Okay well i went to find out what writes to this address and i got
004c6e0d is the address to nop(right?) 29 54 88 04 are the bytes, for 4(right?) and sub [eax+ecx*4+04],edx is the instruction to decrease ammo(right?)
Code:
Change of 004c6e0d - 29 54 88 04 - sub [eax+ecx*4+04],edx

i took out the ()'s in
