Update collision mask with distortion

Hello. I played first time with distortions and noticed two problems:

1) Distortions don't work unless distortion map has same amount of rows and columns. I just messes up and looks glitchy if there ar for example 4 rows and 10 columns. Edit: Filed a buf of this.

2) The collision mask doesn't update with distortions.

I tried to find workarounds for 2, but with little success. I tried to paste the sprite into a canvas, but I have no clue how to handle collisions with canvas. Is there a way?

You can update the collision mask of the canvas through events. Just do something like this:

+Always

-Clear canvas to transparent

-Paste Sprite into canvas

-Update collision mask

That will give you a constantly changing collision mask on the canvas.
