Hi, great tutorial, very nice job. However, I can’t deal with a transposition for my own needs. And NOBODY (yes, i said NOBODY) on the web seems to understand something and explains about vectors, except you ^^

I’m sure that my study case should be easy for you, so if you would help me a little on this, it would be very nice

If so, send me a PM or email me at ivico92@free.fr (I’d like to talk about my project in privacy ^^)

Thank you, bye bye

[...] I have found a good tutorial on the subject of making a ball move based on the accelerometer: Exploring iPhone Graphics Part 3 | Trails in the Sand but the motion of the ball does not look nearly as smooth as other apps I have seen (Labyrinth is [...]

Great tutorials, thanks! I have a question though. No matter how I play with the values here the motion of the ball doesn’t feel exactly right. I want it to be nice and smooth the way apps like “Labyrinth” on the app store are. Do you have any recommendations on how to adapt this code to make it like that, or are they using an entirely different algorithm do you think? Thanks!

That’s great. Thank you!
