Get Steve's position in Minecraft
This is a short flow to demonstrate how to communicate from Node-RED with Minecraft. It uses a TCP request to push "player.getPos()\n" into Steve's world and will receive the coordinate tuple in a node.js buffer format that is converted .toString before printing in the debug panel. Note that you have to run Minecraft and enter a world before triggering this flow.
