Property Descriptions
---------------------

.. _class_InputEvent_property_device:

- :ref:`int<class_int>` **device**

+-----------+-------------------+
| *Default* | ``0``             |
+-----------+-------------------+
| *Setter*  | set_device(value) |
+-----------+-------------------+
| *Getter*  | get_device()      |
+-----------+-------------------+

The event's device ID.

**Note:** This device ID will always be ``-1`` for emulated mouse input from a touchscreen. This can be used to distinguish emulated mouse input from physical mouse input.

Method Descriptions
-------------------

.. _class_InputEvent_method_accumulate:

- :ref:`bool<class_bool>` **accumulate** **(** :ref:`InputEvent<class_InputEvent>` with_event **)**

Returns ``true`` if the given input event and this input event can be added together (only for events of type :ref:`InputEventMouseMotion<class_InputEventMouseMotion>`).

The given input event's position, global position and speed will be copied. The resulting ``relative`` is a sum of both events. Both events' modifiers have to be identical.

----

.. _class_InputEvent_method_as_text:

- :ref:`String<class_String>` **as_text** **(** **)** |const|

Returns a :ref:`String<class_String>` representation of the event.

----

.. _class_InputEvent_method_get_action_strength:

- :ref:`float<class_float>` **get_action_strength** **(** :ref:`String<class_String>` action, :ref:`bool<class_bool>` exact_match=false **)** |const|

Returns a value between 0.0 and 1.0 depending on the given actions' state. Useful for getting the value of events of type :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>`.

If ``exact_match`` is ``false``, it ignores the input modifiers for :ref:`InputEventKey<class_InputEventKey>` and :ref:`InputEventMouseButton<class_InputEventMouseButton>` events, and the direction for :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>` events.

----

.. _class_InputEvent_method_is_action:

- :ref:`bool<class_bool>` **is_action** **(** :ref:`String<class_String>` action, :ref:`bool<class_bool>` exact_match=false **)** |const|

Returns ``true`` if this input event matches a pre-defined action of any type.

If ``exact_match`` is ``false``, it ignores the input modifiers for :ref:`InputEventKey<class_InputEventKey>` and :ref:`InputEventMouseButton<class_InputEventMouseButton>` events, and the direction for :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>` events.

----

.. _class_InputEvent_method_is_action_pressed:

- :ref:`bool<class_bool>` **is_action_pressed** **(** :ref:`String<class_String>` action, :ref:`bool<class_bool>` allow_echo=false, :ref:`bool<class_bool>` exact_match=false **)** |const|

Returns ``true`` if the given action is being pressed (and is not an echo event for :ref:`InputEventKey<class_InputEventKey>` events, unless ``allow_echo`` is ``true``). Not relevant for events of type :ref:`InputEventMouseMotion<class_InputEventMouseMotion>` or :ref:`InputEventScreenDrag<class_InputEventScreenDrag>`.

If ``exact_match`` is ``false``, it ignores the input modifiers for :ref:`InputEventKey<class_InputEventKey>` and :ref:`InputEventMouseButton<class_InputEventMouseButton>` events, and the direction for :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>` events.

**Note:** Due to keyboard ghosting, :ref:`is_action_pressed<class_InputEvent_method_is_action_pressed>` may return ``false`` even if one of the action's keys is pressed. See `Input examples <https://docs.godotengine.org/en/3.4/tutorials/inputs/input_examples.html#keyboard-events>`__ in the documentation for more information.

----

.. _class_InputEvent_method_is_action_released:

- :ref:`bool<class_bool>` **is_action_released** **(** :ref:`String<class_String>` action, :ref:`bool<class_bool>` exact_match=false **)** |const|

Returns ``true`` if the given action is released (i.e. not pressed). Not relevant for events of type :ref:`InputEventMouseMotion<class_InputEventMouseMotion>` or :ref:`InputEventScreenDrag<class_InputEventScreenDrag>`.

If ``exact_match`` is ``false``, it ignores the input modifiers for :ref:`InputEventKey<class_InputEventKey>` and :ref:`InputEventMouseButton<class_InputEventMouseButton>` events, and the direction for :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>` events.

----

.. _class_InputEvent_method_is_action_type:

- :ref:`bool<class_bool>` **is_action_type** **(** **)** |const|

Returns ``true`` if this input event's type is one that can be assigned to an input action.

----

.. _class_InputEvent_method_is_echo:

- :ref:`bool<class_bool>` **is_echo** **(** **)** |const|

Returns ``true`` if this input event is an echo event (only for events of type :ref:`InputEventKey<class_InputEventKey>`).

----

.. _class_InputEvent_method_is_pressed:

- :ref:`bool<class_bool>` **is_pressed** **(** **)** |const|

Returns ``true`` if this input event is pressed. Not relevant for events of type :ref:`InputEventMouseMotion<class_InputEventMouseMotion>` or :ref:`InputEventScreenDrag<class_InputEventScreenDrag>`.

**Note:** Due to keyboard ghosting, :ref:`is_action_pressed<class_InputEvent_method_is_action_pressed>` may return ``false`` even if one of the action's keys is pressed. See `Input examples <https://docs.godotengine.org/en/3.4/tutorials/inputs/input_examples.html#keyboard-events>`__ in the documentation for more information.

----

.. _class_InputEvent_method_shortcut_match:

- :ref:`bool<class_bool>` **shortcut_match** **(** :ref:`InputEvent<class_InputEvent>` event, :ref:`bool<class_bool>` exact_match=true **)** |const|

Returns ``true`` if the specified ``event`` matches this event. Only valid for action events i.e key (:ref:`InputEventKey<class_InputEventKey>`), button (:ref:`InputEventMouseButton<class_InputEventMouseButton>` or :ref:`InputEventJoypadButton<class_InputEventJoypadButton>`), axis :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>` or action (:ref:`InputEventAction<class_InputEventAction>`) events.

If ``exact_match`` is ``false``, it ignores the input modifiers for :ref:`InputEventKey<class_InputEventKey>` and :ref:`InputEventMouseButton<class_InputEventMouseButton>` events, and the direction for :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>` events.

----

.. _class_InputEvent_method_xformed_by:

- :ref:`InputEvent<class_InputEvent>` **xformed_by** **(** :ref:`Transform2D<class_Transform2D>` xform, :ref:`Vector2<class_Vector2>` local_ofs=Vector2( 0, 0 ) **)** |const|

Returns a copy of the given input event which has been offset by ``local_ofs`` and transformed by ``xform``. Relevant for events of type :ref:`InputEventMouseButton<class_InputEventMouseButton>`, :ref:`InputEventMouseMotion<class_InputEventMouseMotion>`, :ref:`InputEventScreenTouch<class_InputEventScreenTouch>`, :ref:`InputEventScreenDrag<class_InputEventScreenDrag>`, :ref:`InputEventMagnifyGesture<class_InputEventMagnifyGesture>` and :ref:`InputEventPanGesture<class_InputEventPanGesture>`.
