If you want to use a class like this:
MyClass.myMethod(myargs)
Then the myMethod function in MyClass should be defined as static. So instead
of:
public class MotionBlur
{
public static function coordBlur(mc:MovieClip, blurFactor:Number = 1.5)
{
//logic here
}
}
And there is no need for the constructor, since you're not using it in the
class, and the class is meant to have all static members.

Subject: [Flashcoders] Class syntax question...
Hi cool list,
I want to make a Class that contains MotionBlur methods that I can call like
this: MotionBlur.coordBlur(mc, 1.5);
I have other classes wich I don't initiate and just call static methods from.
The MotionBlur class looks like this:
public class MotionBlur
{
public function MotionBlur()
{
// empty, never initiated
}
public static function coordBlur( mc :MovieClip, blurFactor
:Number = 1.5 ) :void
{
// calculate blur and apply blur setting to mc
}
public static function clearBlur( mc :MovieClip ) :void
{
// clear blur setting on mc
}
}
Ideally I want to use this through TweenMax like this:
TweenMax.from(mc, .4, {
alpha: 0, x: 1500, delay: 2, ease: Back.easeOut,
onUpdate: MotionBlur.coordBlur,
onUpdateParams: [mc, 1.5],
onComplete:
MotionBlur.clearBlur, onCompleteParams: [mc], overwrite: false
} );
But I get the following error: (even if I just call the method outside tweenmax
like this MotionBlur.coordBlur(chick, 2);)
1120: Access of undefined property MotionBlur.
I'm not quit sure what is going wrong here... does anyone see something strange
that I'm totally missing?
