The SetNullState method is used to set the null state of a serialized property. This method allows you to explicitly define whether the property should be considered as null or not. This is particularly useful when dealing with nullable types or when you need to reset the state of a property to null.
To use the SetNullState method, call it on an instance of SerializedProperty and pass a boolean value indicating the desired null state. Passing true will set the property to a null state, while false will set it to a non-null state.
// Example of using SetNullState SerializedProperty property = new SerializedProperty(); // Set the property to a null state property.SetNullState(true); // Check if the property is null bool isNull = property.IsNull; // Returns true // Set the property to a non-null state property.SetNullState(false); // Check if the property is null isNull = property.IsNull; // Returns false
