Table

Root MonoBehaviour for a shop surface. Coordinates an Interactable, a TableNetwork, and a TableArea to provide item availability queries and interactable shop behavior. Serves as the entry point for game code to query which items are on the table and available for trade.

Definition

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

public class Table : MonoBehaviour

Inherits: MonoBehaviour

Remarks

Table is a thin coordination layer. It discovers its child components in Awake():

• Interactable — on the same GameObject, provides interaction system integration

• TableNetwork — on the same GameObject, handles network trigger registration

• TableArea — on a child GameObject, manages the physical item detection zone

All item queries delegate to tableArea.Items with filtering. GetItem() returns the first unreserved ShopItem, while HasAvailableItem checks if any unreserved items exist. HasAnyItem checks for any items regardless of reservation state.

Quick Lookup

Goal	How
Check if table has items	table.HasAnyItem
Check if unreserved items exist	table.HasAvailableItem
Get first available item	table.GetItem() — returns null if none
Access the trigger area	table.Area
Access the Interactable	table.Interactable

Properties

Interactable

public Interactable Interactable { get; }

The Interactable component on this GameObject, used by the interaction system.

Area

public TableArea Area { get; }

The child TableArea that detects items entering/leaving the table bounds.

HasAnyItem

public bool HasAnyItem { get; }

Whether the table has any items (reserved or unreserved). Delegates to tableArea.Items.Any().

HasAvailableItem

public bool HasAvailableItem { get; }

Whether the table has at least one unreserved item. Delegates to tableArea.Items.Any(item => !item.IsReserved).

Methods

GetItem

public ShopItem GetItem()

Returns the first unreserved ShopItem on the table, or null if no available items exist.

Returns: The first ShopItem where !IsReserved, or null.

Lifecycle

Awake()
  ├─ interactable = GetComponent<Interactable>()
  ├─ tableNetwork = GetComponent<TableNetwork>()
  ├─ tableArea = GetComponentInChildren<TableArea>()
  └─ tableNetwork.Initialize(this)

Common Pitfalls

TableArea must be a child GetComponentInChildren<TableArea>() discovers the area in children. The TableArea must be on a child GameObject, not a sibling or parent.

GetItem() returns null when empty FirstOrDefault() returns null when no unreserved items exist. Always null-check the result before using it.

All three components required Table expects Interactable, TableNetwork, and TableArea to be present. Missing any of them causes a NullReferenceException in Awake().
