ScriptOne - Lua scripting framework for Unity games

ScriptOne

A Lua framework for Unity games - alongside MelonLoader and BepInEx

Write one small text file, and the game does something new.

No C#, no compiler, no build setup - and nothing to learn beyond Lua.

ScriptOne looks inside the game you own and shows you what you can change.

What it is

ScriptOne is a framework, the same kind of thing MelonLoader and BepInEx are - it just covers a different area: Lua. Those two load compiled mods; ScriptOne lets a plain text file be the mod.

It works on both Unity flavours, Mono and Il2Cpp, and it does not compete with either loader: it runs under MelonLoader, alongside BepInEx, or on its own when neither is installed.

Why you might want it

• []You can mod without being a programmer. No Visual Studio, no compiler, no project. A text editor is enough.[/]

  []It works in games nobody made a modding API for. ScriptOne reads the game you actually have and writes down what can be called - that list is different in every game, and it does not need anyone to prepare it first.[/]

  []Your mod is one file. Easy to change, easy to send to a friend, easy to throw away.[/]

  []It keeps working when things move. New game version, or you removed your mod loader - ScriptOne looks again and carries on.[/]

  Features

  • []One file is the whole mod. A .lua file in LuaScripts\, and that is it.[/]

    []Both Unity backends - Il2Cpp and Mono. The installer reads which one your game is and installs the matching build; there is nothing for you to pick.[/]

    []Three ways to run, decided for you - MelonLoader plugin, alongside BepInEx, or standalone with its own loader.[/]

    []It survives losing the loader. Delete MelonLoader or BepInEx later and your scripts keep running - no second install, nothing to click.[/]

    []An API reference written for your installation, into ScriptOne\documentation\ - what this game offers, not what some other build did.[/]

    []Events, timers and per-script memory that survives a restart.[/]

    []It tells you when the frame tick is dead. A host can start perfectly and still never see a frame; then timers and events are silently dead while the log looks flawless. ScriptOne says so instead of looking healthy.[/]

    []Sandboxed by default - no io, no os, no require, and a step budget that stops an endless loop instead of freezing your game.[/]

    Installation

    One file: ScriptOne-Installer.exe. Double-click it, check the folder it found, press the button.

    There is nothing to unpack and no build to choose - it reads the Unity backend and the bit width out of the game's own binaries and installs the one that fits.

    What it does depends on what is already in the game folder:

    • []No mod loader - ScriptOne installs its own loader plus the host and runs on its own.[/]

      []MelonLoader active - installs as a MelonLoader plugin, so your other mods keep working. It also leaves a disarmed loader of its own behind, which stays silent and takes over by itself if you ever remove MelonLoader.[/]

      []BepInEx active - ScriptOne takes the entry point and starts BepInEx itself afterwards. Your plugins load exactly as before, and ScriptOne survives you removing BepInEx later. The loader's original doorstop_config.ini is saved first, and Remove puts it back byte for byte.[/]

      Running it again updates in place. The button says Update when it does.
