Ordinarily, tracks can be set to :ref:`Animation.UPDATE_DISCRETE<class_Animation_constant_UPDATE_DISCRETE>` to update infrequently, usually when using nearest interpolation.

However, when blending with :ref:`Animation.UPDATE_CONTINUOUS<class_Animation_constant_UPDATE_CONTINUOUS>` several results are considered. The :ref:`callback_mode_discrete<class_AnimationMixer_property_callback_mode_discrete>` specify it explicitly. See also :ref:`AnimationCallbackModeDiscrete<enum_AnimationMixer_AnimationCallbackModeDiscrete>`.

To make the blended results look good, it is recommended to set this to :ref:`ANIMATION_CALLBACK_MODE_DISCRETE_FORCE_CONTINUOUS<class_AnimationMixer_constant_ANIMATION_CALLBACK_MODE_DISCRETE_FORCE_CONTINUOUS>` to update every frame during blending. Other values exist for compatibility and they are fine if there is no blending, but not so, may produce artifacts.

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

- |void| **set_deterministic**\ (\ value\: :ref:`bool<class_bool>`\ )
- :ref:`bool<class_bool>` **is_deterministic**\ (\ )

If ``true``, the blending uses the deterministic algorithm. The total weight is not normalized and the result is accumulated with an initial value (``0`` or a ``"RESET"`` animation if present).

This means that if the total amount of blending is ``0.0``, the result is equal to the ``"RESET"`` animation.

If the number of tracks between the blended animations is different, the animation with the missing track is treated as if it had the initial value.

If ``false``, The blend does not use the deterministic algorithm. The total weight is normalized and always ``1.0``. If the number of tracks between the blended animations is different, nothing is done about the animation that is missing a track.

\ **Note:** In :ref:`AnimationTree<class_AnimationTree>`, the blending with :ref:`AnimationNodeAdd2<class_AnimationNodeAdd2>`, :ref:`AnimationNodeAdd3<class_AnimationNodeAdd3>`, :ref:`AnimationNodeSub2<class_AnimationNodeSub2>` or the weight greater than ``1.0`` may produce unexpected results.

For example, if :ref:`AnimationNodeAdd2<class_AnimationNodeAdd2>` blends two nodes with the amount ``1.0``, then total weight is ``2.0`` but it will be normalized to make the total amount ``1.0`` and the result will be equal to :ref:`AnimationNodeBlend2<class_AnimationNodeBlend2>` with the amount ``0.5``.

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.

The path to the Animation track used for root motion.

Adds ``library`` to the animation player, under the key ``name``.

AnimationMixer has a global library by default with an empty string as key. For adding an animation to the global library:


.. tabs::

If the animation track specified by ``name`` has an option :ref:`Animation.UPDATE_CAPTURE<class_Animation_constant_UPDATE_CAPTURE>`, stores current values of the objects indicated by the track path as a cache. If there is already a captured cache, the old cache is discarded.

After this it will interpolate with current animation blending result during the playback process for the time specified by ``duration``, working like a crossfade.

You can specify ``trans_type`` as the curve for the interpolation. For better results, it may be appropriate to specify :ref:`Tween.TRANS_LINEAR<class_Tween_constant_TRANS_LINEAR>` for cases where the first key of the track begins with a non-zero value or where the key value does not change, and :ref:`Tween.TRANS_QUAD<class_Tween_constant_TRANS_QUAD>` for cases where the key value changes linearly.

.. rst-class:: classref-method

:ref:`Vector3<class_Vector3>` **get_root_motion_position**\ (\ ) |const| :ref:`🔗<class_AnimationMixer_method_get_root_motion_position>`

Retrieve the motion delta of position with the :ref:`root_motion_track<class_AnimationMixer_property_root_motion_track>` as a :ref:`Vector3<class_Vector3>` that can be used elsewhere.

If :ref:`root_motion_track<class_AnimationMixer_property_root_motion_track>` is not a path to a track of type :ref:`Animation.TYPE_POSITION_3D<class_Animation_constant_TYPE_POSITION_3D>`, returns ``Vector3(0, 0, 0)``.

See also :ref:`root_motion_track<class_AnimationMixer_property_root_motion_track>` and :ref:`RootMotionView<class_RootMotionView>`.

The most basic example is applying position to :ref:`CharacterBody3D<class_CharacterBody3D>`:


.. tabs::

 .. code-tab:: gdscript

    var current_rotation: Quaternion
    
    func _process(delta):
        if Input.is_action_just_pressed("animate"):
            current_rotation = get_quaternion()
            state_machine.travel("Animate")
        var velocity: Vector3 = current_rotation * animation_tree.get_root_motion_position() / delta
        set_velocity(velocity)
        move_and_slide()



By using this in combination with :ref:`get_root_motion_rotation_accumulator<class_AnimationMixer_method_get_root_motion_rotation_accumulator>`, you can apply the root motion position more correctly to account for the rotation of the node.


