Syntax
public class GravitySensor : Sensor
Remarks

A gravity sensor let's you determine the direction of the gravity vector relative to a device, and can be useful to control content by device orientation. This is usually derived from a hardware Accelerometer, by subtracting the effect of linear acceleration (see LinearAccelerationSensor).

Properties

current

The gravity sensor that was last added or had activity last.

Declaration
public static GravitySensor current { get; }
Property Value
Type Description
GravitySensor

Current gravity sensor or null.

Vector3Control

Methods

FinishSetup()

Perform final initialization tasks after the control hierarchy has been put into place.

Declaration
protected override void FinishSetup()
Overrides
Remarks

This method can be overridden to perform control- or device-specific setup work. The most common use case is for looking up child controls and storing them in local getters.

public class MyDevice : InputDevice
{
    public ButtonControl button { get; private set; }
    public AxisControl axis { get; private set; }

    protected override void OnFinishSetup()
    {
        // Cache controls in getters.
        button = GetChildControl("button");
        axis = GetChildControl("axis");
    }
}

MakeCurrent()

Make this the current device of its type.

Declaration
public override void MakeCurrent()
Overrides
Remarks

This method is called automatically by the input system when a device is added or when input is received on it. Many types of devices have .current getters that allow querying the last used device of a specific type directly (for example, see current).

There is one special case, however, related to noise. A device that has noisy controls (i.e. controls for which noisy is true) may receive input events that contain no meaningful user interaction but are simply just noise from the device. A good example of this is the PS4 gamepad which has a built-in gyro and may thus constantly feed events into the input system even if not being actually in use. If, for example, an Xbox gamepad and PS4 gamepad are both connected to a PC and the user is playing with the Xbox gamepad, the PS4 gamepad would still constantly make itself current by simply flooding the system with events.

By enabling filterNoiseOnCurrent (disabled by default), noise on .current getters will be filtered out and a device will only see MakeCurrent getting called if there input was detected on non-noisy controls.

OnRemoved()

Called by the system when the device is removed from devices.

Declaration
protected override void OnRemoved()
Overrides
Remarks

This is called after the device has already been removed.
