If you have another computer that can run Scratch 1.4 that is networked with a Raspberry Pi , then you can use it to interact with the Minecraft world on the Pi.
You’l need to find out the IP address of your other computer – for this exercise I’ll assume its 10.11.12.13 so you’ll need to substitute your real address
To do this, run ScratchGPIO on your Pi and add On Green Flag – broadcast Connect10.11.12.13
This hands over ScratchGPIO control to your main computer
So run up Scratch 1.4 on your main computer and enable Remote Sensor Connections (RSC) by right-clicking on the last Sensor block and enabling it.
Go back onto your Pi, and launch Minecraft and create a new world.
To connect to this world from Scratch on your other computer, add On Green Flag – broadcast MinecraftStart
You should see a message come up to say ScratchGPIO is connected.
You should create 3 variables – MineX MineY and MineZ .
You can then set these variables to different values and do a Broadcast MinecraftMove to update player position
Or the same variables can be used to set a block position and set it or clear it or get the value of the block
