With cloud variables.

Simplest way to do it for 2 players:
Make seven variables. Make all of them except for player ID CLOUD variables by pressing the ‘cloud data: stored on server’ checkmark.

(cloud check)
(xp1)
(yp1)
(xp2)
(yp2)
(amountOfPlayers)
(player ID)

set cloud check to one. When someone tries to run the program and he can read the cloud variable, that means he is connected to the cloud. He will not be if he is on the offline editor, or a new scratcher. In the first instance we check if it is set to one, then we tell him he is connected. If it is zero, the default variable value, the game will tell him that he is not connected or is a new scratcher.

In player1:

when green flag clicked
forever

if <[cloud check] = [1 ]> then

if <[player ID] = [1 ]> then

go to x: (xp1) y: (yp1)
end

end

end

when green flag clicked
if <[cloud check] = [ 1]> then

if <[amountOfPlayers] = [ 0]> then

set [player ID v] to [player 1 ]
change [amountOfPlayers v] by (1)
broadcast [connected v]
forever

if <key [left arrow v] pressed?> then

change [xp1 v] by (5)
end

if <key [right arrow v] pressed?> then

change [xp1 v] by (-5)
end

if <key [up arrow v] pressed?> then

change [yp1 v] by (5)
end

if <key [down arrow v] pressed?> then

change [yp1 v] by (-5)
end

end

end

end



when green flag clicked
if <[cloud check] = [ 1]> then

if <[amountOfPlayers] = [ 2]> then

broadcast [sorry, the server is full! v]
end

end

when green flag clicked
if <[cloud check] = [0]> then

broadcast [sorry, not connected! v]
end

Do nearly the same script in your second player. Here is what it should look like:

when green flag clicked
forever

if <[cloud check] = [1 ]> then

if <[player ID] = [2 ]> then

go to x: (xp2) y: (yp2)
end

end

end

when green flag clicked
if <[cloud check] = [ 1]> then

if <[amountOfPlayers] = [ 1]> then

set [player ID v] to [player 2 ]
change [amountOfPlayers v] by (1)
broadcast [connected v]
forever

if <key [left arrow v] pressed?> then

change [xp2 v] by (5)
end

if <key [right arrow v] pressed?> then

change [xp2 v] by (-5)
end

if <key [up arrow v] pressed?> then

change [yp2 v] by (5)
end

if <key [down arrow v] pressed?> then

change [yp2 v] by (-5)
end

end

end

end

When the broadcasts are broadcasted, a sprite should tell the player the message of the broadcast.

For the rest of this to see if a player has left or not, go to the scratch wiki: https://wiki.scratch.mit.edu/wiki/How_to_Make_a_Multiplayer_Game
Here nearly everything is done the same way. Use the player 1 and 2 checks and the local ones to check if a player has left or not. You could also just do the whole tutorial from there than from here if you want.

Well, I already know,but i want to see if there is another way

It's not that easy you think it is to create a multiplayer, First you need to get known to cloud vars, Try creating highscore lists, username encrypting etc, Then look at @maximcaux's post, That's the easiest way to create a multiplayer game.

Don't advertise.

https://scratch.mit.edu/projects/77775784/ may help - you don't need 7 cloud variables for 2 players but you do have to use cloud variables if by multiplayer you mean people on different computers.
