lesson 9 list of servers

00:00:04

in this video we will touch on such an important

00:00:06

thing as creating a session and connecting to

00:00:09

sessions in the first part we will create

00:00:11

umg widgets namely for creating a session

00:00:13

that is for a multiplayer game and

00:00:16

for connecting to other sessions this

00:00:18

will be a list of servers the

00:00:20

name will be displayed here number of players and

00:00:22

Pink from the second part we will already start

00:00:24

programming, we will learn how to create our own

00:00:26

session so that players can connect to us, and

00:00:29

in the third part we will already connect to

00:00:31

other people’s sessions through the list of servers and in the

00:00:33

end we will test it all

00:00:38

[music]

00:00:47

part 1 creation of widgets

00:00:51

will begin with the creation the main widget

00:00:54

will be called server sheet, it will

00:00:56

contain a list of servers in the folder I will hand over the

00:00:58

server sheet folder

00:01:02

and in it I will create a server sheet widget.

00:01:06

In our game, a panel with information about

00:01:09

players and chat have the same style, it is

00:01:11

such a darkened blurred panel with

00:01:13

rounded edges background blur and

00:01:16

so that don’t copy it constantly and don’t

00:01:18

customize it, let’s create a separate widget with

00:01:20

it that will contain this window with a

00:01:22

customized style, create a new widget

00:01:25

called blure Style folders and copy

00:01:28

this Blur panel from the scoreboard widget,

00:01:36

now go to the Blur Style widget and

00:01:38

paste it, remove

00:01:39

everything unnecessary, I’ll leave only

00:01:42

background Blur we created this panel

00:01:44

in previous lessons here Blur strang at 30

00:01:46

blure radius 40 and rounding 20 also

00:01:50

indents on all edges 12 and now in order to

00:01:53

place elements from another widget into it

00:01:54

we will move the

00:01:57

namends Slot element inside and here it should be emphasized that

00:01:59

it is better to immediately rename the Slot for example

00:02:02

add some numbers at the end or for

00:02:04

example My Name Slot, if you don’t

00:02:07

do this, problems may arise.

00:02:09

Anything you place the Slot widget the engine

00:02:11

can mark as Trash and after the

00:02:12

next start of the engine these elements

00:02:14

will be deleted. And if you

00:02:16

rename the Slot widget then

00:02:18

the contents may be deleted Therefore, it is better to

00:02:20

immediately rename this slot

00:02:23

style is ready now we can go to the

00:02:26

widget server sheet and in User created

00:02:29

find bluestyle drag and drop now

00:02:31

thanks to the slot inside it you can

00:02:33

place various elements, you just

00:02:35

need to drag and drop into the slot it is

00:02:37

called Naim Slot 0 we

00:02:41

will also take the necessary elements

00:02:43

scoreboard widget And this will be all in the contents,

00:02:46

copy

00:02:52

and paste into the slot,

00:02:55

now remove the unnecessary stuff, these are the inscriptions

00:02:58

player name, rename it to server name

00:03:03

and remove the Kills column,

00:03:06

also remove everything from bottom to

00:03:11

top, add buttons, take a button from the

00:03:14

widget, chat box

00:03:27

for it, we will need Horizon Box,

00:03:37

drag it to the top Horizon Box,

00:03:40

paste the copied button here,

00:03:43

change the text to an angle bracket, this will be a

00:03:45

button to go back, the text will be size 19,

00:03:51

then add text,

00:03:54

center it, add text server sheet,

00:03:59

stretch it across the entire width, then copy

00:04:02

the button and paste

00:04:07

the text again, replace it with Fresh, this will be a

00:04:10

list update button

00:04:11

Let's replace the inscription Death with the player

00:04:15

and the list with servers will be in the

00:04:17

scroll box; we'll copy this element from the

00:04:19

chat; it

00:04:22

just has a scrollbar configured. And we

00:04:24

stick to the same style

00:04:30

for the strip with names; we'll indent

00:04:33

12 from the bottom;

00:04:37

we'll rename the key elements; a button to

00:04:40

exit this menu; Back Button;

00:04:43

Refresh wraffresh Button

00:04:47

scroll box that will contain a

00:04:49

list of servers

00:04:52

server list

00:04:54

and stretch the scrollbox serverlist across the entire

00:04:57

window by clicking Phil the

00:05:00

main style is ready to be

00:05:04

located this widget will be in the

00:05:06

main menu go to the Main

00:05:09

Menu widget this is the main menu here we have

00:05:11

the main one add a server list button

00:05:13

just copy one

00:05:16

and simply insert the vertical box in which

00:05:18

these buttons are located

00:05:21

and drag it to the top,

00:05:23

change the inscription to the server sheet,

00:05:27

when you click on this button, the

00:05:28

previously created widget will open. That

00:05:30

is, the entire menu will disappear and the

00:05:32

server sheet widget will appear.

