
>>PAULO: YEAH, 4.22,
IT IS A DIFFERENT STORY,01:13:43
WITH A BUNCH OF CHANGES TO IT.01:13:46
SO, YES, I WOULD TIE IT
TO EVERY MAJOR ENGINE RELEASE,01:13:51
IF YOU WANT TO SAY
THAT ACTION RPG 4.20,01:13:54
ACTION RPG 4.21,
ACTION RPG 4.22...01:14:00
JUST REINFORCING
WHAT SAM WAS SAYING,01:14:05
THERE IS ONE THING YOU
FIND OUT WITH GAME DEVELOPMENT01:14:07
IS WE HAVE BEEN TRYING
TO BUILD ACTION RPG01:14:10
AND THE WAY THAT IS THE
MOST PROFESSIONAL POSSIBLE,01:14:14
OR THE CLOSEST TO WHAT WOULD BE01:14:17
BEST PRACTICES IN
GAME DEVELOPMENT.01:14:21
THE THING IS,
WHEN YOU TRY TO MAKE A GAME01:14:25
THAT IS NOT ONLY GOING TO BE
A SAMPLE PROJECT,01:14:28
OR AN EXAMPLE, YOU ARE
TRYING TO SHIP SOMETHING.01:14:33
SOMETIMES YOU HAVE TO --
YOU HAVE TO ALLOW SOME --01:14:37
SOME THINGS THAT ARE NOT
NECESSARILY BEST PRACTICE,01:14:41
BUT ARE THERE TO MAKE THE GAME
--01:14:45
SO THE GAME
IS ACTUALLY SHIPPABLE,01:14:47
SO WE CAN GO TO THE STORE,
SO WE CAN FIX A BUG,01:14:51
AND USUALLY -- IT IS NOT GOING
TO BE LIKE THE MOST --01:14:54
THE BEST WAY TO FIX SOMETHING,
BUT IT IS THE WAY THAT WE FOUND01:14:58
AT THAT MOMENT
WE HAD TO USE IT,01:15:00
BECAUSE WE DIDN'T HAVE TIME.01:15:02
AND THESE ARE THE TARGETS,01:15:03
AND THESE ARE THE KIND OF THINGS
THAT WE WANT TO CHANGE01:15:06
WITH ACTION RPG,
THAT KIND OF STUFF.01:15:07
IT IS NOT NECESSARILY
BEST PRACTICE,01:15:09
BUT IT IS THERE
JUST BECAUSE WE CAN SHIP IT.01:15:12
THIS IS -- THIS IS THE EXACT
KIND OF STUFF01:15:15
THAT WE CHANGE OVER TIME,
TO MAKE THE PROJECT,01:15:20
ALL OF IT SHOWING
THE BEST PRACTICE FOR SOMETHING.01:15:24
AND THOSE ARE THE POINTS01:15:25
WHERE IF YOU TRY TO SYNC
AN OLDER VERSION OF ACTION01:15:29
RPG TO A NEWER VERSION,
IT IS THE --01:15:32
IT IS THE EXACT POINTS THAT YOU
MAY FACE BUGS AND ISSUES01:15:37
THAT YOU HAVE TO FIX YOURSELF.01:15:41
>>SAM: WELL, ONE OF THE ONES
THAT WE FOUND,01:15:45
AND I NEVER TESTED THIS,
BUT YOU COULDN'T --01:15:49
IF YOU DIDN'T HAVE A WEAPON
IN THE FIRST SLOT01:15:51
IN YOUR INVENTORY,01:15:53
AND YOU HAD ONE IN THE SECOND
AND THE THIRD ONE,01:15:55
YOU WEREN'T ABLE TO SELECT
THE WEAPON IN THE FIRST SLOT,01:15:57
BECAUSE THERE WAS A MISMATCH AND
THE ARRAY, THERE WAS A MAP --01:16:01
AND SO BASICALLY THE INVENTORY
WAS LOOKING FOR SLOT TWO,01:16:05
BUT IT COULD ONLY SEE SLOTS
THREE THROUGH FIVE,01:16:08
AND THERE WAS NO SLOT TWO,
IT DIDN'T EXIST.01:16:10
SO WE HAD TO PUT IN A HACK
TO RE-MAP THE INVENTORY01:16:16
SO THAT IT GOT THE RIGHT NUMBER
IN THE ARRAY01:16:18
