I think it would be nice if the editor could recognize colours or shapes to create collision masks automatically or an event to separate a sprite from a colour.
For example, you have a maze map and doesn’t want to touch the black lines, instead of adding individual lines to the map, you can add an image and takes you away from the black lines.
Dynamic masks are an existing request: [Request]: More advanced collision masks - #2 by Nttgames
and an alternate take of one-time mask creation: [Request] "Magic wand"
I think the primary reason why dynamic masks aren’t possible currently is due to not allowing for concave collision masks. There is a larger discussion on the github and in the above threads on that.
However, as this is an existing request elsewhere, I’m going to close this thread out.
