[Question] Spawning NPC on top of the Main Tank

[choweyiii]

I made a script that is kind of like fire that you would stand in, in a raid, but a lot more ghetto, and I wanted to know how to spawn the fire npc on the main tank, or a random player. Will Rep any help.

Deadly Deadly Fire Script

function DeadlyDeadlyFire_OnCombat(Unit, Event)
  Unit:Root(99999999999999999)
  Unit:RegisterEvent("DeadlyDeadlyFire_TimetoDie", 500, 0)
  Unit:Despawn(10000, 0)
  end

function DeadlyDeadlyFire_TimetoDie(Unit, Event)
  Unit:CastSpellAoF(Unit:GetX(), Unit:GetY(), Unit:GetZ(), 72170) --flame strike
end
  
function DeadlyDeadlyFire_OnDied(Unit, Event)
  Unit:RemoveEvents()
  Unit:Despawn(1,0)
end

function DeadlyDeadlyFire_OnLeaveCombat(Unit, Event)
  Unit:RemoveEvents()
  Unit:Despawn(1,0)
end

RegisterUnitEvent(900047, 1, "DeadlyDeadlyFire_OnCombat")
RegisterUnitEvent(900047, 4, "DeadlyDeadlyFire_OnDied")
RegisterUnitEvent(900047, 2, "DeadlyDeadlyFire_OnLeaveCombat")

Scizzle, Spawner of the Deadly Deadly Fire script so far (Broken)

function ScizzleDeadlyDeadlyFireSpawner_OnCombat(Unit, Event)
  Unit:Root(99999999999999999)
  Unit:RegisterEvent("ScizzleDeadlyDeadlyFireSpawner_TimetoDie", 500, 0)
  end

function ScizzleDeadlyDeadlyFireSpawner_TimetoDie(Unit, Event)
  Unit:SpawnCreature(900047, Unit:GetMainTank(), Unit:GetX(), Unit:GetY(), Unit:GetZ(), 2212, 10000)
end
  
function ScizzleDeadlyDeadlyFireSpawner_OnDied(Unit, Event)
  Unit:RemoveEvents()
  Unit:Despawn(1,0)
end

function ScizzleDeadlyDeadlyFireSpawner_OnLeaveCombat(Unit, Event)
  Unit:RemoveEvents()
  Unit:Despawn(1,0)
end

RegisterUnitEvent(900048, 1, "ScizzleDeadlyDeadlyFireSpawner_OnCombat")
RegisterUnitEvent(900048, 4, "ScizzleDeadlyDeadlyFireSpawner_OnDied")
RegisterUnitEvent(900048, 2, "ScizzleDeadlyDeadlyFireSpawner_OnLeaveCombat")

:Root() has no parameters, so remove the 999999999999999999999999999999999999999999999999999999999.

I believe this would crash, since the events are still be fired even though the creature has despawned. Instead have an event happen in 10 seconds that removes events then despawns (1,0).

To spawn on the player you would do:

local plr = pUnit:GetRandomPlayer(0) -- Change to what you need
if plr ~= nil then
pUnit:SpawnCreature(id, plr:GetX(), plr:GetY(), plr:GetZ(), plr:GetO(), faction, time)
end
