To start off with, I wanted to post this screenshot from the latest iteration of my OpenGL engine. I finally managed to fix my collisions bugs and have been re-implementing features onto a basis on Qt 5 rather than SDL so that I can still use the GUI designer (because otherwise why even use Gambas?). I got sprites to work the other day. I need to finish defining my map format before I add in multiple textures and differing wall heights, but it is all prototyped.

To all a very happy, healthy 2020!
