[ULTIMATE] Lua Guide & Tutorial

[-Jebus Fist-]

Extreme bumpage.

[~Keric Vi Britannia~]

This thread does need some epic bumpage... It's one of the most fluent, well-thought, written out, and explained guides I have seen. Not compared to those crappy "How to script a boss!" guides, which are oh so horrible, even if done by a high ranking person on MMOwned. I'm still re-reading this for the fifth time, to try and learn Lua on my own. x) I still need help though..

[shadowstep0705]

i got a question: can i use a flag a text message, like when i type something in, the script will get activated

[WargRider]

When your doing the part with the teleporting only GMS, I dont know if this works with LUA but I am pro C so instead of all the elseifs, try something like

elseif(playername != "GM n1" && playername != "GM n2") then

the && signifies an "and" statement instead of all the ifs, so basically what your syaing if the player here is NOT a GM and if you want ONLY gms, then based on the name change the && to || which is an "or" statement and change the != to == which is obvious what it means . IK if ti will work or not I dont really script too much in LUA but it might work give it a try.

but seriously stop with the LUA tuts.

[digger514]

Well, First off all it would be nice if you was to put it into [code] boxes, but none the less i will help you out, what you have done is placed a " " after each of the commands, which in call is probably not making them be called to work. So let me fix it up for you!

function Deathwing_OnCombat(Unit, Event)
    Unit:SendChatMessage(12, 0, "You will burn by the fires of the Black Dragon Flight!")
    Unit:RegisterEvent("Deathwing_Boulder", 5000, 5)
    Unit:RegisterEvent("Deathwing_Armageddon", 10000, 0)
end

function Deathwing_Boulder(Unit, Event)
    Unit:CastSpellOnTarget(59732, Unit:GetRandomPlayer (0))
end

function Deathwing_Armageddon(Unit, Event)
    Unit:CastSpell(45915)
end

function Deathwing_OnDied(Unit, Event)
    Unit:SendChatMessage(12, 0, "No........This cannot be.....I promise all of you will burn!")
    Unit:RemoveEvents()
end

function Deathwing_OnKilledTarget(Unit, Event)
    Unit:SendChatMessage(12, 0, "HAHAHAHA. Yet another incinerated soul!")
end

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

RegisterUnitEvent(50, 1, "Deathwing_OnCombat")
RegisterUnitEvent(50, 4, "Deathwing_OnDied")
RegisterUnitEvent(50, 3, "Deathwing_OnKilledTarget")
RegisterUnitEvent(50, 2, "Deathwing_OnLeaveCombat")

Now that is just from what i can quickly see, there seems to be no noticable errors so try that one. Thanks for posting

EDIT:Aha even noticed another one, you have a mix of "pUnit" and "Unit", which im guessing could also be clashing, and the fact you are sometimes calling on "Unit" and using "pUnit" instead. So, One sec ill fix it again.

There you go, that one should work.

[xgamer08]

ok ive fixed wat u said was wrong but it still isnt working. ive tried making the id my entry id and the npc that i used id but neither of them works. any ideas?

[-Jebus Fist-]

I found a "error".
Here you state this:

Unit:SendChatMessage(language, channeltype, "Message")

However, here, you clearly ment to broadcast a message in universal, but you put it wrong.

Unit:SendChatMessage(41, 0, "Creature begins to transform!, and his minion appears!")
