Hi guys, im in need of an accurate method of detecting a collision between two DisplayObjects. Also it would be nice if the collision also delivered info on how a ball should react to the collision.

Ive read up a bit on pixel perfect collisions using small bitmaps. However my attempts are not proving succesful. Im semi done with a Class that does what i want but i cant get it to work properly.

If anyone seems up for the task of fixing it i wouldnt mind sending it.  
Other than that, anyone have something similar to the class im looking for ?

Pixel perfect, bounce hittest 🙂
