I have an issue with my on GUI function when I compile I get this error and I don’t see what I am doing wrong.

Could someone please help me? Am I missing something or not programming it right?

function OnGUI()

{

if(conActive)

{

	for(t = 0; t < game.teamPlayerList.Count; t++)

	{

		TeamFPSPlayerNode = game.teamPlayerList[t] as TeamFPSPlayerNode;

	}	

  }

}

Let’s look at your first example:

TeamFPSPlayerNode = game.teamPlayerList[t] as TeamFPSPlayerNode;

I’m assuming here that “TeamFPSPlayerNode” is a type – that it’s a class you’ve built, somewhere? Some people helpfully suggested that you should declare a variable and give it a name, like so:

TeamFPSPlayerNode go = game.teamPlayerList[t] as TeamFPSPlayerNode;

But this has another problem: UnityScript doesn’t declare variables in the same way that most “C family” languages do.

//C#
int x;

//UnityScript
var x : int;

You don’t actually have to provide a type, in UnityScript, if the compiler can infer which type you want:

//these two lines do the same thing
var x : int = 2;
var x = 2; //the compiler can tell up front that you want an integer

If you want to declare a variable and assign it later? Then you’ll need to specify a type. It’s possible to get into some interesting shenanigans, there, anyway. It’s always safer to specify a type, but it’s nice to know sometimes that you don’t always have to.

(C# has a similar feature using var, actually, but I notice a lot of people get confused by it.)

So, getting back to your script, we need to change the syntax used when declaring your variable:

var go = game.teamPlayerList[t] as TeamFPSPlayerNode;

Well it looks like all you are doing in the for loop is defining some object, so you need to have a variable in there like “go” to be the variable. You aren’t doing anything with this variable, so I assume after you get this fixed you’ll go on to doing something with that go variable.

function OnGUI()
{
if(conActive)
{
for(t = 0; t < game.teamPlayerList.Count; t++)
{
TeamFPSPlayerNode go = game.teamPlayerList[t] as TeamFPSPlayerNode;
}
}
}
