Collision for non transparent objects

Hi, I don't know if this can be done , but was wondering if it is possible and I don't know how to go about it.

Currently, I have one PNG image. It has some transparency in it. Is there some way to ignore the transparent part of the image, and apply collision only to the non-transparent part of the PNG file? Right now it is taking the whole image as one, and I have to manually create collision boxes and set it to invisible, and then overlap it with the visible parts of the PNG.

Oh, maybe I should mention that it is a square which is enclose with no openings, and the transparency is inside that square.

When you go into the sprite editor the last tool on the left under hotspot is a tool that lets you create custom collision points. You can draw a man with a knife and. Set your collision to the knife alone if that was what one wanted.

Sounds to me like you are already doing it in the only possible way.

You can't make an open space within a collision polygon.

Why not just use the currently invisible objects and make them visible to create the box? The transparancy within the sprite is taking up useless graphic-memory.

Woah. That is such creative genius level of thinking. I will try it now.

Mind = Blown.
