  Perkenalan :

  event lain.
  
  Cara penggunaan :

  tulis script call sebagai berikut
  
  ----------------------------------------------------------------------
  Untuk naruh line :
  - set_arrow(pangkal,ujung)
  - set_line(pangkal,ujung)
  
  Contoh penerapan :
  - set_arrow($game_map.events[1],$game_map.events[2])
  Ngeset panah dari event id 1 ke event id 2
  
  ----------------------------------------------------------------------
