How do i make a person's individual spawn point?

Im making a game where people have different bases. How do I make it where the spawn point only spawns the owner and not the rest? Thanks in advance.

I wont answer with a full script, because u didnt give us your script attempt, but it may have something to do with connecting to player when a player joins and moving them to a random part base if it isn't already taken by another player by recording player names, uh yea....
