Zgrid: a lightweight zig library for 2D overlap queries / broad-phase collision detection

PROJECT NAME: Zgrid Zgrid is a lightweight library for fast spatial queries in 2D scenes. I started working on it when dipping my toe into basic game development and wondering how best to handle collision detection. I wanted a data structure that was a bit more flexible than a uniform grid, and a bit more performance aware than the pointer-centric quad-trees I’d been introduced to at uni. I think I sort of achieved that in the end (2 years later! - though for most of the time the project lay fo...
