well...

...i think the point that you cant really understand (cos the text eas too small sometimes n it was fast pased in other parts was part of the humour...unless it was a serious tut, then im confussed! lol

Useless

Devoid of anything more than a small (and very basic) code snippet, this "tutorial" is pretty useless. Spiff it up with methods of how to change the speed using variables, add things like acceleration, friction, gravity and so forth, and you'll have something that can be of use to people.

Furthermore: When writing a tutorial, make sure not to make it simply a source for a quick copy-paste job. Writing up the code in small, well-explained portions (with a small exercise in the end, perhaps) is best.

I gave this a zero, because in my opinion, it's useless. That code you provided can be easily found in tutorials on other websites, on the BBS, and through a small bit of studying. Try again with a more complete and comprehensive tutorial.
