UCLASS() class MYGAME_API AMyActor : public AActor { GENERATED_BODY() public: AMyActor(); UPROPERTY(EditAnywhere, BlueprintReadWrite) int32 MyProperty; };This code defines a new actor class that is derived from the AActor class in the Unreal Engine. The class has a single "MyProperty" member that can be edited in the editor, and is available to Blueprint scripts. The package library for UObject is the Unreal Engine itself, which provides the framework for creating and executing game code. Additionally, a number of plugins and third-party libraries can be used to extend the functionality of the engine and add new features to the game.
