本质上，产卵船出现在十字准线上方，而我希望它是相反的。我尝试将十字准线添加到另一层，但然后单击/“射击”船只什么也没做。有任何想法吗？

     public class Main extends MovieClip {

        public static var backgroundLayer:Sprite = new Sprite();
        public static var gameLayer:Sprite = new Sprite();

            addChild(interfaceLayer);
            addChild(menuLayer);

            menuLayer.addChild(mainMenu);
            interfaceLayer.addChild(howtoPlay);
            interfaceLayer.addChild(gameEnd);

我希望 MouseDowns 被父层拦截。你已经mouseEnabled=false为十字准线工作了，现在你应该为它的父母做这件事。

public static var crosshairLayer:Sprite=new Sprite();
public function Main() {
    ... // initialize everything first
    addChild(gameLayer);
    addChild(crosshairLayer);
    crosshairLayer.mouseEnabled=false;
    crosshairLayer.mouseChildren=false;
}

然后将十字准线添加到crosshairLayer.
