在闪存AS3中将对象置于最前面

Question

我有下面的代码，它基本上是动画对象在屏幕上，当滚动发生时，它暂停动画，并显示一些信息。一切都很好，但当它暂停时，我希望当前对象“在上面”，这样其他项目就会在后面。

我看过setChildIndex，但没有太多的运气。

package {

import flash.display.MovieClip;
import flash.display.Sprite;
import flash.events.MouseEvent;
import flash.geom.Point;
import flash.events.KeyboardEvent;
import flash.events.*;
import caurina.transitions.Tweener;
import fl.motion.Color;

public class carpurchase extends Sprite {

    public function carpurchase() {

        var carX = 570;


        //Set cars
        var car1:fullCar = new fullCar();
        car1.info.alpha = 0;
        //var c:Color = new Color();
        //c.setTint(0xff0000, 0.8);
        //car2.car.transform.colorTransform=c;
        car1.x = carX;
        car1.y = 280;
        car1.info.title.text = "test";
        car1.info.desc.text = "test";
        addChild(car1);
        car1.addEventListener(MouseEvent.ROLL_OVER, carPause);
        car1.addEventListener(MouseEvent.ROLL_OUT, carContinue);
        function car1Reset():void {
            Tweener.addTween(car1, {x:carX, time:0, onComplete:car1Tween});
        }
        function car1Tween():void {
            Tweener.addTween(car1, {x:-120, time:2, delay:3, transition:"linear", onComplete:car1Reset});
        }
        car1Tween();


        var car2:fullCar = new fullCar();
        car2.info.alpha = 0;
        var c:Color = new Color();
        c.setTint(0xff0000, 0.8);
        car2.car.transform.colorTransform=c;
        car1.x = carX;
        car2.y = 175;
        car2.info.title.text = "test";
        car2.info.desc.text = "test";
        addChild(car2);
        car2.addEventListener(MouseEvent.ROLL_OVER, carPause);
        car2.addEventListener(MouseEvent.ROLL_OUT, carContinue);
        function car2Reset():void {
            Tweener.addTween(car2, {x:carX, time:0, onComplete:car2Tween});
        }
        function car2Tween():void {
            Tweener.addTween(car2, {x:-120, time:3, delay:0, transition:"linear", onComplete:car2Reset});
        }
        car2Tween();



        function carPause(e:MouseEvent):void {
            Tweener.pauseTweens(e.target);
            Tweener.addTween(e.target.info, {y:-150, alpha:1, time:.5, transition:"easeout"});
        }   
        function carContinue(e:MouseEvent):void {
            Tweener.addTween(e.target.info, {y:10, alpha:0, time:.5, transition:"easeout"});
            Tweener.resumeTweens(e.target); 
        }
    }
}

欢迎任何帮助

Answer 1

只需在特定实例上使用addChild()即可。它将被放在“顶部”。

从帮助文件中：

将一个子DisplayObject实例添加到此DisplayObjectContainer实例。该子对象被添加到此DisplayObjectContainer实例中所有其他子对象的前面(顶部)。

是的，即使对象已经在显示列表中，它也是有效的。

你试过setChildIndex吗？

Answer 3

function carPause(e:MouseEvent):void {
    setChildIndex(e.target, numChildren-1);
    Tweener.pauseTweens(e.target);
    Tweener.addTween(e.target.info, {y:-150, alpha:1, time:.5, transition:"easeout"});
}
