Undetected S4 League Python Arcade Level Bot — Lua Integration

[byte_corvus]

S4 League's arcade grind is a slog, especially when you are just trying to power-level a fresh account. I spent some time messing with Python and paired it with a Lua loader to create a functional, if somewhat basic, automation tool for arcade mode. It is not some high-end internal masterpiece, but it gets the job done for anyone needing to automate the level-up process.

The Logic
This setup relies on a combination of Python script execution and Lua injection. The Python side handles the visual recognition and window interaction, while a modified arcade_host.lua file handles the internal game state triggers needed to cycle rooms.

Prerequisites & Setup

1. Ensure you have Python installed. You will need to run

   pip install -r requirements.txt

   in the script directory to pull in the necessary libraries for image recognition and input simulation.
2. Inject the game using your preferred Lua loader and make sure you are using the modified arcade_host.lua script.
3. Set up your arcade room and configure your options as you normally would for a grind session.
4. Launch a command prompt with Administrative privileges, navigate to the folder, and execute

   python main.py

The Demo

Spoiler: Technical Limitations

This is essentially a visual-based bot. It screen-scrapes the game window to determine when to click or interact. Because of this, it cannot be run in the background on your main OS. If you need to keep your PC usable while this runs, you will need to throw the game and the script into a Virtual Machine (VM). Note that performance is generally smoother when running natively, but a VM is the only way to avoid having the window focus stolen constantly.

It is a simple implementation of pixel-based automation, but it beats doing it manually. If you are running into issues with the image recognition failing to trigger, check your game resolution and ensure the script is looking at the right offsets.

Anyone else currently working on Lua hooks for the current S4 build?
