UniTAS

A tool that lets you TAS unity games

• The tool doesn't bypass anti cheat or anything, USE AT YOUR OWN RISK!
• The tool is early in development, TASes made in earlier versions may not work in later versions
• This is a BepInEx 5 mod

TASing in UniTAS

Currently, you write a script in lua to control the game rather than recording inputs in game

This is planned to change to a more traditional emulator-like workflow, with frame advancing support later on

To get the hang of it, check the tutorial here and if stuck on anything, the wiki should help you out, otherwise you can ask on discord or GitHub discussions

What games work

• Currently, anything that BepInEx 5 supports, ranging from unity 3 to latest, and games that use Mono and not IL2CPP
• Check compatibility-list for tested games
• Any games using rewired input system has limited support as of now, games using this may not work correctly
