Calibration of Accelerometer

Does anyone know if there is a wiki out there that explains how a user can recalibrate the accelerometer from in game?

Or at least how to give the player the option of a couple of different angles (0, 45, 60 for example)

I'm at work so I don't have my project in front of me, but I'm doing this in both my Z and V games.

It's not too difficult, just requires a few attributes. I created two attributes called calibratedX and calibratedY.

I then have a button called calibrate that has a rule on it, when touched it sets game.calibratedX to game.accelerometerX. Same thing for calibratedY.

then just update your move rules to use those values instead of the stock -0.1 or 0.1

I'll try and move my code into a sample project tonight.

Awesome thanks a lot mulcahy. A sample game with the calibration would be amazing. Love Z by the way I bought it yesterday in the app store.
