How do I make a new LUA work?

[Akisunmaaji]

I'm a complete noob with LUA and I can't for the life of me figure out how to get this LUA file to work for my server..I made a LUA file and put it in the scripts folder but I don't know how else to make it work..I've searched for like an hour now and I can't find anything. Any help is appreciated.

Hi,

At first, what is this for a LUA file? Post it here

Did you enable LUA in the arcemu-world.config?

Is it in the right script folder? /ArcEmuXXXX/scripts ?

Well it's kinda confusing the way it's written in the config file, but here is what mine says and maybe you can tell me what to change:

#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#
# Scripting Engine Setup
#
#    ArcEmu can support multiple script backends via the means of loading .dll files for them.
#    This section in the config can enable/disable those backends.
#
#    LUA
#         If you would like to enable the LUA scripting backend, enable this.
#         Default: 0

<ScriptBackends LUA="1"
                AS="1">

And yes, I'm sure the lua file is in the right folder.

And here's the link to the LUA script: http://www.mmowned.com/forums/emulat...-boss-lua.html

It appears that you got Lua enabled, you should look for errors when starting up 'world' that's the only way for debugging Lua. And if you find some errors at start up post them here.

Well is that all I have to do to make it work? Put it in the file and have LUA enabled? I thought I was supposed to use some kind of sql file to inject it into my world database, the only problem is I don't know how to do that.

Well it seems, if you want the 'RickAstley' script to work you must replace

RegisterUnitEvent(CreatureEntryIDHere, 1, "RickAstley_OnCombat")
RegisterUnitEvent(CreatureEntryIDHere, 2, "RickAstley_OnLeaveCombat")
RegisterUnitEvent(CreatureEntryIDHere, 4, "RickAstley_OnDied")

the CreatureEntryIDHere, with the ID of the npc you want to use for it.

Ah, thanks. However that just created a new bigger problem for me..

So I tried to login after restarting my server with the modified script in there, and all of my characters are stripped of their clothes and "Login Failed" every single time. I took the LUA script out and it is still doing this..what could have caused this?

[TheZaronz]

This can't be causing that, it probably comes from an issue in the char DB, did you upgrade revision or anything?

No. I was literally just playing with a friend, modified the script, shut down my arcemu-world.exe, restarted it and the shit hit the fan.

Maybe you change some configs?

And to locate your LUA error

you can see can see it in the arcemu-world.exe like TheZaronz said.

Rename the script and put a 'Z' infornt of the Filename, so when the server starts you can see the script when you scroll a little bit up.

go to world.conf and change this

                AS="1">

And than put your LUA in the scripts folder. Now all you do is add the sql and restart the server

Hope it helped

He did it already, look at his first post xD

LUA scripts have nothing to do with characters showing up naked or causing login errors. You must have edited the database. There is no other reason why that could have happened by just editing a lua script.
