[Lua] Spell Problem

[Sumething 2 r3member]

Well I've been doing lua for about 10-15 min now and I made this script

local King_Varian_Wyrnn

function King_Varian_Wyrnn_Define(Unit, Event)
King_Varian_Wyrnn = Unit
end

function King_Varian_Wyrnn_OnCombat(Unit, Event)
Unit:SendChatMessage(14, 0, "Look what we have here... the horde. After all the time we've let you live in peace, this is what it comes to. A bloody battle that nobody will forget. The existence of the horde will be no more...")
Unit:RegisterEvent("Phase_1", 1000, 0)
end

function King_Varian_Wyrnn_OnDied(Unit, Event)
Unit:SendChatMessage(14, 0, "What... have... I... done?")
end

function King_Varian_Wyrnn_OnLeaveCombat(Unit, Event)
Unit:SendChatMessage(14, 0, "Cowards!")
end

function King_Varian_Wyrnn_OnKilledTarget(Unit, dEvent)
Unit:SendChatMessage(14, 0, "Another Horde dead. So weak.")
end

function Phase_1(Unit, Event)
if Unit:GetHealthPct() <= 90 then
Unit:RemoveEvents()
Unit:SendChatMessage(14, 0, "You will soon be dead!")
Unit:CastSpellOnTarget(41484, Unit:GetRandomPlayer(1))
Unit:RegisterEvent("FireBall", 35000, 0)
end
end

function FireBall(Unit, Event)
Unit:CastSpellOnTarget(41484, Unit:GetRandomPlayer(1))
end

RegisterUnitEvent(49582, 1, "King_Varian_Wyrnn_OnCombat")
RegisterUnitEvent(49582, 2, "King_Varian_Wyrnn_OnLeaveCombat")
RegisterUnitEvent(49582, 3, "King_Varian_Wyrnn_OnKilledTarget")
RegisterUnitEvent(49582, 4, "King_Varian_Wyrnn_OnDied")

And the problem is I try to get him to cast a fireball (Which he does) but he fires it at himself... I've tried all sorts of things, I checked the spell to see if it worked properly and it did.

I tried changing..

Unit:CastSpellOnTarget(41484,Unit:GetRandomPlayer(1)

To different flags such as...

:GetRandomPlayer(flag)
RANDOM_ANY = 0,
 
RANDOM_IN_SHORTRANGE = 1,
 
RANDOM_IN_MIDRANGE = 2,
 
RANDOM_IN_LONGRANGE = 3,
 
RANDOM_WITH_MANA = 4,
 
RANDOM_WITH_RAGE = 5,
 
RANDOM_WITH_ENERGY = 6,
 
RANDOM_NOT_MAINTANK= 7

I've also tried

:GetClosestPlayer()
:GetMainTank()
:GetAddTank()

But sadly still nothing. So if you can please help me I will +Rep when I can lol.

CastSpellOnTarget is sadly bugged, and so will always cast on him self.
You need to do FullCastSpellOnTarget and it should get him, but to save getting errors in console if somone logouts quickly or such you would do this:

function spell(pUnit, Event)
local player = pUnit:GetRandomPlayer(0)
if player == nil then -- If nobody was targeted
else -- Otherwise they were
pUnit:FullCastSpellOnTarget(11, player) -- 11 spell id
end
end

Note: I am using pUnit but it doesn't really matter if you use unit Unit or pUnit as long as you define it right in the function (pUnit, Event) part.
