helios - Exploratory Development of an ECS-based Game Engine​

All set and done, project goal reached!

Well, almost...

The project quickly shifted away from its initially intended focus on gameplay and graphics implementation toward a deeper engagement with engine architectures, and the result breaks with classical OOP paradigms: In the report I published today (the engine document), I document this transition from deep inheritance hierarchies to a data-oriented (DOD) system.

In my previous post, I outlined the high-level separation between Commands and Events in helios, along with the basic double-buffered EventBus and CommandBuffer concepts. Since then, I've iterated significantly on the architecture, and I'm excited to share what has emerged: A Phase/Pass structure that provides much finer control over when events become visible and when commands execute.

Over the past few weeks, I’ve been busy refining the helios GameLoop to enable player interactions with various GameObjects. This included, in particular, controlling the player ship, spawning enemies, and - the holy grail of every game - the collision system.
