Animation
=========
**Inherits:** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
Contains data used to animate everything in the engine.
Description
-----------
An Animation resource contains data used to animate everything in the engine. Animations are divided into tracks, and each track must be linked to a node. The state of that node can be changed through time, by adding timed keys (events) to the track.
.. tabs::
.. code-tab:: gdscript
# This creates an animation that makes the node "Enemy" move to the right by
# 100 pixels in 0.5 seconds.
var animation = Animation.new()
var track_index = animation.add_track(Animation.TYPE_VALUE)
animation.track_set_path(track_index, "Enemy:position:x")
animation.track_insert_key(track_index, 0.0, 0)
animation.track_insert_key(track_index, 0.5, 100)
.. code-tab:: csharp
// This creates an animation that makes the node "Enemy" move to the right by
// 100 pixels in 0.5 seconds.
var animation = new Animation();
int trackIndex = animation.AddTrack(Animation.TrackType.Value);
animation.TrackSetPath(trackIndex, "Enemy:position:x");
animation.TrackInsertKey(trackIndex, 0.0f, 0);
animation.TrackInsertKey(trackIndex, 0.5f, 100);
Animations are just data containers, and must be added to nodes such as an :ref:`AnimationPlayer<class_AnimationPlayer>` to be played back. Animation tracks have different types, each with its own set of dedicated methods. Check :ref:`TrackType<enum_Animation_TrackType>` to see available types.

Signals

.. _class_Animation_signal_tracks_changed:
- **tracks_changed** **(** **)**
Emitted when there's a change in the list of tracks, e.g. tracks are added, moved or have changed paths.

- **TYPE_BLEND_SHAPE** = **4**
- **TYPE_METHOD** = **5** --- Method tracks call functions with given arguments per key.
- **TYPE_BEZIER** = **6** --- Bezier tracks are used to interpolate a value using custom curves. They can also be used to animate sub-properties of vectors and colors (e.g. alpha value of a :ref:`Color<class_Color>`).
- **TYPE_AUDIO** = **7** --- Audio tracks are used to play an audio stream with either type of :ref:`AudioStreamPlayer<class_AudioStreamPlayer>`. The stream can be trimmed and previewed in the animation.
- **TYPE_ANIMATION** = **8** --- Animation tracks play animations in other :ref:`AnimationPlayer<class_AnimationPlayer>` nodes.
