Koota ECS

Koota manages state using entities with composable traits.

Glossary

Entity - A unique identifier pointing to data defined by traits. Spawned from a world.
Trait - A reusable data definition. Can be schema-based (SoA), callback-based (AoS), or a tag.
Relation - A directional connection between entities to build graphs.
World - The context for all entities and their data (traits).
Archetype - A unique combination of traits that entities share.
Query - Fetches entities matching an archetype. The primary way to batch update state.
Action - A discrete, synchronous data mutation (create, update, destroy). Reusable from any call site.
System - A reactive orchestrator that observes state changes and coordinates work, including async workflows. Runs in the frame loop or event callbacks.
