Hey, I found this example of simple collision detection:  Simple Collision and really liked it and decided to borrow it and mold it to my needs and to also jump into inheritance. Most of the time it works extraordinary but every once-in-awhile it goes haywire and decides to detect a random collision although your character isn't even close to the ellipse/square. So, basically, my question is there a more efficient way of doing simple collision detection or a way to fix this? I think this might be part of the problem, that the glitch tends to only happen on my Mac, V.10.5.8 along with a problem with my robot script... I don't really want to post the code, so it would be helpful if you could answer with just knowledge or I could provide more detail.
