源代码

window.onload = function () {
    var game = new Phaser.Game(600, 400, Phaser.AUTO, 'phaser_container', 
                            { preload: preload, create: create, update: update, render: render });                                

    function preload() {
        game.load.image('arrow', 'images/phaser/arrow.png');
    }

    var sprite;

    function create() {

        game.physics.startSystem(Phaser.Physics.ARCADE);

        game.stage.backgroundColor = '#0072bc';

        sprite = game.add.sprite(400, 300, 'arrow');
        sprite.anchor.setTo(0.5, 0.5);

        //  对箭头开启Arcade物理系统
        game.physics.enable(sprite, Phaser.Physics.ARCADE);

        //  物理系统不处理箭头body的旋转
        sprite.body.allowRotation = false;

    }

    function update() {

        sprite.rotation = game.physics.arcade.moveToPointer(sprite, 60, game.input.activePointer, 500);

    }

    function render() {

        game.debug.spriteInfo(sprite, 32, 32);

    }
}
