Hello and welcome to the new and improved guide to lua. I will split this into parts to make it easier to understand. This Guide uses color coding on a lot of the text just so you can see What is what.
1. understanding lua as a whole 2. Registering the events 3. the events themselves 4. registering events inside events 5. Tables 6. Pre-made lua scripts 7. Portal making 101 8. key points of new guide
Understanding LUA as a whole
LUA is much more then just world of warcraft it is the base of many games. For this Instance we will be just looking at Lua on wow because it would just be easier that Way and less time consuming. First off there are two main parts of lua The part that registers the event found at the bottom and the part that IS The event. The part that registers the event MUST be at the bottom of the script And must be the same name as the event itself. The event should always begain With the same name as the register.
Registering the events The events I have listed are here for your Convenience. All you have to do is change The “Npc spawn ID” to the id that spawns The npc you want this script for As well as The “Name” Needs to be changed to the name of the creature. This part of the LUA Must be placed at the bottom.
☼RegisterUnitEvent (Npc Spawn ID, 1, "Name_Entercombat") Using this will make the event happen when the player enters combat with the Npc that has this script enabled.
☼RegisterUnitEvent (Npc Spawn ID, 2, "Name_Leavecombat") Using this will make the event happen when the player leaves combat with the Npc that has this script enabled.
☼RegisterUnitEvent(Npc Spawn ID, 3, "Name_Killtarget") Using this will make the event happen when the Npc who has this script kills its target
☼RegisterUnitEvent (Npc Spawn ID, 4, "Name_Died")This event will happen when the npc has died
☼RegisterUnitEvent (Npc Spawn ID, 10, "Name_playerenter")This will happen when player reachs waypoint.
---note you will need at least one per event you would like to do so if you wanted to make the npc do something on waypoint AND combat you would need to make two making the bottom look like this

Changing the red to what you need
Spell-this can be found on thottbot or Wowhead it’s the last numbers of the page of spell Type-use the premade table I have made below Language-use the premade table I have made below Scale-this is how big you want it to get by multiplying it Modelid-this is the display id of the mob Flag-this can be found on mmowned Value-% at wich you would like the npc’s health Momenttype-you can pick fly or walk Soundid-you can find on mmowned Entryid- this is the same as the number used to spawn it Duration-how long until this is undone Faction- what faction would you like it Message-enter your message here X,Y,Z,O- these are found by typing .gps inside the server itself at the location you want.] Emoteid- The id of the emote search mmowned for these Displayid- display id of what you want it to look like Time- Time is in milliseconds
The Advanced if commands Use these commands if you want Whatever is between the then and the end Tags to work only when it is a yes.
☼pMisc:GetName() This will return the units name [Returns name if true does commands]
☼pMisc:GetX() This will return the units X position. [to be used later in codes]

☼pMisc:GetZ() This will return the units Z position. [to be used in later codes]
☼pMisc:GetO() This will return the units orientation. [used later in code]

Registering events inside events
RegisterUnitEvent(225501, 1, "Vanity_OnCombat") Is to register the event itself but if you wanted to make Events inside an event you would use Unit:RegisterEvent("Vanity_Phase1",1000, 0) And then for the sub event you would use function Vanity_Phase1(Unit, event)lets put them all together to show you what I mean. Hope this helps out people wondering about two part events.
---code---- function Vanity_Phase1(Unit, event) if Unit:GetHealthPct() < 95 then Unit:RemoveEvents() Unit:SendChatMessage(11, 0, "You think you can beat me") Unit:RegisterEvent("Vanity_Phase2",1000, 0) end end
function Vanity_Phase2(Unit, event) if Unit:GetHealthPct() < 80 then Unit:RemoveEvents() Unit:CastSpell(22436) end end
function Vanity_OnCombat(Unit, event) Unit:SendChatMessage(11, 0, "Do i have to kill you are no equal?") Unit:RegisterEvent("Vanity_Phase1",1000, 0) Unit:RegisterEvent("Vanity_Phase2",1000, 0) end
I have made a few pre made’s for you guys to take a look at All of these are based on using the grubish arena as the home Of the npc boss or portal just change whats in red to the id of your Mob you want this on.
Making a portal is not far from Making npc lua scripts just different commands You will want to change everything in red to what You need for yourself. (Note I tell how to make the sorry) Script for the portal not the portal itself
----code---- function Teleporting_onUse (pUnit, Event, pMisc) pMisc:Teleport (MAPID, X, Y, Z) end
“PORTALGUID” is the number used to spawn it “MAPID, X, Y, Z” can be found by typing .gps in gameThis new guide is to help people understand lua and how to use it the edit notes are as follows
-color coding -lua for dummys -Portal script -registering an event in event -lots more just look -removed the scripts becasue too long
---for example codes go to shadowcast.midgard-wow.com that is where all my work gets put
um i dont member how i got them all but most of them are from searching thrugh scripts or finding a few new ones here or there i cleared it all up and tossed it into a guide imm edit this one tho instead of the other one
GetX, GetY etc are mostly used for spawning mobs when mob, for example, dies. GetX gets X for mob, GetY gets Y, etc, then it spawns the mob at excactly same place as the dying mob.
Fix that ^^
I have read this and it seemed good at first, but at the end it looked like you were doing something completely different than what you explained at the top. The way you explained that is pretty confusing to me and I don't really get any of this. This has left me extremely frustrated and gave me a head ache. Thanks for trying to contribute though.
Remember, there's no such thing as a stupid question, just stupid people!
function Anzu_HealthCheckA(Unit)
if Unit:GetHealthPct() < 66 and Didthat == 0 then
x = Unit:GetX()
y = Unit:GetY()
z = Unit:GetZ()
Unit:SpawnCreature(519203, x, y, z, 0, 17, 60000);
Unit:SpawnCreature(519203, x, y, z, 0, 17, 60000);
Didthat = 1
else
end
end
function Anzu_HealthCheckB(Unit)
if Unit:GetHealthPct() < 33 and Didthat == 1 then
Unit:FullCastSpell(14204)
x = Unit:GetX()
y = Unit:GetY()
z = Unit:GetZ()
Unit:SpawnCreature(519203, x, y, z, 0, 17, 60000);
Unit:SpawnCreature(519203, x, y, z, 0, 17, 60000);
Didthat = 2
else
end
end
function Anzu(unit, event, miscunit, misc)
print "Anzu"
unit:RegisterEvent("Anzu_HealthCheckA",1000,0)
unit:RegisterEvent("Anzu_HealthCheckB",1000,0)
end
function Speak_OnCombat(Unit, Event)
Unit:SendChatMessage(11, 0, "You Dare Defile Me?!?!")
end
LUA mega scripting!!
when I can! This deserves a bookmark!