TO GET IT OUT FOR 4.21.01:16:20
AND THEN WE ACTUALLY REDESIGNED
HOW THAT SYSTEM WORKED,01:16:23
ONCE WE REALIZED
WE HAD A BUG THERE.01:16:25
SO THIS IS EXACTLY
WHAT PAULO WAS SAYING,01:16:27
WE MADE THIS IN THE BEST WAY
THAT WE CAN,01:16:31
BUT SOMEBODY ALWAYS DOES SOMETHING
SOMETHING WE NEVER THINK OF,01:16:35
WE HAVE A BUG
THAT WE NEED TO FIX01:16:38
BECAUSE THIS THING HAPPENED,01:16:40
AND NOW WE HAVE TO SCRAMBLE
TO FIX IT.01:16:42
AND THESE ARE --
THESE ARE JUST --01:16:44
THIS IS HOW GAME DEVELOPMENT IS.01:16:45
>>VICTOR: YEP.01:16:46
>>SAM: THIS IS HOW IT
GOES.01:16:48
>>PAULO: AND
JUST BEFORE I MOVE ON,01:16:50
I THINK THAT YOU ARE GOING
TO HAVE A HARD TIME01:16:54
IF YOU TRY TO SYNC FROM
A NEWER VERSION OF ACTION RPG.01:16:58
WHEN IT COMES UP,
WHEN 4.22 COMES UP --01:17:01
WE CHANGED THE WAY THAT WE DO
THE ON-SCREEN CONTROLS,01:17:08
THE ON-SCREEN PART OF THE GAME,
WE CHANGED ALMOST EVERYTHING.01:17:12
TO ADD SUPPORT FOR THE INTERFACE
THAT SAM SHOWED YOU,01:17:16
YOU HAVE TO DO A LOT OF STUFF,
YOU HAVE A HARD TIME01:17:18
IF YOU WANT TO
SYNC 4.22 TO 4.21.01:17:23
SO A HEADS-UP NOTE
FOR THE ONES THAT ARE --01:17:28
IF YOU WANT TO TRY THIS.01:17:32
>>SAM: YOU ARE GOING
TO HAVE A BAD TIME.01:17:37
>>VICTOR: WOULD
IT BE BETTER TO01:17:39
HAVE INDIVIDUAL
WEAPON-BASED CLASS,01:17:40
RANGE, MELEE, ETC.,01:17:42
OR A SINGLE-BASED CLASS
THAT ALL WEAPONS PULL FROM?01:17:47
>>SAM: SO...01:17:55
THAT'S MORE OF A
PHILOSOPHICAL QUESTION --01:17:57
THAN YOU SHOULD DO IT
THIS WAY OR THE OTHER.01:18:00
THERE ISN'T A -- WHICH EVER WAY
YOU PICK OUT OF THAT ONE01:18:05
ISN'T GOING TO AFFECT
PERFORMANCE OR SOMETHING,01:18:07
IT IS GOING TO AFFECT THE
ABILITY TO UPDATE YOUR PROJECT.01:18:12
I WOULD HAVE ONE
WEAPON-BASED CLASS,01:18:14
THAT MEANS I ONLY HAVE
TO FIX A BUG IN ONE LOCATION01:18:17
AND IT PROPAGATES UP
TO EVERYTHING. IF I HAVE A CLASS01:18:20
FOR MELEE, RANGE AND SPECIAL
WEAPONS,01:18:24
THOSE ARE THREE BASE CLASSES01:18:26
I HAVE TO MAKE SURE
THAT BUGS ARE FIXED01:18:28
IN AND THREE BASE CLASSES
I HAVE TO TEST FOR.01:18:32
SO I PREFER TO JUST
HAVE ONE BASE CLASS.01:18:37
BUT IT IS NOT TO SAY THAT
YOU COULDN'T DO IT THAT WAY.01:18:41
BUT THAT IS MORE
OF A PHILOSOPHICAL01:18:42
KIND OF PROCESS QUESTION THAN A,
WHAT'S THE WORD I'M LOOKING FOR,01:18:48
A REQUIREMENT OF DEVELOPMENT
FOR THIS PROJECT.01:18:53
>>PAULO: MORE IMPORTANTLY
IS YOU TRY TO PLAN AHEAD,01:18:55
TRY TO WRITE DOWN SOME NOTES
OF WHAT KIND OF FEATURES01:19:00
YOUR GAME WILL HAVE,
AND THEN PICK THE RIGHT FACTOR,01:19:04
