Controller

public class Controller

Class representing a single Daydream controller. Create a Controller using getController(). Optionally register for events with Controller.EventListener. Update the controller's state using update() and then read the public fields as needed.

Nested Classes

class	Controller.BatteryLevels		Constants that represent the controller battery level.
class	Controller.BetaTrackingStatusFlags		Integer bit map for tracking status of one controller in trackingStatusFlags.
class	Controller.ConnectionStates		Constants that represent the controller's states.
class	Controller.EventListener		Listens for various classes of events related to the Controller.

Fields

public boolean	appButtonState	True if the user currently holding down the APP button.
public int	batteryLevelBucket	The current battery level bucket.
public boolean	clickButtonState	True if the user is currently holding the CLICK button down.
public boolean	gripButtonState	True if the user is currently holding down the grip button.
public boolean	homeButtonState	True if the user is currently holding down the HOME button.
public boolean	isCharging	True if the controller is currently being charged.
public boolean	isTouching	True if the user is currently touching the touchpad.
public final Orientation	orientation	The controller's orientation in Start Space as a quaternion.
public final float[]	position	The controller's position for use with elbow model.
public long	timestamp	The time in nanosecond at when the last update occurred.
public final PointF	touch	The normalized coordinates on the touchpad.
public int	trackingStatusFlags	Int field which contains tracking status information of a controller.
public boolean	triggerButtonState	True if the user is currently holding down the trigger button.
public boolean	volumeDownButtonState	True if the user is currently holding the VOLUME DOWN button.
public boolean	volumeUpButtonState	True if the user is currently holding down the VOLUME UP button.

Public Methods

int	getControllerId() Gets the ID that identifies this controller.
float[]	getTransform(float[] output) Combines position and orientation into a matrix.
void	setEventListener(Controller.EventListener listener) Registers an Controller.EventListener for this Controller.
void	update() Update this Controller's state with the latest data from the hardware.

Fields

public boolean appButtonState

True if the user currently holding down the APP button.

public int batteryLevelBucket

The current battery level bucket. This is a value from Controller.BatteryLevels and not the percent.

public boolean clickButtonState

True if the user is currently holding the CLICK button down.

public boolean gripButtonState

True if the user is currently holding down the grip button.

public boolean homeButtonState

True if the user is currently holding down the HOME button.

public boolean isCharging

True if the controller is currently being charged.

public boolean isTouching

True if the user is currently touching the touchpad.

public final Orientation orientation

The controller's orientation in Start Space as a quaternion.

public final float[] position

The controller's position for use with elbow model.

public long timestamp

The time in nanosecond at when the last update occurred. This value is set via update() calls and represents when the last event was received from the hardware.

public final PointF touch

The normalized coordinates on the touchpad. Each value ranges range from [0, 1]. The x value of the touch point aligns with the controller's x-axis, which points to the right of the controller, and the y value aligns with the controller's z-axis. See Controller Space for more information. This is initially (0, 0) until an event is received. If the user is not touching the touchpad, then this is the position of the last touch.

On circular touchpad hardware, the valid touch area will be a 0.5 radius circle centered around (0.5, 0.5).

public int trackingStatusFlags

Int field which contains tracking status information of a controller.

Each bit is defined in Controller.BetaTrackingStatusFlags.

public boolean triggerButtonState

True if the user is currently holding down the trigger button.

public boolean volumeDownButtonState

True if the user is currently holding the VOLUME DOWN button.

public boolean volumeUpButtonState

True if the user is currently holding down the VOLUME UP button.

Public Methods

public int getControllerId ()

Gets the ID that identifies this controller. This corresponds to the index corresponding to the configuration used for this controller in the current TrackingConfiguration's array of controller configurations.

Returns

• the controllerId for this controller.

public float[] getTransform (float[] output)

Combines position and orientation into a matrix.

Parameters

output	16-element array to hold the result.

Returns

• output with elements as a column-major matrix.

public void setEventListener (Controller.EventListener listener)

Registers an Controller.EventListener for this Controller.

Parameters

listener

public void update ()

Update this Controller's state with the latest data from the hardware.
