<description>
[AnimatedTexture] is a resource format for frame-based animations, where multiple textures can be chained automatically with a predefined delay for each frame. Unlike [AnimationPlayer] or [AnimatedSprite2D], it isn't a [Node], but has the advantage of being usable anywhere a [Texture2D] resource can be used, e.g. in a [TileSet].
- The playback of the animation is controlled by the [member fps] property as well as each frame's optional delay (see [method set_frame_delay]). The animation loops, i.e. it will restart at frame 0 automatically after playing the last frame.
+ The playback of the animation is controlled by the [member speed_scale] property, as well as each frame's duration (see [method set_frame_duration]). The animation loops, i.e. it will restart at frame 0 automatically after playing the last frame.
[AnimatedTexture] currently requires all frame textures to have the same size, otherwise the bigger ones will be cropped to match the smallest one.
[b]Note:[/b] AnimatedTexture doesn't support using [AtlasTexture]s. Each frame needs to be a separate [Texture2D].

- Sets an additional delay (in seconds) between this frame and the next one, that will be added to the time interval defined by [member fps]. By default, frames have no delay defined. If a delay value is defined, the final time interval between this frame and the next will be [code]1.0 / fps + delay[/code].
- For example, for an animation with 3 frames, 2 FPS and a frame delay on the second frame of 1.2, the resulting playback will be:
- [codeblock]
- Frame 0: 0.5 s (1 / fps)
- Frame 1: 1.7 s (1 / fps + 1.2)
- Frame 2: 0.5 s (1 / fps)
- Total duration: 2.7 s
- [/codeblock]
+ Sets the duration of any given [param frame]. The final duration is affected by the [member speed_scale]. If set to [code]0[/code], the frame is skipped during playback.
