## 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.with[0].text;
|
|
var msg = jsonMsg.with[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,
|
|
reducedDebugInfo: false
|
|
});
|
|
client.write('position', {
|
|
x: 0,
|
|
y: 1.62,
|
|
z: 0,
|
|
yaw: 0,
|
|
pitch: 0,
|
|
flags: 0x00
|
|
});
|
|
var msg = {
|
|
translate: 'chat.type.announcement',
|
|
"with": [
|
|
'Server',
|
|
'Hello, world!'
|
|
]
|
|
};
|
|
client.write("chat", { message: JSON.stringify(msg), position: 0 });
|
|
});
|
|
```
|
|
|
|
## 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

## Documentation
|
|
|
|
See [doc](doc/README.md)
|
|
|
|
|
|
## Testing
|
|
|
|
* Ensure your system has the `java` executable in `PATH`.
|
|
* `MC_SERVER_JAR_DIR=some/path/to/store/minecraft/server/ MC_USERNAME=email@example.com MC_PASSWORD=password npm test`
|
|
|
|
## Debugging
|
|
|
|
You can enable some protocol debugging output using `NODE_DEBUG` environment variable:
|
|
|
|
```bash
|
|
NODE_DEBUG="minecraft-protocol" node [...]
|
|
```
