   Help with java 2d...
  Hi, I am doing a project with bouncing ball! I have managed to get the ball bouncing, but now i need to deal with collision detection using trees, and to be honest i dont know where to start. I have spent 2 days thinking of what to do, but its only delaying my exam revision, so i really want to get this out of the way so i can get on with my exams revision!! Please help, any ideas will be very much appreciated!Thanks for your time!
