Need a help with [Offline] Elsword (LUA related)

Noob here! Don't worry, I'm not tooooo slow.
I got through some stuff on my own by reading the old threads here but reached a point where I might need help. Nothing too nefarious, just on the offline client. Easy, right? I'm not sure, I'm struggling with editing the .Lua files. and can use some advice.

• Nothing too big, just want to know how to get it lua files working without crashing the game. I use EWCryptTool.exe and am able to get the files through ludic (unless it seems to change the lua, which becomes a problem.), but once I recompile it (through) luac and re-encrypt. the file simply just doesn't want to work, or the client simply doesn't recognize it. I don't use Ernilos' ElswordLuaEditor because despite everything I do, it just doesn't seem to work and I'm left with a blank screen
  
• So far I'm trying to work on PreTestUnit.lua and RAVEN_FIGHTER.lua in the data003.kom extractions.
  
• I'm messing with some very old stuff, so if you know on how to fix this, I'll give you many thanks.

Specifically, I will take a .lua file and bring it to the folder where EWcryption is at then use a Bat file to get to work.

Quote:

EWCryptTool.exe -e RAVEN_FIGHTER.dec RAVEN_FIGHTER.lua

Then I would take the decrypted file and toss it into luadec or luadec.metaworm.site if that doesn't work.

Luadec RAVEN_FIGHTER.dec > RAVEN_FIGHTER.lua

(This will often create an empty Lua file. so I often find myself tossing it in Luadec.metaworm.site since it does 5.1 decompiling then take that to my folder to continue the next step)

Luac works strangely enough and recompiles the decompiled RAVEN_FIGHTER.lua into a RAVEN_FIGHTER.dec.

(Remember what I said about taking the lua out of its directory into the directory where my decryption and decompiles at in? Turns out that it changes the file name within the lua being compiled and decrypted again as I've noticed.

The recompiled RAVEN_FIGHTER.dec's top text:

Quote:

LuaQ   @RAVEN_FIGHTER.lua 4‹8

The original RAVEN_FIGHT.dec's top text.:

Quote:

LuaQ  V @E:\hudson\jobs\ES_JP_SINGLE_CLIENT\workspace\reso urce\Script\Major\RAVEN_FIGHTER.lua 4‹8

I don't know if that plays a key role or not, but I pretty much hit a wall here, and idk if this is the cause of my headaches. I'm not an expert in any of this, and I'm going in this blind, so if someone can lead me in the right direction, I will greatly appreciate it.

I checked the Chinese forums but can't get it to not crash.

(The offline trial version, shouldn't be too different from the standard game at the year of its release. I've seen a handful of people able to get their modding going despite those required changing the lua files. )

problem solved~

From the last line I guess you figured it out, but in the case that you didn't: the steps to modify the LUAs from original KOM to modified KOM in the offline demos is the following:

1. Unpack the KOM file (Any public non restrictive KOM V3 algo 0 extractor, kompack or Kurisutaru's extractor)
2. (For .txt/.lua extensions) XOR the content with xorkey= [0x02,0xAA,0xF8,0xC6, 0xDC,0xAB,0x47,0x26, 0xEF,0xBB,0x00,0x98] (thats what EWCryptTool does)
3. Decompile the LUA file in question (luadec51 -> consider that this is not always accurate and may result in incorrect lua code, making the game crash, it's better if you decompile files one-by-one to see if they work)
4. Modify your LUA file (Text Editor)
5. Compile the LUA file again (luac from a lua51 build), overwriting the extracted .lua's filename
6. XOR the file again (EWCryptTool)
7. Pack the kom folder back (Any public non restrictive KOM V3 algo 0 extractor, kompack or Kurisutaru's extractor)

Remember that none of these steps work past 2014 KOM versions, as methods have changed.

I struggled the most with getting the NewSkillTemplet.lua working but I managed to do it entirely manually with unluac (Which was a huge gamble). I checked to see if any of the codes were off for the LUA, like not all of it is decompiled, but I said "fuck it", and used that one instead, recompiled it, and encrypted it. And it worked like a charm. I believe it was the Japanese text being messed up which scared me, but looks like the text, desc, and names seem to retain it's normal functions despite not being decompiled. the other Luac decompiler and the online one I tried gave me a headache.

I have 2014 client files that have the non-encrypted LUAs in their resource folders. I examine them and try to translate them into readable files for offline clients. I don't exactly dump them in there but use them as a reference for what skills I want to add and edit since they are more neatly organized than the offline TW/JP client.

Even though they mostly come out blank, Ernilos' ElswordLuaEditor can, at times, compile and encrypt the LUA I open; I just have to use an LUA editing software to actually do the editing and paste it in the editor to skip the re-compile and encryption process. Works like a charm.

Before I invest in this area I think it's smart to ask; Does the DirectX files, texture files, and motion files from 2014 and above koms (v3 and v4 and up) work if I install them in the offline kom folder I'm going to compact back into kom? Like replacing older .X files with newer ones?

I did this with the Ogg sound files, and it worked, are those also safe to use?

DirectX files will work, but if the model/motion file relies on KSM format it likely has changed slightly throughout the years, meaning they probably won't work. You can check if its a xof (directx model file) or KSM (kog skin mesh) file by inspecting the first 3 symbols of the file by using a hex editor, like ImHex.
Textures and the like haven't changed too.

I'm kinda scratching my head rn, I opened up the LUA for Skillset and Ara's Lua (2014 already translated and decompiled). I see a lot of base.x and .y files for her skill in her respective Kom, but not ALH_SWALLOW_ASSAULT_BASE.Y. It seems even in the official client side, which I extracted her from kom132, 131, and 130 that is actually missing even though it's part of her crucial skill (SWALLOW_ASSAULT is her Flying Kite skill.). I was successful with the changes of Sword Wave but not Triple Geyser and Hypersonic Stab (same Problem):confused:

So are the Lua's and MajorMesh.txt just lying, or am I looking in the wrong direction? I checked the Major Mesh from the the offline version, and it's the same for Triple Geyser, nowhere to be seen.

The file below is from 2014.

I can't find some of the dummy boxes of certain skills. and I can't find anything for triple geyser or Flying Kite (Swallow Assault) despite the Major Mesh having their file name listed. Which has been bugging me.

It's very likely that these files are residing in data002 (non-offline versions). I have found Effect_ElSword_FlameGager.x to be in there at least. For old or animation-state-dependant attacks you will not find sufficient LUA data to understand linkage between which state does what effects, which means you'll have to do guess work, or reverse the leak from ages ago

Thanks, I'll use your Kom extractor to speed through this process since I'm now looking for .x and .y files right now to replace old skills.

EDIT: I do recall string states under a lot of skills. Does this require SQL knowledge?

I'll see what I can do

Hello, Can I ask if you still have client and server 2014 files ?

Thanks

Go to youtube and Search for Elsword offline Server (PGaming Channel).

I do, in fact. While I have successfully decompiled the offline one, it's going to take some time before I can do anything with either. It's a pain setting the server up, so I want to do a convenient workaround. The problem for me is parsing it, which I see varying success with. Requires VS2003 for a better result. I've been moving at a snail's pace as of late, so I wouldn't get my hopes up.
