KNIFE MOD

[Tally]

Given your code (i had a quick look) the knife doesnt do any damage while flying.

The knife weapon file fires "invisible" bullets to kill players/bots. There is a script which runs an animated knife model, which rotates in the air, but this is mere cosmetics. Its the knife weapon file which actually kills. It's just that it has no muzzle flash or sound we normally associate with a weapon fired in COD.
