DisplayArea

Concrete TableArea subclass for shop display surfaces. Inherits all item management, collision detection, and positioning behavior from TableArea without adding additional functionality.

Definition

Namespace: Paragon.Townskeep.ShopSystem Assembly: Townskeep.dll

public class DisplayArea : TableArea

Inheritance: MonoBehaviour → TableArea → DisplayArea

Remarks

DisplayArea is a marker subclass that identifies a TableArea as a display-only surface. It inherits all functionality from TableArea:

• Collision-based item tracking — OnTriggerEnter / OnTriggerExit automatically add and remove ShopItem wrappers as Item objects enter and leave the collider.

• Item list management — Maintains a list of ShopItem entries that can be queried for availability and reservation status.

• Positioning — Provides InnerSpot and OuterSpot transforms for item placement and approach points.

• Bounds — Exposes GetBounds() from the required BoxCollider.

DisplayArea serves as a semantic type to distinguish display surfaces from other TableArea types (e.g., TradingArea). This enables type-specific logic in interactions and agent actions.

All public API is inherited from TableArea:

Properties (inherited)

Property	Type	Description
InnerSpot	Transform	Position inside the table area (for item placement)
OuterSpot	Transform	Position outside the table area (for approach waypoint)

Usage Example

// DisplayArea is used as a typed reference for display-specific logic

if (display.HasAvailableItem)
{
    // Agent can approach this display to pick up items
    Transform approach = display.OuterSpot;
}
