嗨，我通过在互联网上搜索创建了一个 flash as3 轮播。代码是：

var centerX:Number = stage.stageWidth / 1.7;
var centerY:Number = stage.stageHeight / 2;
var radiusX:Number = 180;
var radiusY:Number = 50;
var speed:Number = 0.1;
var minSpeed:Number = -0.05;
var maxSpeed:Number = 0.05;
var rangeSpeed:Number = maxSpeed - minSpeed;
var minY:Number = centerY - radiusY;
var maxY:Number = centerY + radiusY;
var rangeY:Number = maxY - minY;
var minScale:Number = 0.2;
var maxScale:Number = 1.0;
var rangeScale:Number = maxScale - minScale;
var itemArray:Array = new Array();
itemArray.push(new cubeblue());

itemArray.push(new cubeblue());

itemArray.push(new cubeblue());

itemArray.push(new cubeblue());

itemArray.push(new cubeblue());

itemArray.push(new cubeblue());

var canvas:MovieClip = new MovieClip();
addChild(canvas);

for (var i:Number = 0; i < itemArray.length; i++)
{
    canvas.addChild(itemArray[i]);
    itemArray[i].buttonMode = true;
    itemArray[i].addEventListener(MouseEvent.MOUSE_DOWN, stop);
    itemArray[i].itemAngle = Math.PI * 2 / itemArray.length * i;
    itemArray[i].addEventListener(Event.ENTER_FRAME, animate);
}



function animate(e:Event):void
{
    speed = mouseX / stage.stageWidth * rangeSpeed + minSpeed;
    e.currentTarget.x = Math.cos(e.currentTarget.itemAngle) * radiusX + centerX;
    e.currentTarget.y = Math.sin(e.currentTarget.itemAngle) * radiusY + centerY;
    e.currentTarget.itemAngle += speed;
    itemArray.sortOn("y");

    for(var i:Number = 0; i < itemArray.length; i++)
    {
        canvas.setChildIndex(itemArray[i], i);
        var pct:Number = (itemArray[i].y - minY) / rangeY;
        var scale:Number = pct * rangeScale + minScale;
        itemArray[i].scaleX = itemArray[i].scaleY = scale;
    }
}
function stop(event:MouseEvent):void {


}

现在，经过一些修改，使用停止功能，我想通过单击图层上的一个元素来停止轮播，但我不知道该怎么做！有人可以帮助我吗？

首先，你不能命名一个函数stop，除非你打算重写它，在这种情况下你不是。要停止旋转木马旋转，您只需删除该ENTER_FRAME事件。我将您的stop功能重命名为stopAnimate

var centerX:Number = stage.stageWidth / 1.7;
var centerY:Number = stage.stageHeight / 2;
var radiusX:Number = 180;
var radiusY:Number = 50;
var speed:Number = 0.1;
var minSpeed:Number = -0.05;
var maxSpeed:Number = 0.05;
var rangeSpeed:Number = maxSpeed - minSpeed;
var minY:Number = centerY - radiusY;
var maxY:Number = centerY + radiusY;
var rangeY:Number = maxY - minY;
var minScale:Number = 0.2;
var maxScale:Number = 1.0;
var rangeScale:Number = maxScale - minScale;
var itemArray:Array = new Array();
itemArray.push(new cubeblue());

itemArray.push(new cubeblue());

itemArray.push(new cubeblue());

itemArray.push(new cubeblue());

itemArray.push(new cubeblue());

itemArray.push(new cubeblue());

var canvas:MovieClip = new MovieClip();
addChild(canvas);

for (var i:Number = 0; i < itemArray.length; i++)
{
    canvas.addChild(itemArray[i]);
    itemArray[i].buttonMode = true;
    itemArray[i].addEventListener(MouseEvent.CLICK, stopAnimate);
    itemArray[i].itemAngle = Math.PI * 2 / itemArray.length * i;
    itemArray[i].addEventListener(Event.ENTER_FRAME, animate);
}

function animate(e:Event):void
{
    speed = mouseX / stage.stageWidth * rangeSpeed + minSpeed;
    e.currentTarget.x = Math.cos(e.currentTarget.itemAngle) * radiusX + centerX;
    e.currentTarget.y = Math.sin(e.currentTarget.itemAngle) * radiusY + centerY;
    e.currentTarget.itemAngle += speed;
    itemArray.sortOn("y");

    for(var i:Number = 0; i < itemArray.length; i++)
    {
        canvas.setChildIndex(itemArray[i], i);
        var pct:Number = (itemArray[i].y - minY) / rangeY;
        var scale:Number = pct * rangeScale + minScale;
        itemArray[i].scaleX = itemArray[i].scaleY = scale;
    }
}

function stopAnimate(event:MouseEvent):void
{
    for (var i:Number = 0; i < itemArray.length; i++)
    {
        itemArray[i].removeEventListener(Event.ENTER_FRAME, animate);
    }
}

现在要重新启用动画，您可以简单地添加一个单击事件来让我们说一个按钮，该功能将执行

for (var i:Number = 0; i < itemArray.length; i++)
{
    itemArray[i].addEventListener(Event.ENTER_FRAME, animate);
}

这只会将ENTER_FRAME事件添加回电影剪辑itemArray
