I’m building a reusable 3D game engine from scratch using ECS architecture, JavaScript, and Three.js. This channel focuses on step-by-step game engine programming, including camera systems, character controllers, collision, event buses, inventory, RPG mechanics, and multiplayer-friendly architecture.
