  4. Introduction
  5.  
  6.                               This is a c1 version of throwing-knives, There are some new features added to it.
  7.                               Now aiming completely depends upon player's crosshair. Players can throw knives vertically upwards and
  8.                               downwards. Enhances gameplay as well.
  9.  
  10.  
  11.                             NOTE: • Uses PlayerAttachedObject slot '0','1','2','3'.
  12.                                   • "Do not" set the distance according to you for better response from the include.
  13.
