singleton-patterns-config-and-access

What problem does it solve?

This Skill helps you model world-unique DOTS data safely so every system can access it fast without first-frame races or accidental duplicates.

Core Features & Use Cases

• O(1) singleton access with SystemAPI.GetSingleton<T>() for read-only consumers that need fast, unambiguous config or registries.
• Hard gating for bake readiness using state.RequireForUpdate<T>() so systems don’t run before the singleton entity exists.
• Safe producer/consumer writes using SystemAPI.GetSingletonRW<T>() for systems that snapshot or update singleton state once per frame, typically for input state.
• Bake-time correctness guidance ensuring exactly one Baker produces each singleton type and explaining how scene merge collisions happen.

Quick Start

Ask your agent to refactor a DOTS config/registry system so the config is implemented as a baked singleton component with state.RequireForUpdate<T>() and then accessed by readers using SystemAPI.GetSingleton<T>().