DEPENDING ON YOUR PLANS
FOR THE GAME, FOR THE FUTURE.01:19:10
>>VICTOR: IS IT
VIABLE TO USE GAMEPLAY01:19:13
EVENT OBJECTS FOR
DAMAGE EXECUTIONS01:19:15
RATHER THAN USING
A DUMMY ATTRIBUTE?01:19:19
>>SAM: THAT I HAVE NO
IDEA.01:19:20
I DID NOT WORK ON
ANY OF THE ATTRIBUTES.01:19:24
PAULO, DO YOU HAPPEN TO KNOW
THE ANSWER TO THIS QUESTION?01:19:27
>>PAULO: GAMEPLAY --
SORRY?01:19:31
>>VICTOR: IS IT VIABLE
TO USE GAMEPLAY EVENT OBJECTS01:19:34
FOR DAMAGE EXECUTIONS01:19:35
RATHER THAN USING
A DUMMY ATTRIBUTE,01:19:37
AND THERE'S A LITTLE NOTE,01:19:39
GIVEN THEIR MAGNITUDE FIELD
AND ABILITY01:19:42
TO ATTACH SECONDARY OBJECTS
FOR INFORMATION?01:19:46
>>PAULO: WOAH, I'M NOT
100 PERCENT SURE.01:19:49
>>VICTOR: WE CAN GET BACK
TO IT.01:19:51
>>PAULO: YES, BUT I THINK IT
IS.01:19:53
AN ABILITY -- FOR ONE TO EXECUTE
AN ABILITY AND, BY THAT,01:19:57
I MEAN FOR AN ACTOR
TO EXECUTE AN ABILITY,01:20:00
YOU BASICALLY JUST NEED TO HAVE
AN ABILITY SYSTEM COMPONENT,01:20:04
AND IT SHOULD BE ABLE TO
EXECUTE -- TRY EXECUTING,01:20:08
THAT SHOULD BE THE RIGHT
WORDING, A SPECIFIC ABILITY01:20:13
AND IT IS
THE DATA ABILITY COMPONENT.01:20:16
IT IS NOT VERY DIFFERENT
FROM THAT.01:20:23
IT SHOULD BE, BUT I'M NOT SURE.01:20:28
>>VICTOR: LET'S SEE,
HOW MUCH TIME HAVE WE GOT --01:20:30
A LITTLE BIT OF TIME
FOR A FEW MORE?01:20:33
>>AMANDA: CAN
YOU HAVE THE ASSETS01:20:34
INTERACT WITH THE
NIAGARA MODULE?01:20:37
>>SAM: PROBABLY,
I HAVEN'T TESTED01:20:40
NIAGARA FOR THIS
PROJECT AT ALL.01:20:43
>>AMANDA: UH-HUH.01:20:44
>>SAM: I AM NOT SURE THAT01:20:46
NIAGARA IN ITS
CURRENT STATE WORKS,01:20:48
IT MIGHT WORK ON MOBILE,01:20:49
BUT I DON'T KNOW IF IT HAS BEEN
BATTLE TESTED OR NOT.01:20:52
SINCE THIS IS
A MOBILE-CENTRIC GAME,01:20:55
WE DID NOT DO ANYTHING
WITH NIAGARA.01:20:56
HOWEVER,
SINCE GOING FROM NIAGARA --01:21:02
ERR, FROM CASCADE TO NIAGARA
IS A BIG THING,01:21:06
ONCE IT IS A BIT MORE MATURE,01:21:08
I WILL DO A GUIDE THAT SHOWS
THE EFFECTS IN THIS GAME AND01:21:11
PORT FROM FROM CASCADE
TO NIAGARA,01:21:14
SO YOU CAN SEE
HOW I WENT FROM ONE TO ANOTHER01:21:19
AND GIVE YOU EXAMPLES AS WELL.01:21:23
THAT WILL COME WHEN NIAGARA
IS MORE FEATURE COMPLETE01:21:26
AND READY FOR MOBILE DEVICES,
I NEED GPU PARTICLES TO WORK01:21:32
AND A LOT OF THINGS
IN THE PLANS TO BE WORKING,01:21:37
BUT NOT QUITE THERE YET.01:21:38
I WILL DEFINITELY
BE TAKING CARE OF THAT.01:21:40
>>AMANDA: PERFECT.01:21:41
>>PAULO: OR BASICALLY,
WHEN IT IS DONE.01:21:44
>>AMANDA: YEAH, HAHA.
