NodeJS Online Game Template

Barebone NodeJS project for any multiplayer games.

UPDATE: I developed a lightweight alternative for Socket.IO, based on Engine.IO, the engine behind Socket.IO as well. It focus on transmiting binary data instead of string-based as in Socket.IO, so the target is to improve the networking performance. Unfortunatelly, I didn't have time for testing/integrating it yet. It would be nice if somebody can help me integrate it with this repo? Feel free to contact me for further discussion. Thank you so much!

Requirements

NodeJS / NPM
Socket.IO
ExpressJS

Getting started

Clone the source code from Github
Run npm install to install needed packages
Writing your code in server/server.js and client/js/game.js
Run your game server with npm start command

Server side

You can write all the server side code in server/server.js

io.on('connection', function (socket) {
  console.log("Somebody connected!");
  // Write your code here
});

Client side

For writing client side code, find client/js/game.js

There are 3 method to process your client logic: handleNetwork, handleLogic and handleGraphics

handleNetwork is where you receive and process all messages sent from Server:

Game.prototype.handleNetwork = function(socket) {
  console.log('Game connection process here');
  console.log(socket);
  // This is where you receive all socket messages
}

The socket is the connection object of your game client, use this to communicate with the server.

handleLogic is where you update your game logic (handling input, update game information,...)

Game.prototype.handleLogic = function() {
  console.log('Game is running');
  // This is where you update your game logic
}

handleGraphics is where you draw your game:

Game.prototype.handleGraphics = function(gfx) {
  // This is where you draw everything
}
