Hi,

i’ve got a cool scrolling function, that i often (always ;-)) use  
( because it’s a simple and easy to adapting to Y, X, scale…) :  
\*  
[COLOR=Red]function scrolling(nom, coord, coef) {  
nom.onEnterFrame = function() {  
this.\_x += (coord-this.\_x)\*coef;  
if (this.\_x == coord) {  
delete this.onEnterFrame;  
}  
};  
}[/COLOR]

\*I want to add to this function an elastic effect…but as i’m not a head in physic, maybe someone can help me ?

thanks !
