GvrControllerInput

Main entry point for the Daydream controller API.

Summary

To use this API, add this script to a game object in your scene, or use the GvrControllerMain prefab. This is a singleton object. There can only be one object with this script in your scene.

To access a controller's state, get a device from GvrControllerInput.GetDevice then query it for state. For example, to the dominant controller's current orientation, use GvrControllerInput.GetDevice(GvrControllerHand.Dominant).Orientation.

Events

OnControllerInputUpdated

static Action OnControllerInputUpdated

Event handler for receiving button, touchpad, and IMU updates from the controllers.

Use this handler to update app state based on controller input.

OnPostControllerInputUpdated

static Action OnPostControllerInputUpdated

Event handler for receiving a second notification callback, after all OnControllerInputUpdated events have fired.

Properties

Accel

static Vector3 Accel

Gets the dominant controller's current acceleration in meters per second squared.

Deprecated. Replaced by GvrControllerInputDevice.Accel.

The controller's axes are:

• X points to the right.
• Y points perpendicularly up from the controller's top surface.
• Z lies along the controller's body, pointing towards the front.

Note that gravity is indistinguishable from acceleration, so when the controller is resting on a surface, expect to measure an acceleration of 9.8 m/s^2 on the Y axis. The accelerometer reading will be zero on all three axes only if the controller is in free fall, or if the user is in a zero gravity environment like a space station.

The acceleration. Will be Vector3.zero if GvrControllerInput is uninitialized.

Gets a value indicating whether this is the frame the user started pressing down the dominant controller's app button.

Deprecated. Replaced by GvrControllerInputDevice.GetButtonDown(GvrControllerButton.App).

Value true if this is the frame the user started pressing down the dominant controller's app button, false otherwise.

AppButtonUp

static bool AppButtonUp

Gets a value indicating whether this is the frame after the user stopped pressing down the dominant controller's app button.

Deprecated. Replaced by GvrControllerInputDevice.GetButtonUp(GvrControllerButton.App).

Returns false if GvrControllerInput is uninitialized. Every AppButtonUp event is guaranteed to be preceded by exactly one AppButtonDown event in an earlier frame. Also, AppButtonDown and AppButtonUp will never both be true in the same frame.

Value true this is the frame the user started pressing down the dominant controller's touchpad button, false otherwise.

ClickButtonUp

static bool ClickButtonUp

Gets a value indicating whether this is the frame after the user stops pressing down the dominant controller's touchpad button.

Value true if this is the frame after the user stops pressing down the dominant controller's touchpad button, false otherwise.

ErrorDetails

static string ErrorDetails

Gets details about the reasoning behind the Dominant Controller's error state.

Deprecated. Replaced by GvrControllerInputDevice.ErrorDetails.

Orientation

static Quaternion Orientation

Gets the dominant controller's current orientation in space, as a quaternion.

Deprecated. Replaced by GvrControllerInputDevice.Orientation.

The rotation is provided in 'orientation space' which means the rotation is given relative to the last time the user recentered their controllers. To make a game object in your scene have the same orientation as the dominant controller, simply assign this quaternion to the object's transform.rotation. To match the relative rotation, use transform.localRotation instead.

The orientation. This is Quaternion.identity if GvrControllerInput is uninitialized.

Recentered

static bool Recentered

Gets a value indicating whether the user just completed the recenter gesture.

Returns false if GvrControllerInput is uninitialized. The headset and the dominant controller's orientation are now being reported in the new recentered coordinate system. This is an event flag (it is true for only one frame after the event happens, then reverts to false).

Value true if the user has just finished recentering, false otherwise.

Deprecated. Replaced by GvrControllerInputDevice.GetButtonDown(GvrControllerButton.TouchPadTouch).

Returns false if GvrControllerInput is uninitialized. Every TouchDown event is guaranteed to be followed by exactly one TouchUp event in a later frame. Also, TouchDown and TouchUp will never both be true in the same frame.

Value true if this is the frame after the user starts touching the dominant controller's touchpad, false otherwise.

TouchPos

static Vector2 TouchPos

Gets the position of the dominant controller's current touch, if touching the touchpad.

Deprecated. Please migrate to the center-relative GvrControllerInputDevice.TouchPos.

Returns Vector2(0.5f, 0.5f) if GvrControllerInput is uninitialized. If not touching, this is the position of the last touch (when the finger left the touchpad). The X and Y range is from 0 to 1. (0, 0) is the top left of the touchpad and (1, 1) is the bottom right of the touchpad.
