Hey,

If I drew a rectangle on stage using the api drawing methods and say the box was 100x50 in size, what method could I use to increase the size of the box over a period of time so that it appears to grow in size, or indeed shrink in size.

I understand I could simply use a for loop and then increase the width and height accordingly but how would I set the size of the rectangle that I would like the scaling to stop at.

cheers

Any help would be great.

</div>

```auto
scale = function (instance, amount, endscale) {
	if (instance._xscale != endscale) {
		instance._xscale = instance._yscale += amount
		updateAfterEvent ()
	} else {
		clearInterval (scaleInterval)
	}
}

scaleInterval = setInterval (scale, milliseconds, instance, amount, endscale)

```

**milliseconds** number of milliseconds to wait between every execution  
**instance** instance name of the movie clip to scale  
**amount** percentage to scale the movie clip in each execution  
**endscale** final xscale and yscale value

example:

if your movie clip instance name is _rectangle_. you want to increase its scale by 10% each second and the final scale is 200%

```auto
scaleInterval = setInterval (scale, 1000, rectangle, 10, 200)

```

hope it helps 🙂

Careful with this because you won’t necessarily have instance.\_xscale == endscale at some point so it might not stop at all 🙂

</div>

```auto
scale = function (instance, amount, endscale) {
	if (instance._xscale **<** endscale) {
		instance._xscale = instance._yscale += amount
		updateAfterEvent ()
	} else {
		clearInterval (scaleInterval)
	}
}

scaleInterval = setInterval (scale, milliseconds, instance, amount, endscale)

```

happy ?? =)

No: what if you want the clip to shrink? :beam: :beam:

you add a new variable to tell the function what to do 😛
