Adding a bar that reset for each level

Question

Ok I have with the help of those below managed to get my script cleaned up and an experience bar working but now at the last lvl (10) when you max your exp it still allows the experience to continue run the bar over the length over the length it should be I cant seem to get it to stop.

Here is the code.

 using UnityEngine;
 using System.Collections;
 
 public class PlayerStats : MonoBehaviour 
 {
     public int curExperience = 0;//Our current experience.
     public int curLevel = 1;//Our current level.
     playerHealth player;//Reference to the player health script and assigned to player so we can modify parts.
     ShiledHealth  shiledH;//Reference to the shiled health script and assigned to shiledH so we can modify parts.
     
     Rect box = new Rect(10, 50, 160, 17);// Starte Cordonates
     public Texture2D background; // Texture for the background of your health bar
     public Texture2D foreground; // Texture for the forground of your health bar
     
 
     public int[] healthlvl = new int [10] {400, 900, 1400, 2100, 2800, 3600, 4500, 5400, 6500, 7600};
     public int[] shieldlvl = new int [10] {400, 900, 1400, 2100, 2800, 3600, 4500, 5400, 6500, 7600};
     public int[] lvl = new int[10] {100, 300, 500, 700, 900, 1100, 1300, 1500, 1700, 1900};
     
     void Start () 
     {
         player = GameObject.Find ("Player").GetComponent<playerHealth>();//This searches for the Gameobject you tell it to find the health script.
         shiledH = GameObject.Find ("Player").GetComponent<ShiledHealth>();//This searches for the Gameobject you tell it to find the shield health script.
     }
     
     // Update is called once per frame
     void Update () 
     {
         
     if(curLevel < lvl.Length && curExperience >= lvl[curLevel-1])
         {
                     curLevel += 1;
                      player.playerMaxHealth += healthlvl[curLevel-1];
                   shiledH.shieldMaxHealth += shieldlvl[curLevel-1];
                   curExperience = 0;
         }
     }
     void OnGUI()
     {
             
         GUI.DrawTexture(new Rect(148, 38, box.width, box.height), background, ScaleMode.StretchToFill); 
         GUI.DrawTexture(new Rect(148, 38, box.width*curExperience/lvl[curLevel-1], box.height), foreground, ScaleMode.StretchToFill); 
         
         
     
     }
 }

This was in the script example I gave you in your other question. This makes the bar fill depending on percentages of max health and background length. Again, I've attached a sample image for you to use with this. You would need to add your current level / health variables obviously. alt text

 using UnityEngine;
 using System.Collections;
  
 public class Example : MonoBehaviour
 {
     public Texture2D bar;
     Rect bgRect;
     Rect barRect;
     Rect labelRect;
     int exp = 0;
     public int maxExp = 1000;
  
     void Awake()
     {
        bgRect = new Rect(32, 32, 512, 24);
        barRect = new Rect(34, 34, 0, 20);
        labelRect = new Rect(32, 64, 128, 24);
     }  
  
     void Update()
     {
        if(exp > 0)
          barRect.width = exp * bgRect.width / maxExp;
  
        //TEST
        if(exp < maxExp)
        {
          if(Input.GetKey (KeyCode.KeypadPlus))
           exp += 10;
        }
     }
     void OnGUI()
     {
        GUI.Box (bgRect, GUIContent.none);    
        GUI.DrawTexture(barRect, bar);
        GUI.Label(labelRect, exp.ToString());
     }
 }

btw: I believe that you can get the screen width with

 Screen.width

If you know the proper length of the bar (not sure how that changes depending on screen resolution) you should be able to calculate how to increase the bars length and for how much xp.

Example:

 int window_with = 640; //in this case you'd probably need to get this value from the resolution assuming that the resolution can be changed
 //maximum bar size
 double bar_width = 640*0.8;//so the bar would fill up 80% of the width and it's size would be 512
 public int lvl_2 = 900;
 double percet = lvl_2/bar_width; //how much xp is needed to fill up 1% of the bar

So all you have to do is to check the players XP and increase the bars size.

enter code heredouble barSize = curExperience/percet; //which is the size of the bar on the screen

Additional you might improve the code if you would define the xp/hp/etc. for each level in a list/array (or even another object)

quick example with array/list:

 int curLevel = 1;
 int[] lvl_xp = {400,900,1400,2100,2800}//each entry represents 1 level
 int[] lvl_hp = {10,20,30,40,50}
 
 //so you could do all the checks/level ups via
 
 if(curExperience >= lvl_xp[curLevel]){
      player.playerMaxHealth += lvl_hp[curLevel];
      curLevel += 1;
      //...
 }

This most probably isn't the best or pretiest way , but it might help or at last I hope so :)

You can calculate you current progression with something like :

float percent = (float)curExperience / (float)lvl[curLevel];

Then, calcul the size of the second texture with :

int barSize = (int)Mathf.Lerp(0f, box.width, percent);

Finally, your second texture draw will be :

GUI.DrawTexture(new Rect(148, 38, barSize, box.height), foreground, ScaleMode.StretchToFill);
