I'm having trouble getting my score to display through GUI.Label

Question

When I run the following script:

static var SCORE : int = 0;

function OnGUI () { GUI.Label (Rect (10, 10, 100, 20), SCORE); }

I get this error: Assets/MeMadeStuff/ScoreBoard.js(5,19): BCE0023: No appropriate version of 'UnityEngine.GUI.Label' for the argument list '(UnityEngine.Rect, int)' was found.

And my score of 0 does not display.

I do not understand why I cannot display SCORE, when I change the script to read:

static var SCORE : int = 0;

function OnGUI () { GUI.Label (Rect (10, 10, 100, 20), "hello"); }

The script properly displays "hello"

What am I doing wrong that is preventing me from being able to have my static var SCORE displayed on my screen?

If you look at the docs for GUI.Label, you see this:

static function Label (position : Rect, text : string) : void
static function Label (position : Rect, image : Texture) : void
static function Label (position : Rect, content : GUIContent) : void

(Plus another version of the same with a GUIStyle parameter.) As you can see, you can only display a string, a texture, or GUIContent. In order to display an int, you have to convert it to a string, such as with ToString().

Thanks for the tip. So I'm now trying to convert my integer SCORE to a string. I read here http://answers.unity3d.com/questions/9679/score-system-for-destroying-objects , that you do that by using the following command:

SCORE.ToString();

but when I do that, I get the error:

Assets/MeMadeStuff/ScoreBoard.js(8,16): BCE0022: Cannot convert 'int' to 'String'.

My int SCORE is set to 0, so shouldn't this have no problem changing the integer 0 to the string 0? I've got to be missing something here. . .

@Ecnalyr: Are you using "`function OnGUI () { GUI.Label (Rect (10, 10, 100, 20), SCORE.ToString()); }`" ?

I thought I was using just that, but when I deleted mine and pasted yours, it worked. Maybe there was a weird typo I wasn't aware of. Thank you sincerely.

I did a label with ints in it without having to use toString() before. Maybe it's because for the text parameter of Label i put something like "int : " + myInt

if you do string + int, it implicitly casts the int to a string to do the concatenation - if you only use an int, you need to do it yourself with ToString()
