		Plays an animation once in an [AnimationNodeBlendTree].
	</brief_description>
	<description>
		A resource to add to an [AnimationNodeBlendTree]. This animation node will execute a sub-animation and return once it finishes. Blend times for fading in and out can be customized, as well as filters.
		After setting the request and changing the animation playback, the one-shot node automatically clears the request on the next process frame by setting its [code]request[/code] value to [constant ONE_SHOT_REQUEST_NONE].

		<member name="autorestart" type="bool" setter="set_autorestart" getter="has_autorestart" default="false">
			If [code]true[/code], the sub-animation will restart automatically after finishing.
			In other words, to start auto restarting, the animation must be played once with the [constant ONE_SHOT_REQUEST_FIRE] request. The [constant ONE_SHOT_REQUEST_ABORT] request stops the auto restarting, but it does not disable the [member autorestart] itself. So, the [constant ONE_SHOT_REQUEST_FIRE] request will start auto restarting again.
		</member>
		<member name="autorestart_delay" type="float" setter="set_autorestart_delay" getter="get_autorestart_delay" default="1.0">
			The delay after which the automatic restart is triggered, in seconds.
		</member>
		<member name="autorestart_random_delay" type="float" setter="set_autorestart_random_delay" getter="get_autorestart_random_delay" default="0.0">
			If [member autorestart] is [code]true[/code], a random additional delay (in seconds) between 0 and this value will be added to [member autorestart_delay].
		</member>
		<member name="break_loop_at_end" type="bool" setter="set_break_loop_at_end" getter="is_loop_broken_at_end" default="false">
			If [code]true[/code], breaks the loop at the end of the loop cycle for transition, even if the animation is looping.
		</member>
		<member name="fadein_curve" type="Curve" setter="set_fadein_curve" getter="get_fadein_curve">
			Determines how cross-fading between animations is eased. If empty, the transition will be linear.
		</member>
		<member name="fadein_time" type="float" setter="set_fadein_time" getter="get_fadein_time" default="0.0">
			The fade-in duration. For example, setting this to [code]1.0[/code] for a 5 second length animation will produce a cross-fade that starts at 0 second and ends at 1 second during the animation.
			[b]Note:[/b] [AnimationNodeOneShot] transitions the current state after the end of the fading. When [AnimationNodeOutput] is considered as the most upstream, so the [member fadein_time] is scaled depending on the downstream delta. For example, if this value is set to [code]1.0[/code] and a [AnimationNodeTimeScale] with a value of [code]2.0[/code] is chained downstream, the actual processing time will be 0.5 second.

		<member name="fadeout_curve" type="Curve" setter="set_fadeout_curve" getter="get_fadeout_curve">
			Determines how cross-fading between animations is eased. If empty, the transition will be linear.
		</member>
		<member name="fadeout_time" type="float" setter="set_fadeout_time" getter="get_fadeout_time" default="0.0">
			The fade-out duration. For example, setting this to [code]1.0[/code] for a 5 second length animation will produce a cross-fade that starts at 4 second and ends at 5 second during the animation.
			[b]Note:[/b] [AnimationNodeOneShot] transitions the current state after the end of the fading.
