InputEventAction
================

**Inherits:** :ref:`InputEvent<class_InputEvent>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

An input event type for actions.

.. rst-class:: classref-introduction-group

Description
-----------

Contains a generic action which can be targeted from several types of inputs. Actions and their events can be set in the **Input Map** tab in **Project > Project Settings**, or with the :ref:`InputMap<class_InputMap>` class.

\ **Note:** Unlike the other :ref:`InputEvent<class_InputEvent>` subclasses which map to unique physical events, this virtual one is not emitted by the engine. This class is useful to emit actions manually with :ref:`Input.parse_input_event<class_Input_method_parse_input_event>`, which are then received in :ref:`Node._input<class_Node_method__input>`. To check if a physical event matches an action from the Input Map, use :ref:`InputEvent.is_action<class_InputEvent_method_is_action>` and :ref:`InputEvent.is_action_pressed<class_InputEvent_method_is_action_pressed>`.

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

.. _class_InputEventAction_property_action:

.. rst-class:: classref-property

:ref:`StringName<class_StringName>` **action** = ``&""``

.. rst-class:: classref-property-setget

- void **set_action** **(** :ref:`StringName<class_StringName>` value **)**
- :ref:`StringName<class_StringName>` **get_action** **(** **)**

The action's name. Actions are accessed via this :ref:`String<class_String>`.

.. rst-class:: classref-item-separator

----

.. _class_InputEventAction_property_pressed:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **pressed** = ``false``

.. rst-class:: classref-property-setget

- void **set_pressed** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_pressed** **(** **)**

If ``true``, the action's state is pressed. If ``false``, the action's state is released.

.. rst-class:: classref-item-separator

----

.. _class_InputEventAction_property_strength:

.. rst-class:: classref-property

:ref:`float<class_float>` **strength** = ``1.0``

.. rst-class:: classref-property-setget

- void **set_strength** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_strength** **(** **)**

The action's strength between 0 and 1. This value is considered as equal to 0 if pressed is ``false``. The event strength allows faking analog joypad motion events, by specifying how strongly the joypad axis is bent or pressed.
