         case TypeOfWeapon.M9:
         BulletVelocity = 1000;
         Ammo = 30;
         totalAmmo = 30;        
         BulletDamage = 25;
         SingleFire = true;
         break;
         
         case TypeOfWeapon.ScarH:
         BulletVelocity = 1000;
         Ammo = 100;
         totalAmmo = 100;        
         BulletDamage = 54;
         RapidFire = true;
         RateOfFire = 0.220000;
         break;         
   }                                    
 }    
 
 
 In Console there's this problem:

Assets/Scripts/WeaponShootManager.js(70,9): BCE0051: Operator '==' cannot be used with a left hand side of type 'System.Type' and a right hand side of type 'TypeOfWeapon'.
