Im using ColiisionHandlerQueue() to get some simple collision detection going as this is my first project with collision detection. And so far its failed, HORRIBLY lol. after hours of trying to get just simple “object hit other object” print statements i got nothing. Then finally i got this code

Game()
run()and it gives me a TON of cillision info when i load up the game but then it doesnt record any of my collisions with the world or ai ship. I just want to be able to detect when my ship (and later a simple bullet) is colliding with another ship. Any suggestions? heres a screenie of my overloaded console when i load up my game ( the game lags too =/)
