Phaser 3 - Game configuration

Phaser 3 - Game configuration

Phaser is one of the most powerful 2D engines written in JavaScript. Now with Phaser3 it is even more powerful, but some things have changed. Let’s explore the initialization of a Phaser3 canvas which is very similar to the previous version, but requires now a configuration object.

To initialize the canvas of the game you need to create a new instance of Phaser and pass the desired configuration in one configuration object. If the config object does not contain an expected key, Phaser will apply the default values as shown in the table below.

include 'phaser'
var config = {}; 
var game = new Phaser.Game(config); 

Next, we need to fill in some options. All options and their default values can be found at the config parser here. But the most time you won’t need all of them. The following example shows the most commonly used ones.

var config = {
   height: 600,
   parent: 'idofcontainer',
   title: "Mygame",
   url: "",
   version: "0.0.1",
   scene: {preload: preload, creat: create, update : update},
   fps: 30

#Load the reources
function preload() {...}

#Create the game objects
function create(){...}

#Update the game objects
function update(){...}

Note: You can use the function structure above for small projects, but for complex projects, it is recommended, to split the game into multiple files, especially for with multiple scenes. Therefore, you should take a look at a loader such as Webpack.
