Why Unity Automatically Serialize Scripts?

Hi, sometimes I need to disable save-load system, but Unity automatically load last values and assign them to serializable variables. How can I disable it?

 

Almost no information to go on here, but perhaps look up the NonSerializable attribute, if that is your issue.

 

I have a class like that:

Code (CSharp):

1. [System.Serializable]
2. public class SaveData {
3.     public int row;
4.     public int  col;
5. }

I dont have any other code for save these values, but when I change them in game, Unity save them automatically.
