I was receiving a lot of complaints about throwing knives not throwing in close-quarters combat, meaning the attacker would deal a 17hp knife hit rather than a 57hp (or whatever you have your throwing knife damage set to) knife hit. To fix this I added the bolded code. It would be trivial to make this a CVAR setting. It currently doesn't check to see if you melee attack the head (a headshot) and instead treats all melee knifings as body shots.
If a player is too close to throw a knife but left clicks the victim then it counts the same amount of damage as a throwing knife would and subtracts one knife from the attackers available knives. If the attacker has no throwing knives left then normal melee damage occurs. Right clicks are unaffected and work normally. The only issue I can see right now is that the melee knife hits are counting twice (the normal 17hp damage + the throwing knife damage) but this could be fixed very easily as well.
Code:
// if lemurs had knives,
// they would throw them!
