Actionscript 3 使用数组中剪辑的名称将Circle添加到现有movieclip

我目前正在建设一个项目，我有一个地图与一些船舶和飞机。我试图实现的是检查它们之间的视线距离。 我设置了一个服务水平计算器，它检查一个站台的高度和第二个站台的高度，然后给出响应。那很好

然后我想根据这个计算器的结果添加Circle。因此，如果结果是10，它将画一个半径为10厘米的圆。如果结果是100，那么它将在100绘制它，你得到了图片。这很有效

我现在的问题是，我需要能够在计算之前或之后单击一个平台，并将.addCircle添加到该movieClip中。我已经设置了一个数组来存储movieclips实例名，并对其进行了跟踪。我在舞台上添加了一个字段，这样你可以点击一个平台，它会识别点击的平台。我只是不知道如何让圆圈进入已点击的电影唇

我对AS3很陌生，所以这开始困扰我。任何帮助都将不胜感激

我的代码附在下面。我希望我已经正确地插入了这个。再次感谢

// creation of array containing movieclips and code that adds the clicked movieclip to Array-platformClicked
var platformArray:Array = [arunta_mc, f15_mc];
var platformClicked = [];
var selectedPlatform:MovieClip = new MovieClip();

for(var i:int = 0; i < platformArray.length; i++) {
    platformArray[i].buttonMode = true;

导入flash.events.MouseEvent；
导入flash.display.MovieClip；

对于（变量i:int=0；i

您可以使用

过滤器（）

方法检查每个项目的名称，如下所示：

var selectedPlatformArray:Array = platformArray.filter(checkName);

var selectedPlatform:MovieClip = stage.getChildByName(platformClicked);

在代码的某个地方，定义

checkName

函数

function checkName(item:MovieClip, index:int, array:Array):Boolean
{
    return (item.name == platformClicked);
}

selectedPlatformArray

现在将包含

checkName

函数返回

true

的所有元素，并且只要没有多个同名的

MovieClips

，数组就应该只包含一个元素，只需访问数组的第一个元素即可检索：

var selectedPlatform:MovieClip = selectedPlatformArray[0];

或者，您也可以使用

getChildByName（）

函数，如下所示：

var selectedPlatformArray:Array = platformArray.filter(checkName);

var selectedPlatform:MovieClip = stage.getChildByName(platformClicked);

但是，这取决于对象添加到的位置，如果它们不都在同一个容器中（或者根本不添加），那么这不是最好的选择。不过，对于小型项目来说，这是一个快速而简单的解决方案

无论如何，无论使用何种方法，您都可以像往常一样在

equalHandler

函数中轻松地将圆添加到圆中：

selectedPlatform.addChild(newCircle);

我建议查看和的文档，以便更好地了解它们是如何工作的，因为我的示例仅显示了在这种特定情况下如何使用它们

完成您应该拥有的代码：

for(var i:int = 0; i < platformArray.length; i++) {
    platformArray[i].buttonMode = true;
