PlayCanvas WebGL Game Engine
PlayCanvas is an open-source game engine. It uses HTML5 and WebGL to run games and other interactive 3D content in all modern browsers without the need for a plugin.
Published Games and Demos
Many games have been published using the PlayCanvas engine. Here is a small selection.
You can see more games on the PlayCanvas website.

- WebGL-based 3D renderer
- Directional, point and spot lights (all of which can cast shadows)
- Static and skinned meshes
- Keyframed animation support
- Particle engine with editor
- Physically based rendering (PBR)
- PostFX library: bloom, edge detect, FXAA, vignette, etc
- Seamless default material support from Maya, 3DS Max, Blender, etc.
- Full model export pipeline from Maya, 3DS Max, Blender, etc via PlayCanvas Tools
- Collision & Physics
- Full integration with 3D rigid-body physics engine ammo.js
- Audio
- 3D Positional audio via Web Audio API
- Resource Loading
- Simple and powerful resource loading
- Entity / Component System
- Built-in components: audiosource, animation, camera, collision, light, rigidbody, script
- Scripting system
- Write game behaviours by attaching JavaScript to game entities.
- Input
- Mouse, Keyboard, Touch, Gamepad support
Usage
Here's a super-simple Hello World example - a spinning cube!
<script>
// Create a PlayCanvas application
var canvas = document.getElementById("application-canvas");
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);
// Create box entity
var cube = new pc.Entity();
app.context.systems.model.addComponent(cube, {
type: "box"
});
// Create camera entity
var camera = new pc.Entity();
app.context.systems.camera.addComponent(camera, {
clearColor: new pc.Color(0.1, 0.1, 0.1)
});
// Create directional light entity
var light = new pc.Entity();
app.context.systems.light.addComponent(light);
// Add to hierarchy
app.context.root.addChild(cube);
app.context.root.addChild(camera);
app.context.root.addChild(light);
// Set up initial positions and orientations
camera.setPosition(0, 0, 3);
light.setEulerAngles(45, 0, 0);
// Register an update event
app.on("update", function (deltaTime) {
cube.rotate(10 * deltaTime, 20 * deltaTime, 30 * deltaTime);
});
</script>
