I've been writing the content of this tutorial for a couple of weeks now, and I thought I'd submit a relatively brief tutorial on the main components of what I've made so far. I hope you enjoy it, and I hope you can follow all of it. Please leave any critisisms you may have, it's all appreciated. Thanks
Oh and I'm also currently working on more content to put into a second tutorial as a sequel to this one. Leave any ideas you have or anything you want to be put in and I'll work on putting it all in!

good work man =]

good tut, clear, explained the math and all.
only thing is that i am having a problem with the "block"(how do you make the outer part 0% alpha?). the ball wont bounce off of it, rather roll around it,(half way through it).
meh, i am not so good at math(yet).
anyways, good work.(i love seeing the ball bounce =])

you can make the outer section 0% alpha just as part of the colour in the colour panel, alpha is a scroller thing.


A very good Tutorial! Explains everything very clearly and nicely!
