我有一些 AS3（我是新手！），我可以让代码工作的唯一方法是非常文字化并一遍又一遍地复制它，所以我想知道是否有人能够提供更优雅的解决方案？

我保证我会从中吸取教训——我只是无法让 for 循环工作，因为在尝试使用 for 循环中的整数来构建名称时，动态影片剪辑没有被它们的实例名称识别（如果这有意义的话?)...

到目前为止，这是我的（庞大的）代码，我希望它能够满足 50 次点击，而不仅仅是我这里的 6 次：

import flash.display.*

var n:Number = 0;

function addNewPoint(e:MouseEvent):void {
    n++;
    pointNo.text = String(n);
    // Create a new MovieClip
    var nextPoint:MovieClip = new newPoint();

    // Add the new MovieClip to the MainTimeline
    // so that we can see it.
    addChild(nextPoint);
    nextPoint.name = "mc"+pointNo.text;

    // Set the location of the new MovieClip
    nextPoint.x = e.target.mouseX;
    nextPoint.y = e.target.mouseY;

    //Draw the line between points
    if (n == 1) {
        var joinPoints:MovieClip = new MovieClip();
        this.addChild(joinPoints);
        joinPoints.graphics.lineStyle(0.5,0xFF0000);
        joinPoints.graphics.moveTo(this.getChildByName("mc1").x, this.getChildByName("mc1").y);

您可以通过执行以下操作来简化 if：

var joinPoints:MovieClip = new MovieClip();
this.addChild(joinPoints);
joinPoints.graphics.lineStyle(0.5,0xFF0000);
joinPoints.graphics.moveTo(this.getChildByName("mc1").x, this.getChildByName("mc1").y);
for(var i:int=2; i<=numpoints; ++i){
  joinPoints.graphics.lineTo(this.getChildByName("mc"+i).x, this.getChildByName("mc"+i).y);
}

这将处理第一组如果，第二组可以以类似的方式处理
