Usage

<script src="https://github.com/byWulf/threejs-dice/raw/master/lib/dice.js"></script>

<script>
    // Setup your threejs scene
    var scene = new THREE.Scene();
    // ...

    // Setup your cannonjs world
    var world = new CANNON.World();
    // ...

    DiceManager.setWorld(world);

    // Create a dice
    var dice = new DiceD6({backColor: '#ff0000}); //DiceD6 for six-sided dice; for options see DiceObject
    scene.add(dice.getObject());

    // If you want to place the mesh somewhere else, you have to update the body
    dice.getObject().position.x = 150;
    dice.getObject().position.y = 100;
    dice.getObject().rotation.x = 20 * Math.PI / 180;
    dice.updateBodyFromMesh();

    // Set the value of the side, which will be upside after the dice lands
    DiceManager.prepareValues([{dice: dice, value: 6}]);

    //Animate everything
    function animate() {
        world.step(1.0 / 60.0);

        dice.updateMeshFromBody(); // Call this after updating the physics world for rearranging the mesh according to the body

        renderer.render(scene, camera);

        requestAnimationFrame(animate);
    }
    requestAnimationFrame(animate);
