MelonJS: a Fresh & Lightweight JavaScript/HTML5 Game Engine

melonJS 2

A fresh, modern & lightweight HTML5 game engine

melonJS 2 is a modern version of the melonJS game engine. It has been rebuilt almost entirely using ES6 class, inheritance and semantic, and is bundled using Rollup to provide modern features such as transpiling and tree-shaking.

Note: migrating an existing project to melonJS 2 (version 10.0 and higher) will definitely break your game (ES6 semantic, no more Jay inheritance, nodeJS event emitter, and no backward compatibility with deprecated legacy APIs), and you might want to read first this small step by step guide on upgrading to melonJS 2. If you are looking at the legacy version (9.x and lower) of melonJS, you can find it here under the legacy branch.

melonJS is open-source, licensed under the MIT License, and actively developed and maintained with the help of a small team of enthusiasts at AltByte in Singapore.

Using melonJS

Basic Hello World Example

import * as me from "https://esm.run/melonjs";

me.device.onReady(function () {
    // initialize the display canvas once the device/browser is ready
    if (!me.video.init(1218, 562, {parent : "screen", scale : "auto"})) {
        alert("Your browser does not support HTML5 canvas.");
        return;
    }

    // add a gray background to the default Stage
    me.game.world.addChild(new me.ColorLayer("background", "#202020"));

    // add a font text display object
    me.game.world.addChild(new me.Text(609, 281, {
        font: "Arial",
        size: 160,
        fillStyle: "#FFFFFF",
        textBaseline : "middle",
        textAlign : "center",
        text : "Hello World !"
    }));
});

Download melonJS

The latest builds with corresponding release note are available for direct download here.

Since version 10.0.0 melonJS provides different build options :

build	description
`melonjs.module.js`	the ES6 Module (ESM) Bundle
`melonjs.module.d.ts`	typescript declaration file for the ES6 Module (ESM) Bundle
`melonjs.js`	a ES5 UMD Bundle (directly transpiled from the ES6 version)
`melonjs.min.js`	a minified version of the ES5 UMD bundle

Alternatively, the latest version of melonJS can be installed through NPM :

$ npm install melonjs

If you need to import the ES6 module of melonjs (e.g. for Webpack):

$ import * as me from 'melonjs/dist/melonjs.module.js';

Or can simply be added to your html, using jsDeliver content delivery network (CDN) :

<!-- load the ES6 module bundle of melonJS v10.0 -->
<script src="https://esm.run/melonjs@10.0"></script>
<!-- omit the version completely to get the latest one -->
<!-- you should NOT use this in production -->
<script src="https://esm.run/melonjs"></script>

Note: starting from the 10.0.0 version, the debug plugin is no longer provided as part of the melonJS library release, and has been moved to the official boilerplate

Building melonJS

For most users, all you probably want is to use melonJS, and all you need then is just to download the latest built release to get started. The only time you should need to build melonJS is if you want to contribute to the project and start developing on it.

To build your own version of melonJS you will need to install :

The Node.js JavaScript runtime and the NPM package manager

Once Node.js and NPM have been installed, you need to install build dependencies, by executing the following in the folder where you cloned the repository :

$ [sudo] npm install

Then build the melonJS source by running:

$ npm run build

The generated library will be available under the build directory :

melonjs.js : plain ES5 UMD bundle
melonjs.min.js : minified ES5 UMD bundle
melonjs.module.js : plain ES6 module

To run the melonJS test suite simply use the following:

$ npm run test

This will run the jasmine spec tests with the output displayed on the shell. Do note that the latest Chrome version is required, as the test unit will run the Browser in a headless mode (in case of failed tests, upgrade your browser).

Building the documentation

Similarly, you can build your own copy of the docs locally by running :

$ npm run doc

The generated documentation will be available in the docs directory

WIP Builds

melonJS uses Travis-CI for automated testing and build uploads. The latest build artifacts can be downloaded from the melonjs-builds bucket.

Questions, need help ?

