Installation:

1.Mods:

1. Create a new folder in the mods folder in the root directory of the game with a name like luajit_mod.
2. Then copy all the files to that folder.

2.Injector:

Windows

Copy all bin64/windows files to the bin64 folder in the game directory

like: C:\steamapps\Don't Starve Together\bin64\

Launch the game, press ` and type:

print(_Version)

And you can see message started with "LuaJIT".

Linux

I've only tested it on ubuntu, but I can also test it on steamos if someone can help me with the steamos environment, haha!

• Copy all bin64/linux files to the bin64 folder in the game directory
• Rename original game executable dontstarve_steam_x64 to dontstarve_steam_x64_1
• Create new file dontstarve_steam_x64 with the content:

#!/bin/bash
export LD_LIBRARY_PATH=./lib64
export LD_PRELOAD=./lib64/libInjector.so
./dontstarve_steam_x64_1

• Run the shell chmod +x ./dontstarve_steam_x64
• Is't done

macos

• Create a certificate of your own, e.g. with the name Dontstarve

  Official tutorial

• Open the shell

• Switch to your game path

  cd /Users/*/Library/Application Support/Steam/steamapps/common/Don't Starve Together/dontstarve_steam.app

• sudo codesign -fs Dontstarve . /dontstarve_steam.app

• Create a new permissions management file, say called my.xml, with the contents:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "https://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>com.apple.security.cs.allow-dyld-environment-variables</key>
        <true/>
        <key>com.apple.security.cs.disable-library-validation</key>
        <true/>
        <key>com.apple.security.get-task-allow</key>
        <true/>
    </dict>
</plist>

• sudo codesign -d --entitlements ./my.xml ./dontstarve_steam.app
• Copy all bin64/osx files to the MacOS folder in the game directory.
• Rename the original game executable, dontstarve_steam, to dontstarve_steam_1.
• Create a new file with the contents of dontstarve_steam:

#!/bin/bash
export DYLD_INSERT_LIBRARIES=./libInjector.dylib
./dontstarve_steam_1

• Run shell chmod +x . /dontstarve_steam.

3.Enable Mod

In Game，please enable the mod Dontstarveluajit2

If there aren't any other problems, you can now see luajit in the version number in the bottom right corner

How to build

Dept

install CMake, Ninja

• copy lua51.dll to src/x64/release/lua51.dll
• download frida-gum.lib from github/frida, name like frida-gum-devkit-16.2.1-windows-x86_64.exe
• copy frida-gum.lib to src/frida-gum/frida-gum.lib
• in CMakeLists.txt set var GAME_DIR = your game dir
• build by cmake

lua51.dll/so/dylib

windows

Need vs2008 compiler the lua51.dll, also you can use which one in the mod

linux

docker Ubuntu 14.04

macos

macos 10.15

How to debug game:

We need vscode + lua-debug plugin

How to debug game without steam

1. create new file steam_appid.txt at gamedir/bin64
2. the file context is 322330

Pass process args "-enable_lua_debugger"

If you start with stream, please set game config, process start config: "-enable_lua_debugger"

1. find the code

DEBUGGER_ENABLED = TheSim:ShouldInitDebugger() and IsNotConsole() and CONFIGURATION ~= "PRODUCTION" and not TheNet:IsDedicated(
if DEBUGGER_ENABLED then
	Debuggee = require 'debuggee'
end

2. replace the code to

if jit then
	package.preload.debuggee = function()
		local function dofile(filename)
			local load = _VERSION == "Lua 5.1" and loadstring or load
			local f = assert(io.open(filename))
			local str = f:read "*a"
			f:close()
			return assert(load(str, "=(debugger.lua)"))(filename)
		end
		local path = "C:/Users/fesil/.vscode/extensions/actboy168.lua-debug-2.0.4-win32-x64"
		local debugger = dofile(path .. "/script/debugger.lua")
		local Debuggee = {}
		Debuggee.start = function ()
			local port = 12306
			if not TheNet:IsDedicated() then
				port = 12306
			else
				port = 12307
				if TheShard:IsMaster() then
					port = 12307
				elseif TheShard:IsSecondary() then
					port = 12308
				end
			end
			local host = {address = "127.0.0.1:".. port}
			print("debuggee host:", host.address)
			debugger:start(host):event ("autoUpdate", false)
			debugger:setup_patch()
			return "ok", host, debugger
		end
		Debuggee.poll = function ()
			debugger:event "update"
		end
		return Debuggee
	end
end

DEBUGGER_ENABLED = TheSim:ShouldInitDebugger() and IsNotConsole() and not TheNet:IsDedicated()
if DEBUGGER_ENABLED then
	Debuggee = require 'debuggee'
-- if you want debug all scripts, use the code
	local _, _, debugger = Debuggee.start()
-- [[
	if not TheNet:IsDedicated() then
		debugger:event "wait"

	else
		if TheShard:IsMaster() then
			debugger:event "wait"
		elseif TheShard:IsSecondary() then
			debugger:event "wait"
	end
]]
end

3. changed local path = "C:/Users/fesil/.vscode/extensions/actboy168.lua-debug-2.0.4-win32-x64" to your path
4. DEBUGGER_ENABLED = TheSim:ShouldInitDebugger() and IsNotConsole() and CONFIGURATION ~= "PRODUCTION" and not TheNet:IsDedicated() remove CONFIGURATION ~= "PRODUCTION"

force enable the mod

1. add process arg -disable_check_luajit_mod
