AS3循環實例名稱+ i

Question

我有一些AS3（我是新手！），唯一可以讓代碼工作的方式是非常直接的，並且一遍又一遍地重複它，所以我想知道是否有人能夠提供更優雅的解決方案嗎？

我保證我會從中學習 - 我只是無法得到一個for循環工作，因爲當試圖使用for循環中的整數來構建名稱時動態影片剪輯未被它們的實例名稱識別（ ？如果是有道理的）...

這裏是我的（大件）代碼，到目前爲止，我希望它滿足這50次不只是6我這裏有：

import flash.display.* 
pic.addEventListener(MouseEvent.CLICK,addNewPoint); 

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

Answer 1

你可以通過做簡化IFS：

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); 
} 

，將採取第一組IF的照顧，第二個可以用類似的方式處理
