This Skill provides a high-performance ECS framework for Roblox Luau via TypeScript bindings, enabling scalable world simulation and data-oriented design.
Install the library in your Roblox TypeScript project, create a world, declare components with world.component<T>(), and start using world.query to drive game logic. Start by defining components, then use world.set or world.add to attach data and world.query to process systems each frame.

A high-performance ECS framework for Roblox Luau enables scalable game architecture by using archetype-based storage for cache locality, supporting large entity counts and deterministic batched updates for world simulation.
Querying entities in a Roblox TypeScript project uses a rich query system that supports components, tags, and relationships, including wildcard targets, to efficiently retrieve and process matching entities each frame.
Managing component lifecycles in a Luau ECS is handled through hooks and signals, allowing you to monitor external observers and trigger deterministic batched updates when component data changes.
This Roblox ECS supports relationships like parent-child hierarchies through a rich query system that handles pair constructs, such as pair(ChildOf, parent), including matching wildcard targets for flexible entity grouping.
A Roblox-TS setup is required to develop with this Luau ECS, as it relies on the rbxts package ecosystem and provides type-safe APIs for TypeScript bindings to ensure scalable world simulation.
Optimizing hot-path code in a Roblox ECS is achieved through optional direct archetype access, bypassing standard APIs to maximize performance for systems processing large entity counts.
