I have completely re-written and posted the tutorial covering scrolling a 2D background on my site . This tutorial has been upgraded with improved code and art assets and is now completely re-written for the XNA 2.0 framework.
I have also take the time to create a more advanced version of the source code. I tend to target beginners with my site so I don't always make my code as "robust" as it could be. Often, it teaches a concept, but it's not easy to reuse in another project. The advanced version of the code attempts to delve a little deeper into just how you might structure your code in a more object oriented approach for future reuse. Both the simpler and advanced versions of the code are available as separate source code downloads.
Head on over and check out the tutorial on Scrolling a 2D Background.
As always, I'm *BEGGING* for some comments and feedback. Seriously, even if it's just to say "Hi!". I love to hear from people that have read the tutorials and enjoyed them or even from people that didn't enjoy them. If you have some advice to give on how I should improve, I'd love to hear that too. And of course, if they're helping you out, I'd love to hear that as well. Just a couple comments can really make a difference in helping me stay motivated so if you have a few seconds, just take a little time, I really appreciate them!
