Doom-Style Map Editor and Engine Progress Update

October 5, 2025

I used the weekend to add some quality-of-life features, improve error handling, and implement additional edge case logic for portal creation in the Portals Editor.

Until now, it wasn't possible to change a sector's winding, which meant you had to completely remove and recreate the sector. I've added the ability to toggle the winding now, along with winding markers in the editor so you can easily see if a sector has the correct winding. There's also a new screenshot on the projects page showcasing this feature.

On the engine side, I've been improving the renderer. I also worked on collision detection: it's now possible to walk on slopes.
