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!



it would be cool if you could play the game


isn't 100fps a little much, as long as a human being already realizes animation at 25fps?

yeah you could say it's a bit overkill, especially if the machine you're using is a bit older. But really I set it to such a high framerate for fluidity - just making it look really smooth no matter how fast the ball goes. Also it helps cos when you reposition the fall when it hits a surface, a high framerate makes that little jump completely invisible.


dude ur one actionscipt/math god... i take additional math at school and u still.. mathified me. btw wats arctan??? i dun think ive learnt abt arc yet? as u can see by teh name I LOVE ACTIONSCRIPT .. but sadly im not that good at it. can ya add me in msn n b my flash tutor =D?

arctan is just the opposite of tan. so if you have x=tan(y), then arctan(x)=y.


well, mostly.

I found that the buttons are annoyingly small, but this is probably an invaluable tutorial for any maker of games.

It would also be a cool game if you could play around with gravity and throw in some wind factors as well, trying to get a ball to a goal. My gr. 12 physics teacher told us that air resistance physics were too compelx for high school, no matter how interested I was in it. I'd like to see some of that in a game if anyone has the ability.


math is a must need in all aspects of making games because a computer is based on math but the concept of your tutorial was there everything that a new programmer would need for a simple touch and go game was built very well ive got nothing but compliments for u good job
