The Property bag is the cornerstone of Unity.Properties—a powerful system that lets you generically access, inspect, and modify object data at runtime without reflection. In this video, we’ll show you how property bags, visitors, and adapters work together to build flexible, high-performance systems for tooling, UI binding, data validation, and more. You’ll learn how to write your own visitors, construct property paths, and use these patterns to create runtime features that adapt to any data structure. Whether you're building custom inspectors, debug panels, or save systems, this deep dive will change how you think about structured data in Unity.
