## Overview

This is a Unity inventory-module project: players add, remove, and inspect items through containers, with slots and inventory implementations holding item data and display modules presenting container contents. The README also describes dynamic/multiple inventories, restrictions, identity management, and compressed saving, but labels several of these as TODO or under consideration. The tree supports representing those as planned capabilities; sampled code directly confirms only the player-to-container calls and slot behavior, so other wiring is omitted.

Main entry points: [`TempScript/PlayerInventory.cs`](https://github.com/minroy/learn_unity/blob/main/TempScript/PlayerInventory.cs) (Inventory example), [`Assets/InventoryModuleGeneric`](https://github.com/minroy/learn_unity/tree/main/Assets/InventoryModuleGeneric) (Container facade), [`TempScript/DisplayModule.cs`](https://github.com/minroy/learn_unity/blob/main/TempScript/DisplayModule.cs) (Display module), [`Assets/InventoryModuleGeneric/SlotsHandlerGenerics/Slot.cs`](https://github.com/minroy/learn_unity/blob/main/Assets/InventoryModuleGeneric/SlotsHandlerGenerics/Slot.cs) (Slot handler)
