Adding 1 point after collison

Question

Hey,

I have an objective in my game where you have to pick up 4 times and put them in a collider. The score is kept in the upper right corner and I don't know hot to only change the number in it and not the text every time another item is added. It look like this.

 #pragma strict
 
 var item : String = "items collected: 0"; //score kept in the upper right corner
 
 function OnTriggerEnter(col : Collider)
 {
     if (col.tag == "item")
     {
         items = "items collected: 1"; //chnages the text to say 1 but I need it to simply add 1 every time an items is added
         yield WaitForSeconds(1);
         Destroy(col.gameObject);
     }
 }
 
 function OnGUI () {
     GUI.Label(Rect (10, 10, 130, 25), item );
 }

What you need to do is, add a counter.

So:

 var item : String = "items collected: "; //text
 var score : int = 0; //counter
  
 function OnTriggerEnter(col : Collider)
 {
     if (col.tag == "item")
     {
        score++; // add 1 to score
        item = "items collected: " + score;
        yield WaitForSeconds(1);
        Destroy(col.gameObject);
     }
 }

Works! Thanks, I knew it was something to do with adding a counter but I didn't know it was going to be that simple! :)
