Using line-intersection I can figure out whether these collide, and have written a working Collide() function. This is to be used in a variable step timed game, and therefore (as shown below) in Frame 1 the right polygon is not colliding, it's perfectly normal for on Frame 2 for the polygons to be right inside each other, with the right polygon having...
