AnimationPlayer
===============

**Inherits:** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

A node used for animation playback.

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

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

An animation player is used for general-purpose playback of animations. It contains a dictionary of :ref:`AnimationLibrary<class_AnimationLibrary>` resources and custom blend times between animation transitions.

Some methods and properties use a single key to reference an animation directly. These keys are formatted as the key for the library, followed by a forward slash, then the key for the animation within the library, for example ``"movement/run"``. If the library's key is an empty string (known as the default library), the forward slash is omitted, being the same key used by the library.

\ **AnimationPlayer** is better-suited than :ref:`Tween<class_Tween>` for more complex animations, for example ones with non-trivial timings. It can also be used over :ref:`Tween<class_Tween>` if the animation track editor is more convenient than doing it in code.

Updating the target properties of animations occurs at the process frame.

.. rst-class:: classref-property

:ref:`String<class_String>` **assigned_animation**

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

- void **set_assigned_animation** **(** :ref:`String<class_String>` value **)**
- :ref:`String<class_String>` **get_assigned_animation** **(** **)**

If playing, the current animation's key, otherwise, the animation last played. When set, this changes the animation, but will not play it unless already playing. See also :ref:`current_animation<class_AnimationPlayer_property_current_animation>`.

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

----

.. _class_AnimationPlayer_property_audio_max_polyphony:

.. rst-class:: classref-property

:ref:`int<class_int>` **audio_max_polyphony** = ``32``

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

- void **set_audio_max_polyphony** **(** :ref:`int<class_int>` value **)**
- :ref:`int<class_int>` **get_audio_max_polyphony** **(** **)**

The number of possible simultaneous sounds for each of the assigned AudioStreamPlayers.

For example, if this value is ``32`` and the animation has two audio tracks, the two :ref:`AudioStreamPlayer<class_AudioStreamPlayer>`\ s assigned can play simultaneously up to ``32`` voices each.

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

----

.. _class_AnimationPlayer_property_autoplay:

.. rst-class:: classref-property

:ref:`String<class_String>` **autoplay** = ``""``

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

- void **set_autoplay** **(** :ref:`String<class_String>` value **)**
- :ref:`String<class_String>` **get_autoplay** **(** **)**

- void **set_current_animation** **(** :ref:`String<class_String>` value **)**
- :ref:`String<class_String>` **get_current_animation** **(** **)**

The key of the currently playing animation. If no animation is playing, the property's value is an empty string. Changing this value does not restart the animation. See :ref:`play<class_AnimationPlayer_method_play>` for more information on playing animations.

\ **Note:** While this property appears in the Inspector, it's not meant to be edited, and it's not saved in the scene. This property is mainly used to get the currently playing animation, and internally for animation playback tracks. For more information, see :ref:`Animation<class_Animation>`.

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

----

.. _class_AnimationPlayer_property_current_animation_length:

.. rst-class:: classref-property

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

- void **set_method_call_mode** **(** :ref:`AnimationMethodCallMode<enum_AnimationPlayer_AnimationMethodCallMode>` value **)**
- :ref:`AnimationMethodCallMode<enum_AnimationPlayer_AnimationMethodCallMode>` **get_method_call_mode** **(** **)**

The call mode to use for Call Method tracks.

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

----

.. _class_AnimationPlayer_property_movie_quit_on_finish:

.. rst-class:: classref-property

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

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

- void **set_movie_quit_on_finish_enabled** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_movie_quit_on_finish_enabled** **(** **)**

If ``true`` and the engine is running in Movie Maker mode (see :ref:`MovieWriter<class_MovieWriter>`), exits the engine with :ref:`SceneTree.quit<class_SceneTree_method_quit>` as soon as an animation is done playing in this **AnimationPlayer**. A message is printed when the engine quits for this reason.

\ **Note:** This obeys the same logic as the :ref:`animation_finished<class_AnimationPlayer_signal_animation_finished>` signal, so it will not quit the engine if the animation is set to be looping.

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

----

.. _class_AnimationPlayer_property_playback_active:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **playback_active**

- void **set_active** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_active** **(** **)**

If ``true``, updates animations in response to process-related notifications.

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

----

.. _class_AnimationPlayer_property_playback_default_blend_time:

.. rst-class:: classref-property

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

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

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

- :ref:`AnimationProcessCallback<enum_AnimationPlayer_AnimationProcessCallback>` **get_process_callback** **(** **)**

The process notification in which to update animations.

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

----

.. _class_AnimationPlayer_property_reset_on_save:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **reset_on_save** = ``true``

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

- void **set_reset_on_save_enabled** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_reset_on_save_enabled** **(** **)**

This is used by the editor. If set to ``true``, the scene will be saved with the effects of the reset animation (the animation with the key ``"RESET"``) applied as if it had been seeked to time 0, with the editor keeping the values that the scene had before saving.