>> [ LAUGHTER ].01:21:45
>>VICTOR: IT WILL BE.01:21:47
UM, IS THE VERSION
OF GAMEPLAYABILITY SYSTEM01:21:50
SIMILAR TO THE ONE
USED IN FORTNITE?01:21:56
>>PAULO: THAT'S A GOOD
QUESTION.01:21:58
>>SAM: IT IS A HARD QUESTION
TO ANSWER,01:22:00
BECAUSE ONE, I DON'T KNOW ENOUGH
ABOUT FORTNITE'S ABILITY SYSTEM.01:22:04
I HAVE BEEN TOLD BY LOTS OF01:22:06
PEOPLE IN THE
GAMEPLAY FRAMEWORK,01:22:09
WHAT WE DID IN ACTION RPG
IS BASED OFF OF THE SAME CODE.01:22:13
WHILE IT IS NOT A ONE
TO ONE MATCH,01:22:17
IT IS IN A SIMILAR BALLPARK
TO HOW IT IS ARCHITECTED.01:22:22
I WOULD SAY THAT ARCHITECTURE
IS THE SAME,01:22:24
BUT THE EXECUTION
IS CUSTOM TO US.01:22:28
IF YOU WANTED TO KNOW MORE ABOUT
THE GAMEPLAY ABILITY SYSTEM,01:22:32
AND HOW IT IS BUILT,01:22:33
AND HOW IT IS ARCHITECTURED
TO INCLUDE EVERYTHING,01:22:38
HAVING A LOOK AT THAT WILL
GIVE YOU A GOOD IDEA OF THAT.01:22:41
BUT THERE IS PROBABLY
A LOT OF CUSTOM CODE01:22:43
THAT WAS IN FORTNITE OR PARAGON
THAT WE DON'T HAVE.01:22:48
BEFORE WHEN
I WAS TALKING ABOUT,01:22:49
THERE'S A LOT OF STUFF IN THERE
THAT IS EITHER NOT HOOKED UP01:22:53
BECAUSE WE NEVER TESTED IT,
SO WE DON'T KNOW,01:22:56
OR IT IS HOOKED UP, AND WE
JUST DIDN'T NEED TO USE IT.01:23:00
AND IT IS --
IT IS QUITE EXTENSIVE.01:23:01
IT IS A VERY,
VERY EXTENSIVE SYSTEM.01:23:04
THIS ISN'T A, LIKE,01:23:08
JUST SOMETHING
THAT SOMEBODY THREW TOGETHER.01:23:10
THERE WAS A LOT OF THOUGHT,
TIME,01:23:12
AND A LOT OF TALENTED ENGINEERS
HERE AT EPIC,01:23:15
WHO WORKED AT STUDIOS LIKE
BIOWARE,01:23:19
I FORGOT THE NAME OF THE STUDIO
THAT MADE EVER QUEST.01:23:21
BUT BIOWARE, ONE OF OUR GAMEPLAY
PROGRAMMERS CAME FROM THERE,01:23:27
AND HE BUILT SYSTEMS
LIKE THIS THERE.01:23:29
THIS IS VERY SIMILAR
TO ANY TYPE OF SYSTEM01:23:32
YOU WOULD SEE USED
ON A MAJOR AAA TITLE ENGINE.01:23:35
>>PAULO: IT IS AN
ENGINE WITHIN AN ENGINE.01:23:37
>> [ LAUGHTER ].01:23:38
>>PAULO: AN ENGINE TO DO SORT OF RPG
KIND OF GAMES01:23:42
THAT NEED REALLY
COMPLEX INTERACTIONS,01:23:45
WHERE YOU NEED TO CHECK,
"I HAVE AN ABILITY01:23:48
AND I NEED TO APPLY THIS ABILITY
TO ANOTHER PLAYER,01:23:50
WHAT ARE THE ABILITIES
THAT THIS PLAYER HAS,01:23:53
DOES IT HAVE AN ABILITY
WITH A CERTAIN COOLDOWN,01:23:56
SO LET'S SAY,
YOU CAN LITERALLY --01:23:59
I DON'T WANT TO NAME NAMES,01:24:01
BUT IT IS SOMETIMES A CALLED
AN MMO ENGINE,01:24:07
AND EVEN THOUGH WITHOUT
ALL THE RELIANT ASPECTS OF IT,01:24:10
IT IS MADE FOR THESE
KIND OF COMPLEX GAMES01:24:13
WHERE YOU NEED THIS
COMPLEX INTERACTION01:24:16
THAT YOU SEE FROM AN RPG.
