How do I make an inventory system in Godot 4?

To create an inventory system in Godot 4: 1) Create custom Resource classes for item definitions with properties like name, icon, and stack size. 2) Build an Inventory class using arrays or dictionaries to store item slots. 3) Design a grid-based UI with TextureRect nodes for item icons. 4) Implement drag-and-drop using Godot's built-in drag system. 5) Add item usage functionality for consumables. The key is separating data (Resources) from display (UI) for a clean architecture.

Add a 'max_stack_size' property to your item Resource. When adding items, check if the same item type exists and has room in its stack. If so, increase the count instead of adding a new slot entry.
