Lua script loaded but no change in game

[Gix85]

Hi, I'm new in Lua and wow repacks in general. A friend of mine installed a Pendregon's repack on his notebook, we put on a network in hamachi and i'm having fun with debugging.

I was trying to fix a bug in darkweaver syth in settek halls. He's not spawning elementals. I've corrected the script in lua file and sent it to my friend that loaded it in the server. He says that the console tells him that the load has been succesfull, but we don't see any change in darkweaver syth.


Any ideas Oo?

And by the way, it's correct to fix boss bugs with lua scripting? There are any tutorials to help me improve?

A script error not poping up doesn't mean you script it correct, just means the script is not wrong. The script being wrong and the script not working like it should are 2 different things.

Being a completely noob with scripts, i've done some tests to try out if the script is wrong or is not loaded u.u, i'll show.

This is the first part of the darkweaver syth lua:

local NPCID = 18472
local randomtextOC = math.random(1,3)
local randomtextOKT = math.random(1,2)

function Syth_OnCombat(Unit, Event)
if randomtextOC==1 then
Unit:PlaySoundToSet(10503)
Unit:SendChatMessage(14, 0, "Hrrmm.. Time to.. hrrm.. make my move")
if radonmtextOC==2 then
Unit:PlaySoundToSet(10504)
Unit:SendChatMessage(14, 0, "Nice pets..hrm.. Yes!")
if randomtextOC==3 then
Unit:PlaySoundToSet(10505)
Unit:SendChatMessage(14, 0, "Nice pets have.. weapons. No so..squawk..nice")
end
end
end
unit:RegisterEvent("Syth_HealthCheckA", 1000, 1) -- Those 3 lines impose the boss to summon adds at some health checks --
unit:RegisterEvent("Syth_HealthCheckB", 1000, 1)
unit:RegisterEvent("Syth_HealthCheckC", 1000, 1)
unit:RegisterEvent("Syth_Frost", 10000, 0)
unit:RegisterEvent("Syth_Flame", 15000, 0)
unit:RegisterEvent("Syth_Shadow", 21000, 0)
unit:RegisterEvent("Syth_Arcane", 26000, 0)
unit:RegisterEvent("Syth_Chain", 29000, 0)
end

Now, to try if it has been loaded, i've put a -- to comment the 3 lines that check syth's health and causes the summons. Well, we have loaded it, the console check told that the lua file was ok and load succesfull, but syth tried to summon the elementals (he yells and cast the spell, but the elementals don't come out). Don't you think that, if the lua file was Really loaded, he should simply attack without trying a summon? Man i hope you can understand me, it's about 5 years i don't write in english XD...

The spell isn't scripted in the DB in ArcEmu, to go around this, make the script spawn the Adds instead.

[BanzBoyz77]

That's what I'm scripting for him now but I can't figure out how the script reads Darkweaver's health if it doesn't specify it in here. All it is is a registered hook with no specific health to check for.

local Random_Xx = math.random(1,3)

function Syth_OnEnterCombat(Unit, Event)
	if Random_Xx==1 then
		Unit:PlaySoundToSet(10503)
		Unit:SendChatMessage(14, 0, "Hrrmm.. Time to.. hrrm.. make my move")
	end
	if Random_Xx==2 then
		Unit:PlaySoundToSet(10504)
		Unit:SendChatMessage(14, 0, "Nice pets..hrm.. Yes!")
	end
	if Random_Xx==3 then
		Unit:PlaySoundToSet(10505)
		Unit:SendChatMessage(14, 0, "Nice pets have.. weapons. No so..squawk..nice")
	end
	Unit:RegisterEvent("Checkhealth_zz", 1000, 0)
end

function Syth_Phase2(Unit, Event)
	Unit:RemoveEvents()
	Unit:RegisterEvent("Checkhealth_zyz", 1000, 0)
end

function Syth_Phase3(Unit, Event)
	Unit:RemoveEvents()
	Unit:RegisterEvent("Checkhealth_xyz", 1000, 0)
end

function Syth_Phase4(Unit, Event)
	Unit:RemoveEvents()
end

function Checkhealth_zz(Unit, Event)
	if Unit:GetHealthPct() =< 70 then
		Unit:SpawnCreature(**<Creature ID Here>**, Unit:GetX(), Unit:GetY(), Unit:GetZ(), Unit:GetO(), 14, 150000)
		Unit:RegisterEvent("Syth_Phase2", 1000, 1)
	end
end

function Checkhealth_zyz(Unit, Event)
	if Unit:GetHealthPct() =< 50 then
		Unit:SpawnCreature(**<Creature ID Here>**, Unit:GetX(), Unit:GetY(), Unit:GetZ(), Unit:GetO(), 14, 150000)
		Unit:RegisterEvent("Syth_Phase3", 1000, 1)
	end
end

function Checkhealth_xyz(Unit, Event)
	if Unit:GetHealthPct() =< 20 then
		Unit:SpawnCreature(**<Creature ID Here>**, Unit:GetX(), Unit:GetY(), Unit:GetZ(), Unit:GetO(), 14, 150000)
		Unit:RegisterEvent("Syth_Phase4", 1000, 1)
	end
end

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

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

RegisterUnitEvent(18472, 1,"Syth_OnEnterCombat")
RegisterUnitEvent(18472, 2,"Syth_OnLeaveCombat")
RegisterUnitEvent(18472, 4,"Syth_OnDeath")

Whipped this up real quick, might not work, let me know how you get on, no spells or whatever so you can fill them in.

Thanks for help. Just tried this one. As usual, ArcEmu server says that the lua is good, but when we summon syth he doesn't seem changed at all. I'm wondering why... I mean, even if i change the yells in the lua, the speech doesn't change at all. Is like the lua is completely ignored and we can't explain why...

The boss is already scripted if you compiled with scripts I think. To bypass this create another npc with a different Id and bind the script to the new NPC, you'll have to change the loot IDs if you want the correct loot though

[Gix85]

Let me understand, if the boss is already scripted there's no way to change it? the only way is to create another scripted ncp?

[Facerolling]

There is a way to exclude it from the ArcScripts if you have a poke around in the source files, but if it's a repack then yes, that's the only way.

Ok. So we misunderstood everything about the private servers. Can you explain me the procedures? I mean, not how to do (I suppose it would take ages to write it down in a single post), but WHAT we have to do, we can find tutorials if we know what to do.
We want a server where we are capable of correct boss bugs with lua scripts, is it possible? what are the usual ways to do that? I gave a look at the various tutorials in this and other sites, they all explain how to do something, not why. We didn't understand if we need to compile a server from the source code everytime we fix a bug (and if we have to fix the bug modifying the source code). It would make sense, all the saved data are stored in a database so when we compile and start it, no one will notice the difference. Am I right?
