FLash：尝试使用setChildIndex和TweenLite创建按钮翻转效果时出错

（来源：）

大家好：）所以今天我尝试在按钮翻转上创建一个简单的发光效果。我可能把事情复杂化了，但我要做的是有两个movieClips（默认状态和过度状态）

首先，我将默认状态添加到stage，然后，我将滚动状态添加到stage，但深度为0，alpha也设置为0。现在，我希望滚动状态与默认状态交换深度，并使用TweetLite类设置完整alpha的动画，以便获得良好的平滑过渡

我现在收到一个错误，但下面是我的代码：

import gs.TweenLite;
import fl.motion.easing.*;
import flash.display.MovieClip;


var shopButton:MovieClip;
var shopButtonRoll:MovieClip;
var maxIndex:Number = this.numChildren - 1;

// Button - places the default state onto the stage
shopButton = new ShopButton();
shopButton.name = "shopButton";
shopButton.x = 262;
shopButton.y = 207;
shopButton.stop();
thumbsMov.addChild(shopButton);

// Button Glow - places rollOver state under the default and with 0 alpha
shopButtonRoll = new ShopButtonRoll();
shopButtonRoll.name = "shopButtonRoll";
shopButtonRoll.x = 262;
shopButtonRoll.y = 207;
shopButtonRoll.alpha = 0;
thumbsMov.addChildAt(shopButtonRoll, 0);

// Listeners

shopButton.addEventListener(MouseEvent.MOUSE_UP, shopClick);
shopButton.addEventListener(MouseEvent.ROLL_OVER, sendToTop);
shopButton.addEventListener(MouseEvent.ROLL_OUT, shopOff);
shopButtonRoll.addEventListener(MouseEvent.ROLL_OVER, shopOver);

// Button Actions 
// shopOver should bring rollOver to top and animate to 100%

function shopOver(event:MouseEvent):void
{
     TweenLite.to(shopButtonRoll, 1, {alpha:1});
}
function shopOff(event:MouseEvent):void
{
     // Code to animate back to 0 then change depth of rollOver to 0
}
function shopClick(event:MouseEvent):void
}
     trace("You clicked Shop");
}

// sendToTop Function
// Sent to top - depth change
function sendToTop(e:Event):void
{
     //this.setChildIndex(ShopButton(e.target), maxIndex);
     this.setChildIndex(e.currentTarget as MovieClip, maxIndex);
}

我在翻滚时遇到的错误：（

ArgumentError:Error#2025:提供的DisplayObject必须是调用者的子对象。 在flash.display:：DisplayObjectContainer/setChildIndex（）处 测试时佛罗里达州：：主时间线/sendToTop（）

我不明白所提供的DisplayObject必须是调用者的子对象所导致的错误意味着什么？

根据您的尝试，您不必管理深度。基本上，您只需在shopButton中添加翻转效果，然后在翻转shopButton后，设置发光动画。我使用以下命令编辑了代码罗恩：

import gs.TweenLite;
import fl.motion.easing.*;
import flash.display.MovieClip;


var shopButton:MovieClip;
var shopButtonRoll:MovieClip;

// Button - places the default state onto the stage
shopButton = new ShopButton();
shopButton.name = "shopButton";
shopButton.x = 262;
shopButton.y = 207;
shopButton.stop();
thumbsMov.addChild(shopButton);

// Button Glow - places rollOver state under the default and with 0 alpha
shopButtonRoll = new ShopButtonRoll();
shopButtonRoll.name = "shopButtonRoll";
shopButtonRoll.alpha = 0;
shopButton.addChild(shopButtonRoll);


// Listeners
shopButton.buttonMode = true;
shopButton.addEventListener(MouseEvent.MOUSE_UP, shopClick);
shopButton.addEventListener(MouseEvent.ROLL_OVER, shopOver);
shopButton.addEventListener(MouseEvent.ROLL_OUT, shopOff);

// Button Actions 
// shopOver should bring rollOver to top and animate to 100%

function shopOver(event:MouseEvent):void
{
     TweenLite.to(shopButtonRoll, 1, {alpha:1});
}
function shopOff(event:MouseEvent):void
{
    TweenLite.to(shopButtonRoll, 1, {alpha:0});
     // Code to animate back to 0 then change depth of rollOver to 0
}
function shopClick(event:MouseEvent):void
}
     trace("You clicked Shop");
}

根据您尝试完成的内容，您不必管理深度。基本上，您只需在shopButton中添加滚动效果，然后在滚动shopButton后，设置发光动画。我使用以下内容编辑了您的代码：

import gs.TweenLite;
import fl.motion.easing.*;
import flash.display.MovieClip;


var shopButton:MovieClip;
var shopButtonRoll:MovieClip;

// Button - places the default state onto the stage
shopButton = new ShopButton();
shopButton.name = "shopButton";
shopButton.x = 262;
shopButton.y = 207;
shopButton.stop();
thumbsMov.addChild(shopButton);

// Button Glow - places rollOver state under the default and with 0 alpha
shopButtonRoll = new ShopButtonRoll();
shopButtonRoll.name = "shopButtonRoll";
shopButtonRoll.alpha = 0;
shopButton.addChild(shopButtonRoll);


// Listeners
shopButton.buttonMode = true;
shopButton.addEventListener(MouseEvent.MOUSE_UP, shopClick);
shopButton.addEventListener(MouseEvent.ROLL_OVER, shopOver);
shopButton.addEventListener(MouseEvent.ROLL_OUT, shopOff);

// Button Actions 
// shopOver should bring rollOver to top and animate to 100%

function shopOver(event:MouseEvent):void
{
     TweenLite.to(shopButtonRoll, 1, {alpha:1});
}
function shopOff(event:MouseEvent):void
{
    TweenLite.to(shopButtonRoll, 1, {alpha:0});
     // Code to animate back to 0 then change depth of rollOver to 0
}
function shopClick(event:MouseEvent):void
}
     trace("You clicked Shop");
}

谢谢！我不再犯那个错误了，但仍然看不到我的Tween动画…嗯，谢谢！我不再犯那个错误了，但是仍然看不到我的Tween动画…嗯，谢谢
