Inherits from NSObject
Declared in KKDeviceMotion.h

Overview

Contains the deviceMotion data. DeviceMotion is only available on devices running iOS 4.0 or newer. The rotationRate and attitude are only available on 4th generation iPhone & iPod touch devices and newer, and iPad 2 and newer.

See the CMDeviceMotion class reference: http://developer.apple.com/library/ios/#documentation/CoreMotion/Reference/CMDeviceMotion_Class/Reference/Reference.html#//apple_ref/doc/c_ref/CMDeviceMotion

Tasks

  •   acceleration

    The KKAcceleration object used by KKDeviceMotion to store user acceleration.

         property
  •   gravity

    The KKAcceleration object used by KKDeviceMotion to store the gravity acceleration vector.

         property
  •   rotationRate

    The KKRotationRate object used by KKDeviceMotion to store the rotation rate reported by gyroscope.

         property
  •   attitude

    Returns the CMAttitude object used by KKDeviceMotion. Is only non-nil when KKInput deviceMotionActive=YES. Contains the attitude as euler angles (roll, pitch, yaw), rotation matrix (CMRotationMatrix), or quaternion (CMQuaternion). On Mac attitude is of type id.

         property
  •   roll

    The roll euler angle of CMAttitude.

         property
  •   pitch

    The pitch euler angle of CMAttitude.

         property
  •   yaw

    The yaw euler angle of CMAttitude.

         property
  • – reset

    Sets all internal values to 0. Call this method after an interruption in your application, for example the pause menu or starting a new level.
