This mod allows you to throw knives at enemies. To do this, holding a knife in your hands, press the "throw a grenade" button (by default, the "G" key) to switch to throwing knives. And use the "fire" button to throw at the enemy. To switch back to a regular knife, you must press the same button.
Installation: Place ThrowingKnives.dll in the "scripts" folder. You will need ScriptHookV and ScriptHookVDotNet.
