World of Warcraft in the browser using JavaScript and WebGL.

Background

Wowser is a proof-of-concept of getting a triple-A game to run in a webbrowser, attempting to tackle a wide variety of challenges: data retrieval, socket connections, cryptography, 3d graphics, binary data handling, background workers and audio, to name a few.

Features

Wowser is aiming to be both a low-level API as well as a graphical client, interacting with a World of Warcraft server like an official client would.

Note: Only Wrath of the Lich King (3.3.5a) is currently supported. A copy of the official client is required.

Warning: Do not attempt to use this client on official/retail servers as your account may get banned.

At present, Wowser is capable of:

  • Authenticating by username / password.
  • Listing available realms.
  • Connecting to a realm.
  • Listing characters available on a realm.
  • Joining the game world with a character.
  • Logging game world packets, such as when a creature moves in the vicinity.

In addition, there's good progress on getting terrain and models rendered.

Browser Support

Wowser is presumed to be working on any browser supporting JavaScript's typed arrays and at the very least a binary version of the WebSocket protocol.

Development

Wowser is written in ES2015, developed with webpack and Gulp, compiled by Babel and soon™ to be tested through Mocha.

  1. Clone the repository:

    git clone git://github.com/wowserhq/wowser.git

  2. Download and install Node.js – including npm – for your platform.

  3. Install dependencies:

    npm install

  4. Install StormLib and BLPConverter, which are used to handle Blizzard's game files.

Client

Webpack's development server monitors source files and builds:

npm run web-dev

Wowser will be served on http://localhost:8080.

Pipeline server

To deliver game resources to its client, Wowser ships with a pipeline.

Build the pipeline:

npm run gulp

Keep this process running to monitor source files and automatically rebuild.

After building, serve the pipeline as follows in a separate process:

npm run serve

On first run you will be prompted to specify the following:

  • Path to client data folder (e.g. C:/Program Files (x86)/World of Warcraft/Data)
  • Server port (default is 3000)
  • Number of cluster workers (default depends on amount of CPUs)

Clear these settings by running npm run reset

Disclaimer: Wowser serves up resources to the browser over HTTP. Depending on your network configuration these may be available to others. Respect laws and do not distribute game data you do not own.

Socket proxies

To utilize raw TCP connections a WebSocket proxy is required for JavaScript clients.

Websockify can - among other things - act as a proxy for raw TCP sockets.

For now, you will want to proxy both port 3724 (auth) and 8129 (world). Use a different set of ports if the game server is on the same machine as your client.

npm run proxy 3724 host:3724
npm run proxy 8129 host:8129
