Sonic Pi now supports a simple API for interacting with Minecraft Pi - the special edition of Minecraft which is installed by default on the Raspberry Pi’s Raspbian Linux-based operating system.
The Minecraft Pi integration has been designed to be insanely easy to use. All you need to do is to launch Minecraft Pi and create a world. You’re then free to use the mc_* fns just like you might use play and synth. There’s no need to import anything or install any libraries - it’s all ready to go and works out of the box.
The Minecraft Pi API takes care of managing your connection to the Minecraft Pi application. This means you don’t need to worry about a thing. If you try and use the Minecraft Pi API when Minecraft Pi isn’t open, Sonic Pi will politely tell you. Similarly, if you close Minecraft Pi whilst you’re still running a live_loop that uses the API, the live loop will stop and politely tell you that it can’t connect. To reconnect, just launch Minecraft Pi again and Sonic Pi will automatically detect and re-create the connection for you.
The Minecraft Pi API has been designed to work seamlessly within live_loops. This means it’s possible to synchronise modifications in your Minecraft Pi worlds with modifications in your Sonic Pi sounds. Instant Minecraft-based music videos! Note however that Minecraft Pi is alpha software and is known to be slightly buggy. If you encounter any problems simply restart Minecraft Pi and carry on as before. Sonic Pi’s automatic connection functionality will take care of things for you.
It is highly recommended that you use a Raspberry Pi 2 if you wish to run both Sonic Pi and Minecraft at the same time - especially if you want to use Sonic Pi’s sound capabilities.
At this stage, Sonic Pi supports basic block and player manipulations which are detailed in Section C.1. Support for event callbacks triggered by player interactions in the world is planned for a future release.
