I took a few days to dive into how I could compute indirect lighting in my game, and it was easier than I thought to get a working system. I like the result, it already adds a lot to the scene. But it still needs more work! #screenshotsaturday #gamedev

Early this week, I added a few things to the profiler I’m using in the codebase, including sorting, navigating the hierarchy, in the code being able to customize the name of the area, and a visual line display. It’s entirely based on the Iprof runtime code. #screenshotsaturday #gamedev

For today, I don’t have much to show; I lost my mind with this spatial grid optimization... pure rabbit hole. In the end, it’s not worth it for mesh culling (at the moment), but definitely worth it for querying the near entities for collision detection and raycasting! #screenshotsaturday #gamedev

Painting the ground... #screenshotsaturday #gamedev

I recently worked on the ability to swap scenes in the game, and from there, I ended up adding a new menu. #indiedev #gamedev #indiegames

Recently I added some optimizations though, since the number of samples directly influences the vertex count, it can get out of control fast. So the sample count is computed from the sharpness of the corner angle now. It works pretty well! #indiedev #gamedev

So now I can meticulously design the labyrinth by just placing points, the curvature will pass through each of them (Catmull-Rom behind). I can also add or remove points on the spline, move their positions, slice the wall, undo/redo. #indiedev #gamedev #indiegames

A few month ago, I added a nice tool: a spline-based wall editor. Because the game is set in a vast and hand-crafted labyrinth, we needed ways of easily editing it. I wanted a labyrinth that looks sinuous, messy, and chaotic, so smooth curves were absolutely needed. #indiedev #gamedev #indiegames

I added the ability to paint the terrain, so now there’s a blend map with four channels. The RGB channels are used to weight the different attached textures, and the alpha channel creates holes in the terrain. #indiedev #gamedev #indiegames

To integrate this terrain system to my collision system, I simply convert the position of the player from world space to the terrain’s grid space, cut a small area around it, then reconstruct triangles to test against.

Last week, I added a simple terrain editor for my game. The terrain can be molded with a detail density of one meter, and the mesh is divided into 256 smaller chunks for rendering and editing purposes.

After a battle of many hours, SSAO is finally working okay now on the Metal backend. There's still some artefacts but it's pretty easy to fix them up.
