• 🔌 Entity Component System - Write efficent and extendable code.
• 🔊 Sound - 3D positional sounds built on the Web Audio API.
• 📜 Scripts - Design game behaviors in JavaScript.
• ⚡ Performance - Taro is a thin framework on top of three.js.

Documentation

You can find the Taro documentation on the website.

Usage

There are several examples on the website. Here is an example to get started:

var app = new TARO.App();
document.body.appendChild( app.domElement );

var scene = new TARO.Scene();
app.setScene(scene);

class CubeController {
  init() {
    // fires when the component is attached to an entity
    this.rotation = this.entity.rotation;
  }

  update() {
    // fires once per frame
    this.rotation.x += 0.01;
    this.rotation.y += 0.01;
  }
}

TARO.registerComponent('cubeController', CubeController);

var cube = new TARO.Entity('cube');
cube.addComponent('material', { color: 0x00ff00 });
cube.addComponent('geometry', { type: 'box' });
cube.addComponent('cubeController');

var camera = new TARO.Entity('camera');
camera.position.z = 5;
camera.addComponent('camera');

app.start();

This example will display a spinning cube on the canvas.
