我的计时器没有停止，我不知道原因 - Actionscript 3

Question

我在阳光下尝试了一切，我无法弄清楚为什么我的计时器拒绝停止运行。如果有人能提供帮助，我将非常感激！鳕鱼如下：

package {
import flash.display.Stage;
import flash.display.MovieClip;
import flash.events.Event;
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.display.Sprite;

public class Monster extends MovieClip
{

    var X:int;
    var Y:int;
    var dodge:Boolean = false;
    var myTween:Tween;
    var myTimer:Timer = new Timer(1000,0);// 1 second
    var alive:Boolean = true;
    var gameWidth = Main.stage.stageWidth;

    public function Monster(X:int, Y:int, whichMonster:Number):void
    {
        myTimer.addEventListener(TimerEvent.TIMER, dodgeAttack);
        if ( whichMonster == 1 )
        {
            myTimer.start();
            trace("Is it running "+myTimer.running);
            level_1(X, Y);
        }
        else if ( whichMonster == 2 )
        {
            myTimer.stop();
            removeEventListener(TimerEvent.TIMER,dodgeAttack);
            trace("Is it still running "+myTimer.running);
            level_2(X, Y);
        }
        else if ( whichMonster == 3 )
        {
            level_3(X, Y);
            trace("Is it running "+myTimer.running);
            myTimer.start();
        }
        else if ( whichMonster == 4 )
        {
            level_4(X, Y);
        }
    }

    public function level_1(X:int, Y:int):int
    {

        this.x = X;
        this.y = Y;
        return X,Y;

    }
    public function level_2(X:int, Y:int):int
    {
        this.x = X;
        this.y = Y;
        //Just hardcode the tweens
        myTween = new Tween(this,"x",Strong.easeOut,this.x,500,1,true);
        myTween.addEventListener(TweenEvent.MOTION_FINISH, onFinish);
        return X,Y;
    }
    public function level_3(X:int, Y:int):int
    {
        this.x = X;
        this.y = Y;
        return X,Y;
    }

    public function level_4(X:int, Y:int):int
    {
        this.x = X;
        this.y = Y;
        return X,Y;
    }

    function onFinish(e:TweenEvent):void
    {
        myTween.yoyo();
    }

    function dodgeAttack(e:TimerEvent):void
    {
        var deflect:int = Math.floor(Math.random() * 5);

        if (deflect == 3)
        {
            this.gotoAndPlay(114);
        }
        else
        {
            trace("It Ran ");
        }
    }

任何帮助将不胜感激！谢谢！
