Features added/changed from original PlayCanvas:

'physics' component used instead of 'rigidbody' component.
'multibody' component added to allow multibody articulations for much greater stability of many-jointed bodies.
'joint' component changed significantly from official playcanvas joint component
EventHandler can use any key for events, not only strings; also symbols and numbers.
Quat.distance() measures rotational distance between two quaternions.

Usage

Here's a super-simple Hello World example - a spinning cube!

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>PlayCanvas Hello Cube</title>
    <meta name='viewport' content='width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no' />
    <style>
        body {
            margin: 0;
            overflow: hidden;
        }
    </style>
    <script src='https://code.playcanvas.com/playcanvas-stable.min.js'></script>
</head>
<body>
    <canvas id='application'></canvas>
    <script>
        // create a PlayCanvas application
        const canvas = document.getElementById('application');
        const app = new pc.Application(canvas);

        // fill the available space at full resolution
        app.setCanvasFillMode(pc.FILLMODE_FILL_WINDOW);
        app.setCanvasResolution(pc.RESOLUTION_AUTO);

        // ensure canvas is resized when window changes size
        window.addEventListener('resize', () => app.resizeCanvas());

        // create box entity
        const box = new pc.Entity('cube');
        box.addComponent('model', {
            type: 'box'
        });
        app.root.addChild(box);

        // create camera entity
        const camera = new pc.Entity('camera');
        camera.addComponent('camera', {
            clearColor: new pc.Color(0.1, 0.1, 0.1)
        });
        app.root.addChild(camera);
        camera.setPosition(0, 0, 3);

        // create directional light entity
        const light = new pc.Entity('light');
        light.addComponent('light');
        app.root.addChild(light);
        light.setEulerAngles(45, 0, 0);

        // rotate the box according to the delta time since the last frame
        app.on('update', dt => box.rotate(10 * dt, 20 * dt, 30 * dt));

        app.start();
    </script>
</body>

How to build

Ensure you have Node.js installed. Then, install all of the required Node.js dependencies:

npm install

Now you can run various build options:

| Command | Description | Outputs | |-----------------------|-------------------------------------------|----------------------------------| | npm run build | Build release, min, debug and profiler engines | build\playcanvas[.min/.dbg/.prf].[mjs/js] | | npm run build:es5 | Build release, min, debug and profiler engines for es5 only | build\playcanvas[.min/.dbg/.prf].js | | npm run build:release | Build release engine for es5 and es6 | build\playcanvas.[mjs/js] | | npm run build:types | Build engine Typescript bindings | build\playcanvas.d.ts | | npm run docs | Build engine API reference docs | docs |

Pre-built versions of the engine are also available.

Latest development release (head revision of dev branch):

https://code.playcanvas.com/playcanvas-latest.js
https://code.playcanvas.com/playcanvas-latest.min.js

Latest stable release:

https://code.playcanvas.com/playcanvas-stable.js
https://code.playcanvas.com/playcanvas-stable.min.js

Specific engine versions:

https://code.playcanvas.com/playcanvas-1.38.4.js
https://code.playcanvas.com/playcanvas-1.38.4.min.js

Generate Source Maps

To build the source map to allow for easier engine debugging, you can add -- -m to any engine build command. For example:

npm run build -- -m

This will output to build/playcanvas.js.map

PlayCanvas Editor

The PlayCanvas Engine is an open source engine which you can use to create HTML5 apps/games. In addition to the engine, we also make the PlayCanvas Editor:
