GoBlocks

Players place blocks that represent code, and the programs they build run in the world, so the creations they make can react to play. The system is modeled on Scratch and is described as the first block-based programming language for Minecraft in the MCDiamondFire style. Players do not need previous coding knowledge, and the datapack includes tutorials and an interface meant for learning from the first session.

The datapack suits schools, coding clubs and teachers who want to show people how code works through a game. It is also used on multiplayer servers that host events and challenges. Running the function gb:give-all hands out the starter items. The author marks the project as early beta with known bugs, and the datapack is updated regularly, with update logs released only for major updates. It is incompatible with Bukkit, Spigot and Paper.

Installation is a datapack on Fabric, Forge or Quilt, for game versions 1.17 – 1.19.3. The latest file for each loader is 1.2m for 1.19.3, published 2022-12-29. Server owners install it, and players can join with or without it.
