cuberact-library

A growing collection of GDExtension components for Godot 4.5+

Starting with CRope2D — a 2D rope physics node built on Verlet integration. Collisions, anchoring, breaking, and a fully modular architecture for forces, rendering, and line processing.

Features

• Verlet integration with configurable stiffness & damping
• Collision support (StaticBody2D, RigidBody2D, CharacterBody2D)
• Anchor system with two-way physical interaction
• Modular architecture — forces, line processing, breaking, rendering
• Write custom modules in GDScript — no C++ required
• Debug probe for performance profiling

Built-in Modules

• Force: Gravity, Wind, Magnet
• Line: Smooth, Simplify, Subdivide
• Render: Direct, Line2D, Debug
• Break: Tension-based

14 Example Scenes

Every feature comes with an interactive example. Stiffness, gravity, magnets, collisions, grappling hooks, stress tests, and more. Download the project, open in Godot, and explore everything hands-on.

Getting Started

Just grab it and start playing:

• Godot Asset Library — search for "cuberact" right inside the Godot Editor and install with one click
• GitHub — clone or download from the repository
• itch.io — download from this page

The download includes the full library, 14 example scenes, and 10 custom module examples.
