Migrating from the old input system

This guide provides a list of APIs in UnityEngine.Input (and other related APIs in UnityEngine) and their corresponding APIs in the new Input System. Not all APIs have a corresponding version in the new API yet.

Note: All of the new APIs are in the UnityEngine.InputSystem namespace. The namespace is omitted here for brevity. UnityEngine.InputSystem is referenced in full for easy disambiguation.

Note that it is possible to have code for the old and the new input system at the same time using conditional compilation. When the new input system is enabled in the player preferences (see here), the ENABLE_INPUT_SYSTEM preprocessor directive is available.

#if ENABLE_INPUT_SYSTEM
    // New input system backends are enabled.
#endif

#if ENABLE_LEGACY_INPUT_MANAGER
    // Old input backends are enabled.
#endif

    // NOTE: Both can be true at the same time as it is possible to select "Both"
    //       under "Active Input Handling".

`UnityEngine.Input`

`UnityEngine.Input.acceleration`

Use Accelerometer.current.acceleration.ReadValue().

`UnityEngine.Input.accelerationEventCount`

See UnityEngine.Input.accelerationEvents.

`UnityEngine.Input.accelerationEvents`

Acceleration events aren't made available separately from other input events. The following code traces all input events on the Accelerometer.current device.

    private InputEventTrace trace;

    void StartTrace()
    {
        InputSystem.EnableDevice(Accelerometer.current);

        trace = new InputEventTrace(Accelerometer.current);
        trace.Enable();
    }

    void Update()
    {
        foreach (var e in trace)
        {
            //...
        }
        trace.Clear();
    }

`UnityEngine.Input.anyKey`

Use InputSystem.onAnyButtonPress.

InputSystem.onAnyButtonPress
    .CallOnce(ctrl => Debug.Log($"Button {ctrl} pressed!"));

`UnityEngine.Input.anyKeyDown`

Use Keyboard.current.anyKey.wasUpdatedThisFrame

`UnityEngine.Input.backButtonLeavesApp`

No corresponding API yet.

`UnityEngine.Input.compass`

No corresponding API yet.

    var compositionString = "";
    Keyboard.current.onIMECompositionChange += composition =>
    {
        compositionString = composition.ToString();
    };

`UnityEngine.Input.deviceOrientation`

No corresponding API yet.

`UnityEngine.Input.gyro`

The UnityEngine.Gyroscope class is replaced by multiple separate sensor Devices in the new Input System:

Gyroscope to measure angular velocity.
GravitySensor to measure the direction of gravity.
AttitudeSensor to measure the orientation of the device.
Accelerometer to measure the total acceleration applied to the device.
LinearAccelerationSensor to measure acceleration applied to the device, compensating for gravity.

`UnityEngine.Input.gyro.attitude`

Use AttitudeSensor.current.orientation.ReadValue().

`UnityEngine.Input.gyro.enabled`

// Get:
Gyroscope.current.enabled

// Set:
InputSystem.EnableDevice(Gyroscope.current);
InputSystem.DisableDevice(Gyroscope.current);

Note: The new Input System replaces UnityEngine.Gyroscope with multiple separate sensor devices. Substitute Gyroscope with other sensors in the sample as needed. See UnityEngine.Input.gyro section for details.

`UnityEngine.Input.gyro.gravity`

Use GravitySensor.current.gravity.ReadValue().

`UnityEngine.Input.gyro.rotationRate`

Use Gyroscope.current.angularVelocity.ReadValue().

`UnityEngine.Input.gyro.rotationRateUnbiased`

No corresponding API yet.

`UnityEngine.Input.gyro.updateInterval`

Use Sensor.samplingFrequency:

Gyroscope.current.samplingFrequency = 1.0f / updateInterval;

Note:

samplingFrequency is in Hz, not in seconds as updateInterval, so you need to divide 1 by the value.

The new Input System replaces UnityEngine.Gyroscope with multiple separate sensor devices. Substitute Gyroscope with other sensors in the sample as needed. See UnityEngine.Input.gyro for details.

`UnityEngine.Input.gyro.userAcceleration`

Use LinearAccelerationSensor.current.acceleration.acceleration.ReadValue().

`UnityEngine.Input.imeCompositionMode`

No corresponding API yet.

