Bug

It seems ÉpéeistMicro has a bug somewhere in its gun code. It's throwing "ArrayIndexOutOfBounds" and "NullPointer" exceptions, especially against mirror bots.

The only change I made to the GF code was to change the constant MEA from .7 to 0.727272727272727272727273.

Any ideas?

Thanks

        Looks, like here you have a problem: [(int)enemyDistance / 200] Distance may be more than 800 units (sqrt(800*800 + 600*600)=1000), but you give for this dimension only 4 elements It's another problem, but i cannot find out other problems by codereview and it's too late to debugging it, sorry
