# Minecraft Binding

This binding integrates Minecraft with openHAB through the [spigot plugin](https://github.com/ibaton/bukkit-openhab-plugin/releases/download/1.5/OHMinecraft.jar) ([sources](https://github.com/ibaton/bukkit-openhab-plugin/tree/master)).

The binding allows reading of server and player data.
It furthermore keeps track of redstone power going below signs and links them to Switch items.

## Discovery

The Minecraft binding automatically finds all Minecraft servers running [this plugin](https://github.com/ibaton/bukkit-openhab-plugin/releases/download/1.9/OHMinecraft.jar) on the local network.
Servers can be added manually if they are not found automatically.

::: tip Note
Discovery uses zeroconf, which may not work if you host a Minecraft server in a virtual machine or container.

### Example Thing Definition

The easiest method to add Minecraft servers, players, and signs is use the automatic discovery through Paper UI. However, you can manualy define the objects using thing configuration files. Players and signs are connected through Minecraft server [bridges](https://www.openhab.org/docs/configuration/things.html#defining-bridges-using-files).

```xtend
Bridge minecraft:server:myminecraftserver "Minecraft server for Friends" @ "Minecraft" [ hostname="192.168.1.100", port=10692 ] {
  Thing player my_name "My Minecraft User" @ "Minecraft" [ playerName="minecraft_username" ]
  Thing player friends_name "My Friend's Minecraft User" @ "Minecraft" [ playerName="friends_username" ]
  Thing sign sign_name "Example Sign" @ "Minecraft" [ signName="sensor" ]
}
```
