It will have to be able to check for collision between two polygon frames like those in the above image and similar shapes. I would like to avoid having to try and make triangles out of the frames.
I am not great at math myself, which is why I am asking for someone to help me out with this problem. I think that I have a good and useful sprite module going, but without polygon frame collision, its probably a lot less useful.
Info on the sprite module, for those interested in knowing more, can be found here:
