Hi,  
how do i can i adjust the Easing property of moving MC when im moving the MC with AS (not with motion tween) ?!

i got an MC and im increasing it’s \_x by 1 till the \_x got to 100.  
how can i adjust the easing, so that when it become close to 100 it will slowly stopped?

anyone?

I´m using Voetsjoeba´s code for easing, but can I apply robert penner´s code´s to it?

Good sample Industriality Thank you! but someone can tell me how to move an object not on x or y but on [FONT=Arial Black][COLOR=Red]diagonal[/COLOR][/FONT]?

> If anyone is interested, I expanded a bit on Voetsjoeba’s code in order to add a “round” attribute, and a “speed” attribute. This is very useful when you need to ease a movieclip that uses Pixel fonts, or fonts that look best on whole pixels. Here are the two functions:
> 
> ```auto
> 
> MovieClip.prototype.easeX = function(to,speed,round){
> this.onEnterFrame = function(){
> if(round!=true){
> this._x += (to - this._x)/speed;
> } else {
> this._x += Math.round((to - this._x)/speed);
> }
> if(this._x > to-1 && this._x < to+1){
> this._x = to;
> delete this.onEnterFrame
> //do other stuff here, this is the point at which the object reaches its target
> }
> }
> }
> MovieClip.prototype.easeY = function(to,speed,round){
> this.onEnterFrame = function(){
> if(round!=true){
> this._y += (to - this._y)/speed;
> } else {
> this._y += Math.round((to - this._y)/speed);
> }
> if(this._y > to-1 && this._y < to+1){
> this._y = to;
> delete this.onEnterFrame
> //do other stuff here, this is the point at which the object reaches its target
> }
> }

> **Usage Examples:**  
> [size=1]mc.easeX(mc.\_x-100,5,true); // Move mc 100 pixels left, on solid pixels, at “5” speed[/size]  
> [size=1]mc.easeX(mc.\_x+100,10,false); // Move mc 100 pixels right, smoothly, at “10” speed[/size]  
> [size=1]mc.easeY(mc.\_y-100,5,true); // Move mc 100 pixels up, on solid pixels, at “5” speed[/size]  
> [size=1]mc.easeY(mc.\_y+100,10,false); // Move mc 100 pixels down, smoothly, at “10” speed[/size]  
> [size=1]mc.easeX(100,5,true); // Move mc to an X of 100, on solid pixels, at “5” speed[/size]  
> [size=1]mc.easeY(100,5,true); // Move mc to a Y of 100, on solid pixels, at “5” speed[/size]  
> [size=1]mc.easeX(100,10,false); // Move mc to an X of 100, smoothly, at “10” speed[/size]  
> [size=1]mc.easeY(100,10,false); // Move mc to a Y of 100, smoothly, at “10” speed[/size]

var easeInKnob =  
var easeOutKnob =  
Was it wrong for me to laugh like a 10-year old schoolboy when I read this?

Maybe it’s just my British sense of humour.
