You can create custom weaponry from deriving from one of the following classes: - Gun - Melee - Weapon - Carriable Gun provides common useful methods such as ShootBullet that gun like weapons would find useful (derived from Weapon) Melee has an Attack method (derived from Weapon) Weapon provides reload and ammo system and no more (derived from Carriable) Carriable provides nothing, its a bare bones thing that goes into your inventory and has a viewmodel

heres an example weapon you might find helpful
