How do I make a player assign to a team via touching a block?

I want a player to be assigned to a team when they touch a block, any help would be great

every player got a teamcolor propery if that color is the same as the color of an actual team, then the player will be in that team.

so simply do a touch event and change the teamcolor property of the player. use the first parameeter of touched and it will return a part of the character. then you can do :getplayerfromcharacter and from there you can simply just change the teamcolor.
