TL;DR
Curveball, a new open-source tool written in Rust, enables users to generate complex, customizable curves for Neverball levels. It is available on GitHub for both web and desktop platforms, offering advanced shape creation capabilities.
The developer of the open-source game Neverball has released Curveball, a new curve generation tool written in Rust, available on GitHub for web and desktop use. The tool allows level designers to create complex, custom curves beyond the circular arcs previously possible, enhancing the game’s level design flexibility.
Curveball was developed to fill a gap in Neverball’s level creation process, where existing tools like curve.c only generated simple circular arcs. The new tool leverages Rust’s capabilities and advanced algorithms such as convex hulls and Frenet frames to produce a wide variety of curves, including intricate shapes that were previously difficult or impossible to generate.
The tool works by defining 2D profiles that are extruded along paths, with options for orienting the profiles through torsion-aware rotation techniques. It offers a visual interface, accessible via web and as a downloadable desktop application, with source code openly available on GitHub. The developer emphasizes that compiling the tool is straightforward for users familiar with Rust, making it accessible for hobbyists and experienced level designers alike.
Implications for Neverball Level Design Creativity
By providing a flexible, open-source curve generator, Curveball significantly broadens the creative possibilities for Neverball level designers. It enables the creation of more complex, varied geometries, which can lead to more engaging and diverse gameplay experiences. The tool’s availability as open-source software also encourages community collaboration and further development, potentially influencing other open-source game projects that utilize similar level design techniques.

Previous Tools and the Need for Advanced Curves
Prior to Curveball, level designers relied on basic tools like curve.c, which could only generate circular arcs. While functional, these tools limited the complexity of shapes that could be incorporated into levels. The development of Curveball was motivated by the desire to produce more intricate shapes, which are essential for creating more dynamic and visually interesting levels in Neverball. The use of Rust and algorithms like convex hulls and Frenet frames represents a significant technical advancement in this domain.
“Curveball is designed to fill the gaps in existing curve generation tools, offering a visualizer and a wide array of shape options.”
