Func tank

func_tank
Type	brush
Status	supported

The func_tank is used to represent a mounted cannon which can be controlled by players as well as monsters, if allowed. For either to be able to use this, it must be hooked up to a single func_tankcontrols entity. If you want func_tank to be controllable by player, you need to specify a name of func_tank and use func_tankcontrols entity in addition of this entity. Automatic turret needs "Active" flag enabled. Entity requires origin brush tied to barrel, so it can rotate around it.
