Spawning a mon once a spell is cast and/or finished [Lua]

[felindalei]

I was wondering on how to spawn a mob after a mob casts a spell, or a mob s
pawns on the player once the spell's duration is finished, this would be a BIG help if anyone can, plz and thank you.

in the phase where he casts the spell add
x = pUnit:GetX()
y = pUnit:GetY()
z = pUnit:GetZ()
o = pUnit:GetO()
pUnit:SpawnCreature(npcid, x, y, z, o, faction, how long you want him out in milliseconds)

(btw 0 is permanent)

example

function Boar_Mini (pUnit, Event)
         x = pUnit:GetX();
         y = pUnit:GetY();
         z = pUnit:GetZ();
         o = pUnit:GetO();
pUnit:SpawnCreature(800009, x-10, y-2, z, 20, 14, 0);
pUnit:SendChatMessage(42, 0, "Agathelos Spawns a Minion!")
end

the sendchatmessage above as 42 is a raid warning. I added -10 so the mob appears a little bit away instead of right on him.

if you dont have pUnit, you could use Unit instead

function Boar_Mini (Unit, Event)
         x = Unit:GetX();
         y = Unit:GetY();
         z = Unit:GetZ();
         o = Unit:GetO();
Unit:SpawnCreature(800009, x-10, y-2, z, 20, 14, 0);
Unit:SendChatMessage(42, 0, "Agathelos Spawns a Minion!")
end

Is better if you write:

Unit:SpawnCreature(800009, Unit:GetX()+2, Unit:GetY()+2, Unit:GetZ()+0.1, Unit:GetO(), Unit:GetFaction(), 0)

Because that way you don't define global variables unnecessarily.
