Basic Scripted NPC Broken?

[url]http://wiki.garrysmod.com/?title=Basic_Scripted_NPC[/url]

I've tried 100 different ways to get scripted NPCs working, is it possible i'm missing something?

The best I can get is a NPC to face your direction.

I understand states, tasks, schedules I just can't seem to get anything to work.

Anything you can help me with would be awesome.

.... What exactly do you need help with?

Here's my init.lua, this results in the NPC being spawned and constantly called schdChase but it never does anything in game.

AddCSLuaFile( "cl_init.lua" )
AddCSLuaFile( "shared.lua" )

include('shared.lua')

ENT.m_iClass = CLASS_COMBINE




function ENT:SpawnFunction( ply, tr )

	Msg("Entering Spawn\n")
	if ( !tr.Hit ) then return end
	
	local SpawnPos = tr.HitPos + tr.HitNormal * 20
	
	local ent = ents.Create( "npc_mercenary" )
	
	ent:SetPos( SpawnPos )
	ent:Spawn()
	ent:Activate()
	
	Msg("Exiting Spawn\n")
	
	return ent
	
end

function ENT:Initialize()

	Msg("Entering Init\n")

	self:SetModel( "models/Combine_Soldier_PrisonGuard.mdl" )

	self:SetHullType( HULL_HUMAN )  
    self:SetHullSizeNormal()  
       
    self:SetSolid( SOLID_BBOX )    
    self:SetMoveType( MOVETYPE_STEP )   
       
    self:CapabilitiesAdd( CAP_MOVE_GROUND | CAP_OPEN_DOORS | CAP_ANIMATEDFACE | CAP_TURN_HEAD | CAP_USE_SHOT_REGULATOR | CAP_AIM_GUN )   
       
    self:SetMaxYawSpeed( 500 )   
       
    self:SetHealth( 100 )
	self:Give("weapon_smg1")
	
	Msg("Exiting Init\n")

end

function ENT:OnTakeDamage( dmg )   
  
    local NewHealth = self:Health() - dmg:GetDamage()  
  
    if NewHealth <= 0 then  
        self:SetNPCState( NPC_STATE_DEAD ) -- We have to do this or else SCHED_DIE_RAGDOLL won't work  
        self:SetSchedule( SCHED_DIE_RAGDOLL )  
    end  
      
    self:SetHealth( NewHealth )  
      
end
