Spawning Npcs into the map, through a timer then setting states on the npcs. [Help please!]

[xrayhunter1]

Hey, i got the npc to spawn and stuff. But the NPC will not set his health, i have no clue why.
I've tried many things.

Attempt #1

local npc = ents.Create("npc_zombie")
			npc:SetNWInt("level", 255) // because the lolz and testing reasons...
			npc:Fire("hp", 45*npc:GetNWInt("level"), 0)
			npc:SetPos(Vector(0,0,0))
			npc:Spawn()
			npc:Activate()

Attempt #2

local npc = ents.Create("npc_zombie")
			npc:SetNWInt("level", 255) // because the lolz and testing reasons...
			npc:Fire("health", 45*npc:GetNWInt("level"), 0)
			npc:SetPos(Vector(0,0,0))
			npc:Spawn()
			npc:Activate()

Attempt 3#

local npc = ents.Create("npc_zombie")
			npc:SetNWInt("level", 255) // because the lolz and testing reasons...
			npc:SetHealth(45*npc:GetNWInt("level"))
			npc:SetPos(Vector(0,0,0))
			npc:Spawn()
			npc:Activate()

Attempt 4#

local npc = ents.Create("npc_zombie")
			npc:SetNWInt("level", 255) // because the lolz and testing reasons...
			npc:SetHealth(200)
			npc:SetPos(Vector(0,0,0))
			npc:Spawn()
			npc:Activate()

I have no clue why its causing problems.
What i am thinking the npc, will have to be in its own npc code example:

Class = "npc_zombiehp500",      
            Model = "models/zombie_classic.mdl",
            Health = "500",
            KeyValues = {},
            Category = "Zombies GRAHHHH!!!"    }

Which that system will suck... Also if i do that, what keyvalues should i put for zombies?

Thanks, hope you can help!

Try setting the health after you spawn it. IIRC spawning an entity will reset its health to default

I have a few examples on spawning enemies on map start and respawning on death or timer:

With respawn

One time spawn

And yes, as code_gs says, SetHealth when it spawned.

Thank you everyone responding, i'm going to try your suggestions. Also, would i have permission Acecool, of using your code not entirely but, just to get an idea whats going on. Of course in my way coding it.
