Game.Buildings.ResourceProducer

Assembly: Assembly-CSharp
Namespace: Game.Buildings

Type: struct

Base: System.ValueType, IComponentData, IQueryTypeParameter, IEmptySerializable

Summary: ResourceProducer is an empty ECS (Entity Component System) marker component used to tag entities that act as resource producers in the game. It is laid out with a 1-byte size (StructLayout Size = 1) so serialization and native layout requirements are satisfied even though it contains no data. Implementing IComponentData makes it usable in Unity's ECS, IQueryTypeParameter allows its use in query/type filters, and IEmptySerializable ensures proper handling by the game's custom serialization.

Fields

• This struct declares no instance fields. It is intentionally empty and used as a tag/marker component to identify resource-producing entities in ECS queries and systems. {{ The StructLayout attribute sets the size to 1 byte so the type is non-zero-sized for native/serialization expectations. }}

Properties

• This type exposes no properties. It is purely a marker component. {{ Use this component in queries or to add/remove the marker on entities via EntityManager or system APIs. }}

Constructors

• public ResourceProducer() {{ The default parameterless constructor is provided implicitly by the runtime. Because the struct is empty, no custom initialization is required. }}

Methods

• This type defines no methods. It is an empty marker component. {{ Interaction is performed via ECS APIs (Add/Remove component, WithAll/WithNone queries, etc.). }}

Usage Example

using Unity.Entities;
using Game.Buildings;

// Create an entity with the ResourceProducer tag
public partial class ResourceProducerBootstrapSystem : SystemBase
{
    protected override void OnCreate()
    {
        base.OnCreate();

        // Create a new entity and add the marker component
        var archetype = EntityManager.CreateArchetype(typeof(ResourceProducer));
        var entity = EntityManager.CreateEntity(archetype);

        // Or add the marker to an existing entity:
        // EntityManager.AddComponent<ResourceProducer>(existingEntity);
    }

    protected override void OnUpdate() { }
}

// Querying entities that have the ResourceProducer tag
public partial class ResourceProducerProcessingSystem : SystemBase
{
    protected override void OnUpdate()
    {
        Entities
            .WithAll<ResourceProducer>()
            .ForEach((Entity e, in SomeOtherData data) =>
            {
                // Process resource-producing entities here
            })
            .ScheduleParallel();
    }
}

{{ Because ResourceProducer is a tag, prefer AddComponent/RemoveComponent or archetypes to mark entities, and use WithAll() (or WithNone()) in queries to filter by this marker. }}