00:05:33

We will switch using the

00:05:36

switcher widget And we will place all the contents menu

00:05:38

widget switcher

00:05:43

and now let's add a server sheet widget to it

00:05:46

under index 0 in switchery we

00:05:48

will have the main menu and under index 0 the

00:05:50

server sheet but we have the server sheet on the whole

00:05:53

screen, make it smaller, place it

00:05:56

inside the canvas panel,

00:05:59

make it the right size

00:06:05

and align it in the center, using element,

00:06:11

round the dimensions,

00:06:13

ready to

00:06:16

open, we will open the server sheet in the

00:06:19

main menu, take its events.

00:06:23

Take the variable from the evening

00:06:28

and call Set Active Index widget

00:06:31

server sheet We have under index 1,

00:06:34

now we will close the server sheet,

00:06:36

go to the server sheet widget, call

00:06:40

events on pressing return buttons,

00:06:43

create a dispatcher event with the name

00:06:46

unbackbutton press,

00:06:48

make a count and connect with the button,

00:06:52

return to the Main Menu widget in the

00:06:55

designer where the hierarchy is selected, select the server

00:06:57

list and it will have an available event,

00:07:00

backbutton Press, this is our Ivan dispatcher

00:07:03

for pressing the button, that is, we press the

00:07:05

button in the server widget the sheet and the menu widget

00:07:07

understand this will set a zero

00:07:10

index for the switches with my menu,

00:07:14

check it, open the menu on Escape, press

00:07:17

the button and the server sheet appears, we

00:07:20

can also close it and the

00:07:22

entire menu closes on Escape,

00:07:27

now we will create a line that will

00:07:29

contain information about the server, these

00:07:31

lines will be located in the column of the

00:07:32

widget server sheet and here We will also

00:07:35

copy the style from another widget player

00:07:38

Score copy everything in the folder server sheet

00:07:41

create a new widget server info

00:07:47

now go to it and paste what we

00:07:50

copied

00:07:52

remove the unnecessary skull icon and Kills deft

00:07:57

with rename it to player

00:07:59

ready go to server sheet

00:08:03

and add the widget server info scrollbox

00:08:06

this will be temporary for clarity

00:08:12

This is how it will look

00:08:16

it was for example so delete it

00:08:19

clear the scrollbox server sheet from

00:08:22

widgets server info

00:08:25

change the labels in the widget server info

00:08:34

now create a panel for creating a

00:08:36

server this is a new widget Create Server

00:08:38

let's go to it, the background will be a bluestyle widget,

00:08:43

we'll take the structure from the server, we'll

00:08:51

remove the unnecessary sheet, we'll leave only up with a

00:08:54

back button,

00:08:56

we'll change the title to Create Server,

00:08:58

we'll remove the Refresh button, here there will be

00:09:01

options for setting up the server,

00:09:03

this is the inscription and the option itself, they will be

00:09:05

located in a column, take them from

00:09:07

Main Menu as a basis,

00:09:10

for example, this element is perfect

00:09:17

mindesired type of inscription let's make 200

00:09:21

and for the entire horizonbox line we'll add

00:09:24

a bottom indent of 12 we'll need 4 such

00:09:27

elements copy them the

00:09:31

first option will be server name

00:09:35

second server Map

00:09:37

3 maximum number of players and

00:09:40

fourth whether the session is local

00:09:42

now let's change The server settings fields themselves

00:09:45

will be an input field, a text box,

00:09:47

take it from the main menu. Let's

00:09:59

narrow this field, the padding at the top and bottom

00:10:02

will be 10. Go further, the

00:10:08

Map server will be a combo box, we already

00:10:12

have a ready-made combo box style,

00:10:13

it's located in the Option 2 widget. we used

00:10:16

in the graphics settings, namely choosing the

00:10:18

screen resolution,

00:10:20

then Max players, this will also be a

00:10:23

textbox, but we will make it narrower; we will set the

00:10:27

minimum designer type to 100

00:10:30

and by default the quantity will be entered there;

