Adob​​e Flash AS3掩模放置

Question

我觉得我应该知道这个......好吧，我会喜欢任何帮助。所以我制作了一个图像滑块类，并且可以正常工作到掩码的位置。在我的家庭类中，我制作了一个图像滑块类的实例并相应地定位它。滑块类中的图像位置为0,0以及我用于掩码的形状。这里是掩模放置在stage.x.x = 0，stage.y = 0而不是滑块的Class x：0，x：0的问题。为什么滑块实例显示正确的位置，但实例中的掩码不是？感谢您的帮助

这是我的主页类

private function buildSlider() : void { 
    slider = new Slider(arrSilde); 
    slider.x = btnWidth + 15; 
    addChild(slider); 
    } 

这是Slider类

private var t : Timer; 
    private var counter : int; 

    private var slideArr : Array; 
    private var currentSlide : HomeSliderPageObj; 
    private var oldSlide : HomeSliderPageObj; 

    private var masker : Shape; 


    public function Slider(_arr : Array) { 
    super(); 
    slideArr = _arr; 

    currentSlide = _arr[counter]; 
    buldSlider(); 

    addChild(currentSlide.image); 

    t = new Timer(2000); 
    t.addEventListener(TimerEvent.TIMER, changeSlide); 
    t.start(); 
    } 


    private function buldSlider() : void { 
    masker = new Shape; 
    masker.graphics.lineStyle(); 
    masker.graphics.beginFill(0x000000, 1); 
    masker.graphics.drawRect(0,0, currentSlide.image.width, currentSlide.image.height); 
    masker.graphics.endFill(); 
    masker.x = currentSlide.image.x; 
    masker.y = currentSlide.image.y; 
    this.mask = masker; 
    } 


    private function changeSlide (event : TimerEvent) : void { 
    if (counter >= slideArr.length){ counter = 0; } 
    else { ++counter; } 

    oldSlide = currentSlide as HomeSliderPageObj; 
    addChild(oldSlide.image); 

    removeChild(currentSlide.image); 
    currentSlide = slideArr[counter]; 
    currentSlide.image.x = currentSlide.image.width; 
    addChild(currentSlide.image); 

    TweenMax.to(oldSlide.image, .5, {x:oldSlide.image.width*(-1), onComplete:clean}); 
    TweenMax.to(currentSlide.image, .5, {x:0}); 
    } 


    private function clean() : void { 
    removeChild(oldSlide.image); 
    oldSlide = null; 
    }

见，如果这个工程。

currentSlide = _arr[counter]; 
    buldSlider(); //this creates the mask shape 

    addChild(currentSlide); //this add the image movieclip 
    currentSlide.mask = masker; //this sets the masking 

private function buldSlider() : void { 
    masker = new Shape; 
    masker.graphics.lineStyle(); 
    masker.graphics.beginFill(0x000000, 1); 
    masker.graphics.drawRect(0,0, currentSlide.image.width, currentSlide.image.height); 
    masker.graphics.endFill(); 
    masker.x = currentSlide.image.x; 
    masker.y = currentSlide.image.y; 
    addChild(masker); 
    }
