Lua issues

[Evilbuffy]

God Day People! There is a lot of threads regarding issues with Lua. For some reason many Lua scripts are not loading / working as they should, and I'm having the same problems. Is there anyone who could mention all the known "bugs" that cause the issues with Lua?

This is the script I'm going to talk about at the moment, but I also have trouble getting Blizzlike scripts to work too.

I doubt there is anything wrong with the script I'm trying to use, but for some reason something is doing so when I spawn the NPC (with the entry ID 100255) it's not showing the menus. I also have over 1000 Blizzlike Lua scripts, and they some of those don't want to work either.

And of course I have enabled the Lua scripting in my config files:

I'll look through the script when I get on my pc in 30-60mins (unless somone posts first) but I read the text and issues with Lua is generally:
A: People just don't understand the theory, when to remove events etc
B: There using the default Lua engine which practicly never works.

I've only had 1 error before involving the actual Lua possibilities and that is that you cant register something in a gossip or on death.

[Evilbuffy]

Okey, Thanks for helping out here.

A: I'm not a "God" in scripting, so I may have done something wrong.
B: We are using the default Lua engine, because our Core Dev says that we can't change it.(which is bull****).

You forgot to end the Gossip_Submenus function end anyway fixed it 4 ya

The second "end" which you added, is what you mean I'm missing?
I will test this out, just need to wait for the owner to come online.
And if it works, I deeply apriciate it.

[Scubast3ve]

Thats it ^^ enjoy

[Evilbuffy]

Okey, Thanks. I will try it out, but still post stuff about the Lua engine here. Since I know the Lua engine causes a lot of issues and stuff.

[Scubast3ve]

kk main issues include:

- Not ending functions or ifs
- Leaving out brackets or commas
- Capital letters(it is all case sensitive so be careful)

if i think of anymore i will post em

[stoneharry]

I'm telling you it's the core. Take a script that uses a lot of commands from the release section, then use it with the default engine, then compile the GuaEngine for example and try again. You will find a huge difference. I've already fixed 2 people's problems today and it was because there Lua engine did not support the stuff they wanted to do. Also +Rep to Scubast3ve for helping before I got back

[Scubast3ve]

In this case its not the core but yes i agree people who dig up old lua scripts only end up in here trying to use lua instead of lua++

[Zudrik]

I've encountered a bug which made me hold off on my project with scripting 'The Light of Dawn' quest for Death Knights. Using the default Lua engine.

Same Npc, say it's ID is like 12975. You can define it (ThisGuy = 0) and make it so if you have the same creature (saying that there are 2 spawned) they each do something different.

It would be something like:
The function
ThisGuy = ThisGuy +1
if ThisGuy == 1 then
blah blah blah
if ThisGuy == 2 then
blah blah blah

And it keeps on going.

Now what I was doing was having this creature move with waypoint, and I had them set to destroy their waypoint map when they got to a certain area. All was working fine, however, until I had 17 of the same creature moving. So once creature 17 made it to that waypoint and destroyed their custom map, it would crash the world.exe.

I am seriously clueless about this, but I would call it a bug.

[Gastricpenguin]

Use my engine, it's way easier than lua++ :P
