Getting Started with Phaser.js
Starting with Phaser.js is simple, as the framework is lightweight and heavily documented. Here’s a step-by-step guide to get you up and running:
Installation
1. Use a CDN
The quickest way to include Phaser in your project is to add it via a Content Delivery Network (CDN) using this script in your HTML:
html
<script src="https://cdn.jsdelivr.net/npm/phaser@3/dist/phaser.js"></script>
2. Download Locally
You can also download the library directly from Phaser’s official GitHub page and include it:
html
<script src="path-to-local-directory/phaser.js"></script>
3. Using npm
For projects with build pipelines, use npm to install Phaser:
bash
npm install phaser
A Simple Example
Here’s a basic example of a Phaser game to give you a taste of what you can create.
HTML Setup
Start by setting up your HTML file:
html
<!DOCTYPE html>
<html>
<head>
<title>Phaser Game</title>
<script src="https://cdn.jsdelivr.net/npm/phaser@3/dist/phaser.js"></script>
</head>
<body>
<script src="game.js"></script>
</body>
</html>
Basic Game Code
Create a `game.js` file and add this simple Phaser game setup:
javascript
const config = {
type: Phaser.AUTO,
width: 800,
height: 600,
scene: {
preload: preload,
create: create,
update: update
}
};
const game = new Phaser.Game(config);
function preload() {
this.load.image('sky', 'assets/sky.png');
}
function create() {
this.add.image(400, 300, 'sky');
}
function update() {
// Game logic goes here
}This simple game displays an image as the game background, which you can build upon with additional elements and interactivity.
