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.

Project Showcase

Many games and apps have been published using the PlayCanvas engine. Here is a small selection:

You can see more games on the PlayCanvas website.

PlayCanvas Engine and Tools been used by leading companies in game development, automotive, digital agencies and more. Some of them are:
Disney, King, Zynga, Miniclip, Nickelodeon, Leapfrog, IGT, ARM, Samsung, Mozilla, Facebook

Features

The PlayCanvas Engine is a fully featured 3D game engine.

Graphics
- WebGL-based 3D renderer
- Physically based rendering (PBR)
- Directional, point and spot lights (all of which can cast shadows)
- Runtime Lightmap baking
- Static and skinned meshes
- GPU Particle engine with editor
- 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 Assets User Manual
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
- Streaming of individual assets
- Asset Variants - loads compressed textures (DXT, PVR, ETC1) based on platform support
Entity / Component System
- Built-in components: model, sound, animation, camera, collision, light, rigidbody, script, particlesystem
Scripting system
- Write game behaviours by attaching JavaScript to game entities
- Live code hot-swap enables rapid iteration
Input
- Mouse, Keyboard, Touch, Gamepad support, VR

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();
    cube.addComponent("model", {
        type: "box"
    });

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

    // Create directional light entity
    var light = new pc.Entity();
    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 an update event
    app.on("update", function (deltaTime) {
    	  cube.rotate(10 * deltaTime, 20 * deltaTime, 30 * deltaTime);
    });
</script>

How to build

Ensure you have nodejs installed
Ensure you have Java installed.

The first time you build you will be asked to install dependencies using npm. e.g.

npm install fs-extra
npm install google-closure-compiler
npm install preprocessor

Then, to execute a build of the engine to the build/output folder, do:

cd build
node build.js

See the built in help for more build instructions

node build.js -h

Pre-built versions of the engine are also available.
