This is an addon for the Godot Game Engine. It should work with all versions >= 4.0, but it is a work in progress and not ready for production.
The addon provides the InteractiveCurve2D node. Once you've copied the addon to your project, you should find a new InteractiveCurve2D node in the editor's node creation dialog.
The InteractiveCurve2D node lets you display Curve2D objects and interactively manipulate these objects inside your running application. It's main purpose is the interactive handling of Bézier curves.
Note: It is not a tool meant for use directly in the Godot Editor. The Godot Editor already has a UI for manipulating curves where necessary.
The addon includes a demonstration scene. You can find it under
addons/InteractiveShapes2D/demo.tscn.
Make sure to read the comments on the current limitations of the signals provided
in demo.gd before you file bug reports concerning these.
