MCreator Link: Getting started with Raspberry Pi

Section

This tutorial assumes you have already installed MCreator Link in your Minecraft Client. If this is not the case, please first read the installation tutorial for the MCreator Link for Minecraft.

Installation of MCreator Link on Raspberry Pi

MCreator Link for Raspberry Pi supports all Raspberry Pi boards, BananaPi, and BananaPro boards and Odroid boards. MCreator Link needs Raspbian OS to be installed on your Pi in order to properly work.

Install the latest version of the Raspbian on your Raspberry Pi
Run the following command in the terminal on your Raspberry Pi connected to the internet:
```
curl -sL https://mcreator.net/linkpi | sudo bash
```
After the setup is complete, the service called minecraftlink will be automatically started
You can verify if the service is running properly by entering the following command
```
sudo service minecraftlink status
```
You can connect to your Raspberry Pi via MCreator Link Minecraft interface if the computer and the Raspberry Pi are on the same network

Connecting to Raspberry Pi from MCreator Link

Once the MCreator Link service is installed on the Raspberry Pi, we can connect to it from Minecraft.

Launch the Minecraft with Minecraft Forge and MCreator Link installed
On the home screen, press L to open MCreator Link window
Make sure that your Raspberry Pi is on the same network as the Minecraft you are using to connect to Pi from
Wait a few moments on the MCreator Link screen so the Raspberry Pi gets recognized. If it does not appear on the screen, click on the IP connect button and enter the IP of your Raspberry Pi (Raspberry Pi IP address) and click Connect to manually connect to your Raspberry Pi
If the connection is successful, the green CONNECTED text will be shown next to the selected device

Verifying the connection

We can verify the connection by opening one of the Minecraft Worlds with cheats enabled. Once you are in the world, enter the following command in the chat:

/link device

When you execute this command, the name of the connected device should be shown. The number of digital and analog pins should be shown too.

Basic pin control test

To do a basic test, connect LED to the GPIO as shown on this website.

We can use this LED to test if the connection to the MCreator Link is working. First, we need to set the pin 1 to the output mode, so it can control the LED power state. Enter the following command in the Minecraft Chat:

/link pinmode 1 out

Next, we turn the LED on:

/link digitalwrite 1 1

We set the pin 1 to the high state (1). The onboard LED should turn on. We can now turn it back off by entering the following command:

/link digitalwrite 1 0

Pin/port numbers

MCreator Link for Raspberry Pi uses pi4j Java mapping of wiringPi software. Pin mappings for your device can be found on the following links:
