A CoffeScript, HTML5, Canvas, Web Sockets, Node.js multiplayer puzzle platformer experiment. I am busy porting a puzzle platformer of mine to HTML5 and thought hey why not use CoffeeScript and then I thought why not using Web Sockets and make it multiplayer. As the game stands multiple players can join a server and see the other players moving around a 2D map with tile collision detection. The code has been converted to CoffeeScript using js2coffee and still needs a lot of porting to proper CoffeeScript classes. See the todo section below for things that need to be done.
- Works best in latest Chrome, some versions of Firefox don't update at 60fps
- Requires node, express, socket.io, coffee-script (install via npm)
- Install dependencies with: npm install
- On the server run: node web.js to start the server
- Then open up http://localhost:3000/index.html in Chrome
- To compile the client code run: coffee -w -c ./ public/ game/ This will watch the file for any updates and automatically compile to JavaScript
- Keys: (left), (right) and (A) to jump. Hold down (A) to jump higher.
- Use Jade templates for client
- Convert client code to use CoffeeScript classes
- Provide way for client to specify which server to connect too
- Send player input versus positions
- Provide way to set player input update rate
- Do all game logic on server
- Latency compensation and interpolation
Use package files to list dependenciesHost game static files using Node and Express (at the moment no web server)Convert server code to CoffeeScript- so so much more
