I've got a tilt-controlled game, locked to landscape mode (DispFixRot=2) - and I've noticed that in some cases the screen turns upside down, with a relatively small amount of tilt.
This is a bit of a problem for a tilt-to-steer game...
- Marmalade 6.0.5
- IwGL app on iOS
- DispFixRot = 2
Hold the device in landscape mode, with the home button on the *left*
Rotate the device slowly, as if turning a steering wheel, either counter-clockwise or clockwise.
At around 45 degrees (iPhone 4) or 70 degrees (iPad 3), the screen flips upside down - much earlier than expected.
(If you hold the device with the home button on the *right*, it doesn't flip until you rotate well beyond 90 degrees)
