require-for-update-gate

What problem does it solve?

This Skill prevents ECS/Unity DOTS systems from running when required singleton or component prerequisites are missing, which eliminates boilerplate null-checks and avoids wasted scheduling work.

Core Features & Use Cases

• Precondition gating: Uses state.RequireForUpdate<T>() in OnCreate to ensure a system only runs when the required singleton or component type exists.
• Safe access pattern: Pairs the gate with SystemAPI.GetSingleton<T>() in OnUpdate, relying on the gate to guarantee presence.
• Combinable requirements: Supports AND-ing multiple RequireForUpdate calls so systems activate only when all conditions are satisfied.
• Use Case: Only activate a spawn/movement system when a SpawnerConfig singleton and a scene-scoped marker component exist, avoiding early-frame errors and unnecessary work.

Quick Start

Tell the AI to add state.RequireForUpdate<YourRequiredSingleton>() and state.RequireForUpdate<YourSceneTag>() in OnCreate, then use SystemAPI.GetSingleton<YourRequiredSingleton>() inside OnUpdate.
