Скачать или смотреть Ultimate Minecraft-Style Inventory in Godot 4 (Full Course)

In this complete Godot 4 tutorial series, you build a clean, scalable, and fully modular inventory system from scratch. The focus is on architecture first, implementation second. Every mechanic is explained at the logic level before code is written, so the system remains extensible for real production games.

This tutorial covers the full lifecycle of an item, from world representation to UI storage and manipulation.

What you will learn
Inventory system architecture based on data flow, not hacks
Item metadata design using Resource classes
World item vs inventory item separation
Greedy item pickup and stacking logic
Per-item max stack handling
Dropping items from inventory back into the world
Mouse-based drag and drop using Godot UI APIs
Item swapping, stacking, and replacement logic
Minecraft-style item splitting with right-click behavior
Backend-driven inventory logic with frontend UI synchronization
Signal-based updates for clean UI refreshes

Core concepts explained
ItemData as immutable item blueprints
InventoryItem as mutable item containers
Inventory as backend state manager
Inventory UI as a pure visual frontend
Safe drag-and-drop validation
Data integrity across pickup, drop, and UI interactions

System features
Clean separation of concerns
Scalable slot-based inventory
Supports stackable and non-stackable items
Works for both 2D and 3D Godot projects
Designed for extension into crafting, equipment, and containers

This series is intended for developers who want a production-grade inventory system rather than a quick demo. By the end, you will fully understand the logic, data flow, and structure required to implement your own inventory system without copying code blindly.
