The first version was written in just under 1 hour. If it wasn't for a silly malloc bug for the QuadTreeQueryResult, I would have finished it in less than 50 minutes! This example was inspired by Daniel Shiffman's Coding Challenge on the same subject! Building something like this in C has some complications over JavaScript, but it was a great exercise and a topic I can cover in a few videos on the channel.
In the future I am likely to fork this repo and build a C++ version as well, (which will be much easier than what I've done here to be honest!)
Thanks to Ramon Santamaria (@raysan5) for the framework I call home. Thanks to Jeffery Myers for game-premake, which provides the clean portability between IDEs for Raylib projects. Special Thanks to Daniel Shiffman and The Coding Train.
