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

<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">
    body {
        margin: 0;
        overflow: hidden;
<script src="https://code.playcanvas.com/playcanvas-stable.min.js"></script>

<canvas id="application"></canvas>
    // create a PlayCanvas application
    const canvas = document.getElementById('application');
    const app = new pc.Application(canvas);

    // fill the available space at full resolution

    // 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'

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

    // create directional light entity
    const light = new pc.Entity('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));

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, debug and profiler engines |
| |
npm run closure
| Build minified release engine |
| |
npm run tsd
| Build engine Typescript bindings |
| |
npm run docs
| Build engine API reference docs |

Pre-built versions of the engine are also available.

Latest development release (head revision of master 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-0.181.11.js
  • https://code.playcanvas.com/playcanvas-0.181.11.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


Note: The preprocessor is ignored when when generating the source map as it breaks the mapping. This means that all debug and profiling code is included in the engine build when generating the source map.

How to run tests

PlayCanvas uses of Karma for unit testing. There are two ways of running the tests:

| Command | Description | |------------------------|---------------------------------------------------------------------------------------| |

npm run test
| Runs unit tests on a built
| |
npm run test:watch
| Re-runs unit tests when changes are detected - open http://localhost:9876/debug.html |

How to get models?

To convert any models created using a 3D modelling package see this page in the developer documentation.
