TRAD Strike

A small Raiden Trad-inspired vertical shooter written in C99, built on Sokol and a tiny ECS. The same binary runs natively and in the browser via WebAssembly.

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.

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 for graphics, app, and input across Metal, OpenGL, and WebGL2
  • 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
