#  Enables ability to "sound" footsteps when walking over specific tiles
#==============================================================================
# Usage:
=begin
 
  Simple, place the audio files in your SE directory, and try the game.
 
  There are some known bugs in this, if anyone has any fixes just let me know:)
 
  To add custom sounds for custom tiles you can do for example:
 
  FOOTSTEP_WOOD = [15] # The tilenumber ID that you get with debug_tileid function
  FOOTSTEP_WOOD_FILE = "Audio/SE/stepwood" # The filename for the sound
 
  then add underneath the # Insert custom sounds here line:
 
  footstep_check ( FOOTSTEP_WOOD, FOOTSTEP_WOOD_FILE, 0 )
 
  The last number in that function stands for the layer, since the wood tile i
  selected is on the ground layer, it's layer is 0.
 
  (NOTE)
  There is a problem that when you go on carpet it makes dirt and snow sounds,
  i currently can't find a way to fix this, so, the best thing to do is to call
  the command $game_player.footsteps_enabled = false.
 
  To enable footsteps while stopping the carpet and tables from making the snow
  and dirt sounds, there's an uneasy solution of placing a touch event which
  calls $game_player.footsteps_enabled = false.
 
  Sorry about this inconvenience.
