I followed a script from a tutorial, but I wanted to convert it to JS, and, when I do so, the GUI elements don't working properly. I'm trying to make a level bar and an experience bar, and the experience bar gets bigger the more experience the player has. However, in JS, the bar is stuck at a tiny length, and will only go backwards. It works properly if I remove the "Screen.width" and simply use a number there instead, but the bar then gets proportionally longer every level, which is undesirable.

here is the C# script: using UnityEngine; using System.Collections;

 public class Playerlevel : MonoBehaviour {
     
     private int curLevel = 1;
     private int maxLevel;
     
     public int curExp = 1;
     private int maxExp = 100;
     
     public float expBarLength;
 
     
     void Start () 
     {
     
     }
     
 
     void Update () 
     {
         AdjustCurrentExp(0);
         if(curExp >= maxExp)
         {
             curExp = 1;
             curLevel++;
             maxExp += (20 * curLevel);
         }
     }
     void OnGUI()
     {
         GUI.Box (new Rect(20, 30, expBarLength, 20), curExp + "/" + maxExp);    
         GUI.Box (new Rect(20,70,200, 20 ), "Level" + curLevel);
     }
     
     public void AdjustCurrentExp(int adjExp)
     {
         curExp += adjExp;
         
         expBarLength = (Screen.width/ 3) * (curExp / (float)maxExp);
     }
 }

and this is my JS translation:

pragma strict

 var curLevel = 1;
 var maxLevel = 10;
 
 var curExp = 1;
 var maxExp = 100;
 
 var expBarLength;

 

 

 function Update () 
 {
     AdjustCurrentExp(0);
     if(curExp >= maxExp)
     {
         
         maxExp += (20 * curLevel);
         curExp = 1;
         
         if(curLevel < maxLevel)
         {
             curLevel++;
         }
     }
 }
 function OnGUI()
 {
     GUI.Box (Rect(20, 30, expBarLength, 20), curExp + "/" + maxExp);    
     GUI.Box (Rect(20,70,200, 20 ), "Level" + curLevel);
 }
 
 public function AdjustCurrentExp(adjExp: int)
 {
     curExp += adjExp;
     expBarLength = (Screen.width/3) * (curExp / maxExp);
 }
