A simple godot addon that adds a new ParallaxNode node that works as an alternative to the usage of ParallaxLayer and ParallaxBackground.
This addon is no longer needed as of Godot 4.3's addition of Parallax2D, the addon will be left up for users who do not update to 4.3 or later, even if that is what I would recommend once it becomes stable.
For more information check out the Godot 4.3 dev 5 blog post as well as the original pull request.
