代码：

var config = {
    type: Phaser.AUTO,
    width: 720,
    height: 520,
    backgroundColor: '#2d2d2d',
    parent: 'phaser-example',
    scene: {
        preload: preload,
        create: create
    }
};

var game = new Phaser.Game(config);

function preload() {

    this.load.image('racecar', 'assets/racecar.png');
}

function create() {
    // 1.每个节点
    var points = [
        50, 300, 179, 449, 394, 498, 593, 455,
        701, 338, 692, 190, 603, 76, 423, 41,
        272, 78, 181, 186, 230, 328, 416, 395,
        565, 327, 550, 202, 467, 149, 355, 164,
        343, 254, 428, 303
    ];

    //2.连结每一个节点
    var curve = new Phaser.Curves.Spline(points);

    //3.画线(可视化 非必须) optional
    var graphics = this.add.graphics();
    graphics.lineStyle(1, 0xffffff, 0.5);
    curve.draw(graphics, 128);
    graphics.fillStyle(0xff0000, 0.5);
    for (var i = 0; i < curve.points.length; i++) {
        graphics.fillCircle(curve.points[i].x, curve.points[i].y, 4);
    }
    //4. 创建racing car
    var lemming = this.add.follower(curve, 50, 300, 'racecar').setScale(0.3);
   //5.让 racing car 跟随path
    lemming.startFollow({
        duration: 10000,
        yoyo: false,
        repeat: 0,
        rotateToPath: true,
        verticalAdjust: true
    });
