i have a ball i want to move around so i used the following AS to move it:

[AS]

onClipEvent(load) {  
setProperty(this, \_x, 375);  
setProperty(this, \_y, 375);  
moveSpeed = 10;

}

onClipEvent(enterFrame) {

```
if(Key.isDown(key.RIGHT) and this._x &lt; 375) {
	this._x += moveSpeed;
	
	
}
if(key.isDown(key.LEFT) and this._x &gt; 25) {
	this._x -= moveSpeed;
	
}
if(key.isDown(key.UP) and this._y &gt; 25) {
	this._y -= moveSpeed;
}
if(key.isDown(key.DOWN) and this._y &lt; 375) {
	this._y += moveSpeed;
}

```

}

[/AS]

i wanted to add an easing motion, as if it was in water, or something like that so i read a tutorial on easing on this sight and tried…

[AS]

onClipEvent(load) {  
setProperty(this, \_x, 375);  
setProperty(this, \_y, 375);  
moveSpeed = 10;

}

onClipEvent(enterFrame) {

```
if(Key.isDown(key.RIGHT) and this._x &lt; 375) {
	this._x += moveSpeed;
	_x += (endX-_x)/Movespeed;
	
}
if(key.isDown(key.LEFT) and this._x &gt; 25) {
	this._x -= moveSpeed;
	
}
if(key.isDown(key.UP) and this._y &gt; 25) {
	this._y -= moveSpeed;
}
if(key.isDown(key.DOWN) and this._y &lt; 375) {
	this._y += moveSpeed;
}

```

}

[/AS]  
as you can see i only tried it on the right movement, although i wanted it on all movements, but it didn’t really work…  
any help/ pointers in the right direction would be appriciated,  
thanks 🙂

something like:

[AS]  
this.\_x += moveSpeed/2;  
[/AS]

should work. Just change how much you divide it by to get different effects 🙂

you can use endX because it is a variable and you havn’t declared it as anything.

doesn’t seem to give the effect i’m looking for…  
have you ever been to [www.xgenstudios.com/](http://www.xgenstudios.com/)

theres a game there called fishy, you swim this little fish around, and when you go to stop he kind of drifts a little, since you can’t really instantly stop in the water
