Odd or Even number in ActionScript

I was making a project for a client of mine where I had to make a list with two different colors for the items (like the iTunes list) so I started to think of a possible way to make this. It was clear enough I need to know the odd or the even number in order to do that. So I started to do some google search and I got over this blogpost by Keith Peters. I have to say, this is a very interesting way of thinking 😀

iseven = ((num & 1) == 0)

Makes sense when you look at binary numbers:

001 = 1
010 = 2
011 = 3
100 = 4
101 = 5

Each of the odd numbers has a 1 in the far right column. The even numbers have 0 there. Mask it with “& 1″ and you can see which it is.

So I made a for loop and used this code. It works exactly how it was intended to work!!
Thanks Keith Peters for your blogpost 😀

New book

I just got my new ActionScript 3.0 book.
This book was reviewed by Lee Brimelow on theFlashBlog.com and I thought I should try it because I’m still trying to learn AS 3.0
From what I see right now the book is great! It is full-color and the code looks real 😀
So, thank you Lee for letting us know about this book 😉
