Blackheats LUA Guide 1.0

-----|Forewords|----------------------
Greetings! It's nice to have you here.
Grap a cup of tea, pull up a chair and listen to what I have to say...

--------------------------|Contents|-----
Today we're learning basics.

Table of Contents
1.1- Introducing LUA
1.2- Simple boss script
1.3- Numbers Used

------|Introducing LUA|------
Lua is a script languange which is most known within World of Warcraft.
World of Warcraft AddOns is scripted with LUA etc.
Then what does this have anything to do with "Script a simple boss"?

LUA Is also used for scripting bosses at World of Warcraft "private" servers.
You'll hopefully get it soon :-)

------|Simple boss script|------
Alright, let's start with your first script!
This is going to be exciting right?! If not, you should be here. Before we start I have another thing to say. If you're not intrested in scripting etc etc then it's 50% Harder to learn anything.

Alright, I am going to start showing you the complete script (Please note: This script is only for educational purposes, it's not a show of or anything)

 
function BossName_NowTalk(Unit, Event)
Unit:SendChatMessage(Type, Language, "Boss talk/yell Message!")
end

RegisterUnitEvent(NpcID, When, "BossName_NowTalk")

Alright, there you have it. All the fields marked with yellow color is the fields that you edit.

We'll start from up to down..

BossName_NowTalk

"BossName" Is where you put your NPC/Boss name, it's up to you!
"NowTalk" Can the be the phase of the boss or just a note to know when.

Type, Language, "Boss talk/yell Message!"

Type: For example this can be: Yell, Say, Whisper, etc etc. The exact numbers for this, scroll down.
Language: Is the language you want the creature to talk. Numbers are also below.
"Boss talk/yell Message!": PLEASE NOTE: The message must be inside of two of theese " ".
Simply put the message you want the creature to say / yell.

NpcID, When, "BossName_NowTalk"

NpcID: Here you put the ID Of the creature, this binds the script to the creature.
When: This is when you want the script to react. Example, when the player(s) enter range, when the creature engages in combat etc etc. Numbers below.
BossName_NowTalk: This must be the same as

function BossName_NowTalk(Unit, Event)

Now, lets review the other part of the script, the noneditable.

function BossName_NowTalk(Unit, Event)

Unit:SendChatMessage(Type, Language, "Boss talk/yell Message!")
end

The ones marked with red MUST always be there, no matter what.
function, always in start and end always in the end.
Same goes for the Unit, Event.

What about Unit:SendChatMessage ?
This is a command which commands the unit to perform a action.
You can also switch this out with other commands such as:
Unit:CastSpell(Spellid)

When you're done with your script, save it as "Boss_Name.lua" and you must have LUA enabled at your server.

P.S. LUA Scripts are case sensetive!

Thank you for this time, more coming up!

A few questions.

1) I see that you split the code boxes sometimes. Will these be seperate files, or the same file just a different line?
2) We can just type these in notepad right?

Thanks, and +rep for the great guide!

2) We can just type these in notepad right?

@ 1): This is a bug which comes when I copy all my text.
A whole script:

function PhaseorFunction_NPCname(Unit, Event)
Unit:SendChatMessage(14, 0, "message")
end

RegisterUnitEvent(NPCID, When, "PhaseorFunction_NPCname")

Sometimes in this guide it's different only different lines..
Its not different lines when I explain, but when you see the script as a whole.

@ 2): Yes. Aslong as you save them as a lua file.

Alright, thanks!

[knaur]

nice one +4 rep

[Azshaz]

Where do I put it after its made? It doesn't work if I put it in script_bin

[Vindicated]

Nice to see you contributing. +Rep x2

[knaur]

Where do I put it after its made? It doesn't work if I put it in script_bin

hehe it shall be in your scripts folder not script_bin lol

[Azshaz]

hehe it shall be in your scripts folder not script_bin lol

Don't see a scripts folder :<

Could it be perhaps I'm using an older repack? I'm using a 2.4.3 repack. Or should I just make the folder?

[mineo117]

the reason you have not scripts folder is because you are using a repack. I personally do not advice you to use a repack rather you should compile server from the base source code. If you do not wish to start from scratch then you can simply just make a new folder in the root directory of your server folder called scripts and put your .lua files in there. I hope this helps you. +Rep for this guide not as detailed as i would have like but this is not a classroom either so great job.

[P1raten]
