效果

源代码

window.onload = function () {
    var game = new Phaser.Game(800, 600, Phaser.AUTO, 'phaser_container', 
                            preload: preload, create: create, update: update  });

    function preload() {

        game.load.image('ball', 'images/phaser/shinyball.png');

    }

    var balls;

    function create() {

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

        balls = game.add.group();
        balls.enableBody = true;

        for (var i = 0; i < 50; i++) {
            var ball = balls.create(game.world.randomX, game.world.randomY, 'ball');
        }

    }

    function update() {

        if (game.input.mousePointer.isDown) {
            //  第一个参数是回调函数
            //  第二个参数是回调函数对应的上下文，本例中是game.physics.arcade
            balls.forEach(game.physics.arcade.moveToPointer, game.physics.arcade, false, 200);
        }
        else {
            balls.setAll('body.velocity.x', 0);
            balls.setAll('body.velocity.y', 0);
        }
    }
}