.. tabs::

 .. code-tab:: gdscript

    func _process(delta):
        if Input.is_action_just_pressed("animate"):

:ref:`Vector3<class_Vector3>` **get_root_motion_position_accumulator**\ (\ ) |const| :ref:`🔗<class_AnimationMixer_method_get_root_motion_position_accumulator>`

Retrieve the blended value of the position tracks with the :ref:`root_motion_track<class_AnimationMixer_property_root_motion_track>` as a :ref:`Vector3<class_Vector3>` that can be used elsewhere.

This is useful in cases where you want to respect the initial key values of the animation.

For example, if an animation with only one key ``Vector3(0, 0, 0)`` is played in the previous frame and then an animation with only one key ``Vector3(1, 0, 1)`` is played in the next frame, the difference can be calculated as follows:


.. tabs::

 .. code-tab:: gdscript

    var prev_root_motion_position_accumulator: Vector3
    
    func _process(delta):
        if Input.is_action_just_pressed("animate"):
            state_machine.travel("Animate")
        var current_root_motion_position_accumulator: Vector3 = animation_tree.get_root_motion_position_accumulator()
        var difference: Vector3 = current_root_motion_position_accumulator - prev_root_motion_position_accumulator
        prev_root_motion_position_accumulator = current_root_motion_position_accumulator
        transform.origin += difference



However, if the animation loops, an unintended discrete change may occur, so this is only useful for some simple use cases.

:ref:`Quaternion<class_Quaternion>` **get_root_motion_rotation_accumulator**\ (\ ) |const| :ref:`🔗<class_AnimationMixer_method_get_root_motion_rotation_accumulator>`

Retrieve the blended value of the rotation tracks with the :ref:`root_motion_track<class_AnimationMixer_property_root_motion_track>` as a :ref:`Quaternion<class_Quaternion>` that can be used elsewhere.

This is necessary to apply the root motion position correctly, taking rotation into account. See also :ref:`get_root_motion_position<class_AnimationMixer_method_get_root_motion_position>`.

Also, this is useful in cases where you want to respect the initial key values of the animation.

For example, if an animation with only one key ``Quaternion(0, 0, 0, 1)`` is played in the previous frame and then an animation with only one key ``Quaternion(0, 0.707, 0, 0.707)`` is played in the next frame, the difference can be calculated as follows:


.. tabs::

 .. code-tab:: gdscript

    var prev_root_motion_rotation_accumulator: Quaternion
    
    func _process(delta):
        if Input.is_action_just_pressed("animate"):
            state_machine.travel("Animate")
        var current_root_motion_rotation_accumulator: Quaternion = animation_tree.get_root_motion_rotation_accumulator()
        var difference: Quaternion = prev_root_motion_rotation_accumulator.inverse() * current_root_motion_rotation_accumulator
        prev_root_motion_rotation_accumulator = current_root_motion_rotation_accumulator
        transform.basis *=  Basis(difference)



However, if the animation loops, an unintended discrete change may occur, so this is only useful for some simple use cases.

.. rst-class:: classref-method

:ref:`Vector3<class_Vector3>` **get_root_motion_scale**\ (\ ) |const| :ref:`🔗<class_AnimationMixer_method_get_root_motion_scale>`

Retrieve the motion delta of scale with the :ref:`root_motion_track<class_AnimationMixer_property_root_motion_track>` as a :ref:`Vector3<class_Vector3>` that can be used elsewhere.

If :ref:`root_motion_track<class_AnimationMixer_property_root_motion_track>` is not a path to a track of type :ref:`Animation.TYPE_SCALE_3D<class_Animation_constant_TYPE_SCALE_3D>`, returns ``Vector3(0, 0, 0)``.

See also :ref:`root_motion_track<class_AnimationMixer_property_root_motion_track>` and :ref:`RootMotionView<class_RootMotionView>`.

The most basic example is applying scale to :ref:`CharacterBody3D<class_CharacterBody3D>`:


.. tabs::

 .. code-tab:: gdscript

    var current_scale: Vector3 = Vector3(1, 1, 1)
    var scale_accum: Vector3 = Vector3(1, 1, 1)
    
    func _process(delta):
        if Input.is_action_just_pressed("animate"):
            current_scale = get_scale()
            scale_accum = Vector3(1, 1, 1)
            state_machine.travel("Animate")
        scale_accum += animation_tree.get_root_motion_scale()
        set_scale(current_scale * scale_accum)

:ref:`Vector3<class_Vector3>` **get_root_motion_scale_accumulator**\ (\ ) |const| :ref:`🔗<class_AnimationMixer_method_get_root_motion_scale_accumulator>`

Retrieve the blended value of the scale tracks with the :ref:`root_motion_track<class_AnimationMixer_property_root_motion_track>` as a :ref:`Vector3<class_Vector3>` that can be used elsewhere.

For example, if an animation with only one key ``Vector3(1, 1, 1)`` is played in the previous frame and then an animation with only one key ``Vector3(2, 2, 2)`` is played in the next frame, the difference can be calculated as follows:
