#

#  INTRODUCTION:

#

#  This simple scriptette takes advantage of a feature built into RPGMaker's

#  built-in Audio module,  and allows you to  fade out music events  in much

#  the same way as you could background music and ambient sound effects.

#

#  Indeed, no alteration was made to the Audio class.  However, this feature

#  has always  been available  despite no method  defined for it  within the

#  Game_System class nor any map event akin to [Fade Out BGM] or the like.

#

#  To use upon an already playing ME/Music Event, run either script call:

#

#        * $game_system.me_fade(time)

#        * me_fade(time)

#          - time : duration in seconds

#

#        EX: $game_system.me_fade(0.5)

#          - Fades out the currently playing ME in 1/2 a second

#

#  This is to be executed after music events are already playing, and inten-

#  def for music events that are considered longer than normal.  Such longer

#  music events would be akin to victory music from a Final Fantasy game.

# ** Game_System

#------------------------------------------------------------------------------

#  This class handles data surrounding the system. Backround music, etc.

#  is managed here as well. Refer to "$game_system" for the instance of 

#  this class.

#==============================================================================

class Game_System

  #--------------------------------------------------------------------------

  # * Fade Out Music Effect

  #     time : fade-out time (in seconds)

  #--------------------------------------------------------------------------

  def me_fade(time)

    Audio.me_fade(time * 1000)

  end

end

#==============================================================================

# ** Interpreter

#------------------------------------------------------------------------------

#  This interpreter runs event commands. This class is used within the

#  Game_System class and the Game_Event class.

class Interpreter

  # * Fade Out Music Effect

  #     time : fade-out time (in seconds)
