Class InputTestFixture

A test fixture for writing tests that use the input system. Can be derived from or simply instantiated from another test fixture.

Inheritance

Object

InputTestFixture

Namespace: UnityEngine.InputSystem

Syntax

public class InputTestFixture

Remarks

The fixture will put the input system into a known state where it has only the built-in set of basic layouts and no devices. The state of the system before starting a test is recorded and restored when the test finishes.

public class MyInputTests : InputTestFixture
{
    public override void Setup()
    {
        base.Setup();

        InputSystem.RegisterLayout<MyDevice>();
    }

    [Test]
    public void CanCreateMyDevice()
    {
        InputSystem.AddDevice<MyDevice>();
        Assert.That(InputSystem.devices, Has.Exactly(1).TypeOf<MyDevice>());
    }
}

The test fixture will also sever the tie of the input system to the Unity runtime. This means that while the test fixture is active, the input system will not receive input and device discovery or removal notifications from platform code. This ensures that while the test is running, input that may be generated on the machine running the test will not infer with it.

Set<TValue>(InputControl<TValue>, TValue, Double, Double, Boolean)

Set the control to the given value by sending a state event with the value to the control's device.

Declaration

public void Set<TValue>(InputControl<TValue> control, TValue state, double time = -1, double timeOffset = 0, bool queueEventOnly = false)
    where TValue : struct

Parameters

Type	Name	Description
InputControl<TValue>	control	An input control on a device that has been added to the system.
TValue	state	New value for the input control.
Double	time	Timestamp to use for the state event. If -1 (default), current time is used (see currentTime).
Double	timeOffset	Offset to apply to the current time. This is an alternative to time. By default, no offset is applied.
Boolean	queueEventOnly	If true, no Update() will be performed after queueing the event. This will only put the state event on the event queue and not do anything else. The default is to call Update() after queuing the event. Note that not issuing an update means the state of the device will not change yet. This may affect subsequent Set/Press/Release/etc calls as they will not yet see the state change.

Type Parameters

Name	Description
TValue	Value type of the given control.

Examples

var gamepad = InputSystem.AddDevice<Gamepad>();
Set(gamepad.leftButton, 1);

Set<TValue>(InputDevice, String, TValue, Double, Double, Boolean)

Set the control with the given path on device to the given state by sending a state event with the value to the device.

Declaration

public void Set<TValue>(InputDevice device, string path, TValue state, double time = -1, double timeOffset = 0, bool queueEventOnly = false)
    where TValue : struct

Parameters

Type	Name	Description
InputDevice	device	Device on which to find a control.
String	path	Path of the control on the device.
TValue	state	New state for the control.
Double	time	Timestamp to use for the state event. If -1 (default), current time is used (see currentTime).
Double	timeOffset	Offset to apply to the current time. This is an alternative to time. By default, no offset is applied.
Boolean	queueEventOnly	If true, no Update() will be performed after queueing the event. This will only put the state event on the event queue and not do anything else. The default is to call Update() after queuing the event. Note that not issuing an update means the state of the device will not change yet. This may affect subsequent Set/Press/Release/etc calls as they will not yet see the state change.

Type Parameters

Name	Description
TValue	Value type of the control.

Examples

var device = InputSystem.AddDevice("TestDevice");
Set<ButtonControl>(device, "button", 1);
Set<AxisControl>(device, "{Primary2DMotion}/x", 123.456f);

Setup()

Trigger(InputAction)

Perform the input action without having to know what it is bound to.

Declaration

public void Trigger(InputAction action)

Parameters

Type	Name	Description
InputAction	action	An input action that is currently enabled and has controls it is bound to.

Remarks

Blindly triggering an action requires making a few assumptions. Actions are not built to be able to trigger without any input. This means that this method has to generate input on a control that the action is bound to.

Note that this method has no understanding of the interactions that may be present on the action and thus does not know how they may affect the triggering of the action.

    where TValue : struct
