Скачать или смотреть Built From Scratch: 2D Game Engine - Interactive Hierarchy and Selection

Welcome to the episode where the editor comes alive. We're connecting the event system we built last time to the UI, making the hierarchy panel display real entities, and adding selection so you can click and interact with your game world.

By the end of this episode, you'll transform your static editor UI into an interactive tool that responds to every change in your game world.

What You'll Build:
• Live entity list in the hierarchy panel
• Entity selection system with visual feedback
• Base component with human-readable entity names
• Event-driven UI updates using React state
• Centralized type definitions for components
• Foundation for inspector panel and property editing

Perfect for: Anyone who's followed along through Episode 6, or developers who want to learn how to build reactive editor interfaces with event-driven architecture.