00:10:32

it will be 2;

00:10:34

LAN; we will leave it as it is; it will be a

00:10:36

checkbox;

00:10:43

the style is ready, all that

00:10:45

remains is to add the Create Server button,

00:10:47

again, take it from my menu,

00:10:55

ready to

00:10:56

call the event for pressing the Back button,

00:10:59

add an evandispatcher for the Back button,

00:11:02

call it Back Button Press, here we

00:11:09

will duplicate the Create Server widget and

00:11:11

call it creat Single widget for

00:11:13

creating a single game,

00:11:15

change the labels

00:11:22

and we’ll remove what is not required in a single-player

00:11:24

game MAX Player, let’s leave it for now, there’s

00:11:27

no point in it, so in the future, you never know,

00:11:29

bots will be added to the game. Of course,

00:11:32

inheritance could be used here. But since

00:11:34

we only have two such widgets, there’s no

00:11:35

need

00:11:37

to add these widgets. in the main menu,

00:11:39

go to the menu and add the

00:11:43

switcher widget of our Create Server menu

00:11:46

and a single server,

00:11:50

these will be indexes 2 and 3, also place

00:11:53

them in the canvas panel,

00:12:02

adjust the dimensions,

00:12:07

align to the center,

00:12:12

do the same with the Create Single widget,

00:12:15

take the width from the Create Server widget

00:12:23

align

00:12:27

ready

00:12:32

set up the switching logic take

00:12:35

events on the Click of the Create and Single buttons

00:12:43

free them from the logic

00:12:46

and switch the corresponding

00:12:48

index

00:13:03

don’t forget about the buttons to go back

00:13:27

check

00:13:34

everything works

00:13:38

after we open the widget the server

00:13:41

sheet will load sessions They are the same

00:13:44

servers but this loading process

00:13:46

takes time and so that the player, while

00:13:48

waiting, understands that loading is in progress, we will

00:13:49

add an element displaying this

00:13:52

loading, go to the server widget, the

00:13:54

server sheet will be displayed in a scroll box,

00:13:56

it is also called a server sheet, and while

00:13:59

loading is in progress, we will replace it with

00:14:00

another widget, so we will place a scroll

00:14:02

box server sheet widget switcher now

00:14:06

this scroll box is under index 0 and to

00:14:09

display the loading process in the section

00:14:11

primitive serkilor fraer

00:14:15

these are dots running in a circle,

00:14:17

we will center this element

00:14:20

here below you can adjust the

00:14:22

number of dots period and make the radius

00:14:25

60 and if there are no servers we will add an inscription

00:14:28

to servers we will add text to we

00:14:31

center the same switch,

00:14:35

change the inscription to the new servers,

00:14:37

set the size to 60 and in Color and apacity Alpha

00:14:40

make it 02 so that it is dim

00:14:43

settings in the switcher the loading wheel

00:14:46

will be at the beginning index 0 then the

00:14:49

server sheet index 1 index 2 will go to the inscription No

00:14:53

servers remember this location

00:14:59

we will change cursor when hovering over a button,

00:15:01

this can be done using the setcursor

00:15:07

or in the element settings, click on

00:15:11

it,

00:15:12

start with the button go back to

00:15:15

details in the search, write cursor, check

00:15:17

the box and select the type of cursor, this will be

00:15:21

hand, and

00:15:36

finally go to the widget server info,

00:15:39

this will be a line displaying information

00:15:41

about the session on the server, let's make the

00:15:44

cursor change completely when hovering

00:15:46

over it. Go to the defaults class and

00:15:50

find the cursor settings here. This is

00:15:57

what it will look like.

00:16:02

Part 2: creating your session,

00:16:06

we can start programming.

