Question

我在as3上创建了一个DragDrop类。我试图制作可移动的电影剪辑＆＃34;坚持＆＃34;到目标MovieClip。我已经获得了基本的拖拽和定位/坚持工作但是当我尝试创建一个＆＃34;缓和＆＃34;使用输入帧效果，不知何故，影片剪辑移动到0 x和y位置。

以下是正常工作的代码（没有EnterFrame事件）。

for cell in worksheet.get_cell_collection():
   print(cell.value)

这里的代码不起作用（使用EnterFrame事件）。

package {
    public class DragDrop {
        public var clip:MovieClip;
        public var targ:MovieClip;
        public var myHomeX:Number;
        public var myHomeY:Number;
        public var myFinalX:Number;
        public var myFinalY:Number;

        public function selectClip(clipV:MovieClip,targV:MovieClip):void {
            clip = clipV;
            targ = targV;
            var myHomeX = clip.x;
            var myHomeY = clip.y;
            var myFinalX = targ.x;
            var myFinalY = targ.y;

            clip.addEventListener(MouseEvent.MOUSE_DOWN,startDragging);
            clip.addEventListener(MouseEvent.MOUSE_UP,stopDragging);
            clip.addEventListener(MouseEvent.ROLL_OVER,rollOver);
            clip.addEventListener(MouseEvent.ROLL_OUT,rollOut);

            function startDragging(e:MouseEvent):void {
                clip.startDrag();
                clip.beingDragged = true;
                clip.parent.setChildIndex(clip,clip.parent.numChildren - 1);
            }

            function stopDragging(e:MouseEvent):void {
                clip.stopDrag();
                clip.beingDragged = false;
                var onTarget:MovieClip;
                if (clip.dropTarget != null)
                {
                    onTarget = e.target.dropTarget.parent;
                }
                else
                {
                    onTarget = null;
                } 
                if ((onTarget == targ))
                {
                    clip.onTarget = true;
                    targ.gotoAndStop(2);
                    clip.x = myFinalX;
                    clip.y = myFinalY;
                }
                else
                {
                    clip.onTarget = false;
                    targ.gotoAndStop(1);
                    clip.x = myHomeX;
                    clip.y = myHomeY;
                }
            }

            function rollOver(e:MouseEvent) {
                clipGlow.restart();
            }

            function rollOut(e:MouseEvent) {
                clipGlow.reverse();
            }
        }
    }
}

提前感谢您的帮助。：）

如果你这样做：

var myHomeX = clip.x;
var myHomeY = clip.y;
var myFinalX = targ.x;
var myFinalY = targ.y;

那么也许clip.myHomeX应该只是myHomeX等？

function slide(e:Event):void {
            if (! clip.beingDragged && ! clip.onTarget)
            {
                clip.x -=  clip.x -myHomeX / 5;
                clip.y -=  clip.y -myHomeY / 5;
                clip.scaleX +=  (1 - clip.scaleX) / 5;
                clip.scaleY +=  (1 - clip.scaleY) / 5;
            }
            else if (! clip.beingDragged && clip.onTarget)
            {
                clip.x -=  clip.x -myFinalX / 5;
                clip.y -=  clip.y -myFinalY / 5;
                clip.scaleX +=  (1.5 - clip.scaleX) / 5;
                clip.scaleY +=  (1.5 - clip.scaleY) / 5;
            }
        }