`UnityEngine.Input.imeIsSelected`

// Get:
Keyboard.current.imeSelected

// Set:
Keyboard.current.SetIMEEnabled(true);

`UnityEngine.Input.inputString`

Subscribe to the Keyboard.onTextInput event:

Keyboard.current.onTextInput +=
    character => /* ... */;

`UnityEngine.Input.location`

No corresponding API yet.

`UnityEngine.Input.mousePosition`

Use Mouse.current.position.ReadValue().

Note: Mouse simulation from touch isn't implemented yet.

`UnityEngine.Input.mousePresent`

Use Mouse.current != null.

`UnityEngine.Input.multiTouchEnabled`

No corresponding API yet.

`UnityEngine.Input.simulateMouseWithTouches`

No corresponding API yet.

`UnityEngine.Input.stylusTouchSupported`

No corresponding API yet.

`UnityEngine.Input.touchCount`

Use InputSystem.EnhancedTouch.Touch.activeTouches.Count

Note: Enable enhanced touch support first by calling InputSystem.EnhancedTouchSupport.Enable().

`UnityEngine.Input.touches`

Use InputSystem.EnhancedTouch.Touch.activeTouches.

Note: Enable enhanced touch support first by calling InputSystem.EnhancedTouch.Enable().

`UnityEngine.Input.touchPressureSupported`

No corresponding API yet.

`UnityEngine.Input.touchSupported`

Use Touchscreen.current != null.

`UnityEngine.Input.GetAccelerationEvent`

See UnityEngine.Input.accelerationEvents.

`UnityEngine.Input.GetAxis`

There is no global setup that corresponds exactly to virtual axis setups in the old Input Manager settings. Instead, you can create sets of Input Actions as independent Assets, or put them directly on your C# components.

For example, if you want to recreate the following axis configuration:

Option A: Put Input Actions on your component

Declare one or more fields of type InputAction.

    public class MyComponent : MonoBehaviour
    {
        public InputAction fireAction;

Configure a response to the Action.

        void Awake()
        {
            fireAction.performed += ctx => Fire();
        }

        void Fire()
        {
            //...
        }

Put the component on a GameObject. You can now configure Bindings in the Inspector window. Click the plus sign on the Bindings list to add Bindings, and double-click the Bindings to pick Controls to bind to.

Enable and disable the Action as needed.

        void OnEnable()
        {
            fireAction.Enable();
        }

        void OnDisable()
        {
            fireAction.Disable();
        }

Option B: Create an Input Action Asset

Create an Input Action Asset (right-click in the Project browser and select Create > Input Actions). Give the Asset a name.
Double-click the Asset to open the Input Actions editor window.
In the Action Maps column, click the plus sign to add a new Action Map.
Double-click the New Action Map name to rename the set. Use a descriptive name, such as gameplay.
In the Actions column, click the plus sign to add a new Action.
Double-click the Action to give it a name.
Add Bindings to the Action. To do this, click the plus sign on the Action and choose a Binding type from the list.
Select the Binding and click on the Path button in the right column to pick Controls to bind to.
Click Save Asset. Your Input Action editor should now look like this:
Check the Generate C# Wrapper Class checkbox in the Inspector window for the Asset, then click Apply. Your Inspector should now look like this:

Add an instance of the generated C# wrapper class to your component.

public class MyComponent : MonoBehaviour
{
    MyControls controls;

Create the instance and hook up a response to the fire Action.

    public void Awake()
    {
        controls = new MyControls();
        controls.gameplay.fire.performed += ctx => Fire();
    }

Enable and disable the Action as appropriate.

    public void OnEnable()
    {
        controls.Enable();
    }

    public void OnDisable()
    {
        controls.Disable();
    }

Hints

To force button-like behavior on the control referenced in a Binding, add a press Interaction to it.

You can access the Control that triggered an Action from the callback. Through it, you can also query its current value.

fireAction.performed +=
    ctx =>
    {
        var control = ctx.control; // Grab control.
        var value = ctx.GetValue<float>(); // Read value from control.

        // Can do control-specific checks.
        var button = control as ButtonControl;
        if (button != null && button.wasPressedThisFrame)
            /* ... */;
    }

`UnityEngine.Input.GetAxisRaw`

Not directly applicable. You can use InputControl<>.ReadUnprocessedValue() to read unprocessed values from any control.

