Signals
-------

.. _class_AnimationLibrary_signal_animation_added:

.. rst-class:: classref-signal

**animation_added** **(** :ref:`StringName<class_StringName>` name **)**

Emitted when an :ref:`Animation<class_Animation>` is added, under the key ``name``.

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

----

.. _class_AnimationLibrary_signal_animation_changed:

.. rst-class:: classref-signal

**animation_changed** **(** :ref:`StringName<class_StringName>` name **)**

Emitted when there's a change in one of the animations, e.g. tracks are added, moved or have changed paths. ``name`` is the key of the animation that was changed.

See also :ref:`Resource.changed<class_Resource_signal_changed>`, which this acts as a relay for.

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

----

.. _class_AnimationLibrary_signal_animation_removed:

.. rst-class:: classref-signal

**animation_removed** **(** :ref:`StringName<class_StringName>` name **)**

Emitted when an :ref:`Animation<class_Animation>` stored with the key ``name`` is removed.

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

----

.. _class_AnimationLibrary_signal_animation_renamed:

.. rst-class:: classref-signal

**animation_renamed** **(** :ref:`StringName<class_StringName>` name, :ref:`StringName<class_StringName>` to_name **)**

Emitted when the key for an :ref:`Animation<class_Animation>` is changed, from ``name`` to ``to_name``.

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

.. _class_AnimationLibrary_method_add_animation:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **add_animation** **(** :ref:`StringName<class_StringName>` name, :ref:`Animation<class_Animation>` animation **)**

Adds the ``animation`` to the library, accessible by the key ``name``.

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

----

.. _class_AnimationLibrary_method_get_animation:

.. rst-class:: classref-method

:ref:`Animation<class_Animation>` **get_animation** **(** :ref:`StringName<class_StringName>` name **)** |const|

Returns the :ref:`Animation<class_Animation>` with the key ``name``. If the animation does not exist, ``null`` is returned and an error is logged.

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

----

.. _class_AnimationLibrary_method_get_animation_list:

.. rst-class:: classref-method

:ref:`StringName[]<class_StringName>` **get_animation_list** **(** **)** |const|

Returns the keys for the :ref:`Animation<class_Animation>`\ s stored in the library.

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

----

.. _class_AnimationLibrary_method_has_animation:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **has_animation** **(** :ref:`StringName<class_StringName>` name **)** |const|

Returns ``true`` if the library stores an :ref:`Animation<class_Animation>` with ``name`` as the key.

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

----

.. _class_AnimationLibrary_method_remove_animation:

.. rst-class:: classref-method

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

Removes the :ref:`Animation<class_Animation>` with the key ``name``.

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

----

.. _class_AnimationLibrary_method_rename_animation:

.. rst-class:: classref-method

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

Changes the key of the :ref:`Animation<class_Animation>` associated with the key ``name`` to ``newname``.
