SerializedProperty.managedReferenceValue

매뉴얼로 전환
public object managedReferenceValue ;

설명

The object assigned to a field with SerializeReference attribute.

For use when propertyType is SerializedPropertyType.ManagedReference.



The value object must be a type that is compatible with the base type of the managed reference field (that is, the managed reference field that the serialized property is referencing).

See Also: SerializeReference, propertyType, SerializedPropertyType.ManagedReference.
