◆ sceMotionGetState()

int sceMotionGetState ( SceMotionState * motionState )

Gets the current motion state.

Parameters

[out] *motionState - See SceMotionState

Returns: 0, <0 on error.

◆ sceMotionGetSensorState()

int sceMotionGetSensorState	(	SceMotionSensorState *	sensorState,
		int	numRecords
	)

Gets the current motion sensor state.

Parameters

[in]	numRecords	- Amount of records to get
[out]	*motionSensorState	- See SceMotionSensorState

Returns: 0, <0 on error

◆ sceMotionGetDeviceLocation()

int sceMotionGetDeviceLocation ( SceMotionDeviceLocation * deviceLocation )

Gets the location of the device's sensors in relation to its center point (in mm).

Parameters

[out] *deviceLocation - See SceMotionDeviceLocation

Returns: 0, <0 on error

◆ sceMotionGetBasicOrientation()

int sceMotionGetBasicOrientation ( SceFVector3 * basicOrientation )

Gets the basic orientation of the device in relation to gravity.

Note: - Possible values in the output vector are -1, 0 and 1; - Using the same coordinate system as SceMotionDeviceLocation these values are set in the vector depending on if the axies' positive or negative directions are facing away from gravitational pull; - For example if the vita is laying on a flat and level surface, with the OLED/LCD side facing upwards, the Z part of the vector will be 1; - Now flipping the device upwards, taking hold of the right joystick's side, until it forms a 90 degree angle to the surface will result in the X part of the vector being 1 instead; - Both examples would result in the returned value being -1 if flipped 180 degrees, swapping their top and bottom sides in correlation to gravity; - The angle of rotation in relation to being in a centered state on an axis (returned as 0) after which the device will change the value is determined by ::SceMotionSetAngleThreshold; - In order for this function to return up to date data, sceMotionGetState must be called prior to call this function.

Parameters

[out] *basicOrientation

Returns: 0, <0 on error

◆ sceMotionRotateYaw()

Rotate the yaw axis.

Parameters

[in] radians - Rotation angle in radians
