Change collision mask at runtime

Is this possible?

This isn't supported. However you can often achieve the same effect by composing objects out of multiple sprites, and moving those sprites at runtime.

Yeah, just create a sprite with the same anim frame throughout the animation and set the collision mask differently on each frame. Then when you want to use a different mask, switch to that anim frame.

I just said what Ashley did I think. :/ lol

Cheers, unfortunately this won't work for me as I need the circle mask. Making my own collision mask by points is nowhere near as accurate as selecting the circle mask from the drop down menu. It's okay I got around it by spawning another instance of a identical shape with the correct mask and I just show and hide while the game is on the Thanks for the Input
