grenade_apache_rpg

This entity is not in the FGD by default.
It should not be put directly in a map because it can only be configured through code in Steam versions of the game. You still can use it in mod version of the game via Hammer.

Rocket's model in Steam versions of the game.

Rocket's model in the mod version of the game.

grenade_apache_rpg is a point entity available in Black Mesa. The grenade entity that used by npc_apache. The rocket that launched by rocket launcher from Apache helicopter. Most inputs and outputs are same as CBaseAnimating.

Represented by class CGrenade_ApacheRPG.

Note:It explodes if hits skybox in the mod version. In Steam versions, it just disappears.

Bug:This grenade entity can stuck at dynamic (not physics) objects, such as prop_dynamic. In such situation, rocket will not move until it explodes. Usually happens with objects that have a dynamic collision, or objects that are in motion.

Tip:If you need to fix this issue, use trigger_weaponfire that will kill stucked rockets, this trigger should be toggled by logic_timer every 0.5-1.0 seconds.
