EVENT_DRAWWEAPON is a Game Event.
This event is called when a weapon is being displayed on the screen.
Set gamevar RETURN to any non-zero value to hide weapon tile. The constantly updated variable currentweapon should be used with this event, i.e do not use your own declared variables, otherwise when the player attempts to switch weapons, raising/lowering of the new weapon will be glitched.
The difference between EVENT_DISPLAYWEAPON and EVENT_DRAWWEAPON is that the second doesn't hide the quick kick tile. EVENT_DRAWWEAPON may be useful if you don't plan to re-do the quick kick.
