Push down GUI everytime for loop cycles through Array

Question

Im trying to display a GUI box every time i cycle through a for function. And every time it does add a little bit to the height variable for that gui box so it goes under the previous one. Here is what i have:

     for (i = 0; i < indivSpotNo.Length; i++) {
         hgt += 30f;
         GUI.Box (new Rect (20, hgt, 30, 25), indivSpotNo [i].ToString());
     }
 }

except what is happening is the hgt variable isnt stopping for each one its just adding every time and pushing them all off screen. What else can i do that will achieve this?

I assume hgt is declared outside the method and you don't reset it?

 hgt = 0;
 for (i = 0; i < indivSpotNo.Length; i++)
 {
     hgt += 30f;
     GUI.Box (new Rect (20, hgt, 30, 25), indivSpotNo [i].ToString());
 }

thanks. that worked. I did declare it in the start function as 0. I dont see how its any different. But it worked.

Start only happens once, but (I assume yours is) OnGUI every time UI is redrawn. hgt does not get reset back to 0 between one OnGUI call and the next.
