The same binary runs natively and in the browser via WebAssembly. [Visit Project ](https://briansunter.github.io/trad/)[View Source](https://github.com/briansunter/trad) C Sokol WebAssembly Game Development ECS  ## Overview TRAD Strike is a small vertical shoot-‘em-up inspired by Raiden Trad, written in C99. The view is top-down and 2D, but every ship, projectile, and prop on screen is a real 3D mesh from the Kenney Space Kit, lit at asset-conversion time so the renderer does no lighting math at runtime.  TRAD Strike gameplay screenshot The same source builds to a native macOS/Linux binary and to a WebAssembly bundle, so desktop and mobile web both run the same gameplay code as the native build. ## Features - Wave-based vertical shooter with enemy waves, projectiles, particles, and pickups - ECS layout with `spawn`, `player`, `enemy`, `movement`, `collision`, `lifetime`, and `cleanup` systems - Desktop input via WASD/arrows, Space/Z/X to fire, R to restart, mouse aim - Mobile touch controls: left half is a d-pad, right half is the fire button - Parallax starfield and alpha-blended glow effects rendered through Sokol GL immediate-mode - Static C mesh data generated from Kenney OBJ models at build time, with no runtime model loading ## Technology Stack - C99 for all gameplay and rendering code - [Sokol](https://github.com/floooh/sokol) for graphics, app, and input across Metal, OpenGL, and WebGL2 - [c-ecs](https://github.com/briansunter/c-ecs) for entities, components, and systems - Emscripten for the WebAssembly build - Python tool that bakes Kenney OBJ meshes into static C arrays - Nix flake for a reproducible clang + emscripten dev shell ## Related projects - [Platform](/projects/platform) [A small 2D platformer rendered with isometric 3D models, written in C99 and built on Sokol and a tiny ECS.
