I have t$$anonymous$$s error show up every time I try to save"NullReferenceException: Object reference not set to an instance of an object SaveSystem.fromAI (countries countries) (at Assets/Code/SaveSystem.cs:196)" Line 196 is "return new SaveSystem." I'm not sure what I am doing wrong, t$$anonymous$$s is my first time with Binary Writers. Also yes I know there are a lot of data points.

For t$$anonymous$$s you will not find an answer here. Apart from Questions regarding NullReferenceException not being allowed t$$anonymous$$s is just not solveable. You have to do t$$anonymous$$s on your own. ANY 1 or more Components or GameObjects are not being found. Good luck figuring out w$$anonymous$$ch.

What is a nullReferenceException and how do i fix it.

oh ok, could you tell me how a return new can be null?

Hey, please try to post answers as answers and comments as comments.

Example for Unity

   GameObject.Find("morocco_e").GetComponent<Control>().cavalry

throws nullref if - there is no GameObject with name "morocco_e" - there is a Gameobject wit the name but there is no Component Control on the GameObject

Sorry I’m really new to this and I’m doing this on my phone and it looks different then on my computer. Thank you, I did find the answer. I put Algeria_c when it should be Algeria_m. I think it’s weird that it put the error down as line 196 return new, and not where the line was actually null at

No problem, just try to remember it next time. Also please remember to mark correct answers as such so that others can easier find solutions to their problems.

Regarding the line: It's not weird, it is common, as from C#'s perspective, this is all one line where you create a new object. Which is - to be honest - just one of the points that shows that this current version of your code should be refactored. The longer you work with this, the more errors you will encounter with this. And god have mercy if you ever decide to change some names of any objects.

Something like:

   SICcontroller = (int)GameObject.Find("sicily_c").GetComponent<Control>().controller,
          SICCavalry = (int)GameObject.Find("sicily_c").GetComponent<Control>().cavalry,
          SICInfantry = (int)GameObject.Find("sicily_c").GetComponent<Control>().infantry,
          SICArtillery = (int)GameObject.Find("sicily_c").GetComponent<Control>().artillery,

would be way more performant and easier to maintain if it was:

    var control = GameObject.Find("sicily_c").GetComponent<Control>();
    if(control == null)
           Debug.LogError("OMG sicily has no CONTROL!!!");
    SICcontroller = (int)control.controller;
    SICCavalry = (int)control.cavalry;
    SICInfantry = (int)control.infantry;
    SICArtillery = (int)control.artillery;
