   I made a web game called Almost Pong▲1,135

   Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!

   ClojureScript pixel game engine with Blender live-reloading▲285

   Hi HN! 2d spritesheets for game development are often distributed as a PNG image, sometimes with a separate JSON or XML metadata document describing the layout, including any animation sequences within the sheet. Sometimes there is no metadata document and you have to work it out and manually write custom code to chop up the spritesheet and reference the sprites you want. I think it would be good if it became standard practice to distribute spritesheet PNGs with the metadata inline inside a PNG "chunk" so the whole thing is self-contained. That way artists can just distribute one file, and…

   Consol3 – A 3D engine for the terminal that executes on the CPU▲170

   Hi all This has been my hobby project for quite a few years now It started as a small engine to serve as a sandbox to try out new 3d graphics ideas After adding many features through out the years and re-writing the entire engine a few times, this is the latest state It currently supports loading models with animations, textures, lights, shadow maps, normal maps, and some other goodies I've also recently added voxel raymarching as an alternative renderer, along with a fun physics simulation :)

    I wrote a technical history book on Lisp▲252

    The book page links to a blog post that explains how I got about it (and has a link to sample content), but the TL&DR is that I could not find a lot of books that were on "our" history _and_ were larded with technical details. So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my…

    Clx – Compile Lua to Native Executables Through C++20▲143

    Hi HN, clx is an ahead-of-time compiler for standard Lua that generates C++20 and produces standalone native executables through GCC, Clang or MSVC. The project started as an experiment to see whether modern C++ could be used as a portable compiler backend instead of LLVM or direct machine code generation. The generated code is then compiled and optimized by the host toolchain. The latest release replaces the previous NaN-tagged value representation with a new shadow-types implementation, adds full int64 support, improves native arithmetic code generation and adds ARM64 macOS coroutine…
