Spline Grind (with demo)

The game!

In the Computer Graphics 2 course at TUB, we discussed B-splines. To become more familiar with the concept (and because I had a fun game idea), I decided to experiment with a game mechanic using B-splines.

Instead of directly controlling the player, the mouse influences the world around them. Over time, you develop a sense of how to use this mechanic to make the player move and jump. I think this could make for a really fun platformer.

How it works

I used Bevy Game Engine to create this—mostly because I wanted to learn Rust, but also because it offers a lot of freedom.

The line is composed of many control points that move when the mouse gets near. The line is then constructed using the B-spline algorithm (de Boor’s algorithm). Collisions between the ball and the line are calculated and handled in a custom physics engine.\

There are still some issues—for example, the ball can sometimes glitch through the ground. There are neat tricks that could solve this problem, but honestly, I lost interest after the course ended.

I’m still leaving the demo here for your enjoyment. Maybe I’ll continue working on it someday.
