Is it possible to change Collision Polygon at runtime?

Can I change the Collision Polygon of an object at runtime? Add / remove nodes and move nodes around?

It's not supported. The engine caches collision poly data in various places, so if you change it the caches won't update and things will be broken.

Thanks Ashley !

Less work for me I guess

Use an invisible shape as your collision polygon, pin it to your player or sprite. If you need to change it, destroy it and pin a different shaped invisible object to your sprite. Just like using a square or rectangle, but you can use any shape you want.

BluePhaze yeah people will have to do that. I was asking because it could have been useful inside my plugin
