func_tow

func_tow is a brush entity available in Black Mesa. This is  BGM-71 TOW used by the HECU. Can be used by player and HECU soldiers. Unlike other entities based on func_tank entity, this entity needs manual reload after each shoot, the ammunition is item_tow_missile (must be holded by player, simple touching of this object to func_tow will not reload this weapon). All inputs, outputs and flags are same as func_tank, properties as well, but some have special notes.

Represented by class CFuncTOW.

Note:The fire, deploy and reload sounds are hardcoded. You still can change both in your Black Mesa mod by replacing the sounds with a blank sounds and playing your own sounds via input/output system.

Note:Only certain NPCs (npc_human_commander, npc_human_grenadier, npc_human_grunt and npc_human_medic) can use this weapon via FindNPCToManTank input. Other will ignore this input.

Important:This entity can't be used without model combination (will not fire).

Warning:It is not recommended to use enabled collision for model, it will cause missiles to explode when fired.

Bug:NPC's weapon breaks after this gun usage. It doesn't removes, but becomes invisible and unable to shoot (NPC still reload weapon several times, for some reason). This breaks the AI ​​partially, because such NPC still thinks that it have functional weapon. (not in )
