A fresh, _modern_ & lightweight HTML5 game engine
-------------------------------------------------------------------------------
melonJS 2 is a modern version of the melonJS game engine that was first released in 2011. It has been rebuilt entirely using ES6 class, inheritance and semantic, and bundled using [esbuild](https://esbuild.github.io) for blazing fast build performance and provide modern features such as tree-shaking.
>Note: migrating an existing project to melonJS 2 (version 10.0 and higher) will definitely break your game (ES6 semantic and 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](https://github.com/melonjs/melonJS/wiki/Upgrading-to-melonJS-2). If you are looking at the legacy version (9.x and lower) of melonJS, you can find it [here](https://github.com/melonjs/melonJS/tree/legacy) under the _legacy_ branch.
[melonJS](https://melonjs.org/) is open-source, licensed under the [MIT License](LICENSE.md), and actively developed and maintained with the help of a small team of enthusiasts at AltByte in Singapore.

# Using melonJS
### For your first time using melonJS, this is where you start
- [melonJS: Hacking a Platformer Game](https://melonjs.org/tutorial/)
You may find it useful to skim the overview found at the wiki [Details & Usage](https://github.com/melonjs/melonJS/wiki#details--usage)
When starting your own projects, checkout our [ES6 x Vite boilerplate](https://github.com/melonjs/es6-boilerplate) or the [TypeScript x Vite boilerplate](https://github.com/melonjs/typescript-boilerplate)

### Basic [Hello World](https://jsfiddle.net/obiot/4o9f02tc/) Example
```JavaScript
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;
}
// set a gray background color
me.game.world.backgroundColor.parseCSS("#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 !"
}));
});
```
> Simple hello world using melonJS 2 (version 10.x or higher)

Plugins
-------------------------------------------------------------------------------
melonJS provide a plugin system allowing to extend the engine capabilities.
Here is the list of official plugins maintained by the melonJS team:
- [debug-plugin](https://github.com/melonjs/debug-plugin) - a debug panel for inspecting game objects
- [tiled-inflate-plugin](https://github.com/melonjs/tiled-inflate-plugin) - enable loading and parsing of zlib and gzip compressed [Tiled](https://www.mapeditor.org/) maps
- [spine-plugin](https://github.com/melonjs/spine-plugin) - [Spine](http://esotericsoftware.com) runtime integration to render Spine skeletal animations
If you wish to develop your own plugin, we also provide a [plugin template](https://github.com/melonjs/plugin-template) to help you get started.
Download melonJS
-------------------------------------------------------------------------------
The latest builds with corresponding release note are available for direct download [here](https://github.com/melonjs/melonJS/releases).
melonJS 2 now only provides an ES6 Bundle :
| build | description |
| ------------------- | ----------- |
| `index.js` | a tree-shakeable ES6 Module Directory |
| `index.d.ts` | typescript declaration files |
>Note: if you need your application to be compatible with ES5, refer to our [boilerplate](#using-melonjs) that provides automatic transpiling to ES5.
The latest version of melonJS can be installed through [NPM](https://www.npmjs.com/package/melonjs) :
$ npm install melonjs
And then import melonjs in your project using :
$ import * as me from 'melonjs';
Or it can simply be added to your html, using [jsDeliver](https://www.jsdelivr.com/package/npm/melonjs) content delivery network (CDN) :
```html
```
> 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](https://github.com/melonjs/es6-boilerplate)
