New Show Hacker News story: Show HN: Mini Metroidvania in 13KB of JavaScript

Show HN: Mini Metroidvania in 13KB of JavaScript
39 by arikgalactic | 21 comments on Hacker News.
As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript. The source is available here: https://ift.tt/knCJ6IB NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github. Useful hacks: - Using Roadroller ( https://ift.tt/oaGR3fm ) for compression - Compressing the map data as grayscale PNG paired with some code generation. - Using procedural animation for all characters. - Replacing string enum with numeric enums for compression. - Built a small game engine for object lifecycle and rendering. - Single function to generate unique procedural songs for different regions.

New Show Hacker News story: Show HN: Sora, Personal Publishing Platform

Show HN: Sora, Personal Publishing Platform 10 by chrispuska | 3 comments on Hacker News. We wanted to create, to express ourselves without being judged either by strangers or some algorithm. We wanted our own space on the internet, where our photos and words would matter. So we started to build an app that can showcase our content, without having to pick a platform. You can use Sora to publish a few different content types. - Blog - Polaroid - Poster - Microblog You can either display them all on your Sora profile as a summary (like mine https://ift.tt/x8oP2en ), or put any of them forward for the world to see. We plan to run this app for a long time and looking for feedback, so let us know what you think! (feedback@sora.city, or link on website) --- Our stack today is Node, Typescript, NextJS, atomic CSS, with everything stored on Supabase.

New Show Hacker News story: Show HN: KrotoDC – gRPC in Kotlin with Dataclasses

Show HN: KrotoDC – gRPC in Kotlin with Dataclasses 2 by mscheong | 0 comments on Hacker News. - A protoc plugin data class generator that can be used as a substitute for existing Java protobuf classes that need to be constructed by a builder (which isn't very kotlin-ish). - generates coroutine service base and stubs that use the generated classes as request/response types, allowing you to completely avoid using Java classes. - Since it also generates converter extension functions between the generated types and Java types, you can still easily use protobuf-specific features such as serialization. - Additionally provides Kotlin-specific features (optional fields as nullable, oneof fields as sealed classes).
