Set up a modern project and start building JavaScript HTML5 games with Phaser 3
In this tutorial, I want to detail an optimal setting to start using the production gamePhase shifter 3.
Let's installphaserUse in foldernpm:
npm init -y
npm install phaserSet up nowpackageBundle our game:
npm install -g parcel-bundlerNow create a game.js file with this content:
import Phaser from 'phaser'
new Phaser.Game()
Now run
parcel watch game.jsand Parcel will build our JavaScript in the dist/game.js file.
Now create an index.html file with this content:
<!DOCTYPE html>
<html>
<head>
<script src="./dist/game.js"></script>
</head>
</html>
Install browser-sync to run an HTTP server with the content of this folder:
npm install -g browser-sync
then run
browser-sync start --server --files "."
The above command watches all files in the current folder (and all subfolders) for changes, and launches a web server on port 3000, automatically opening a browser window to connect to the server.
Any time you change a file, the browser will refresh.
This will be very useful while we prototype our games.
You should now see a blank screen in your browser, because we initialize Phaser:
import Phaser from 'phaser'
new Phaser.Game()
but nothing else happens.
Copy this code in game.js:
import Phaser from 'phaser'
function preload() {
this.load.setBaseURL(‘http://labs.phaser.io’)
this.load.image(‘sky’, ‘assets/skies/space3.png’)
this.load.image(‘logo’, ‘assets/sprites/phaser3-logo.png’)
this.load.image(‘red’, ‘assets/particles/red.png’)
}
function create() {
this.add.image(400, 300, ‘sky’)
const particles = this.add.particles(‘red’)
const emitter = particles.createEmitter({
speed: 100,
scale: { start: 1, end: 0 },
blendMode: ‘ADD’,
})
const logo = this.physics.add.image(400, 100, ‘logo’)
logo.setVelocity(100, 200)
logo.setBounce(1, 1)
logo.setCollideWorldBounds(true)
emitter.startFollow(logo)
}
const config = {
type: Phaser.AUTO,
width: 800,
height: 600,
physics: {
default: ‘arcade’,
arcade: {
gravity: { y: 200 },
},
},
scene: {
preload: preload,
create: create,
},
}
const game = new Phaser.Game(config)
and you should quickly see the Phaser demo app running in your browser:
