Threen - Godot 3 Tween for Godot 4

Threen is a forward port of Godot 3's Tween node to Godot 4, provided as a GDExtension library.

Why?

Godot 4 already has a different and better Tween class, which corresponds to what was backported to Godot 3.5+ as SceneTreeTween.

But some users have complex Godot 3 projects using the old Tween API extensively, and would benefit from keeping access to it when porting their projects to Godot 4.

Therefore Threen is provided as a 1:1 forward port Godot 3's Tween. You only need to add the GDExtension to your project ported from Godot 3, and replace uses of the Tween node in your scenes and scripts with Threen. The rest of the API stays unchanged, i.e. it's still tween_completed, etc.

How to use

• Compile the library with scons.
• Copy the bin folder to the demo folder to try it out with the premade project.
