Redbyte
by Stonygeist
Redbyte lets players program robots in-game with a simple custom language, giving each robotic entity its own scripted behavior.
What it does
Robots in Redbyte are programmable entities that players control with scripts written in a simple custom language. Instead of relying on predefined automation, a player writes the logic that a robot follows, and the robot can interact with the world around it. The mod is aimed at building programmable systems in place of static machines, and it suits players who like designing their own automation to solve problems.
Redbyte is a Forge mod that runs on client and server, so both the server and every player need it. Its published builds cover 1.21.1 – 1.21.11, with 0.6.6 for 1.21.11 as the latest file, and it is released under the MIT License as open source. The author describes the project as still in an early phase, with documentation for scripts planned for a later release and an expandable tech ecosystem planned for future versions.
Key features
Programmable robots
Robotic entities are placed in the world and controlled through scripts that define their behavior.
Custom simple language
Robot behavior is written in a small language built for the mod, so no outside programming setup is needed.
World interaction
Robots carry out utility tasks that involve the blocks and space around them.
Player-driven logic
Automation is built by the player from scratch rather than chosen from fixed machine recipes.
Compatibility
Latest build for each game version and loader.
1.21.x11 of 11 versions with builds

Use cases
Prototyping automation
Players can test automation ideas by writing a robot script and watching how it acts in the world.
Creative problem solving
The mod suits experimentation, where a player designs a helper for a task and adjusts the script until it works.
Who it’s for: Redbyte suits players who enjoy scripting and designing their own systems, and tech players looking for programmable automation rather than fixed machines. Because the mod is in an early phase, it fits players who accept that features are still changing.
