What happens when you aren't suppose to have a weapon in a certain gamemode for minigames, and you just type !knife which gives you the ability to kill people when you shouldn't be able, or when you aren't suppose to have a melee weapon but a gun only?

It would be cool to add but too many variables that we'd have to think of.

function CheckKnife()
    if engine.ActiveGamemode() == "GAMEMODENAME" then
          return true 
     else 
         return false 
    end 
end 

usage:

hook.Add("PlayerSpawn", "GiveKnife", function()
	if CheckKnife() then 
		ply:Give("weapon_knife")
	end 
end)
