Hi Rob,
here it is, I’ve included the create_scene and show_scene in case the problem sits there. But basically i detect the movement in the everyframe function. as you will see (commented out) i’ve first tried to detect it with getLinearVelocity but couldnt never get it to zero either.
so i thought i’m gonna force it to wait half a second (3 seconds to test) once it gets through a standstill but it never does on the device.
On the simulator it does work (I have added a touch listener so i can test the ‘facing left or right’ on the simulator) but of course the accelerometer doesnt work on the simulator.
thanks !
