Game.Prefabs.CitizenRequirementData

Assembly:
Game

Namespace:
Game.Prefabs

Type:
struct

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

Summary:
A plain ECS component that describes minimum requirements for a citizen-related prefab. It stores integer thresholds used by spawning/availability systems to determine whether a prefab is eligible (for example, a building or service that needs a minimum population or minimum happiness to appear/activate). Being a struct implementing IComponentData, it is a blittable data container suitable for use in jobs and queries.

---

Fields

• public int m_MinimumPopulation
  Minimum required population for the prefab to be considered available/valid. Typical use: compare current city population against this value. Default value is 0 when the struct is default-constructed.

• public int m_MinimumHappiness
  Minimum required happiness value for the prefab to be considered available/valid. Typically expressed on the same scale the game uses for happiness (commonly 0–100); default is 0.

Properties

• None.
  This type exposes only public fields and does not declare properties.

Constructors

• public CitizenRequirementData()
  Implicit parameterless/default constructor provided by C# for structs. You can also construct with an object initializer: new CitizenRequirementData { m_MinimumPopulation = 100, m_MinimumHappiness = 75 };

Methods

• None.
  This component contains only data. Any logic that interprets these values should live in systems or jobs that read this component.

Usage Example

// Add the component to an entity (EntityManager example)
var requirements = new CitizenRequirementData {
    m_MinimumPopulation = 500,
    m_MinimumHappiness = 60
};
entityManager.AddComponentData(prefabEntity, requirements);

// Read in a SystemBase using Entities.ForEach
public partial class PrefabAvailabilitySystem : SystemBase
{
    protected override void OnUpdate()
    {
        int currentPopulation = /* obtain from game state */;
        int currentHappiness = /* obtain from game state */;

        Entities
            .WithAll<SomePrefabTag>()
            .ForEach((Entity e, in CitizenRequirementData req) =>
            {
                bool isAvailable = currentPopulation >= req.m_MinimumPopulation &&
                                   currentHappiness >= req.m_MinimumHappiness;
                // handle availability (enable/disable prefab, set flags, etc.)
            }).Run();
    }
}

// Or read via EntityManager
var reqData = entityManager.GetComponentData<CitizenRequirementData>(prefabEntity);
if (gamePopulation >= reqData.m_MinimumPopulation && gameHappiness >= reqData.m_MinimumHappiness)
{
    // allow spawning or mark as unlocked
}
