Question

我正在尝试让我的游戏在按下按钮时更改光标。然而，在按下其中一个按钮后，我无法再次更改它（好像光标挡住了）。我想设置mouseCursor.mouseEnabled = false; 会解决它，但似乎没有。这是我的代码，有人可以告诉我，我做错了吗？

package
{
    import flash.display.MovieClip;
    import flash.events.*;
    import flash.geom.*;
    import flash.text.*;
    import flash.utils.*;
    import flash.ui.*;

import Game.*;

public class GameController extends MovieClip
{
    private var mouseCursor:MovieClip;

    public function GameController()
    {

    }

    private function followMouse(evt:Event)
    {
        mouseCursor.x = mouseX;
        mouseCursor.y = mouseY;
    }

    public function startGame()
    {   
        needleOn = false;

        mcGameUI.btnMixBlue.addEventListener(
                MouseEvent.CLICK, mixBlue);

        mcGameUI.btnMixRed.addEventListener(
                MouseEvent.CLICK, mixRed);

        mcGameUI.btnMixYellow.addEventListener(
                MouseEvent.CLICK, mixYellow);

        mcGameUI.btnNeedle.addEventListener(
                MouseEvent.CLICK, activateNeedle);


        mcGameUI.mouseEnabled = false;
    }       

    private function mixBlue(evt:MouseEvent)
    {
        if (mouseCursor != null)
        {
            removeChild(mouseCursor);
            mouseCursor.removeEventListener(Event.ENTER_FRAME,followMouse);         
            mouseCursor = null;
        }
            mouseCursor = new BlueBubble(mouseX,mouseY);
            mouseCursor.gotoAndPlay("idle");
            mouseCursor.mouseEnabled = false;
            mouseCursor.addEventListener(Event.ENTER_FRAME,followMouse);            
            addChild(mouseCursor);
    }
    private function mixRed(evt:MouseEvent)
    {
        if (mouseCursor != null)
        {
            removeChild(mouseCursor);
            mouseCursor.removeEventListener(Event.ENTER_FRAME,followMouse);         
            mouseCursor = null;
        }
            mouseCursor = new RedBubble(mouseX,mouseY);
            mouseCursor.gotoAndPlay("idle");
            mouseCursor.mouseEnabled = false;
            mouseCursor.addEventListener(Event.ENTER_FRAME,followMouse);            
            addChild(mouseCursor);
    }
    private function mixYellow(evt:MouseEvent)
    {
        if (mouseCursor != null)
        {
            removeChild(mouseCursor);
            mouseCursor.removeEventListener(Event.ENTER_FRAME,followMouse);         
            mouseCursor = null;
        }
            mouseCursor = new YellowBubble(mouseX,mouseY);
            mouseCursor.gotoAndPlay("idle");
            mouseCursor.mouseEnabled = false;
            mouseCursor.addEventListener(Event.ENTER_FRAME,followMouse);            
            addChild(mouseCursor);
    }

    private function activateNeedle(evt:MouseEvent)
    {
        if (mouseCursor != null)
        {
            removeChild(mouseCursor);
            mouseCursor = null;
            mouseCursor.removeEventListener(Event.ENTER_FRAME,followMouse);         
        }
        mouseCursor = new Needle();
        mouseCursor.mouseEnabled = false;
        addChild(mouseCursor);
        mouseCursor.addEventListener(Event.ENTER_FRAME,followMouse);            

    }


}   
}

你应该设置：

mouseCursor.mouseEnabled = false;
mouseCursor.mouseChildren = false;

mouseEnabled仅关闭容器mouseCursor，但在此剪辑中，您仍然可以使用mouseEnabled元素，因此也应关闭mouseChildren。

mouseChildren在DisplayObjectContainer中定义，这意味着由形状或位图构成的游标将不具有此属性，因此您需要先测试它是否存在。

if(mouseCursor is DisplayObjectContainer){
{
    mouseCursor.mouseChildren = false;
}
