I'm using an image with transparency as a Sprite. The image has an irregular shape:
http://sinkingsensation.com/stuff/shape.png I'd like to detect collisions with it. My current strategy is to draw a polygon (pygame.draw.polygon) behind the image. That works, but its difficult to make the polygon accurately reflect the image, and I need to make a lot of them. So I'm wondering if there's some way to detect collisions with the image itself? Or maybe there's some clever way to draw a polygon based on an image? I don't need pixel-by-pixel accuracy, anything close would work.
