Game.Prefabs.TerrainPropertiesData

Assembly:
Namespace: Game.Prefabs

Type: struct

Base: Unity.Entities.IComponentData, Unity.Entities.IQueryTypeParameter

Summary:
TerrainPropertiesData is an empty (marker/tag) component type used by the ECS to identify entities that represent terrain-related properties. The struct is decorated with [StructLayout(LayoutKind.Sequential, Size = 1)] so it has a non-zero size despite carrying no fields — this is a common pattern for tag components in Unity.Entities to ensure they are handled correctly by the runtime. Because it implements IQueryTypeParameter it can be used in query expressions (e.g., WithAll()) to filter entities.

Usage Example

using Unity.Entities;

public partial class TerrainExampleSystem : SystemBase
{
    protected override void OnCreate()
    {
        base.OnCreate();

        // Example: create an entity and add the tag component
        var entityManager = World.DefaultGameObjectInjectionWorld.EntityManager;
        Entity archetypeEntity = entityManager.CreateEntity();
        entityManager.AddComponentData(archetypeEntity, new TerrainPropertiesData());
    }

    protected override void OnUpdate()
    {
        // Query all entities that have the TerrainPropertiesData tag
        Entities
            .WithAll<TerrainPropertiesData>()
            .ForEach((Entity e) =>
            {
                // Perform logic for terrain-tagged entities
            })
            .ScheduleParallel();
    }
}
