MCPI-Scratch

A ScratchX extension application for the Minecraft Pi Protocol

Introduction

MCPI-Scratch lets you write Scratch scripts to manipulate Minecraft.

More specifically, its an extension application for the ScratchX editor that allows you to use blocks that represent the Minecraft Pi Protocol API. It actually uses a slightly cut-down version of the API specified by the RaspberryJuice mod which allows it to connect to both:

• Minecraft Pi Edition
• CraftBukkit server with the RaspberryJuice mod
