LUA script help/information

[Ascelyn]

So I have a few questions about LUA scripting

function Mage_OnCombat (Unit, Event)
Unit:RegisterEvent("Mage_Frostbolt",10000, 0)
Unit:RegisterEvent("Mage_Frostnova",35000, 0)
Unit:RegisterEvent("Mage_Barrier", 40000, 2)
Unit:RegisterEvent("Mage_Evocation",1000,0)
end



function Mage_Frostbolt(pUnit, Event)
pUnit:FullCastSpellOnTarget (42842, pUnit:GetRandomPlayer(0) )
end

function Mage_Frostnova(pUnit, Event)
pUnit:CastSpell (42917)
end

function Mage_Barrier(pUnit, Event)
pUnit:CastSpell (36481)
end

function Mage_OnDied (Unit, Event)
Unit:RemoveEvents()
end

function Mage_OnKilledTarget (Unit, Event)
end

function Mage_OnLeaveCombat (Unit, Event)
Unit:RemoveEvents()
end

RegisterUnitEvent (1759, 1, "Mage_OnCombat")
RegisterUnitEvent (1759, 2, "Mage_OnLeaveCombat")
RegisterUnitEvent(1759, 3, "Mage_OnKilledTarget")
RegisterUnitEvent(1759, 4, "Mage_OnDied")

So this is my script for a mage ( I'm new at LU so no flaming pls :P)
But when my mob runs out of mana, He still tries to cast his spells..

1. I've tried adding something like

function Mage_Evocation(Unit, event, miscunit, misc)
	if Unit:GetManaPct() < 25 and Didthat == 0 then
		print "Mage Evocation"
		Unit:FullCastSpell(30254)
		Didthat = 1
	else
	end
	end

in it but he doesnt cast the evocation so if you could help me with that

2.But what would be even better is, Is there any code or function so the mob knows when he doesnt have enough mana, He doesnt need to cast the spell? :P

3. They always seem to cast the spell on me only, even when they're fighting against other hostile mobs.

Thanks in advance.

I think your function doesn't work because you need to define what Didthat is.
Add at the top of the script outside any functions:

local Didthat = 0

Then on death / leave combat:

Didthat = 0

As for checking when casting the spell:

function x(pUnit, Event)
   if pUnit:GetManaPct() < 25 then
   pUnit:FullCastSpell(

30254) -- Evocation

   else
   local plr = pUnit:GetRandomPlayer(0)
   if plr == nil then
   else
   pUnit:FullCastSpellOnTarget(11, plr)
   end
   end
end

To make a creature cast a spell on another creature, you have to define the hostile creature first.

local Hostile

function Hastile_Spawned(pUnit, Event)
     Hostile = pUnit
end

RegisterUnitEvent(npcid, 18, "Hastile_Spawned") -- 6 with some Lua engines


-- FURTHER DOWN IN THE SAME SCRIPT ON THE NPC YOU WANT TO CAST A SPELL ON THE OTHER WITH
-- HAS TO BE SAME SCRIPT

function X(pUnit, Event)
      pUnit:FullCastSpellOnTarget(11, Hostile)
end

Good luck

Edit: Code boxes screwed up, you get the idea.

Thanks man really +rep

[Ascelyn]

But eh, So you have to make another script for a creature you want your mob to atk? So there's no possibility that you can script it so it attacks both players and other creatures?

and could you define the last part? O.o

local plr = pUnit:GetRandomPlayer(0)
if plr == nil then
else
pUnit:FullCastSpellOnTarget(11, plr)
end
end
end

so if he cant get a random player he'll cast a another spell?

[stoneharry]

First question, you can make it do this command,

local target = pUnit:GetTarget()
if target:IsCreature() == true then
else

and do your stuff in there.

For your second question:

local plr = pUnit:GetRandomPlayer(0) -- we say plr is a random player
if plr == nil -- If the player is equel to nil (means if it is nothing
else - else if it is something
pUnitoStuff

Hope this answers your questions.

[Ascelyn]

Where about should I add the

local target = pUnit:GetTarget()
if target:IsCreature() == true then
else

and what to I type following?
function_x(Unit, Event)
pUnit: bla bla? or something else?

Sorry i'm not good at LUA Tried many guides..

"So there's no possibility that you can script it so it attacks both players and other creatures?"

X in maths is usually something that you need to find / change / define, for example the classic:



So I tend to use that a lot in examples.
This is how it would answer your question:

function x(pUnit, Event)

x can be whatever you want it to be, so for example

function Check_If_He_Is_A_Creature_And_Do_Something(pUnit, Event)

Long name but you get the idea, so now I want to do something depending on whether it's a creature or a player.

function x(pUnit, Event) -- Note here, were using pUnit, NOT unit or Unit.
    local target = pUnit:GetTarget() -- Get who were targeting
    if target == nil then -- Is there nobody there?
    else -- There is somone here
         if target:IsCreature() == true
         pUnit:FullCastSpellOnTarget(11, hostile) -- I talked about defining hostile in a post earlier on, 11 is the spell id
         else -- He's not a creature
         pUnit:FullCastSpellOnTarget(11, pUnit:GetRandomPlayer(0)) -- He's not a creature so cast on the player
          end
     end
end
