Ok so I have two basic questions (I think they are basic :sleep:)

1. I am using the tween class inside a for loop which is inside a function, to alpha fade in some sub menu options. Right now all sub menu options are fading in at the same time and I would like for them to fade in sequentially (i.e. one after the other) So I think what I need to do is pause the for loop and resume when onMotionFinished. But Im not quite sure how to do this. Ive tried using setInterval but I think it is too complicated and I’d rather use the onMotionFinished function since it is more dynamic… How can I do this?

2. I have an integer which might be positive and might be negative, how can I make sure it is ALWAYS positive? Right now I’m doing this:

[AS]  
if (tswLo \< 0){  
tswLo = (tswLo\*(-1));  
}  
[/AS]

But if my memory serves me correctly there is something like int(tswLo) which will convert a negative integer into a positive one, and do nothing to a positive one. What is the function for that?

Thank you!!
