tag-component

What problem does it solve?

This Skill solves the challenge of labeling entities with logical state so systems can include or exclude them efficiently without adding storage or per-entity data fields.

Core Features & Use Cases

• Empty tag component: Defines an IComponentData struct with no fields to represent membership or a boolean-like state.
• Safe, query-driven gating: Uses RequireForUpdate<T>() to conditionally run systems and query filters like WithAll<T>() / WithNone<T>() to select entities based on tag presence.
• Zero-chunk-overhead intent: Achieves stateful dispatch by structural archetype membership rather than runtime checks, enabling clear system composition.

Quick Start

Ask the AI to show how to create an empty IComponentData tag (e.g., IsActiveEnemy), gate a system with state.RequireForUpdate<IsActiveEnemy>(), and filter entities with Query().WithAll<IsActiveEnemy>() while adding/removing the tag via an ECB outside iteration.
