Inventory System

Manages item slots, inventory UI, and item add/remove operations, with save-data integration.

Quick Integration

1. Copy the files

GUI/pause_menu/Inventory/
├── inventory_data.gd       # Inventory data (Resource)
├── slot_data.gd            # Slot data (Resource)
├── inventory_ui.gd/.tscn   # Inventory UI
└── inventory_slot_ui.gd    # Inventory slot UI component

2. Create an inventory data resource

Create player_inventory.tres with type InventoryData:

# inventory_data.gd
class_name InventoryData extends Resource

@export var slots: Array[SlotData]  # Slot array

func add_item(item: ItemData, count: int = 1) -> bool:
    # Try stacking first, then look for an empty slot
    ...

3. Usage example

# Add items
var inventory: InventoryData = preload("res://Inventory/player_inventory.tres")
inventory.add_item(apple_item, 5)

# Use an item
inventory.use_item(potion_item, 1)