00:16:09

Close all unnecessary tabs; leave

00:16:12

only what relates to the server sheet; let's

00:16:15

start by creating a session. go to the

00:16:18

Create Server widget in the graph,

00:16:24

everything related to creating a session

00:16:27

is in the online Session tab,

00:16:30

these are the functions

00:16:34

we will call them Here they are all to create a

00:16:37

delete session, search for a session, this

00:16:42

function returns an array of sessions That is,

00:16:44

all sessions that were created by other

00:16:46

players Here we get a structure with

00:16:48

information of the session and we can already get

00:16:51

from it the number of playing players

00:16:54

the maximum number of players Pink

00:16:58

and the name

00:17:01

there is also a function to join the

00:17:03

session As we can see They have such a clock

00:17:07

This means that it will take some

00:17:09

time to execute after which the function

00:17:12

will report success or failure I will remind

00:17:16

the session is a union of players into a single

00:17:19

network, these functions are available by default in the

00:17:21

engine, but there is a more advanced

00:17:24

version of them, Advance Session, this is a separate

00:17:26

free plugin, we will touch on it later,

00:17:28

but now we will make simple logic for

00:17:31

creating a session, call it to press the

00:17:34

Create Server button,

00:17:37

attach the Create Session function to it,

00:17:42

attach a controller

00:17:46

here we indicate the maximum

00:17:48

number of players and whether the session is

00:17:50

local Let the number of players

00:17:52

be two and upon completion of

00:17:55

this function you need to open the card for sex,

00:17:58

take Open level by name here You need to

00:18:01

enter the name of the card and you need to pass the

00:18:03

parameters to Option this is lysen or server

00:18:06

in our case this will be a bald server,

00:18:07

so we’ll enter bald through this field, you can

00:18:10

transfer information, for example, some

00:18:12

variables, essentially all this logic

00:18:15

will create a session,

00:18:19

now we’ll make it so that you can

00:18:20

configure the session through the Create

00:18:23

Server widget, let’s start by selecting a card,

00:18:26

take the variable of this combo box And

00:18:29

we will fill it with cards Of course,

00:18:31

you can create an array in advance And place

00:18:33

cards there, but we will make a logic that

00:18:35

takes all existing levels in the project,

00:18:37

take get ast, register, pull

00:18:41

get by Class,

00:18:44

we will look for asats of the class World, these

00:18:47

are the levels,

00:18:49

here we will get their array,

00:18:53

we will get this using a loop forex loop

00:18:56

we break the breakasetdata structure

00:19:00

and we need Asad name this is the name of the level

00:19:03

we will place it in the combo box

00:19:06

using adoption

00:19:14

and we also need to display the selected

00:19:17

element That is what is displayed in the

00:19:19

collapsed list Let it always be the

00:19:21

first element index zero index

00:19:25

and we hang this on the construct,

00:19:39

now all the cards from the project have been pulled up, we

00:19:45

will continue the logic when we press the

00:19:48

Create Server button. We can also do this

00:19:49

with a created session, so we

00:19:52

first need to delete the session at the

00:19:54

beginning;

00:20:09

we will get the text

00:20:13

and check whether the text

00:20:15

from the empti is not empty,

00:20:18

at the same time we will add a check so that the specified

00:20:20

number of players is not less than zero

00:20:22

or 0, first we convert to string, we take the

00:20:26

comparison greater than string,

00:20:29

we convert integer

00:20:32

and compare with zero

00:20:34

to comply with the conditions here it must be

00:20:37

True That is, this means the entered number is

00:20:39

greater than zero and the text from the emka displays True

00:20:42

if the line is empty, take not boolean

00:20:46

at the end will be True if here is false

00:20:50

now take endbyan

00:20:54

if its Input is True

00:20:57

then here is True This means that all

00:20:59

conditions are met, that is, the line

00:21:01

is not empty

00:21:03

and the number is greater than zero

00:21:06

We can hang this on brunch

00:21:10

and check for empty server name string.

00:21:12

Also hanging branch

00:21:16

Falls will mean that the line is filled.

