• Cataclysm-DDA

  121 4,919 10.0 C++

  Cataclysm - Dark Days Ahead. A turn-based survival game set in a post-apocalyptic world.

  Project mention: Pump action shotguns? | reddit.com/r/cataclysmdda | 2021-02-24

  Anyway, this actually once caused a "but muh realisms" argument back in the old days when I was still a contributor. Basically, a long time ago I added the Sten SMG to the game. I wanted to be able to add the means to craft it, because that's a thing that more or less makes sense. Kevin was hardcore against that, and his reasoning about it being real damn hard to make without machine shop tools makes sense. But at the time, I felt it was odd because there appeared to be craftable semi-auto firearms ALREADY in the game. IRL, semi-auto actions are actually simpler to make than a full-auto-only firearm.

  Project mention: Best Vulkan wrapper / low-level graphics library? | reddit.com/r/GraphicsProgramming | 2021-02-09

  (Sorry for a self-promo, hope that's fine.) If you don't mind being an early adopter and use something that's still undergoing heavy development and is not complete yet, I'm building a low-level Vulkan wrapper in Magnum. If you aren't familiar with Magnum yet, it's a C++11 library that has (among other things) a thin OpenGL/GLES/WebGL wrapper that removes the platform-specific extension hell and most of the boilerplate while still allowing you to work with the raw APIs if you need ... and the same is now being done for Vulkan.

  Or if you'd rather do a bit less coding, Construct 3 or GDevelop? Both of those are decent 2D engines with visual scripting. You can also try out both of them in the browser, so you can decide if you like them without having to download anything. (There are full local versions too, it's just convenient to be able to test something really quickly in a browser to see if you like it).

  Project mention: [Linux] Preferences.ini keeps resetting itself | reddit.com/r/Stepmania | 2021-02-24

  Can you try upgrading to 5.1.0-b2? This is the latest stable (despite the "beta" name) release of StepMania before 5.3. On Linux, you will need to compile it from source (compilation instructions are provided, but use git clone --branch v5.1.0-b2 --depth=1 https://github.com/stepmania/stepmania.git instead of git clone --depth=1 https://github.com/stepmania/stepmania.git in step 2 otherwise you'll get the latest unstable version of the code rather than the 5.1.0-b2 release).

  Project mention: Text Hooking Sakura, Moyu | reddit.com/r/visualnovels | 2021-02-09

  Hmm. Okay. I tried ITHVNR with the latest vn that I have and encountered the same problem. I think you're better off using Textractor since it's updated to work with the latest titles.

  Project mention: Some early gameplay from my voxel game: Wanderers | reddit.com/r/VoxelGameDev | 2020-12-28

  For example, in this Notch article, he discussed using trilinear interpolation to speed up noise evaluation as well as to smooth out rough parts. But I tested, and both of his problems actually came mostly from using too many noise octaves. Minecraft used 16 octaves for each noise channel, and 8 octaves for the blending noise, when just 5-6 and 2-3 would be enough. The rest of the speed problems could be solved by implementing something to skip noise evaluations when they wouldn't matter, at least above/below max/min biome height if not dynamic octave skipping. See this screenshot difference.
