set type to instantiate in static function

Question

Hi there, i'd like to make a script i can call from anywhere without the need of having the script attached to a game object in the current scene to instantiate a GameObject.

I have the following code in my script:

 static var console:GameObject;
 static var consoleType:GameObject;
 
 static function Write(text:String)
 {
     if(!console)
     {
         console=Instantiate (consoleType, Vector3(0,0,0), Quaternion.identity);
     }
 }

I'd like to know how to set the variable "consoleType". If the script is attached to a game object, I can set the variable by dragging a prefab into corresponding space in the inspector but how do I do this if it's not attached to a game object?

I believe you can also do this:

 console = Instantiate(Resources.Load("NameOfConsole")) as GameObject;

thi sis the correct answer to my problem. I'll give save's DontDestroyOnLoad idea a try, though. seems to be better for a console.

Yes, but a console (if it is what I think it is), it'll be comfortable to be able to store the string over levels. So if you want to post something to the console, it'll still be visible after loading next level using a manager / DontDestroyOnLoad on the script for the console. Usually using a console isn't just about giving commands, it's nice to have for feedback from the game at runtime.

So something like (combining @tayl0r's fine answer) this:

 if (!GameObject.Find("NameOfConsole")) {
     console = Instantiate(Resources.Load("NameOfConsole", GameObject));
     console.name = "NameOfConsole";
 }

and on the console:

 function Awake () {
     DontDestroyOnLoad (transform.gameObject);
 }

Regarding the issue in your other comment, I think you somehow have mixed up what is local for the GameObject and what is static. It's hard to tell when we don't see your code, but you'd have to treat static variables and functions with the rules it comes with. Refer to it as TheScript.theVariable. You can't reference from a static function to a local variable, you'd have to cast it forward from the local to the static:

 static var aStaticTransform : Transform;
 var aTransform : Transform;
 function Start () {
     ThisScript.aStaticTransform = aTransform;
 }
