List is not null with [SerializeField]
Hi there,
I just had a very weird behaviour with one of my Lists. I need to know if one of my lists is null. So I test that with
void Start()
{
Debug.Log(myList == null);
}
When I define my variable like this:
[SerializeField] List<MyObjects> myList = null;
The console output is: False
But when I define my variale like this:
List<MyObjects> myList = null;
The console output is: True
That's really dangerous and confusing, any idea why that is the case?
When you go to the editor, those objects which have attached your script modify that list and convert it to an empty list. Not null, list of size 0.
As @Bunny83 pointed out , Serialization does not support null values.
HideInInspector does not change the serialization behaviour. As long as the variable is serialized, it will contain a list instance. Custom serializable classes as well as Lists or arrays do not support null values as they are serialized inline by value. Have a look at script serialization
I didn't know that, thanks for the clarification!
Since you closed the question i took the liberty of accepting this answer.
