如何在翻转事件上更改光标

我要点一下，然后单击带有Flash的AS3中的游戏。

通过创建新的类“ Souris”，我改变了光标的外观。工作正常。现在，我正在尝试更改光标在场景中某个对象上时的外观。

我读过MouseEvent.ROLL_OVER是个好方法，但是我不知道该怎么做...

我有这样的Souris课：

    public class Souris extends MovieClip
    {
 private var engine:Engine;
        private var stageRef:Stage;
        private var p:Point = new Point(); 

        public function Souris(stageRef:Stage)
        {
            Mouse.hide(); //make the mouse disappear
            mouseEnabled = false; //don't let our cursor block anything
mouseChildren = false;

            this.stageRef = stageRef;
            x = stageRef.mouseX;
            y = stageRef.mouseY;

            stageRef.addEventListener(MouseEvent.MOUSE_MOVE, updateMouse, false, 0, true);
            stageRef.addEventListener(Event.MOUSE_LEAVE, mouseLeaveHandler, false, 0, true);
            stageRef.addEventListener(Event.ADDED, updateStack, false, 0, true);
            stageRef.addEventListener(MouseEvent.ROLL_OVER,hover);

        }

        private function updateStack(e:Event) : void
        {
            stageRef.addChild(this);
        }
        private function hover(e:MouseEvent):void {
               souris.visible = false;
            }

        private function mouseLeaveHandler(e:Event) : void
        {
            visible = false;
            Mouse.show(); //in case of right click
            stageRef.addEventListener(MouseEvent.MOUSE_MOVE, mouseReturnHandler,    false, 0, true);
        }

        private function mouseReturnHandler(e:Event) : void
        {
            visible = true;
            Mouse.hide(); //in case of right click
            removeEventListener(MouseEvent.MOUSE_MOVE, mouseReturnHandler);
        }

        private function updateMouse(e:MouseEvent) : void
        {
            x = stageRef.mouseX;
            y = stageRef.mouseY;

            e.updateAfterEvent();
        }

    }

}
}

在我的主班（发动机班）中，我有：

private var souris:Souris;

public function Engine(){



                        souris = new Souris(stage);
            stage.addChild(souris);

        }
private function startGame(e:Event):void{
....
..

我试图参加“ Souris”课程

stageRef.addEventListener(MouseEvent.ROLL_OVER,hover);

private function hover(e:MouseEvent):void {
Engine.souris.visible = false; 
handCursor.visible = true ;
}

但这似乎是错误的...我不知道要在悬停功能中添加什么。（我的图书馆里有“ handCursor”）。

非常感谢您的帮助！
