Fade-In BGM

[arcthemonkey]

I found a script that fades in a BGM on a map, but I'd like a script that lets me fade it in from the call script command in event commands. I use fades alot during cutscenes.

It's a simple request really, just a callable script that will fade in a selected BGM over x seconds or x frames.

This request is sparce, but it really is that simple.

Anyone? :D

class Game_System
  
  def bgm_fadein(bgm, time, volume = 100)
    bgm_stop
    @bgm_targetvol = volume
    @bgm_fadestep = volume.to_f / time
    @playing_bgm = RPG::AudioFile.new(bgm, 0, 100)
    Audio.bgm_play("Audio/BGM/" + @playing_bgm.name, 0, 100)
  end
  
  def bgm_fadingin?
    return @bgm_targetvol != nil
  end
  
  def bgmfade_update
    vol = [@playing_bgm.volume + @bgm_fadestep, @bgm_targetvol].min
    @playing_bgm = RPG::AudioFile.new(@playing_bgm.name, vol, 100)
    Audio.bgm_play("Audio/BGM/" + @playing_bgm.name, @playing_bgm.volume.ceil, 100)
    unless vol.ceil < @bgm_targetvol
      @bgm_fadestep = nil
      @bgm_targetvol = nil
    end
  end
end

  
class Scene_Map
  alias old_update update
  def update
    old_update
    $game_system.bgmfade_update if $game_system.bgm_fadingin?
  end
end

Usage: $game_system.bgm_fadein(BGM_NAME, TIME, VOLUME)
Time is in frames, volume is optional (defaults to 100)
