Called when primary attack button ( +attack ) is pressed. When in singleplayer, this function is only called in the server realm. When in multiplayer, the hook will be called on both the server and the client in order to allow for Prediction. You can force the hook to always be called on client like this: if ( game. SinglePlayer() ) then self:CallOnClient( "PrimaryAttack" ) end Note that due to prediction, in multiplayer SWEP:PrimaryAttack is called multiple times per one "shot" with the gun. To work around that, use IsFirstTimePredicted.

This hook will be called before Player movement is processed on the client, and after on the server. This hook only runs while the weapon is in players hands. It does not run while it is carried by an NPC. This will not be run during deploy animations after a serverside-only deploy. This usually happens after picking up and dropping an object with +use.
