     GUI.Button(new Rect(145, 35, healthBarLength, 24), curHealth + "/" + maxHealth);
     }
     
     public void AddjustCurrentHealth(int adj)
     {
     curHealth += adj;
     
     if(curHealth < 0)
         curHealth = 0;
         
     if(curHealth > maxHealth)
         curHealth = maxHealth;
         
     if(maxHealth < 1)
         maxHealth = 1;
         
     healthBarLength = (Screen.width / 6) * (curHealth / (float)maxHealth);
     }
 }
