Contains data used to animate everything in the engine. 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.

Animation tracks have different types, each with its own set of dedicated methods.

Inserts a Bezier Track key at the given [param time] in seconds. The [param track_idx] must be the index of a Bezier Track. [param in_handle] is the left-side weight of the added Bezier curve point, [param out_handle] is the right-side one, while [param value] is the actual value at this point. Returns the interpolated value at the given [param time] (in seconds). The [param track_idx] must be the index of a Bezier Track. Changes the handle mode of the keyframe at the given [param key_idx]. See [enum HandleMode] for possible values. The [param track_idx] must be the index of a Bezier Track. Sets the in handle of the key identified by [param key_idx] to value [param in_handle].

The [param track_idx] must be the index of a Bezier Track. Sets the value of the key identified by [param key_idx] to the given value. The [param track_idx] must be the index of a Bezier Track. Clear the animation (clear all tracks and reset all). Adds a new track that is a copy of the given track from [param to_animation]. Returns the index of the specified track. If the track is not found, return -1. Returns the amount of tracks in the animation. Returns all the key indices of a method track, given a position and delta time. Returns the method name of a method track. Returns the arguments values to be called on a method track for a given key in a given track. Removes a track by specifying the track index. Finds the key index by time in a given track. Optionally, only find it if the exact time is given. Returns [code]true[/code] if the track at [param track_idx] wraps the interpolation loop. New tracks wrap the interpolation loop by default. Returns the interpolation type of a given track. Returns the number of keys in a given track. Returns the time at which the key is located. Returns the transition curve (easing) for a specific key (see the built-in math function [method @GlobalScope.ease]). Returns the value of a given key in a given track. Gets the path of a track. For more information on the path format, see [method track_set_path]. Gets the type of a track. Inserts a generic key in a given track. Returns the key index. Returns [code]true[/code] if the track at index [param track_idx] is enabled. Returns [code]true[/code] if the given track is imported. Else, return [code]false[/code]. Moves a track down. Changes the index position of track [param track_idx] to the one defined in [param to_idx]. Moves a track up. Removes a key by index in a given track. Removes a key at [param time] in a given track. Enables/disables the given track. Tracks are enabled by default. Sets the given track as imported or not. If [code]true[/code], the track at [param track_idx] wraps the interpolation loop. Sets the interpolation type of a given track. Sets the time of an existing key. Sets the transition curve (easing) for a specific key (see the built-in math function [method @GlobalScope.ease]). Sets the value of an existing key. Sets the path of a track. Paths must be valid scene-tree paths to a node and must be specified starting from the parent node of the node that will reproduce the animation. Tracks that control properties or bones must append their name after the path, separated by [code]":"[/code]. For example, [code]"character/skeleton:ankle"[/code] or [code]"character/mesh:transform/local"[/code]. Swaps the track [param track_idx]'s index position with the track [param with_idx]. Returns all the key indices of a value track, given a position and delta time. Returns the update mode of a value track. Returns the interpolated value at the given time (in seconds). The [param track_idx] must be the index of a value track. Sets the update mode (see [enum UpdateMode]) of a value track. The total length of the animation (in seconds). [b]Note:[/b] Length is not delimited by the last key, as this one may be before or after the end to ensure correct interpolation and looping. Determines the behavior of both ends of the animation timeline during animation playback. This is used for correct interpolation of animation cycles, and for hinting the player that it must restart the animation. The animation step value. Emitted when there's a change in the list of tracks, e.g. tracks are added, moved or have changed paths. Value tracks set values in node properties, but only those which can be Interpolated. Method tracks call functions with given arguments per key. 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 [Color]). Audio tracks are used to play an audio stream with either type of [AudioStreamPlayer]. The stream can be trimmed and previewed in the animation. Animation tracks play animations in other [AnimationPlayer] nodes. No interpolation (nearest value). Linear interpolation. Cubic interpolation. Update between keyframes. Update at the keyframes and hold the value. Update at the keyframes. Same as linear interpolation, but also interpolates from the current value (i.e. dynamically at runtime) if the first key isn't at 0 seconds. At both ends of the animation, the animation will stop playing. At both ends of the animation, the animation will be repeated without changing the playback direction. Repeats playback and reverse playback at both ends of the animation. Assigning the free handle mode to a Bezier Track's keyframe allows you to edit the keyframe's left and right handles independently from one another. Assigning the balanced handle mode to a Bezier Track's keyframe makes it so the two handles of the keyframe always stay aligned when changing either the keyframe's left or right handle.
