설명

Represents an array, list, struct or class.

The Generic type is used for compound types that are serialized in-line:
- Arrays and lists.
- Structs that are user defined (e.g. not a built in Unity type).
- Classes that are serialized 'by value' (e.g. referenced without the SerializeReference attribute).
- Certain built in Unity structs, when they do not have dedicated SerializedPropertyType enum value. For example RectOffset is Generic, but Vector3 is SerializedPropertyType.Vector3.


Note: The term Generic, when used as a SerializedProperty type, should not be confused with the unrelated C# feature of Generic classes and methods.

See Also: SerializedProperty.isArray, SerializedPropertyType.ManagedReference, SerializedPropertyType.ObjectReference
