Lua decompiler (mostly) FIXED - .luac files ready for your viewing pleasure!

[LordChatalot]

So, I downloaded lua 5.1 sources, cygwin and luadec 5.1. Then I got the text of build_luadec and declared the file as .exe (I don't know how I should download it in github). I have no experience with cygwin, so how should I run with it build_luadec? (And thanks that you spend so much time for me)

Or do you have still the 7z Archive with the decompilation results?
In that case, my email is: order_of_shadows@gmx.de

Anyone tried that on Total War .luac files?

LUAC is not a single format like JAR, it has a lot of variants for every app, and Total War's uses some custom settings for sure.

It seems to work:

I tried it with template_attrition_entry.luac from Shogun 2:

local this = UIComponent(Address)
local utils = require("utilities")
local m_pos_x, m_pos_y
local shane_output = false
function ShaneOutput(msg)
  if defined.debug and shane_output then
    out.shane(msg)
  end
end
function Initialise(details, type_a_bg)
  ShaneOutput("** attrition_entry:Initialise **")
  if type_a_bg then
    this:SetState("A_normal")
  else
    this:SetState("B_normal")
  end
  UIComponent(this:Find("dy_name")):SetStateText(details.CharacterName)
  if details.MenLost ~= nil then
    UIComponent(this:Find("men_lost_dy")):SetStateText(CampaignUI.LocalisationString("player_stats_men_lost") .. ": " .. details.MenLost)
  elseif details.Region ~= nil then
    UIComponent(this:Find("men_lost_dy")):SetStateText(details.Region)
  else
    UIComponent(this:Find("men_lost_dy")):SetVisible(false)
  end
  m_pos_x = details.PosX
  m_pos_y = details.PosY
  if details.PortraitPath ~= nil and #details.PortraitPath > 0 then
    image = UIImage(details.PortraitPath)
    image:SetComponentTexture(this:Find("image"), 0)
    UIComponent(this:Find("portrait_clip")):SetVisible(true)
    UIComponent(this:Find("unit_frame")):SetVisible(true)
    UIComponent(this:Find("icon_raiding")):SetVisible(false)
    UIComponent(this:Find("building_window")):SetVisible(false)
  elseif details.BuildingImage ~= nil and 0 < #details.BuildingImage then
    image = UIImage(details.BuildingImage)
    image:SetComponentTexture(this:Find("building_window"), 0)
    UIComponent(this:Find("portrait_clip")):SetVisible(false)
    UIComponent(this:Find("unit_frame")):SetVisible(false)
    UIComponent(this:Find("icon_raiding")):SetVisible(false)
    UIComponent(this:Find("building_window")):SetVisible(true)
  else
    UIComponent(this:Find("portrait_clip")):SetVisible(false)
    UIComponent(this:Find("unit_frame")):SetVisible(false)
    UIComponent(this:Find("icon_raiding")):SetVisible(true)
    UIComponent(this:Find("building_window")):SetVisible(false)
  end
end
function OnLeftClickUp()
  CampaignUI.SetCameraTarget(m_pos_x, m_pos_y)
end
function OnRightClickUp()
  CampaignUI.SetCameraTarget(m_pos_x, m_pos_y)
end

Quick tests suggest it's working better than decompilers we had before.

I updated README in my repo to say people should generally use that website instead.

How can you re-compile back to luac when you made some changes and such?

EDIT: Neverminded. Forgot to install lue on my hdd.
Other question, every time I try to run a script, I got the UIComponent(Address) issue:

lua: region_details.lua:2: attempt to call global 'UIComponent' (a nil value)
stack traceback:
region_details.lua:2: in main chunk
[C]: ?

Any idea how i can locate the UI adress.

Is it crashing from the game or from somewhere else?

Also, isn't game able to just run `.lua` uncompiled in addition to `.luac`? (or am I really misremembering that)

It does. But I have no clue how to add that. Even adding it in the game as lua (the de-compressed one), the game still use the luac one. I was using the lua 5.1 compiler.

Could you try adding .luac as a 0 byte file in same pack as that generally how patch packs delete files?

It kinda works. Except as the ui file in game looks totally different (with no values nor ui art). I am using a luac file from NTW in S2TW. If I just copy the luac file from NTW to S2TW and it works as in NTW. But when I try to add the same lua file like your suggestion above (without any changes, just de-compressed), all values, art and such are gone. Also if I compile the vanilla lua file to luac (with no any changes, just vanilla) I get the same result. Doesn't make any sense.

Hello, please help decompile this script, when decompiling through the site - it gives an empty result..
