AS3.0等到补间完成

Question

当我点击我的按钮时，我希望其中一个mc完全消失（第一个alpha从1变为0）然后removeChild。

import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
main.btn.addEventListener(MouseEvent.CLICK, buttonClickHandler);

function buttonClickHandler(event:MouseEvent):void 
{

var aBlend = new Tween(main, "alpha", Strong.easeOut, 1, 0, 3, true);

aBlend.addEventListener(TweenEvent.MOTION_FINISH, end);   //doesnt work
}
function end()
{
    this.removeChild(mc);
}

我决定使用活动，但它不起作用，任何人都可以帮助我吗？

Answer 1

尝试按照此帖子的建议在buttonClickHandler之外移动aBlend声明：

即

import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
main.btn.addEventListener(MouseEvent.CLICK, buttonClickHandler);

var aBlend;

function buttonClickHandler(event:MouseEvent):void 
{

aBlend = new Tween(main, "alpha", Strong.easeOut, 1, 0, 3, true);

aBlend.addEventListener(TweenEvent.MOTION_FINISH, end);   //doesnt work
}
function end(event:TweenEvent)
{
    this.removeChild(mc);
}
