An animation player is used for general-purpose playback of animations. It contains a dictionary of [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 [code]"movement/run"[/code]. 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 [Tween] for more complex animations, for example ones with non-trivial timings. It can also be used over [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.
Returns the actual playing speed of current animation or [code]0[/code] if not playing. This speed is the [member speed_scale] property multiplied by [code]custom_speed[/code] argument specified when calling the [method play] method.
Returns a negative value if the current animation is playing backwards.
Pauses the currently playing animation. The [member current_animation_position] will be kept and calling [method play] or [method play_backwards] without arguments or with the same animation name as [member assigned_animation] will resume the animation.
Plays the animation with key [param name]. Custom blend times and speed can be set.
The [param 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 [param custom_speed] is negative and [param from_end] is [code]true[/code], the animation will play backwards (which is equivalent to calling [method play_backwards]).
The [AnimationPlayer] keeps track of its current or last played animation with [member assigned_animation]. If this method is called with that same animation [param name], or with no [param name] parameter, the assigned animation will resume playing if it was paused.
[b]Note:[/b] 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 [code]advance(0)[/code].
This method is a shorthand for [method play] with [code]custom_speed = -1.0[/code] and [code]from_end = true[/code], so see its description for more information.
See [method AnimationMixer.capture]. It is almost the same as the following:
[codeblock]
capture(name, duration, trans_type, ease_type)
play(name, custom_blend, custom_speed, from_end)
[/codeblock]
If name is blank, it specifies [member assigned_animation].
If [param duration] is a negative value, the duration is set to the interval between the current position and the first key, when [param from_end] is [code]true[/code], uses the interval between the current position and the last key instead.
[b]Note:[/b] The [param duration] takes [member speed_scale] into account, but [param custom_speed] does not, because the capture cache is interpolated with the blend result and the result may contain multiple animations.
Seeks the animation to the [param seconds] point in time (in seconds). If [param update] is [code]true[/code], the animation updates too, otherwise it updates at process time. Events between the current frame and [param seconds] are skipped.
[b]Note:[/b] Seeking to the end of the animation doesn't emit [signal AnimationMixer.animation_finished]. If you want to skip animation and emit the signal, use [method AnimationMixer.advance].
Stops the currently playing animation. The animation position is reset to [code]0[/code] and the [code]custom_speed[/code] is reset to [code]1.0[/code]. See also [method pause].
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 [member 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 [method play] for more information on playing animations.
[b]Note:[/b] 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 [Animation].
If [code]true[/code] and the engine is running in Movie Maker mode (see [MovieWriter]), exits the engine with [method SceneTree.quit] as soon as an animation is done playing in this [AnimationPlayer]. A message is printed when the engine quits for this reason.
[b]Note:[/b] This obeys the same logic as the [signal AnimationMixer.animation_finished] signal, so it will not quit the engine if the animation is set to be looping.
The speed scaling ratio. For example, if this value is [code]1[/code], then the animation plays at normal speed. If it's [code]0.5[/code], then it plays at half speed. If it's [code]2[/code], then it plays at double speed.
If set to a negative value, the animation is played in reverse. If set to [code]0[/code], the animation will not advance.
