How to do a one-off collision?

[guy]

I'm making a really small game where the player has to reach a door to get to the next level. The door has really simple collision detection where if the player is colliding with it then the collision function returns true. I just wanted to know if there's a way to make it return true just one time instead of every frame when something is colliding with it.

Have a variable 'door_collided' which is set to false at the beginning of the level. Check for collision only when it is false. Set it to true when the player collides with the door.

Have a variable 'door_collided' which is set to false at the beginning of the level. Check for collision only when it is false. Set it to true when the player collides with the door.

Or a table named Collided with all the objects that are currently in collision. like

Code: Select all

if collided["door"] then
	next_level()
elseif collided["monster_guy001"] then
	lives = lives -1 
	restart_from_checkpoint()
--ETCETERA

Thanks a bunch. I didn't realize it was so simple!
