flash actionscript:
Hello All,
I am using Flash 8 Professional for a real-world pop-up application. I have
isolated a tweening problem that I can not seem to fix and I need to call in
the experts. I have created a very small sample app which demonstrates my
problem.
My stage is 500 x 500.
I've got a movie clip called my_mc which contains a 50 x 50 square. On the
stage, it is located in the lower left-hand corner (the box is registered in
the lower left corner as well).
I've got two other movie clips called findedgex and findedgey. They consist
of a vertical line and a horizontal line respetively. They will be dynamically
positioned to the top edge (findedgey) and right edge (findedgex) of the box
after a tween has been applied to it.
When I roll over the my_mc movieclip, I am tweening it to a random height and
width and then repositioning the findedgex and findedgey lines accordingly.
Am am making the following assumptions ::
The line corresponding to the top edge of the box = my_mc._y - my_mc._height
The line corresponding to the right edge of the box = my_mc._x - my_mc._width
The problem I am having is this -- the width and height properties of my_mc
contain a level of error after the tween has been applied. The greater the
distance of the tween, the greater the level of error. This makes positioning
elements to the top-right corner of the box (ie, a close "X" button) nearly
impossible.
The code for my sample application is as follows ::
========================================
import mx.transitions.Tween;
import mx.transitions.easing.*;
my_mc.onRollOver = function():Void
{
tmpTween = new Tween( my_mc, "_width", None.easeNone, 50, 50+random(400), 6,
false );
tmpTween.onMotionFinished = function()
{
findedgex._x = my_mc._x + my_mc._width;
}
tmpTween = new Tween( my_mc, "_height", None.easeNone, 50, 50+random(400), 6,
false );
tmpTween.onMotionFinished = function()
{
findedgey._y = my_mc._y - my_mc._height;
}
}
my_mc.onRollOut = function():Void
{
tmpTween = new Tween( my_mc, "_width", Strong.easeOut, my_mc._width, 50, 6,
false );
tmpTween.onMotionFinished = function()
{
findedgex._x = my_mc._x + my_mc._width;
}
tmpTween = new Tween( my_mc, "_height", Strong.easeOut, my_mc._height, 50, 6,
false );
tmpTween.onMotionFinished = function()
{
findedgey._y = my_mc._y - my_mc._height;
}
}
findedgex._x = my_mc._x + my_mc._width;
findedgey._y = my_mc._y - my_mc._height;
=============================================
1) Is this a problem with my code or with the Tween class? (I have tried
various easings and they all yeild the same error-result)
2) Any ideas how I can counteract (ie hack) the problem away?
Thanks in advance for your help!
