Plays an animation once in an :ref:`AnimationNodeBlendTree<class_AnimationNodeBlendTree>`.

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

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

A resource to add to an :ref:`AnimationNodeBlendTree<class_AnimationNodeBlendTree>`. This node will execute a sub-animation and return once it finishes. Blend times for fading in and out can be customized, as well as filters.

After setting the request and changing the animation playback, the one-shot node automatically clears the request on the next process frame by setting its ``request`` value to :ref:`ONE_SHOT_REQUEST_NONE<class_AnimationNodeOneShot_constant_ONE_SHOT_REQUEST_NONE>`.

Enumerations
------------

.. _enum_AnimationNodeOneShot_OneShotRequest:

.. rst-class:: classref-enumeration

enum **OneShotRequest**:

.. _class_AnimationNodeOneShot_constant_ONE_SHOT_REQUEST_NONE:

.. rst-class:: classref-enumeration-constant

:ref:`OneShotRequest<enum_AnimationNodeOneShot_OneShotRequest>` **ONE_SHOT_REQUEST_NONE** = ``0``

The default state of the request. Nothing is done.

.. _class_AnimationNodeOneShot_constant_ONE_SHOT_REQUEST_FIRE:

.. rst-class:: classref-enumeration-constant

:ref:`OneShotRequest<enum_AnimationNodeOneShot_OneShotRequest>` **ONE_SHOT_REQUEST_FIRE** = ``1``

The request to play the animation connected to "shot" port.

.. _class_AnimationNodeOneShot_constant_ONE_SHOT_REQUEST_ABORT:

.. rst-class:: classref-enumeration-constant

:ref:`OneShotRequest<enum_AnimationNodeOneShot_OneShotRequest>` **ONE_SHOT_REQUEST_ABORT** = ``2``

The request to stop the animation connected to "shot" port.

.. _enum_AnimationNodeOneShot_MixMode:

.. rst-class:: classref-enumeration

enum **MixMode**:

.. _class_AnimationNodeOneShot_constant_MIX_MODE_BLEND:

.. rst-class:: classref-enumeration-constant

:ref:`MixMode<enum_AnimationNodeOneShot_MixMode>` **MIX_MODE_BLEND** = ``0``

Blends two animations. See also :ref:`AnimationNodeBlend2<class_AnimationNodeBlend2>`.

.. _class_AnimationNodeOneShot_constant_MIX_MODE_ADD:

.. rst-class:: classref-enumeration-constant

:ref:`MixMode<enum_AnimationNodeOneShot_MixMode>` **MIX_MODE_ADD** = ``1``

Blends two animations additively. See also :ref:`AnimationNodeAdd2<class_AnimationNodeAdd2>`.

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

.. _class_AnimationNodeOneShot_property_autorestart:

.. rst-class:: classref-property

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

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

- void **set_autorestart** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **has_autorestart** **(** **)**

If ``true``, the sub-animation will restart automatically after finishing.

In other words, to start auto restarting, the animation must be played once with the :ref:`ONE_SHOT_REQUEST_FIRE<class_AnimationNodeOneShot_constant_ONE_SHOT_REQUEST_FIRE>` request. The :ref:`ONE_SHOT_REQUEST_ABORT<class_AnimationNodeOneShot_constant_ONE_SHOT_REQUEST_ABORT>` request stops the auto restarting, but it does not disable the :ref:`autorestart<class_AnimationNodeOneShot_property_autorestart>` itself. So, the :ref:`ONE_SHOT_REQUEST_FIRE<class_AnimationNodeOneShot_constant_ONE_SHOT_REQUEST_FIRE>` request will start auto restarting again.

.. _class_AnimationNodeOneShot_property_autorestart_delay:

.. rst-class:: classref-property

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

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

- void **set_autorestart_delay** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_autorestart_delay** **(** **)**

The delay after which the automatic restart is triggered, in seconds.

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

----

.. _class_AnimationNodeOneShot_property_autorestart_random_delay:

.. rst-class:: classref-property

:ref:`float<class_float>` **autorestart_random_delay** = ``0.0``

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

- void **set_autorestart_random_delay** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_autorestart_random_delay** **(** **)**

If :ref:`autorestart<class_AnimationNodeOneShot_property_autorestart>` is ``true``, a random additional delay (in seconds) between 0 and this value will be added to :ref:`autorestart_delay<class_AnimationNodeOneShot_property_autorestart_delay>`.

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

----

.. _class_AnimationNodeOneShot_property_fadein_time:

.. rst-class:: classref-property

:ref:`float<class_float>` **fadein_time** = ``0.0``

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

- void **set_fadein_time** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_fadein_time** **(** **)**

The fade-in duration. For example, setting this to ``1.0`` for a 5 second length animation will produce a crossfade that starts at 0 second and ends at 1 second during the animation.

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

----

.. _class_AnimationNodeOneShot_property_fadeout_time:

.. rst-class:: classref-property

:ref:`float<class_float>` **fadeout_time** = ``0.0``

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

- void **set_fadeout_time** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_fadeout_time** **(** **)**

The fade-out duration. For example, setting this to ``1.0`` for a 5 second length animation will produce a crossfade that starts at 4 second and ends at 5 second during the animation.

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

.. _class_AnimationNodeOneShot_property_mix_mode:

.. rst-class:: classref-property

:ref:`MixMode<enum_AnimationNodeOneShot_MixMode>` **mix_mode** = ``0``

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

- void **set_mix_mode** **(** :ref:`MixMode<enum_AnimationNodeOneShot_MixMode>` value **)**
- :ref:`MixMode<enum_AnimationNodeOneShot_MixMode>` **get_mix_mode** **(** **)**

The blend type.
