Big update this week!

My voxel renderer now has the capability to overlay everything with any texture I want. I'm using it on a new set of interconnected winter levels. This way I don't have to manually come up with a frosty version of each texture.

Without giving away too much, this week I built a new system that has implications for both puzzle solving and movement mechanics.

I also went back to several levels and fiddled with lighting again. Basically 90% of my development time is spent adjusting colors. Before / after:

Clearly, the old version relied heavily on bloom. I'm trying to avoid that a bit more now. Bloom is like crack cocaine to game developers.

Other random things:

  • When you walk off an edge, there is now a split second of forgiveness during which you can still jump. Just filing down another edge to make player movement less frustrating.
  • I finally killed an old glitch that subconciously annoyed me for years. Lemma has "bullet time", and up until this week it stuttered noticeably when running in slow-motion, despite maintaining a high framerate. I peeked into the BEPUPhysics source code and realized it runs on a fixed timestep with an accumulator. It updates at 60 FPS regardless of the actual framerate. So when I changed the time scale, that 60 FPS dropped to 30 FPS. But no more! I now scale BEPUPhysics' target framerate as well, and the result is silky smooth slow motion.
  • I liked using Jekyll for my blog so much, I also migrated the Lemma website, and updated it in the process. The site was already hosted on S3 so half the work was already done.

That's it for this week. Thanks for reading!

Eventually. It will require a switch from XNA to MonoGame. I've already contributed some code to MonoGame to fill in some of the missing features that Lemma needs, but it's still a long way off.

Okay, so there's a problem.
I got an error saying "Could not find a Direct3D Device that supports the XNA Framework HiDef Profile."
Do you have any idea why that would be?
I've looked around, can't seem to find a solution other than the fact that I need to upgrade my computer which at the time will be impossible, being that I'm poor.

Yeah, it sounds like your graphics card isn't supported. Unfortunately you need a Direct3D 10 graphics card to play Lemma at the moment. In the future I might consider supporting older graphics cards, but it would require a complete rewrite of the rendering system. Sorry. :/

I've been looking for more parkour games.
The fact that this looks VERY impressive, and I can download it for free, gives it a high rating at the start. I'll give it a go. Nice job, really, this type of game is rare and I've been dying for a new one.

I cannot change the screen resolution. Am I doing something wrong, or have you not added that option?

Sorry, it's not the most obvious control scheme. Mouse over the resolution and scroll with the scroll wheel. When you exit the pause menu it will change the resolution.
