Okay, this is bugging me a bit. I had this scene envisioned, wherein the player would walk under a vent, and hear barney yell "EAT THIS" then the vent cover would break and an armed grenade (monster_handgrenade) would drop out of the vent.
But now I've found that monster_handgrenade is'nt coded as an entity, it's just in the FGD. I've tried an env_shooter with an env_explosion on the ground under it, but that looks bad, since half the time the 'grenade' is under the floor.
Does anyone have any ideas on how I can salvage this?
