Hi,

I’m having difficulties trying to ease in & out an object which follows the mouse curser.

Basically i’m looking for a delayed (ease out) reaction for when I move the mouse, so when the object finally catches up with the curser it eases in.

Here’s a link to the FLA

[http://www.abreaks.co.uk/foecentre/Example\_5-5a%20rotating%20arrow.fla](http://www.abreaks.co.uk/foecentre/Example_5-5a%20rotating%20arrow.fla)

Here’s the code as well:

stage.addEventListener (Event.ENTER\_FRAME, rotate);  
var xvelocity:Number = 2;  
var yvelocity:Number = 2;  
var vx:Number = 0;  
var vy:Number = 0;  
var thrust:Number = 0.2;  
var myarrow:Arrow = new Arrow();  
myarrow.x = stage.stageWidth/2;  
myarrow.y = stage.stageHeight/2;  
var vr:Number = 5;  
addChild (myarrow);  
myarrow.gotoAndStop (1);

function rotate (evt:Event):void  
{  
var dx:Number = stage.mouseX-myarrow.x;  
var dy:Number = stage.mouseY-myarrow.y;  
var angle:Number = Math.atan2(dy,dx);  
myarrow.rotation = angle\*180/Math.PI;

}

If anyone could help that would be great!

Kind regards,

LM

Well, I don’t have something that does rotation and easing, but I do have something for just easing. I’m sure you can get the gist of it and add it to your script. Here’s the code (credit to _Learning ActionScript 3_):

```auto

var ball:MovieClip = new Ball();
ball.x = ball.y = 100;
addChild(ball);

addEventListener(Event.ENTER_FRAME, onLoop, false, 0, true);
function onLoop(evt:Event):void { 
	ball.x += velFriction(ball.x, mouseX, 8);
	ball.y += velFriction(ball.y, mouseY, 8);
}

function velFriction(orig:Number, dest:Number, coeff:Number):Number {
	return (dest-orig)/coeff;
}

```
