:ref:`bool<class_bool>` **accumulate**\ (\ with_event\: :ref:`InputEvent<class_InputEvent>`\ ) :ref:`🔗<class_InputEvent_method_accumulate>`
|
|
|
|
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.

|
|
|
|
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 additional input modifiers for :ref:`InputEventKey<class_InputEventKey>` and :ref:`InputEventMouseButton<class_InputEventMouseButton>` events, and the direction for :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>` events.

|
|
|
|
Returns ``true`` if this input event matches a pre-defined action of any type.
|
|
|
|
If ``exact_match`` is ``false``, it ignores additional input modifiers for :ref:`InputEventKey<class_InputEventKey>` and :ref:`InputEventMouseButton<class_InputEventMouseButton>` events, and the direction for :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>` events.

|
|
|
|
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 additional 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 <../tutorials/inputs/input_examples.html#keyboard-events>`__ in the documentation for more information.

|
|
|

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 additional input modifiers for :ref:`InputEventKey<class_InputEventKey>` and :ref:`InputEventMouseButton<class_InputEventMouseButton>` events, and the direction for :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>` events.

|
|
|
|
:ref:`bool<class_bool>` **is_echo**\ (\ ) |const| :ref:`🔗<class_InputEvent_method_is_echo>`
|
|
|
|
Returns ``true`` if this input event is an echo event (only for events of type :ref:`InputEventKey<class_InputEventKey>`). An echo event is a repeated key event sent when the user is holding down the key. Any other event type returns ``false``.
|
|
|
|
\ **Note:** The rate at which echo events are sent is typically around 20 events per second (after holding down the key for roughly half a second). However, the key repeat delay/speed can be changed by the user or disabled entirely in the operating system settings. To ensure your project works correctly on all configurations, do not assume the user has a specific key repeat configuration in your project's behavior.

|
|
|
|
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 additional input modifiers for :ref:`InputEventKey<class_InputEventKey>` and :ref:`InputEventMouseButton<class_InputEventMouseButton>` events, and the direction for :ref:`InputEventJoypadMotion<class_InputEventJoypadMotion>` events.
|
|
|

\ **Note:** Only considers the event configuration (such as the keyboard key or joypad axis), not state information like :ref:`is_pressed<class_InputEvent_method_is_pressed>`, :ref:`is_released<class_InputEvent_method_is_released>`, :ref:`is_echo<class_InputEvent_method_is_echo>`, or :ref:`is_canceled<class_InputEvent_method_is_canceled>`.
