# * Use unlimited layers of fog *

# ◦ by Woratana [woratana@hotmail.com]
# ◦ Thaiware RPG Maker Community
# ◦ Released on: 13/05/2008
# ◦ Version: 1.0
#--------------------------------------------------------------

#==================================================================
# ** HOW TO USE **
# * use event command 'Script...' for the any script line below~
#-----------------------------------------------------------------
#
#---------------------------------------------------------------
# ** SETUP FOG PROPERTIES & SHOW FOG **
# * You have to setup fog properties, before show fog~
#-------------------------------------------------------------
# * There are 3 ways to setup fog properties:
# >> Setup Fog [Custom]:
# $fog.name = 'image_name' # Image file name, must be in fog image path (setup path below).
# $fog.hue = (integer) # Fog's hue. 0 - 360, 0 for no hue.
# $fog.tone = [red, green, blue, gray] # Fog's tone color.
# $fog.opacity = (integer) # Fog's opacity. 0 - 255, you will not see fog in 0.
# $fog.blend = (0, 1, or 2) # Fog's blend type. 0 for Normal, 1 for Add, 2 for Subtract.
# $fog.zoom = (integer) # Fog's size (in %). 100 for normal size.
# $fog.sx = (+ or - integer) # Fog's horizontal move speed.
# $fog.sy = (+ or - integer) # Fog's vertical move speed.
#
# >> Setup Fog [From Preset]:
# (You can setup fog presets, in part FOG PRESET SETUP below)
# $fog.load_preset(preset_id)
#
# >> Setup Fog [From Fog that showing]:
# $fog.load_fog(fog_id)
#
#--------------------------------------------------------------
# ** SHOW FOG **
#-------------------------------------------------------------
# After setup the fog, show fog by call script:
# $fog.show(fog_id)
#
# In case you want to show new fog on same ox, oy, tone as old fog. Call Script:
# $fog.show(old_fog_id, false)
#
# * fog_id: the ID number you want to put this fog in.
# (It can be any positive number or zero)
#
# After you show fog, the fog properties you've set will replace with default setting.
# (You can setup default setting, in part FOG DEFAULT SETTING below)
#
#--------------------------------------------------------------
# ** DELETE FOG **
#-------------------------------------------------------------
# You can delete 1 or more fog(s) at a time by call script:
# $fog.delete(fog_id, fog_id, fog_id, ...)
#
#---------------------------------------------------------------
# ** OLD FOG CONTROL EVENT COMMANDS **
#-------------------------------------------------------------
# Change Fog Tone:
# $game_map.fogtone(fog_id, [red, green, blue, gray], duration)
# e.g. $game_map.fogtone(1, [100,200,-100,0], 10)

# Change Fog Opacity:
# $game_map.fogopac(fog_id, new_opacity, duration)
# e.g. $game_map.fogopac(2, 200, 10)
#
#---------------------------------------------------------------
# ** ADDITIONAL SETTINGS **
#-------------------------------------------------------------
# Change Fog Image's Path:
# $game_map.fog_path = 'image_path'
# e.g. $game_map.fog_path = 'Graphics/Pictures/'

# Turn ON/OFF [Automatically clear all fogs when transfer player]:
# $game_map.fog_reset = (true / false)
#
