Passable physics objects

I was running and watching and YT some Box2D demos and in one of them it was shown that B2D allows for making object passable if approached from arbitrary directions (think one way platforms). Could you implement this in GD?

//edit: After some googling, I’ve found this:

You should be able to reproduce a bit this behavior with the events : Check the example/template called “CastleDoodle” which is using Physics with one way platforms :slight_smile:
