Game.Net.TrainTrack

Assembly: Game
Namespace: Game.Net

Type: struct

Base: System.ValueType, implements IComponentData, IQueryTypeParameter, IEmptySerializable

Summary:
TrainTrack is an empty/tag component (1-byte sized struct) used with Unity.Entities (ECS) to mark or tag entities that represent train tracks in the game's entity/component model. The struct is explicitly laid out with Size = 1 so it is non-zero-sized (useful for serialization/interoperation). Because it implements IComponentData it is usable as a component in ECS; IQueryTypeParameter enables use in entity queries; IEmptySerializable integrates with Colossal's serialization helpers.

Fields

• This type declares no instance fields.
  Note: The struct is attributed with [StructLayout(LayoutKind.Sequential, Size = 1)] to force a size of 1 byte even though it contains no fields.

Properties

• This type declares no properties.

Constructors

• public implicit parameterless constructor (default struct constructor)
  This struct relies on the default value-initialized constructor (no explicit constructors are declared).

Methods

• This type declares no methods.

Usage Example

using Unity.Entities;
using Game.Net;

// Add the tag component to an existing entity
var em = World.DefaultGameObjectInjectionWorld.EntityManager;
em.AddComponentData(existingEntity, new TrainTrack());

// Query for all entities that are tagged as train tracks
EntityQuery trainTrackQuery = em.CreateEntityQuery(ComponentType.ReadOnly<TrainTrack>());

// In a SystemBase, iterate over entities that have the TrainTrack tag
public partial class ExampleTrainTrackSystem : SystemBase
{
    protected override void OnUpdate()
    {
        // Process entities that have the TrainTrack tag
        Entities
            .WithAll<TrainTrack>()
            .ForEach((Entity e) =>
            {
                // Your per-entity logic here
            })
            .WithoutBurst()
            .Run();
    }
}

Additional notes: - Use this struct as a marker/tag; it carries no data by design. - The IEmptySerializable interface indicates it participates in the game's custom serialization pipeline (Colossal.Serialization). - Because it is trivially small and stateless, it's efficient for filtering and tagging entities in queries.
