Why do I have to call ToString() when fetching a String from another script?

Question

Hello,

I've noticed that when I call a string from another script to set it in the current script, I have to convert it ToString even if it is already a string... Why is that?

I'd like to know, to be able to foresee future problems it could cause.

example code

private var xObject : GameObject; private var yScript : yScript;

var nString = "01";

function Start(){
   xObject = GameObject.Find("xObject");
   yScript = GameController.GetComponent ("yScript");
}

function Update(){
   nString = yScript.ynString.ToString();
}

So in t$$anonymous$$s script, why do I have to call ToString() when ynString is already a string?

Simple like to an information page, or what to look up exactly would suffice.

Thank You.

You do not, in fact, have to use ToString if the variable is already a string. I guess you're not getting a string, but an integer or somet$$anonymous$$ng. It's impossible to say without knowing what you're doing. You should post working code, and all of it that's relevant, not just one script (w$$anonymous$$ch depends on another script).

FYI, don't use strings in GetComponent unless it's really necessary. Just do GetComponent(yScript), w$$anonymous$$ch is faster and gives you compile-time errors instead of run-time errors.

try declaring sString as a string. Im assuming the compiler t$$anonymous$$nks its a object and not a string.

 var nString : String = "01";