00:21:21

Next comes a check for the number of players line

00:21:24

and if here then we can hang logic to

00:21:27

create a session,

00:21:37

first we check whether the field with the

00:21:40

server name is filled, if not is filled then

00:21:43

True is called so the subsequent

00:21:45

logic hangs on false

00:21:47

then we check the field with the number of

00:21:49

players, here two conditions must be met: the

00:21:51

field must not be empty and the specified

00:21:54

number must be greater than zero these are all

00:21:55

Boolean operations that can be combined as

00:21:57

you like I just did it this way Well, here are

00:22:00

the necessary ones we have completed the verification operations,

00:22:02

now we can transfer data for the session,

00:22:06

the maximum number of players,

00:22:10

for convenience, we will rename the variables

00:22:14

Get servername

00:22:17

getmap

00:22:19

getmax Player

00:22:22

getlan

00:22:27

we will transfer the session the maximum number of

00:22:29

players,

00:22:33

then whether the session is local, this is the

00:22:36

getlan checkbox variable, we take a hit somewhere

00:22:42

after creating the session, the Map opens

00:22:45

in the level name you need to enter the name, take the

00:22:48

getmap variable,

00:22:51

this is the map that we will select in the

00:22:54

Get selected Option combo box,

00:23:01

pass the selected name,

00:23:06

connect all the logic.

00:23:08

After clicking the Create Server button, we

00:23:11

delete the session in case it

00:23:13

was created and then the logic will be

00:23:14

attached to Access and filer, that is, it

00:23:17

works for us in any case, finally

00:23:19

let the player know that they correctly kept

00:23:21

some indicators And this is the name of the server and the

00:23:24

number of players, take the variables

00:23:26

of these lines and take Set Error,

00:23:31

write the reason

00:23:34

for the name it will be empty

00:23:37

and for the number of players incorrectly

00:23:43

connect these functions with branches

00:23:48

That is, if the line does not pass the check

00:23:50

that we did for the input lines,

00:23:53

then these functions will be called and an error will be displayed,

00:24:00

look, we have a missing name,

00:24:04

press the Creed Server button, an error will appear,

00:24:07

enter the name but enter

00:24:09

the number of players incorrectly. That is, it is either

00:24:11

empty the column is either 0 or less than 0 and

00:24:14

an error also appears.

00:24:16

And if you fill everything out correctly and click the

00:24:19

Create Server button, then everything will work and

00:24:21

the session will be created.

00:24:25

We’ll create the logic for Create Single, that is,

00:24:27

to create a single game, we’ll copy

00:24:30

the logic to fill the combo box with all

00:24:33

possible cards.

