From Shaggy(anti-hiding In House)
 

ok some people act like they want their room first. probably a extra account that they have. but when u give them the room and they enter they log out.
this is what you do. you add a npc that is like


if(playerenters)playerx = ?;
if(playerenters)playery = ?;

something liek that

this will cause them to be in a certain spot when they log in even if they have a key

err wts

I do that for every level i make anyway to stop lag...
That is, levels with one entrance and exit.
