Headcrab Launcher NPC

Sorry if this has already been requested, I know, I’m retarded. So I’m just requesting a Headcrab Launcher npc that randomly fires headcrab canisters throughout a map. I assume this wouldn’t take much work since it has already been made but somebody just needs to fix it. Thanks. I hope somebody is willing to do this or is gonna tell me that it isn’t possible.

its possible, but you could probably just wire up a contraption for that.

I’m not all that good with wire. In fact, I’m terrible at wire. I only know how to make a simple turret. This would be too advanced for me.

Well than i would keep looking around…

No, I want an NPC. You know, non-player controlled.
