Sorry, my post got cut off (firefox on mac bug)
here's the rest of the code:
private function getRGBArray(hex:Number):Array
{
// get red by shifting hex effectively rounding it down
var r = (hex>>16);
var remains = hex - (r<<16);
// get green by shifting the red-remains
var g = (remains>>8);
// get green by subtracting the greenvalue from the
red-remains
var b = remains - (g<<8);
return [r,g,b];
}
private function onTweenEnd(t:TweenEvent):void
{
//null
}
// define update function
private function onTweenUpdate(t:TweenEvent):void
{
var o:Object = (t.target as
SmartTextInput).getStyle('backgroundColor');
var a:Array = getRGBArray((o as Number));
// c is an [r,g,b]-array
// shift the values to position and add them to get the
color value.
var c:ColorTransform = new
ColorTransform(((a[0]+1)<<16)+((a[1]+1)<<8)+(a[2]+1));
(t.target as
SmartTextInput).setStyle('backgroundColor', c);
}
Do I need to be extending TweenEffect and using that? Or, do I need to
be extending Tween? I'm a little confused how these work beyond the
simple mxml examples in the docs.
