I sometimes pick up random projects just because I can, this was one of those times. I made it as a week long project a while back this year but never shared here, so thought to go for it haha. I created a game inspired by Doom and the backrooms called The Backdooms under 2.4kb in minified html. (for reference, this entire post would be around 1.8kB haha) I had to use a not popular way of using GZip with Zlib headers (had to write my own script for compressing it, also in the repo) to eventually convert it a size 40 QR code that works right in your browser using Decompressionstream API. This…

I made a Doom source port that runs within a PDF file. I was inspired by the recent HN post about Tetris in a PDF (https://news.ycombinator.com/item?id=42645218) and I wondered if I could get Doom to run using a similar method. It turns out that old versions of Emscripten can compile C to asm.js code that will happily run inside the limited JS runtime of the PDF engine. I used the doomgeneric (https://github.com/ozkl/doomgeneric) fork of the original Doom source, as that made writing the IO fairly easy. All I had to do was implement a framebuffer and…

Hello HN! We’re a small creative studio specializing in real-time 3D experiences. Netlify approached us to design and build an interactive experience to celebrate reaching 5 million developers. Inspired by the classic game Marble Madness, we created a gamified experience where users control a ball through playful, interactive levels. The goal was to blend marketing content with the look and feel of a game to engage users. The app is built with Three.js [1], using our custom render pipeline and shaders, and uses Rapier for physics simulation [2]. The 2D content is overlaid on the WebGL view…

I got DOOM running in KiCad by rendering it with PCB traces and footprints instead of pixels. Walls are rendered as PCB_TRACK traces, and entities (enemies, items, player) are actual component footprints - SOT-23 for small items, SOIC-8 for decorations, QFP-64 for enemies and the player. How I did it: Started by patching DOOM's source code to extract vector data directly from the engine. Instead of trying to render 64,000 pixels (which would be impossibly slow), I grab the geometry DOOM already calculates internally - the drawsegs[] array for walls and vissprites[] for entities. Added a…

Recently, I managed to recover some of my earliest work from the ZX Spectrum era from an old audio cassette. It is a mini-game, that I created as a teen, called "Atomix," written in BASIC with a mix of Z80 assembly — some of which I coded myself, while other parts were disassembled from existing games. I put the game in an modern emulator and recorded a screencast. See the video in my linkedin post: https://www.linkedin.com/feed/update/urn:li:activity:7288665...

I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…

I recently brought Infocom's original UNIX z-machine source code back to life on modern systems. The modified source code, instructions on usage, a build of the z-machine, and examples of embedded game executables are available. There is also a detailed write-up about the state of the original source code, the porting process, and the invaluable role Justine Tunney's Cosmpolitan project played in bringing the Zork trilogy (and more) to Windows/Mac/Linux/bsd for arm/x86 machines over the course of a lazy Sunday.

TrueType fonts have a hinting VM that grid-fits glyphs. It has a stack, storage area, conditionals, function calls, and it turns out it's Turing-complete. So I built a raycasting engine in the hinting bytecode. The glyph "A" in the font has 16 vertical bar contours. The hinting program reads player coordinates from font variation axes via GETVARIATION, does DDA ray marching against a tile map in the storage area, and repositions bar heights with SCFS. It ends up looking like a crude Wolfenstein-style view. Small visuzlization:…

Wadzilla is currently a PoC. Although in theory it “works”, it does not create an entertaining experience as a game, although to me it is quite fun just too see it output ZIL for all of the rooms in a DOOM WAD, with all of the objects in all of their correct locations by their plain English names, along with the 8-character names for the textures of the walls, floors, and ceilings in their relative positions in the room. Part of that enjoyment of course comes from knowing what it entails just to get that far, so the amount of entertainment you derive from that may be far less. In fact, I…

Hi HN, I’ve been working on Gore – a port of the classic Doom engine written in pure Go, based on a ccgo C-to-Go translation of Doom Generic. It loads original WAD files, uses a software renderer (no SDL or CGO, or Go dependencies outside the standard library). Still has a bit of unsafe code that I'm trying to get rid of, and various other caveats. In the examples is a terminal-based renderer, which is entertaining, even though it's very hard to play with terminal-style input/output. The goal is a clean, cross-platform, Go-native take on the Doom engine – fun to hack on, easy to read,…

Hello, Hacker News! My name is Lillian (see: http://about.lillian.link/), and I just released version 0.2 of my MIT-licensed game engine, Hypatia(http://lillian-lemmer.github.io/hypatia/). Hypatia is a game engine for single player 2D action adventure games. You can use it to make a game like Legend of Zelda: Oracle of Ages and Oracle of Seasons. Hypatia is aimed at non-programmers and programmers alike. I'm seeking any sort of feedback. Hypatia supports FreeBSD first, but has great support for just about any platform…

Demo: https://www.youtube.com/watch?v=f5uygzEmdLw Hi HN, I built a RISC-V emulator that implements the RV32IM instruction set and a minimal syscall interface to run DOOM. A few weeks ago, I got my first output with a simple hello world assembly program. Since then I have been working tirelessly to get DOOM to run. I needed to figure out how to run C programs first, and came across newlib, which allows the underlying environment to implement the syscall stubs one by one until the programs run. I have also added ELF loading, but currently only a single `PT_LOAD` segment is…
