I think the family idea will be the answer here! Thanks to both of you.
On a side note, deadeye, just for my clarification, when you said aSprite and bSprite, did you think I had the same sprite as two seperate objects? If so, that was my mistake of clarification. I have a single sprite object placed randomly on the screen, multiple times using a Loop proceedure.
Unfortunantly I don't understand the SOL, or indexed sprites very well, so I will want to do a little research on that tonight. Thanks again guys!
