Question

When I click my button I wish one of mc's disapear completely(first alpha changes from 1 to 0) then 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);
}

I dicided to use events but it doesnt work, can anyone help me?

Answer 1

Try moving the aBlend declaration outside of the buttonClickHandler as suggested by this post:

i.e.

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);
}
