Can you set the collider for an animation to be something other than a rectangle or square? My student has a sprite that he wants the collider to mimic the shape of the object. Is there a way to do that?

Hensleyn,

I don’t know and I’ll push this one to the team, but in the meantime from the [Intro to U3L18](https://studio.code.org/s/csd3-2018/stage/18/puzzle/1) if you click on the [“setCollider” block](https://docs.code.org/gamelab/setCollider/) it gives you the documentation which you can change the size and rotation which might help in the meantime.

Looking forward to figuring this out together!

Brad
