Sprite frame library for AnimatedSprite2D and AnimatedSprite3D. Sprite frame library for an [AnimatedSprite2D] or [AnimatedSprite3D] node. Contains frames and animation data for playback. [b]Note:[/b] You can associate a set of normal or specular maps by creating additional [SpriteFrames] resources with a [code]_normal[/code] or [code]_specular[/code] suffix. For example, having 3 [SpriteFrames] resources [code]run[/code], [code]run_normal[/code], and [code]run_specular[/code] will make it so the [code]run[/code] animation uses normal and specular maps. Adds a new animation to the library. Adds a frame to the given animation. Removes all frames from the given animation. Removes all animations. A "default" animation will be created. Returns [code]true[/code] if the given animation is configured to loop when it finishes playing. Otherwise, returns [code]false[/code]. Returns an array containing the names associated to each animation. Values are placed in alphabetical order. Returns the speed in frames per second for the [param anim] animation. Returns the number of frames for the [param anim] animation. Returns a relative duration of the frame [param idx] in the [param anim] animation (defaults to [code]1.0[/code]). For example, a frame with a duration of [code]2.0[/code] is displayed twice as long as a frame with a duration of [code]1.0[/code]. You can calculate the absolute duration (in seconds) of a frame using the following formula: [codeblock] absolute_duration = relative_duration / (animation_fps * abs(speed_scale)) [/codeblock] In this example, [code]speed_scale[/code] refers to either [member AnimatedSprite2D.speed_scale] or [member AnimatedSprite3D.speed_scale]. Returns the texture of the frame [param idx] in the [param anim] animation. If [code]true[/code], the named animation exists. Removes the given animation. Removes the animation's selected frame. Changes the animation's name to [param newname]. If [code]true[/code], the animation will loop. Sets the speed for the [param anim] animation in frames per second. Sets the texture and the duration of the frame [param idx] in the [param anim] animation.
