What I mean is those variables don’t exist. event contains a predefined, set of read-only variables. You can’t assign new ones to it. You probably meant something like goto start_pos_x,start_pos_y.
But in your specific example I would probably just tell the player where to go from the room’s enter handler like so:
Oh man! That is so much simpler! I didn't know you could do that. I thought everything that affects the player had to be in the player script! Sorry, I'm new to this (second day). Thank you!!!
