UObject

UObject is the fundamental base class for all objects in Unreal Engine. It provides the core functionalities for object management, serialization, and reflection within the engine. Every class in Unreal Engine that derives from UObject gains access to a powerful system that allows for dynamic instantiation, property editing through the editor, and network replication.

Key features of UObject include its reflection system, which enables the engine to inspect and manipulate object properties at runtime. This reflection is crucial for features like the Unreal Editor's property editor, serialization of game data, and dynamic function calls. UObjects can be garbage collected by the engine, helping to manage memory efficiently.

Furthermore, UObject supports a robust system for class and property definition, allowing developers to declare and define new types and their attributes. This object-oriented foundation is central to the Unreal Engine's architecture, facilitating the creation of complex game worlds and systems.
