Two years ago, I was Porting my JavaScript Game Engine to C for No Reason. I have since found a reason: making a new N64 game! The result is Xibalba 64 – a Wolfenstein 3D-like FPS. Modretro agreed to publish the game as a physical launch ti…
The build/run instructions for the example games for high_impact were subtly wrong: make sokol compiles the Sokol version, converts all assets and puts the results (executable and converted assets) into the build/ directory. So far so good.…
tl;dr: high_impact is small game engine for 2D action games. It's written in C, compiles to Windows, Mac and Linux as well as to WASM for the Web. It's “inspired by” my original Impact JavaScript game engine from 2010. The name high_impact
The source code for the classic PSX launch title wipEout was leaked in 2022. A few month ago I finally sat down to take a look at it. The result is a (nearly) complete rewrite that compiles to Windows, Linux, macOS and WASM. Thanks to WASM
Audio formats typically fall into one of three categories: “lossless”, “complicated” or “bad”. After developing a simple image format last year, I tried to come up with an audio format that fits neither of these categories. In other words:
Introducing QOI — the Quite OK Image Format. It losslessly compresses RGB and RGBA images to a similar size of PNG, while offering a 20x-50x speedup in compression and 3x-4x speedup in decompression. All single-threaded, no SIMD. It's also
This was my third time participating in the js13kGames contest. I won in 2018 with Underrun and utterly failed to deliver any compelling gameplay with my 2019 entry Voidcall. This year's theme was “Space” – I chose to completely ignore it a…
Like last year with Underrun, I participated in this year's js13kGames – a JavaScript game development competition with a file size limit of 13kb, including code, assets and everything else. My entry was Voidcall, a Real-time Strategy game.…
If you want to play videos in a native app or game you basically have three options: A few weeks ago I had this conversation on Twitter, where I offered a possible fourth solution: (Link to this thread on Twitter) MPEG1 is a very old format…
I participated in this year's js13kGames, a JavaScript game development competition with a file size limit of 13kb, including code, assets and everything else. My entry was Underrun, a twin stick shooter using WebGL. Play Underrun – A WebGL…
A few years ago I started to work on an MPEG1 Video decoder, completely written in JavaScript. Now, I finally found the time to clean up the library, improve its performance, make it more error resilient and modular and add an MP2 Audio dec…
Edit: as of September 13, 2016 Apple introduced a native API to manipulate Typed Arrays as part of iOS 10. This makes this whole article obsolete, if still technically interesting. Back when the HTML5 Canvas element was introduced by Apple
