One Way Collision

RondoRocket

Does anyone know of a way (or trick) to create one way collision so an actor can pass through a non-movable actor but not go back?

I'll give an example when jumping that worked for me.

You need to constrain the Player's Y position to an attribute.

--
When Player collides with Platform
and Player.Y > Platform.Y + (Height of Platform)

Then Bounce with object
--

That way the player only collides when it's above the platform, but can still pass through it

Or you could say that when self.motion.Y > 0 collide. This means that only when the actor is falling will it bounce off the object.

Cool, I'll give these ideas a shot. Thanks a lot for your help, guys!

Still no luck. I tried the examples but I'm trying to make a platformer where the actor can jump up to another platform directly from below. Seems like I need to have some level of restitution on for this to work but I just want my actor to land and not bounce. Any thoughts?

Thanks for any help.

In my post I meant when self.motion.Y is < 0. My bad! That should work.
