Hello all! I have spent today working on a good set of functions to test collision in my game (I'm expecting to finish my character tomorrow) and I'm very happy! The method I used was finding the distance betweent the circles (I used the pythagoreon theorem!) and then seeing if the distance was less than either circles radius. It doesn't work for ovals (Only perfect circles), however the circles can have different diameters. Do you know how I can check collision for Ovals also? I've been thinking through the problem all day, however I've had no luck. Cheers !
