I often see the question "How do I spawn stuff like crates or npc's?"
So I decided to make a example map for it.
I'm sure all the mappers for gmod will enjoy this.
It shows use of the func_button, point_template and prop_physic.
The prop_physic could also be func_physbox or something.
Oh, as a lil' twist, the spawned crate will explode when you shoot it.
"Clone spawning"
You hide an NPC somewhere in the map, and then, you set out a points that copies that certain NPC and spawns the copies.
Great if you need them to do stuff after spawn.
But I can't figgure out how. :S
The moderator removed the comments of the tard I was responding to.
I really wouldn't know how to solve that problem now, haven't been mapping for HL2 in ages, but i'm sure you've found out now.
LEGO BRICKS! Eh, anyway, nice tutorial
