CastSpellOnTarget - Root mob while casting?

[Iaccidentallytwink]

I'm scripting a mob using LUA, and I'm wondering if it's possible to root the mob during the event that makes him cast a spell, say, Chain Lightning. If I use something like Frost Nova he casts it normally, but otherwise he begins casting then stops to chase me.

The code I have for the spell is:

function Thrall_Chain_Lightning(Unit, Event)
Unit:FullCastSpellOnTarget(15117,Unit:GetClosestPlayer(0))
end

You can use this as an example:

function Thrall_Chain_Lightning(Unit, Event)
Unit:Root()
Unit:FullCastSpellOnTarget(15117,Unit:GetClosestPlayer(0))
Unit:RegisterEvent("Thrall_Unroot", 1000, 1) -- Replace 1000 with the desired time to unroot in MS.
end

function Thrall_Unroot(Unit, Event)
Unit:Unroot()
end

You can use this as an example:

function Thrall_Chain_Lightning(Unit, Event)
Unit:Root()
Unit:FullCastSpellOnTarget(15117,Unit:GetClosestPlayer(0))
Unit:RegisterEvent("Thrall_Unroot", 1000, 1) -- Replace 1000 with the desired time to unroot in MS.
end

function Thrall_Unroot(Unit, Event)
Unit:Unroot()
end

Thank you very much! Trying this out now.

Ah, I've tried it but if I manually root him (say, frost nove), during the root he unroots and follows me =S.

Other with Unit:StopMovement.

function Thrall_Chain_Lightning(Unit, Event)
Unit:FullCastSpellOnTarget(15117,Unit:GetClosestPlayer(0))
Unit:StopMovement(XXXX)  -- add casttime in milliseconds, 3seconds cast= 3000, make 3200, looks better^^
end

how can i open a thread?

Other with Unit:StopMovement.

function Thrall_Chain_Lightning(Unit, Event)
Unit:Root()
Unit:FullCastSpellOnTarget(15117,Unit:GetClosestPlayer(0))
Unit:StopMovement(XXXX)  -- add casttime in milliseconds maybe 100ms + or something :P
end

What's the point of having Root in there?

[TheZaronz]

Nothing in that case it will root him permanently.
Just do as Xendro said - should work better.

Unit:StopMovement(X) -- for the amount of time in MS

You could have him cast a rooting spell on himself instantly (like the GM shackle) and after casting the spell to remove it

The only thing you need to do is:

function Threall_Chain_Lightning(Unit, Event)
Unit:StopMovement(99999999)
Unit:SetCombatMeleeCapable(1)
Unit:FullCastSpellOnTarget(15117, Unit:GetRandomPlayer(0))
Unit:RegisterEvent("End_Chain", 5000, 0)
end

function End_Chain(Unit, Event)
Unit:RemoveEvents()
Unit:SetCombatMeleeCapable(0)
Unit:StopMovement(0)
end

I gurantee this will work. Need to change the 5000 on register event to how long you want it to stop moving.

[Iaccidentallytwink]

Thanks, I'll try this!

Stoneharry, that code ends up rooting the mob forever, and he just stands there =S.
Here's the code I have for it.

function Thrall_Chain_Lightning(Unit, Event)
Unit:StopMovement(9999)
Unit:SetCombatMeleeCapable(1)
Unit:FullCastSpellOnTarget(15117,Unit:GetRandomEnemy(0))
Unit:RegisterEvent("End_Chain", 3000, 0)
end

function Varian_Whirlwind4(Unit, Event)
Unit:StopMovement(9999)
Unit:SetCombatMeleeCapable(1)
Unit:FullCastSpell(8989)
Unit:RegisterEvent("End_Chain", 3000, 0)
end

function End_Chain(Unit, Event)
Unit:RemoveEvents()
Unit:SetCombatMeleeCapable(0)
Unit:StopMovement(0)
end

The Stop movement 0 should reset his movement, always worked for me in the past. Try setting the second stop movement to 1000. If that doesn't work change the first stop movement to the seconds you want it to stop moving (1000 = 1 second) then delete the 2nd one.
