How to use this action script?

Hi.

I´ve got on robert penners web site some exemples of action script for ease and elastic movement. here is one of the codes I´m trying to apply on a movie to start.

class com.robertpenner.easing.Elastic {
	static function easeIn (t:Number, b:Number, c:Number, d:Number, a:Number, p:Number):Number {
		if (t==0) return b;  if ((t/=d)==1) return b+c;  if (!p) p=d*.3;
		if (!a || a < Math.abs(c)) { a=c; var s=p/4; }
		else var s = p/(2*Math.PI) * Math.asin (c/a);
		return -(a*Math.pow(2,10*(t-=1)) * Math.sin( (t*d-s)*(2*Math.PI)/p )) + b;
	}
	static function easeOut (t:Number, b:Number, c:Number, d:Number, a:Number, p:Number):Number {
		if (t==0) return b;  if ((t/=d)==1) return b+c;  if (!p) p=d*.3;
		if (!a || a < Math.abs(c)) { a=c; var s=p/4; }
		else var s = p/(2*Math.PI) * Math.asin (c/a);
		return (a*Math.pow(2,-10*t) * Math.sin( (t*d-s)*(2*Math.PI)/p ) + c + b);
	}
	static function easeInOut (t:Number, b:Number, c:Number, d:Number, a:Number, p:Number):Number {
		if (t==0) return b;  if ((t/=d/2)==2) return b+c;  if (!p) p=d*(.3*1.5);
		if (!a || a < Math.abs(c)) { a=c; var s=p/4; }
		else var s = p/(2*Math.PI) * Math.asin (c/a);
		if (t < 1) return -.5*(a*Math.pow(2,10*(t-=1)) * Math.sin( (t*d-s)*(2*Math.PI)/p )) + b;
		return a*Math.pow(2,-10*(t-=1)) * Math.sin( (t*d-s)*(2*Math.PI)/p )*.5 + c + b;
	}
}
{

Could someone point me some way of usage of theses codes? where to put them? or point me some tutorials or threads?

Thanks

Do you use Flash MX or Flash MX 2004?

If you use Flash MX 2004 then there is an easier way, they have their own built in Tween class.

I´m using 2004.
Don´t know it very much. It´s brand new.

How is that easy way???

Thanks

There is a class in Flash MX 2004 that’s undocumented. Called the tween class.

These are the type of effects it can create linear movement, bounce effect, elastic effect, and more :smiley:

By having abit of code you can create any of the above effect, provided that your also using a function or similar.

Thanks

I´ll take a look at that.
