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
        var canvas = document.getElementById('application');
        var app = new pc.Application(canvas, { });
        app.start();

        // 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', function() {
            app.resizeCanvas();
        });

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

        // create camera entity
        var camera = new pc.Entity('camera');
        camera.addComponent('camera', {
            clearColor: new pc.Color(0.1, 0.1, 0.1)
        });

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

        // add to hierarchy
        app.root.addChild(cube);
        app.root.addChild(camera);
        app.root.addChild(light);

        // set up initial positions and orientations
        camera.setPosition(0, 0, 3);
        light.setEulerAngles(45, 0, 0);

        // register a global update event
        app.on('update', function (deltaTime) {
            cube.rotate(10 * deltaTime, 20 * deltaTime, 30 * deltaTime);
        });
    </script>
</body>

How to build

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

npm install

To execute a build of the engine to build/playcanvas-latest.js, do:

npm run build

Pre-built versions of the engine are also available.

Latest development release:

  • 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

How to get models?

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

How to run tests

PlayCanvas makes use of Karma for running unit tests, and provides three test ways of executing them depending on what phase of development you're in:

# Runs the tests once over the unbuilt source files - useful if you just want a quick 'all-clear'
npm run test

# Watches all source and test files for changes, and automatically re-runs the tests when they change.
# Open http://localhost:9876/debug.html in your browser to debug the tests in real time.
#
# You can also edit the `tests/**/test_*.js` glob in tests/karma.conf.js to run a subset of the tests,
# during development.
npm run test:watch

# Runs the tests once over playcanvas.js - mainly used by CI, but sometimes useful if you want to
# test the engine after building it. Make sure to do `npm run build` first to make sure you have
# an up-to-date build.
npm run test:release

Documentation

Full documentation available on the PlayCanvas Developer site including API reference. To build a local copy of the API reference manual to the docs folder, do:

npm run docs

Tutorials & Examples

See all the tutorials here.

TypeScript Bindings

You can develop TypeScript applications against the PlayCanvas engine. To generate a TypeScript definitions file for the entire API, do:

npm run tsd

This will output to build/output/playcanvas.d.ts