`UnityEngine.Input.GetButton`

Use InputAction.IsPressed.

if (playerInput.actions["fire"].IsPressed() && Time.time - m_LastFireTime >= kFireRate)
    Fire();

`UnityEngine.input.GetButtonDown`

Use InputAction.WasPressedThisFrame.

if (playerInput.actions["fire"].WasPressedThisFrame())
    Fire();

`UnityEngine.input.GetButtonUp`

Use InputAction.WasReleasedThisFrame.

if (playerInput.actions["fire"].WasReleasedThisFrame())
    StopFiring();

`UnityEngine.Input.GetJoystickNames`

There is no API that corresponds to this exactly.

Here are various ways to discover connected Devices:

// Query a list of all connected Devices (does not allocate; read-only access).
InputSystem.devices

// Get notified when a Device is added or removed.
InputSystem.onDeviceChange +=
    (device, change) =>
    {
        if (change == InputDeviceChange.Added || change == InputDeviceChange.Removed)
        {
            Debug.Log($"Device '{device}' was {change}");
        }
    }

// Find all gamepads and joysticks.
var devices = InputSystem.devices;
for (var i = 0; i < devices.Count; ++i)
{
    var device = devices[i];
    if (device is Joystick || device is Gamepad)
    {
        Debug.Log("Found " + device);
    }
}

`UnityEngine.Input.GetKey`

Use ButtonControl.isPressed on the corresponding key:

// Using KeyControl property directly.
Keyboard.current.spaceKey.isPressed
Keyboard.current.aKey.isPressed // etc.

// Using Key enum.
Keyboard.current[Key.Space].isPressed

// Using key name.
((KeyControl)Keyboard.current["space"]).isPressed

Note: The Input System identifies keys by physical layout, not according to the current language mapping of the keyboard. To query the name of the key according to the language mapping, use KeyControl.displayName.

`UnityEngine.Input.GetKeyDown`

Use ButtonControl.wasPressedThisFrame on the corresponding key:

// Using KeyControl property directly.
Keyboard.current.spaceKey.wasPressedThisFrame
Keyboard.current.aKey.wasPressedThisFrame // etc.

// Using Key enum.
Keyboard.current[Key.Space].wasPressedThisFrame

// Using key name.
((KeyControl)Keyboard.current["space"]).wasPressedThisFrame

Note: The Input System identifies keys by physical layout, not according to the current language mapping of the keyboard. To query the name of the key according to the language mapping, use KeyControl.displayName.

`UnityEngine.Input.GetKeyUp`

Use ButtonControl.wasReleasedThisFrame on the corresponding key:

// Using KeyControl property directly.
Keyboard.current.spaceKey.wasReleasedThisFrame
Keyboard.current.aKey.wasReleasedThisFrame // etc.

// Using Key enum.
Keyboard.current[Key.Space].wasReleasedThisFrame

// Using key name.
((KeyControl)Keyboard.current["space"]).wasReleasedThisFrame

Note: The Input System identifies keys by physical layout, not according to the current language mapping of the keyboard. To query the name of the key according to the language mapping, use KeyControl.displayName.

`UnityEngine.Input.GetMouseButton`

Use ButtonControl.isPressed on the corresponding mouse button:

Mouse.current.leftButton.isPressed
Mouse.current.rightButton.isPressed
Mouse.current.middleButton.isPressed

// You can also go through all buttons on the mouse (does not allocate).
var controls = Mouse.current.allControls;
for (var i = 0; i < controls.Count; ++i)
{
    var button = controls[i] as ButtonControl;
    if (button != null && button.isPressed)
        /* ... */;
}

// Or look up controls by name.
((ButtonControl)Mouse.current["leftButton"]).isPressed

`UnityEngine.Input.GetMouseButtonDown`

Use ButtonControl.wasPressedThisFrame on the corresponding mouse button:

Mouse.current.leftButton.wasPressedThisFrame
Mouse.current.rightButton.wasPressedThisFrame
Mouse.current.middleButton.wasPressedThisFrame

`UnityEngine.Input.GetMouseButtonUp`

Use ButtonControl.wasReleasedThisFrame on the corresponding mouse button:

Mouse.current.leftButton.wasReleasedThisFrame
Mouse.current.rightButton.wasReleasedThisFrame
Mouse.current.middleButton.wasReleasedThisFrame

`UnityEngine.Input.GetTouch`

Use InputSystem.EnhancedTouch.Touch.activeTouches[i]

Note: Enable enhanced touch support first by calling InputSystem.EnhancedTouch.Enable().
