Game.Citizens.Adult

Assembly: Assembly-CSharp (game runtime)
Namespace: Game.Citizens

Type: struct

Base: System.ValueType, implements Unity.Entities.IComponentData, Unity.Entities.IQueryTypeParameter, Colossal.Serialization.Entities.IEmptySerializable

Summary:
Adult is an empty/tag ECS component used to mark an entity as an adult citizen. It is annotated with [StructLayout(LayoutKind.Sequential, Size = 1)] so it occupies a single byte (avoiding a zero-sized type) and is compatible with the game's serialization system (IEmptySerializable). As a marker component it carries no data and is intended for queries, filters, and conditional logic in Systems and Archetypes.

---

Fields

• This struct defines no instance fields. It is intentionally empty (used as a tag component).

Properties

• None

Constructors

• public Adult()
  This is the default (implicit) parameterless constructor for the struct which yields the default value. No custom constructor logic is provided.

Methods

• None (no methods are defined on this type). It implements the marker/serialization interfaces but provides no custom members.

Usage Example

using Unity.Entities;
using Game.Citizens;

// Add the tag to an entity
EntityManager em = World.DefaultGameObjectInjectionWorld.EntityManager;
Entity e = em.CreateEntity();
em.AddComponentData(e, new Adult());

// Query entities that are adults inside a SystemBase
public partial class ExampleSystem : SystemBase
{
    protected override void OnUpdate()
    {
        Entities
            .WithAll<Adult>()
            .ForEach((Entity entity) =>
            {
                // handle adult citizen entity
            })
            .WithoutBurst()
            .Run();
    }
}

{{ Notes for modders }}
- Because Adult is an empty tag component, prefer AddComponentData(new Adult()) or AddComponent() when modifying entity compositions.
- The StructLayout attribute with Size = 1 ensures compatibility with serialization and any native layout expectations in the game's pipeline.
