Flash 如何使用此代码整合GlobalTopolocal？

var maxlenX:int = area_mc.x+area_mc.width;//calculate the maximum x area of our clip. I do this outside the function
// Because the width will change as you move the slider. There are more elegant ways to do this, but I think this is sufficient
// for now. This will be used to stop the slider when it moves all the way to the right of our clip.
function mouseMoveHandler(event:MouseEvent):void {
var topLeft:Point = area_mc.localToGlobal(new Point(0,0));//Translate the top left of the clip into global coords.
var bottomRight:Point = new Point(maxlenX,area_mc.y);//Use the maxlenX variable created above to get the bottom right point. (no need for a point here TBH).
area_mc.sliderbar_mc.x = area_mc.mouseX;
if (mouseX <= topLeft.x){//If the mouse is to the left of the top left point...
area_mc.sliderbar_mc.x = area_mc.globalToLocal(new Point(topLeft.x,topLeft.y)).x;//keep the slider from moving left.
} else if (mouseX >= bottomRight.x){//if the mouse is to the right of the bottom right point...
area_mc.sliderbar_mc.x = area_mc.globalToLocal(new Point(bottomRight.x,bottomRight.y)).x;//keep the slider form moving right.
}
area_mc.mask_mc.x = area_mc.sliderbar_mc.x;//move the mask.
}
var maxlenX:int=area_mc.x+area_mc.width//计算剪辑的最大x面积。我在功能之外做这个
//因为宽度会随着滑块的移动而改变。有更优雅的方法可以做到这一点，但我认为这已经足够了
//现在。这将用于在滑块一直移动到剪辑右侧时停止滑块。
函数mouseMoveHandler（事件：MouseEvent）：void{
var topLeft:Point=area_mc.localToGlobal（新点（0,0））；//将剪辑的左上角转换为全局坐标。
var bottomRight:Point=new Point（maxlenX，area_mc.y）；//使用上面创建的maxlenX变量获取右下角点。（此处不需要点TBH）。
area_mc.sliderbar_mc.x=area_mc.mouseX；
如果（mouseX=bottomRight.x）{//如果鼠标位于右下角点的右侧。。。
area_mc.sliderbar_mc.x=area_mc.globalToLocal（新点（bottomRight.x，bottomRight.y））.x；//保持滑块窗体向右移动。
}
area\u mc.mask\u mc.x=area\u mc.sliderbar\u mc.x；//移动遮罩。
