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 stupidly simple .
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 is a nod to a time when C was considered a high level language.
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!
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.
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.
Last month I announced a toy project called 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.
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 decoder and MPEG-TS demuxer. This makes this library not just an MPEG decoder, but…
My HTML5 Game Engine Impact is now ready. It took some time, but I think it was worth it. I'm proud of what I have achieved and I hope you'll like it too.
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.
Did you ever wonder why explosions and other effects looked so much cooler on the original PlayStation than they did on the Nintendo 64?
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.
Less talk, more action – Apple just approved two of my JavaScript games for the AppStore: Biolab Disaster and Drop . Both are free; go check them out. You can also play them in your browser here and here .
I know you're waiting for the release of the Impact Game Engine , and I promise you, it's coming. I just get distracted too easily. So here's my game Biolab Disaster running on the iPhone 3GS with 60 frames per second:
tl;dr: pl_synth is a tiny music synthesizer for C & JS and an editor (“tracker”) to create instruments and arrangements.
