problems with putting objects in al list

when I try to put this.object in the MyTeam List from EnemieAI it doesn't do that, while when I put it in the Other team list it works just fine.

this is these are the errors i got:

NullReferenceException: Object reference not set to an instance of an object
Enemie.Start () (at Assets/scripts/Objects/Enemie.cs:37)

NullReferenceException: Object reference not set to an instance of an object
Enemie.Start () (at Assets/scripts/Objects/Enemie.cs:30)

NullReferenceException: Object reference not set to an instance of an object
EnemieAI.CalculateInputs () (at Assets/scripts/AI/EnemieAI.cs:28)
EnemieAI.MoveMembers () (at Assets/scripts/AI/EnemieAI.cs:72)
AIManager.Update () (at Assets/scripts/AI/AIManager.cs:36)

here are the scripts:

Is the object containing the AIManager component missing a reference to the

Code (csharp):

1. public EnemieAI Blue;

object in the editor?

 

What do you mean?

 

It looks like your line numbers have shifted when you posted your code. I'd ask for the specific lines with the errors, but you shouldn't need people's help with this. The way you tackle null reference errors is the exact same process every time. First you go to the first null reference error, then go to the line it occurs and count the reference variables on that line. If there is only one reference type used on that line, then you know what variable is null. Then just make it not null before trying to use it. If there is more than one reference type variable on that line, then add debugging beforehand to figure out which one it is, something like below. Once you figure out which one is null, again make it not null.

Code (csharp):

1. if (suspiciousVariable == null)
2. {
3.     Debug.Log("suspiciousVariable is the one that is null");
4. }

 

The thing is, both of these lines of code are basically identical, but the he one on the top doesn't work while the one on the bottom does:

Enemie.cs

Code (csharp):

1.  
2.             Manager.Red.MyTeam.Add(this.gameObject);
3.             Manager.Blue.OtherTeam.Add(this.gameObject);
4.  

both of the lists I try to put "this.gameObject" in are also created in the same way:

EnemieAI.cs

Code (csharp):

1.  
2.             public List<GameObject> MyTeam;
3.             public List<GameObject> OtherTeam;
4.  

 

What makes you think the second line works? When you hit a null ref exception adding to MyTeam in Start, the rest of Start won't be run, so you don't even get to that next line. I don't see anywhere you are initializing any of your lists in your EnemieAI class, so MyTeam, OtherTeam, etc, are all null when you are trying to add to them.

 

What I'm meaning is that when you have a public object/field, you should be able to see said object/field within the script component attached to the object in the inspector. Are you missing a reference to the object giving you the errors? Is the EnemieAI reference empty in the inspector?
