Are currently trying to map a SP Map, i have made a trigger, when the trigger is triggerd a headcrab spawn, and then i want the headcrab to move to a location. How do i do the last part?

....
1. Trigger = ON
2. Headcrab = Spawned
3. Headcrab move = HELP PLEASE :P

Something to do with a npc_hint I think, have you checked out the valve wiki? there must be a few tutorials out.

I made a path_corner but they won't move to it.

NPC_Headcrab
name: level01_npc
target path corner: waypoint01

FLAGS:
Fall to ground
Template NPC
-----

NPC_templatemaker
name: level01
name of template NPC: level01_npc

-----

Path_corner
name: waypoint01

----
trigger_once

Output: On Trigger level01 enable

They spawn, but won't move :/
