I need help...

I'm very new to coding and to unity. I'm currently doing the Creator Kit: Beginner code. Everythings worked fine until now. I'm supposed to write my first own script and to do this I need to create a new script file. They've included a template for this new script file in the Beginner Code tab on unity called "Create item Effect" When I press this I get a window to name the new script file. I name it according to the intructions they give me and press create. Then I get this error message.

NullReferenceException: Object reference not set to an instance of an object
NameWindow.OnGUI () (at Assets/Creator Kit - Beginner Code/Scripts/Editor/CreateScriptEditor.cs:178)


have no idea what it means and no idea how to fix it. I can't progress without fixing it. Any help is much appreciated

Thanks

Excellent!!! In any case, I have been working on a boilerplate response for these types of error questions:

Comments always welcome.

i neeeeed help

 

@NotSoCreative

How did you fix it? I'm encountering the same problem as well.

 

Again I suggest,

How to fix a NullReferenceException in Unity3D:

http://plbm.com/?p=221

 

Could add to that page an example of how to check what is null on a line with multiple potential null references, and that Debug.Log can be helpful. (you did ask for comments up in comment #3 )

Just as an example:

Code (csharp):

1. GameObject.FindWithTag("Player").GetComponent<CharacterStats>().AddToStrength(5);  //null ref error here, I needz helpz!!!

Comment out original, and rewrite broken up as several lines, and add checks for anything which can be null:

Code (csharp):

1. //GameObject.FindWithTag("Player").GetComponent<CharacterStats>().AddToStrength(5);  //null ref error here, I needz helpz!!!
2. GameObject playerObject = GameObject.FindWithTag("Player");
3. if (playerObject == null)
4. {
5.     Debug.Log("FindWithTag returned null for Player tag");
6. }
7. CharacterStats stats = playerObject.GetComponent<CharacterStats>();
8. if (stats == null)
9. {
10.     Debug.Log("playerObject.GetComponent<CharacterStats> returned null");
11. }
12. stats.AddToStrength(5);

 

I like it. Thanks Uncle Joe. Might just add your exact example, if you don't mind.

 

@Joe-Censored Thanks again... updated the original with a link to this new separate post:

Wrestled a bit with the WordPress formatting, which ate selective portions of the copy-pasted code, and I am still not happy with the lack of indentation on the blocks, alas.

 

Yeah no problem

 

Does wordpress let you put html spaces in for indentation?

Code (csharp):

1. &nbsp;&nbsp;&nbsp;&nbsp;This should look indented

 

Apparently not. In code blocks it just literally copies the &nbsp right in, which in some ways makes sense.

But overall I have to observe that the WordPress editing experience has steadily worsened over the past five years with every attempt to improve it. Virtually every single change since I first installed it either constantly triggers inadvertent mis-edits, makes it incredibly difficult to do simple things (join two blocks... come on!), etc.

Here is a clue to the WordPress people: make it like a "regular" text editor. Then stop. Please.
