Proxy texture for simple frame-based animations.
[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 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].
[b]Warning:[/b] The current implementation is not efficient for the modern renderers.
Returns the given [param frame]'s duration, in seconds.
Returns the given frame's [Texture2D].
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.
Assigns a [Texture2D] to the given frame. Frame IDs start at 0, so the first frame has ID 0, and the last frame of the animation has ID [member frames] - 1.
You can define any number of textures up to [constant MAX_FRAMES], but keep in mind that only frames from 0 to [member frames] - 1 will be part of the animation.
Sets the currently visible frame of the texture. Setting this frame while playing resets the current frame time, so the newly selected frame plays for its whole configured frame duration.
Number of frames to use in the animation. While you can create the frames independently with [method set_frame_texture], you need to set this value for the animation to take new frames into account. The maximum number of frames is [constant MAX_FRAMES].
If [code]true[/code], the animation will only play once and will not loop back to the first frame after reaching the end. Note that reaching the end will not set [member pause] to [code]true[/code].
If [code]true[/code], the animation will pause where it currently is (i.e. at [member current_frame]). The animation will continue from where it was paused when changing this property to [code]false[/code].
The animation speed is multiplied by this value. If set to a negative value, the animation is played in reverse.
The maximum number of frames supported by [AnimatedTexture]. If you need more frames in your animation, use [AnimationPlayer] or [AnimatedSprite2D].
