* Supports Minecraft version 1.8.1
* Parses all packets and emits events with packet fields as JavaScript
objects.
* Send a packet by supplying fields as a JavaScript object.
* Client
- Authenticating and logging in
- Encryption
- Compression
- Both online and offline mode
- Respond to keep-alive packets.
- Ping a server for status
* Server
- Online/Offline mode
- Encryption
- Compression
- Handshake
- Keep-alive checking
- Ping status
* Robust test coverage. See Test Coverage section below.
* Optimized for rapidly staying up to date with Minecraft protocol updates.
## Projects Using node-minecraft-protocol
* [mineflayer](https://github.com/andrewrk/mineflayer/) - create minecraft
bots with a stable, high level API.
* [mcserve](https://github.com/andrewrk/mcserve) - runs and monitors your
minecraft server, provides real-time web interface, allow your users to
create bots.
* [flying-squid](https://github.com/mhsjlw/flying-squid) create minecraft
servers with a high level API, also a minecraft server by itself.
## Usage
### Echo client example
```js
var mc = require('minecraft-protocol');
var client = mc.createClient({
host: "localhost", // optional
port: 25565, // optional
username: "email@example.com",
password: "12345678",
});
client.on('chat', function(packet) {
// Listen for chat messages and echo them back.
var jsonMsg = JSON.parse(packet.message);
if (jsonMsg.translate == 'chat.type.announcement' || jsonMsg.translate == 'chat.type.text') {
var username = jsonMsg.using[0];
var msg = jsonMsg.using[1];
if (username === client.username) return;
client.write("chat", {
message: msg
});
}
});
```
If the server is in offline mode, you may leave out the `password` option.
### Hello World server example
```js
var mc = require('minecraft-protocol');
var server = mc.createServer({
'online-mode': true, // optional
encryption: true, // optional
host: '0.0.0.0', // optional
port: 25565, // optional
});
server.on('login', function(client) {
client.write('login', {
entityId: client.id,
levelType: 'default',
gameMode: 0,
dimension: 0,
difficulty: 2,
maxPlayers: server.maxPlayers
});
client.write('position', {
x: 0,
y: 1.62,
z: 0,
yaw: 0,
pitch: 0,
onGround: true
});
var msg = { translate: 'chat.type.announcement', using: [
'Server',
'Hello, ' + client.username
]};
client.write("chat", { message: JSON.stringify(msg) });
});
```
## Installation
`npm install minecraft-protocol`
URSA, an optional dependency, should improve login times
for servers. However, it can be somewhat complicated to install.
Follow the instructions from
[Obvious/ursa](https://github.com/Obvious/ursa)
## Documentation
See [doc](doc/README.md)
## Testing
* Ensure your system has the `java` executable in `PATH`.
* Download the appropriate version of `minecraft_server.jar`.
* `MC_SERVER_JAR=path/to/minecraft_server.jar MC_USERNAME=email@example.com MC_PASSWORD=password npm test`