00:24:35

Now let’s move on in Create Single,

00:24:38

select the combo box, rename its

00:24:40

variable to getmap,

00:24:46

go to the graph,

00:24:48

take the variable

00:24:50

and attach the copied logic to Construct,

00:24:59

in principle, we can not change this variable,

00:25:01

they have the same name, we

00:25:04

take it by clicking the creat Single button

00:25:11

and we will simply open the selected map,

00:25:14

first we get it

00:25:17

getzlocket Option

00:25:19

and open using the

00:25:24

Option card Compose empty Connect and

00:25:28

you're done

00:25:37

Select some map, for example

00:25:39

Open World,

00:25:41

load

00:25:47

the truth, we won't be able to play

00:25:49

because nothing is configured for it

00:25:54

part 3 connect to other sessions the

00:25:58

climax let's create a server

00:26:01

sheet list of servers go to the widget

00:26:04

server list into its logic, we will immediately

00:26:07

call the findsation function, we will attach

00:26:10

it to the contract, we

00:26:12

will pass the controller into it

00:26:15

and indicate the maximum number of

00:26:16

displayed servers, let it be 100. As

00:26:19

a result, this function will give us an array

00:26:22

of sessions, that is, an array of servers, we will output

00:26:24

it using the Forge loop, we will

00:26:27

check whether the number is there are

00:26:29

more than zero servers If yes, then we will display them

00:26:31

And if not, we will display the load,

00:26:33

take Long and attach the comparison operator

00:26:36

to the brunch

00:26:39

if with Access we check whether the

00:26:42

number of servers is greater than zero If yes, then

00:26:44

display an array with servers, set it to

00:26:46

false and get here a session is a

00:26:49

data structure about it if sessions are

00:26:51

found then there will be sex, then we check

00:26:54

whether the number of servers is greater than

00:26:55

zero That is, if the number is zero

00:26:57

then True and on Falls we have a loop

00:27:00

that displays an array And Here we

00:27:03

get the session data structure the loop

00:27:05

will create widgets server info this is

00:27:08

this a line with information about the server,

00:27:14

we create a Server info widget, we

00:27:17

will also connect a controller here

00:27:22

and we will add this widget to a scrollbox

00:27:25

in the column,

00:27:27

we take the scrolbox variable, we

00:27:30

called it server sheet and attach it from

00:27:33

Child,

00:27:35

as we remember, the scrollbox displaying the

00:27:37

server is placed with a switcher widget, it has a

00:27:40

loading wheel under index 0

00:27:42

the server itself list servers index 1 index 2

00:27:46

No servers this is if there are no servers,

00:27:49

take the variable of this switcher Set

00:27:52

activejid set the second index this

00:27:55

logic will work if the session is not

00:27:58

found we attach it to the file and also

00:28:01

hang it on the branch pipes That is, if

00:28:03

the number of servers is 0

00:28:05

now we will make the logic for Refresh buttons,

00:28:08

we take events for pressing it, we

00:28:10

delete old servers so that the array is not

00:28:12

replenished with identical sessions, we take the

00:28:15

server list variable, this is scrollbox

00:28:17

clearchildren,

00:28:20

and we switch the switcher widget to the zero

00:28:23

index,

00:28:26

and then the logic for outputting servers is triggered again,

00:28:33

and let’s not forget that if sessions were

00:28:35

found, then this sweater needs to be switched

00:28:37

to the first index the

00:28:43

entire session we display remains to be filled with

00:28:46

information widget server.info this

00:28:49

information about the session name number of

00:28:51

players Pink and we also need to do so that

00:28:54

when we click on the server we can

00:28:56

join it go to the widget

00:28:59

server info Graph we need to get

00:29:02

information we received information about the session

00:29:04

through this function was called in the

00:29:07

server sheet widget Server info we will

00:29:09

transfer information about the session the

00:29:12

data structure through a variable

00:29:14

we will create a new variable called

00:29:17

Session and the type we will select blueprint

00:29:19

sessional result we will

00:29:21

make it open

00:29:23

and check the expalson Spawn box we

00:29:26

will transfer our session to it from the

00:29:29

sheet server widget, go to the sheet server,

00:29:32

find the GCD that creates the

00:29:35

info server widget, update it, the

00:29:37

Session input appears here and pass here our session

00:29:40

that we received from the

00:29:42

findsation array, go back to the info server,

00:29:48

catch this session and get from it

00:29:50

Data

00:29:52

geoserver name Get Pink

00:29:56

current number of players maximum

00:29:59

number of players

00:30:01

Now we will place this data in the

00:30:03

appropriate positions,

00:30:05

we will call the sector for these fields We just

00:30:08

take their variables, by the way, for convenience,

00:30:10

we can rename them

00:30:11

and make a set of text

00:30:14

here we will place the information we

00:30:16

will connect all the logic

00:30:19

we will hang on the construct

00:30:22

We will pass the name

00:30:23

Then we will transfer it to one column two

00:30:26

values, the current number of players and the

00:30:28

maximum, let's take the format text

00:30:31

and here in curly brackets we write the name of the

00:30:34

input variables kyront then put

00:30:37

a slash it will separate these parameters on

00:30:39

the logic it does not affect in any way it's just

00:30:41

text the next parameter Max

00:30:44

Enter and add here current and MAX

00:30:47

Player the

00:30:53

final touch is output Pink let's

00:30:57

arrange this logic in a more understandable

