How do I create Team Limit on Multiplayer?

I created a game with a team system, but "the system isn't too smart". I am trying to make the game balanced with 5 players in each team.

Here is what i did until now:

- Player Create or join a room.

- when he/she joins a game it randomly pick a team color and spawn at the team color, etc...

- But it don't have a limit... if everyone want to be the same team by re-entering the room it will be possible... how do i Fix that? I am almost thinking in a way to do it, but i can't figured it out yet.

And also, i am trying to make a Custom Room, where the player select the number of players on the team in general like: 3 players, or 5 player for each team.

Have you tried using global variable?

Ja tentou usar variavel global?

I see what I can do...

Estou vendo o que consigo fazer...
