Question

我是Action Script的新手，并且非常困惑我为什么会出现堆栈溢出。我将发布所有3个课程（相关内容）。我得到的输出。有人可以向我解释为什么这会导致堆栈溢出吗？

Main Class:

        public function Main() {
            //Problem starts here
            player1 = new Player();
            player2 = new Player();
// More code that does not matter
        }

玩家等级：

package  {

    import fl.motion.Color;
    import flash.display.MovieClip;

    public class Player extends MovieClip {

        public function Player() {
            var index:Finger = new Finger();
            var middle:Finger = new Finger();
            var ring:Finger = new Finger();
            var pinkie:Finger = new Finger();
        }
    }   
}

手指类：

package  {

    public class Finger extends Player {

        var colorOn:String;

        public function Finger(){
            colorOn = ""
        }

        function SetColor(colour:String):void {
            this.colorOn = colour;
        }
    }
}

输出：

Is this where stack overflow accuros?
Error: Error #1023: Stack overflow occurred.

Answer 1

要创建Player，您需要创建四个新Finger个对象...但每个Finger对象也是Player（因为Finger扩展Player）。因此，创建这四个Finger对象中的每一个都需要创建四个 more Fingers等...因此堆栈溢出。

。最简单的方法可能是阻止Finger延长Player - 您确定应该这样做吗？