IT IS A VERY POWERFUL SYSTEM,01:24:20
AND IF YOU --
IF YOU ARE GOING THAT --01:24:23
IF YOU ARE GOING TO MAKE
THAT KIND OF GAME.01:24:28
>>VICTOR: EACH
PROJECT IS ITS OWN.01:24:30
AND LIKE PAULO
MENTIONED EARLIER,01:24:33
SOMETIMES THIS IS THE DECISION
THAT YOU HAVE TO MAKE,01:24:36
EVEN THOUGH YOU HAVE
A NICE FRAMEWORK TO BUILD UPON.01:24:38
>>SAM: UH-HUH.01:24:40
>>VICTOR: I THINK THAT'S ALL
THE QUESTIONS THAT WE GOT01:24:44
YOU GUYS CAN ANSWER?01:24:45
>>AMANDA: WE WILL
WRAP IT UP FOR THIS WEEK.01:24:47
I FEEL LIKE THERE'S LOADS
OF INFORMATION,01:24:51
SO THANK YOU FOR JOINING
IN THIS WEEK,01:24:53
AND THANK YOU
FOR CALLING IN, PAULO.01:24:56
>>PAULO: THANK YOU.01:24:57
>>AMANDA: HE IS GOING FOR
DISTANCE, HAHA. A CHAMPION.01:25:01
SO THIS IS ALL INCREDIBLY
VALUABLE STUFF01:25:04
AND THERE'S A LOT
OF QUESTIONS AROUND IT,01:25:06
AND EVEN MORE THAT
WE DIDN'T GET TO.01:25:07
SO WE CAN ALWAYS --
IF SOME OF THESE ARE VALUABLE01:25:12
AND IF YOU FEEL LIKE YOU
CAN ANSWER SOME OF THESE,01:25:15
MAYBE WE CAN PULL THEM TOGETHER.01:25:16
>>SAM: YEAH,
WE LETS PULL THEM01:25:17
TOGETHER AND SEE WHAT
WE CAN ANSWER, BECAUSE01:25:19
SOME OF THESE QUESTIONS,
AS THEY PROGRESS,01:25:21
THEY MIGHT NOT MATTER ANYMORE01:25:23
BECAUSE WE WENT AWAY FROM WHAT
THIS QUESTION IS TARGETING AT.01:25:27
BECAUSE WE ARE TRYING TO UPDATE
THIS WITH JUST ANYTHING01:25:32
AND EVERYTHING DEVELOPERS
COME AND ASK QUESTIONS ABOUT,01:25:34
WE ARE TRYING TO PUT THIS
INTO THIS PROJECT,01:25:36
SO YOU HAVE SOME DOCS,01:25:37
BUT YOU ALSO
HAVE A HANDS-ON EXAMPLE.01:25:41
>>AMANDA: YEAH, WE WILL
TRY TO TOSS THOSE OVER TO YOU,01:25:43
AND FOLLOW UP ON THE FORUM
THREADS SO IT IS SOMETHING01:25:46
THAT YOU CAN COME BACK
AND REFERENCE AND CHAT ABOUT.01:25:50
