Sprite frame library for AnimatedSprite and AnimatedSprite3D. Sprite frame library for an [AnimatedSprite] or [AnimatedSprite3D] node. Contains frames and animation data for playback. [b]Note:[/b] You can associate a set of normal maps by creating additional [SpriteFrames] resources with a [code]_normal[/code] suffix. For example, having 2 [SpriteFrames] resources [code]run[/code] and [code]run_normal[/code] will make it so the [code]run[/code] animation uses the normal map. Removes all animations. A "default" animation will be created. Returns an array containing the names associated to each animation. Values are placed in alphabetical order. Compatibility property, always equals to an empty array.
