⚙️ An open-source ECS engine built from ground up in Scala 3

Basalt Engine

An ECS¹ engine built from ground up in Scala 3 with architectural support for Cats Effect and modularity in mind.

Roadmap

• Entity composition
• Platform-agnostic object and event abstraction
• Synchronous (main-thread) code execution
• Input/output support in queries with FS2
• State/scene preservation and loading
• Query composition with entities and streams
• Data persistence and (de)serialization to Circe

Background

Inspired by Bevy Engine – a data-driven game engine written in Rust – ECS implementation, we focus on logic built on top of resources, entities, and systems (could be simplified as data and functions). This approach is really nice because it's a very flexible and powerful design pattern that allows code to be easily reused, extended, and quickly written.

Reference

¹: Software architectural pattern "Entity component system".
