# Heaps.io
Compile Heaps.io games to JavaScript and ship them to Wavedash as a static folder.
Source: https://docs.wavedash.com/engines/heaps
[Heaps.io](https://heaps.io/) is a 2D/3D game engine written in Haxe (used by Dead Cells and Northgard). The Haxe compiler targets JavaScript, producing a single `.js` bundle you can serve as static files alongside a tiny HTML shell.
## Setup
Install Haxe and the `heaps` library once:
```bash
# brew install haxe / apt install haxe / etc.
haxelib install heaps
```
Minimal project layout:
```
my-game/
├── build.hxml
├── src/
│ └── Main.hx
├── bin/
│ └── index.html
└── wavedash.toml
```
`src/Main.hx`:
```haxe
class Main extends hxd.App {
override function init() {
var box = new h2d.Graphics(s2d);
box.beginFill(0xFFFFFF);
box.drawRect(0, 0, 40, 40);
box.endFill();
}
override function update(dt:Float) {
// per-frame logic
}
static function main() { new Main(); }
}
```
`build.hxml`:
```
-cp src
-main Main
-lib heaps
-js bin/main.js
-D js-es6
```
`bin/index.html`:
```html
```
Heaps auto-attaches to `