This makes it more convenient to preview and edit animations in the editor, as changes to the scene will not be saved as long as they are set in the reset animation.

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

----

.. _class_AnimationPlayer_property_root_node:

.. rst-class:: classref-property

:ref:`NodePath<class_NodePath>` **root_node** = ``NodePath("..")``

- :ref:`NodePath<class_NodePath>` **get_root** **(** **)**

The node from which node path references will travel.

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

----

.. _class_AnimationPlayer_property_speed_scale:

.. rst-class:: classref-property

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

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

- void **set_speed_scale** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_speed_scale** **(** **)**

The speed scaling ratio. For example, if this value is ``1``, then the animation plays at normal speed. If it's ``0.5``, then it plays at half speed. If it's ``2``, then it plays at double speed.

If set to a negative value, the animation is played in reverse. If set to ``0``, the animation will not advance.

void **play** **(** :ref:`StringName<class_StringName>` name="", :ref:`float<class_float>` custom_blend=-1, :ref:`float<class_float>` custom_speed=1.0, :ref:`bool<class_bool>` from_end=false **)**

Plays the animation with key ``name``. Custom blend times and speed can be set.

The ``from_end`` option only affects when switching to a new animation track, or if the same track but at the start or end. It does not affect resuming playback that was paused in the middle of an animation. If ``custom_speed`` is negative and ``from_end`` is ``true``, the animation will play backwards (which is equivalent to calling :ref:`play_backwards<class_AnimationPlayer_method_play_backwards>`).

The **AnimationPlayer** keeps track of its current or last played animation with :ref:`assigned_animation<class_AnimationPlayer_property_assigned_animation>`. If this method is called with that same animation ``name``, or with no ``name`` parameter, the assigned animation will resume playing if it was paused.

\ **Note:** The animation will be updated the next time the **AnimationPlayer** is processed. If other variables are updated at the same time this is called, they may be updated too early. To perform the update immediately, call ``advance(0)``.

.. _class_AnimationPlayer_method_play_backwards:

.. rst-class:: classref-method

void **play_backwards** **(** :ref:`StringName<class_StringName>` name="", :ref:`float<class_float>` custom_blend=-1 **)**

Plays the animation with key ``name`` in reverse.

This method is a shorthand for :ref:`play<class_AnimationPlayer_method_play>` with ``custom_speed = -1.0`` and ``from_end = true``, so see its description for more information.

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

.. _class_AnimationPlayer_method_queue:

.. rst-class:: classref-method

void **queue** **(** :ref:`StringName<class_StringName>` name **)**

Queues an animation for playback once the current one is done.

\ **Note:** If a looped animation is currently playing, the queued animation will never play unless the looped animation is stopped somehow.

----

.. _class_AnimationPlayer_method_remove_animation_library:

.. rst-class:: classref-method

void **remove_animation_library** **(** :ref:`StringName<class_StringName>` name **)**

Removes the :ref:`AnimationLibrary<class_AnimationLibrary>` associated with the key ``name``.

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

----

.. _class_AnimationPlayer_method_rename_animation_library:

.. rst-class:: classref-method

void **rename_animation_library** **(** :ref:`StringName<class_StringName>` name, :ref:`StringName<class_StringName>` newname **)**

Moves the :ref:`AnimationLibrary<class_AnimationLibrary>` associated with the key ``name`` to the key ``newname``.

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

----

.. _class_AnimationPlayer_method_seek:

.. rst-class:: classref-method

void **seek** **(** :ref:`float<class_float>` seconds, :ref:`bool<class_bool>` update=false **)**

Seeks the animation to the ``seconds`` point in time (in seconds). If ``update`` is ``true``, the animation updates too, otherwise it updates at process time. Events between the current frame and ``seconds`` are skipped.

\ **Note:** Seeking to the end of the animation doesn't emit :ref:`animation_finished<class_AnimationPlayer_signal_animation_finished>`. If you want to skip animation and emit the signal, use :ref:`advance<class_AnimationPlayer_method_advance>`.

.. _class_AnimationPlayer_method_set_blend_time:

.. rst-class:: classref-method

void **set_blend_time** **(** :ref:`StringName<class_StringName>` anim_from, :ref:`StringName<class_StringName>` anim_to, :ref:`float<class_float>` sec **)**

Specifies a blend time (in seconds) between two animations, referenced by their keys.

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

----

.. _class_AnimationPlayer_method_stop:

.. rst-class:: classref-method

void **stop** **(** :ref:`bool<class_bool>` keep_state=false **)**

Stops the currently playing animation. The animation position is reset to ``0`` and the ``custom_speed`` is reset to ``1.0``. See also :ref:`pause<class_AnimationPlayer_method_pause>`.

If ``keep_state`` is ``true``, the animation state is not updated visually.

\ **Note:** The method / audio / animation playback tracks will not be processed by this method.
