为什么不把眼睛眨动的图片在baby对象里面初始化呢，这样main是不是显得更清晰？

babyObj.prototype.init = function () {

    this.x = canWidth * 0.5;

    this.y = canHeight * 0.5 ;

    //this.babyEye.src = "src/babyEye0.png";

    this.babyBody.src = "src/babyFade0.png";

    this.angle = 0;

    this.babyTailCount = 0;

    this.babyTailTimer = 0;

    for (var i = 0; i < 8; i++) {

        this.babyTail[i] = new Image();

        this.babyTail[i].src = "src/babyTail" + i + ".png";

    }

    this.babyEyeCount = 0;

    this.babyEyeTimer = 0;

    for (var i = 0; i < 2; i++) {

        this.babyEye[i] = new Image();

        this.babyEye[i].src =  "src/babyEye" + i + ".png";

    }