00:30:59

form,

00:31:00

ready

00:31:04

and the final touch will be done so

00:31:07

that when you click on the session. More precisely,

00:31:09

on the server info widget, this is the line

00:31:12

we connected to the session, go function

00:31:15

override on the left there are events on

00:31:18

Mouse, we can take double Click double Click

00:31:21

or Button Down when we press the button

00:31:23

let it be, it will create a separate

00:31:26

function for pressing but inside the function we

00:31:29

cannot call Join Session so

00:31:30

we return Graph and here we will simply

00:31:32

create a custom event let it be

00:31:34

called Join Session and

00:31:37

hang Join Session on it,

00:31:39

attach the controller

00:31:42

and the most important thing is to transfer the structure with

00:31:45

information let's join the session,

00:31:48

as we remember, it was transmitted through the

00:31:50

Session variable

00:31:53

in previous lessons, when we

00:31:54

connected to another player, we

00:31:56

joined his card through the

00:31:58

Open level GCD. As you can see, we do

00:32:00

n’t need to do this now. We connect via

00:32:01

Join Session. Now we’ll call this event

00:32:05

on a mouse click and

00:32:08

compile it. and we see that it gives an error

00:32:10

so that this does not happen output notes when

00:32:12

connecting Make and winterplay everything is ready

00:32:16

should be emphasized when we create a

00:32:18

session for another someone else’s session we will no longer be

00:32:21

able to connect to

00:32:23

do this We will need to

00:32:24

first destroy our session in

00:32:26

which we are and then

00:32:28

connect exactly the same For a client,

00:32:30

if we log into a session,

00:32:33

we won’t be able to log into another. Here we will also

00:32:35

have to delete our session. Therefore,

00:32:37

we will call when creating a single

00:32:40

game And to glue the server, we’ll start with creat

00:32:43

Server; creating a server, go to its

00:32:46

widget; here we already have there is a

00:32:48

destroyceion function. It hangs at the beginning. This is

00:32:50

good for debugging, but it’s better to

00:32:52

hang it before creating a session

00:33:10

and Create Session will be attached to the

00:33:12

sex file because

00:33:14

we will not always create a session while being in another.

00:33:19

We’ll do the same in creat Single before

00:33:22

opening the map.

00:33:34

And the third place is when connecting to the

00:33:37

server, we connect through the server

00:33:39

info, that is, when we click on this

00:33:41

widget, it turns out that we first

00:33:43

disconnect and then connect to the

00:33:45

session,

00:33:50

check what we did, click the ellipsis

00:33:53

here we will put 4 players, also instead of the

00:33:57

bald server we will select Standalone and

00:33:59

launch it as a Standalone Game, we

00:34:04

will create a session on in the first client,

00:34:25

now let's create a session on the second client,

00:34:28

but it will be local, check the LAN box,

00:34:38

also go to the server sheet and see the

00:34:40

session of the first client

00:34:44

from the first client, we also see the session of the

00:34:47

second client, but we don't see ours

00:34:50

now from the third client, open the server

00:34:52

sheet, here we see all the created sessions

00:34:55

local and non-local

00:34:59

We see that the session name is generated

00:35:01

automatically;

00:35:03

we can’t change it via blueprint; this is done via C++,

00:35:05

so the line where we set the

00:35:07

server name will remain for the future; for now, it’s of

00:35:09

no use; let’s join

00:35:12

one of them. Let it be a session

00:35:14

whose name ends on c39,

00:35:27

now we join the c39 session with 4

00:35:30

clients,

00:35:34

now all three players are assembled, press

00:35:36

phrases to update the list of servers

00:35:40

and connect to the session where there are three

00:35:42

players from the first client, we are all in the same

00:35:45

session and one of the Host players is an important

00:35:48

detail if the session is filled with players then

00:35:50

it will not be displayed in the list of

00:35:51

sessions

00:35:54

from the first client, let's create our own

00:35:56

separate session by disconnecting from the general one

00:36:02

and now we will be out of the session from the Host, I'll

00:36:04

remind you This was the Second client, just

00:36:07

like Open the map

00:36:13

and all clients are disconnected from the session and

00:36:15

thrown into the main menu

00:36:17

If a network failure occurs then

00:36:20

special events can be called,

00:36:22

they are available in the Game instance,

00:36:25

we have already created the Game instance object, here it is here Ivan

00:36:28

Network Error, it is called when the

00:36:30

network is collected. For example, if the connection was lost,

00:36:32

this function can return the cause of

00:36:34

the error;

00:36:37

there is also a Travel Error, it can be

00:36:39

called, for example, If you do not have the

00:36:40

required card that is on the server.

00:36:46

Finally, an important detail should be noted:

00:36:48

if you have a Gray and not a white IP, then

00:36:51

other players will not be able to connect to you,

00:36:52

the easiest option is to

00:36:54

use a VPN like hamach or

00:36:56

redmin, but this method is only

00:36:58

needed for testing for a normal game a

00:37:00

proxy server for a tunnel connection

00:37:02

is simply a layer that will

00:37:04

connect players, we talked about it in the

00:37:06

very first lesson How multiplayer works,

00:37:10

third-party services such as

00:37:13

Steam or Epic Games will help you cope with this problem, for this you need to

00:37:16

use their special API and

00:37:18

plugins, this topic will be discussed. in

00:37:20

subsequent lessons, subscribe to