Top Javascript Game Engines and Libraries

Gaming is something everyone enjoys, be it a 10-year-old kid or an employed person. There’s no better recreation at home than to plug in your headphones or speakers and get lost in the world of video games. After all, what’s better than fighting criminals or driving supercars at very high speed, or play a sport you are bad at?

For Developing the game you adore so dearly, there has to be a lot of work that goes on for months, comprising of a huge team of developers, designers, and whatnot. What might seem like a small game has a lot of work and sweat put into it, mostly.

Game development these days is mostly done using Game Engines, simple software that allows you to create the graphics, sound, animations, physics, and dynamics of the game.

So in this article, we are going to talk about Game Engines and what is the best possible option right now. But before going into detail, let us talk about the basics.

JavaScript Snake Game Tutorial - Develop a Simple Snake Game

Work on real-time JavaScript Snake game project and become a pro

Snake game is an interesting JavaScript project for beginners. Snake game is a single-player game, which we’ve been playing for a very long time. The game mainly consists of two components – snake and fruit. And we just need to take our snake to the food so that it can eat and grow faster and as the number of fruits eaten increases, the length of snake increases which makes the game more interesting. While moving if the snake eats its own body, then the snake dies and the game ends. Now let’s see how we can create this.

JavaScript Project Prerequisites

To implement the snake game in JavaScript you should have basic knowledge of:

1. Basic concepts of JavaScript

2. HTML

3. CSS

Download Project Code

Before proceeding ahead please download source code of Snake Game: Snake Game in JavaScript

Steps to Build the Project – JavaScript Snake game

1. Create Html file

HTML builds the basic structure. This file contains some basic HTML tags like div, h1, title, etc. also we’ve used bootstrap (CDN is already included).

index.html:

Code:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>DataFlair Snake game</title>
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous">
    <link rel="stylesheet" href="static/style.css">
</head>
<body>
    <div class="container">
        <div class ="Jumbotron">
        <h1>DataFlair Snake game using vanilla JavaScript</h1>

            <h2 class="btn btn-info"> 
                Score:   0 
            </h2>

            <div class="containerCanvas">
                <canvas id="canvas" width="500" height="500" class="canvasmain"> </canvas>
            </div>
        </div>
    </div>
    <script src="static/fruit.js"></script>
    <script src="static/snake.js"></script>
    <script src="static/draw.js"></script>
</body>
</html>

We have used simple HTML tags except

Game Development with .NET

We’ve launched a new Game Development with .NET section on our site. It’s designed for current .NET developers to explore all the choices available to them when developing games. It’s also designed for new developers trying to learn how to use .NET by making games. We’ve also launched a new game development Learn portal for .NET filled with tutorials, videos, and documentation provided by Microsoft and others in the .NET game development community. Finally, we launched a step-by-step Unity get-started tutorial that will get you started with Unity and writing C## scripts for it in no time. We are excited to show you what .NET has to offer to you when making games. .NET is also part of Microsoft Game Stack, a comprehensive suite of tools and services just for game development.

.NET for game developers

.NET is cross-platform. With .NET you can target over 25+ different platforms with a single code base. You can make games for, but not limited to, Windows, macOS, Linux, Android, iOS, Xbox, PlayStation, Nintendo, and mixed reality devices.

C## is the most popular programming language in game development. The wider .NET community is also big. There is no lack of expertise and support you can find from individuals and user groups, locally or online.

.NET does not just cover building your game. You can also use it to build your game’s website with ASP.NET, your mobile app using Xamarin, and even do remote rendering with Microsoft Azure. Your skills will transfer across the entire game development pipeline.

Available game engines

The first step to developing games in .NET is to choose a game engine. You can think of engines as the frameworks and tools you use for developing your game. There are many game engines that use .NET and they differ widely. Some of the engines are commercial and some are completely royalty free and open source. I am excited to see some of them planning to adopt .NET 5 soon. Just choose the engine that better works for you and your game. Would you like to read a blog post to help you learn about .NET game engines, and which one would be best for you?
