Features

Define packet structures in a single place
Convert between buffer and object representations of packet structures
Designed to be used in any Mu Online server application that runs on node.js

Installation

npm install @mu-online-js/mu-packet-manager

yarn add @mu-online-js/mu-packet-manager

Usage

First, you need to require the library in your code:

const packetManager = require('@mu-online-js/mu-packet-manager');

You can define your packet structure using an object and convert it to a buffer like this:

const messageStruct = {
  header: {
    type: 0xC2,
    size: 'auto',
    headCode: 0xF4,
    subCode: 0x06,
  },
  serverCount: 1,
  serverLoadInfo: [{
    serverId: 0,
    loadPercentage: 20
  }]
}
const message = new packetManager()
  .useStruct(structs.CSServerListResponse)
  .toBuffer(messageStruct);

You can also convert a buffer to an object like this:

const data = Buffer;/* a buffer received from the client/server */
const messageObj = new packetManager()
  .fromBuffer(data)
  .useStruct(structs.CSServerListResponse)
  .toObject();
