Oh yeah, you need to put an array into the server class that has all the cannon x and y's.. I'd probably make a List if i re-did it now.

/win, could you post your following?

Good luck

Good job, + now you can't remove!Muahahahahaha! Nah but this is REALLY nice, and it wouldn't take a brain sergeant to implement this in with the cannon rotating tutorial that's out there...Thanks!Rep for you

Good job Boomer.
