Minecraft plugin for demos

Requirements

• IntelliJ IDEA (tested with 2019.2.3 version).
• Spigot v1.3.1.
• Minecraft client (v1.3.1).
• Web server accepting PUT requests at http://raspberrypi:1880/bulb/color.
• (optional) MQTT server running at tcp://raspberrypi:1883

Building

• Open project in IntelliJ IDEA.
• In the "Maven" panel on the top right choose "package"

Running

Behaviours

HTTP

• On right-clicking block of wool, will send RGB color of the wool by PUT to http://raspberrypi:1880/bulb/color with body of {"rgb_color": [10, 200, 50]} kind.
• On pulling any lever up, will PUT to http://raspberrypi:1880/bulb/color with body {"rgb_color": [255, 0, 0]}.
• On pulling any lever down, will PUT to http://raspberrypi:1880/bulb/color with body {"rgb_color": [0, 255, 0]}.
• On POST to localhost:4567/command with body {"command": "<some minecraft command>"} will execute it. Can be used to e.g. place and remove blocks (e.g. {"command": "setblock 39 16 204 minecraft:redstone_torch"} and
  {"command": "setblock 39 16 204 air"}.

MQTT

Following will work only MQTT server is present.

• On right-clicking block of wool, will publish RGB color of the wool to minecraft/bulb/color in JSON format. E.g. {"rgb_color": [10, 200, 50]}.
• On pulling any lever up, will publish to minecraft/bulb/color message {"rgb_color": [255, 0, 0]}.
• On pulling any lever down, will publish to minecraft/bulb/color message {"rgb_color": [0, 255, 0]}.
• Will listen to minecraft/command. If message containing JSON with command field is published, will execute that command (e.g. publishing {"command":"stop"} will stop server).
