What LUA Really is

**LiLLeCarl** · 21-09-09, 05:22 PM

Hello MMOPro

Today we are going to talk about what LUA really is,
Well in short i can say its a file extension that cant do anything with the OS.

In the emulator that have LUA support its a little file called "LUAEngine.dll" or something like that.
That engine reads thought all the LUA files you have in your LUA folder, and that means you don't need to compile them or something.
Thats both good and bad it there ways.

GOOD:

Its way faster and easier to edit cause the core don't allocate them so they are probably loaded to the memory.
They are simpler to understand.

BAD:

You don't know if your modifications is right, it can be a typo you dont see before the LUAEngine reads the file(when your starting the server again).
They are loaded to the memory so all the 4000 billion blizzlike LUA's will take more RAM to the server.
The engine will handle so much data so it might start crashing or peaking memory/processor time as a blue donkey (or as ArcEmu)

REALLY BAD:

The emulation wont continue!
All people say "LUA is enough for me"
That means?
No new people will learn C++ and help improve the cores.
I think LUA is evil from the beginning it makes all N00b's say i'm skilled, :O why did my core crash!
Just download the Visual Studio and start testing you will learn the basic stuff you can do in LUA faster then you think AND A LOT MORE

thats my opinion

By the way i'm not 100% sure on that the LUAEngine loads all LUA scripts to the memory but i think so.
Please feedback on that part else i'm 100% sure

Same, I use humans for mine..

i do agree. though........mangos/trinity have their sh!t together as far as scripts and what not being C++....be nice if arcemu would incorporate that to. its so much easier to compile a C++ script then troubleshoot 2500+ lua files...

Your right in the most ways ^^, the only problem is ArcEmu isnt good anywhere ;D use Aspire and port the FEW good commits from arc to aspire and you will have a good core (Yaay 4 LilleCarl)

even despite the fact i hate arcemu....cuz they are so slow. but K-mod Arcemu isnt doing to bad...

let s go on topic and start talking about how bad LUA is ?

Its is not bad for fast edits and I think that is what it was meant for when people made wow lua compatible but i think we have taken it too far in that we use it now for advanced scripts that people should be making in c++ not lua. I myself was a violator of this but now I see what harm it can do both to the continue of programing and the server iteself
