creating properties for sprite

[saveth]

Hi,

I'm trying to create two new properties called startX and startY that I can use with a Sprite.

so when I create

var eachBall:Sprite = Sprite(new AnimateBall());

I can set the property startX and startY like so

eachBall.startX = eachBall.x
eachBall.startY = eachBall.y;

this doesn't need to override the x and y it's just merely a datastore. Any ideas how I can accomplish this?

Thanks,
Saveth
