How would I make it to where people can not join a subplace through that place instance?

Basically I wanna make it to where people have to join through the STARTPLACE and not through the other place instances connected to the game. How would I script that?

Unless they somehow manage to get to the subplace through an existing game implementation, prevent them when they land, e.g. when they join(and kick them).

Otherwise, don’t use TeleportService to that subplace(completely nuking the only way) or prevent teleportation by setting some checks before.

? im not asking that i’m asking how to prevent them from joining the sub place through the subplace instance not teleporting there

I’m fairly certain that if you set a specific place as the Starter Place, players will automatically be placed there, even if they try to directly join your subplaces.
