#============================================================================# XP Style Fog# v1.0 by Shaz#----------------------------------------------------------------------------# This is a simple port of XP's fog system.#----------------------------------------------------------------------------# To Install:# Copy and paste into a new script slot in Materials.  This script aliases# existing methods, so can go below all other custom scripts.#----------------------------------------------------------------------------# To Use:# Create a Fogs folder inside your game's Graphics folder, and paste your# fog png files there## There are two ways of adding fog to a map:# 1. Set it in map notes - fog will be loaded when the map is loaded (all values #    must be present)#    <fog name hue opacity blend_type zoom speed-x speed-y># 2. via a Call Script command - fog will be added when the command is run#    Call Script: $game_map.add_fog(name, hue, opacity, blend_type, zoom, #      speed_x, speed_y)## Use the following two commands to make changes to fog# Call Script: $game_map.start_fog_tone_change(red, green, blue, gray, duration)# Call Script: $game_map.start_fog_opacity_change(opacity, duration)## You can also modify the $game_map fog attr_accessors individually via # Call Script commands.#----------------------------------------------------------------------------# Terms:# Use in free or commercial games# Credit Shaz#============================================================================module Cache  #--------------------------------------------------------------------------  # * Get Fog  #--------------------------------------------------------------------------  def self.fog(filename, hue)    load_bitmap("Graphics/Fogs/", filename, hue)  endendclass Game_Map  #--------------------------------------------------------------------------  # * Public Instance Variables  #--------------------------------------------------------------------------  attr_accessor :fog_name                 # fog file name  attr_accessor :fog_hue                  # fog hue  attr_accessor :fog_opacity              # fog opacity level  attr_accessor :fog_blend_type           # fog blending method  attr_accessor :fog_zoom                 # fog zoom rate  attr_accessor :fog_sx                   # fog sx  attr_accessor :fog_sy                   # fog sy  attr_reader   :fog_ox                   # fog x-coordinate starting point  attr_reader   :fog_oy                   # fog y-coordinate starting point  attr_reader   :fog_tone                 # fog color tone  #--------------------------------------------------------------------------  # * Setup  #--------------------------------------------------------------------------  alias shaz_fog_game_map_setup setup  def setup(map_id)    shaz_fog_game_map_setup(map_id)    setup_fog    setup_notes  end  #--------------------------------------------------------------------------  # * Setup Notes  #--------------------------------------------------------------------------  def setup_notes    @map.note.split(/[\r\n+]/).each do |line|      case line      when /<fog\s*(\w+)\s*(\d+)\s*(\d+)\s*(\d+)\s*(\d+)\s*(\d+)\s*(\d+)>/i        @fog_name = $1        @fog_hue = $2.to_i        @fog_opacity = $3.to_i        @fog_blend_type = $4.to_i # 0-normal, 1-add, 2-sub        @fog_zoom = $5.to_i        @fog_sx = $6.to_i        @fog_sy = $7.to_i      end    end  end  #--------------------------------------------------------------------------  # * Setup Fog  #--------------------------------------------------------------------------  def setup_fog    @fog_name = ""    @fog_hue = 0    @fog_opacity = 0    @fog_blend_type = 0    @fog_zoom = 0    @fog_sx = 0    @fog_sy = 0    @fog_ox = 0    @fog_oy = 0    @fog_tone = Tone.new(0, 0, 0, 0)    @fog_tone_target = Tone.new(0, 0, 0, 0)    @fog_tone_duration = 0    @fog_opacity_duration = 0    @fog_opacity_target = 0  end  #--------------------------------------------------------------------------  # * Add Fog  #--------------------------------------------------------------------------  def add_fog(name, hue = 90, opacity = 64, blend_type = 0, zoom = 200, sx = 0, sy = 0)    @fog_name = name    @fog_hue = hue    @fog_opacity = opacity    @fog_blend_type = blend_type    @fog_zoom = zoom    @fog_sx = sx    @fog_sy = sy  end  #--------------------------------------------------------------------------  # * Start Changing Fog Color Tone  #     R, G, B, Gray : tone  #     duration      : time  #--------------------------------------------------------------------------  def start_fog_tone_change(red, green, blue, gray, duration)    @fog_tone_target = Tone.new(red, green, blue, gray)    @fog_tone_duration = duration    if @fog_tone_duration == 0      @fog_tone = @fog_tone_target.clone    end  end  #--------------------------------------------------------------------------  # * Start Changing Fog Opacity Level  #     opacity   : opacity level  #     duration  : time  #--------------------------------------------------------------------------  def start_fog_opacity_change(opacity, duration)    @fog_opacity_target = opacity * 1.0    @fog_opacity_duration = duration    if @fog_opacity_duration == 0      @fog_opacity = @fog_opacity_target    end  end  #--------------------------------------------------------------------------  # * Update Fog  #--------------------------------------------------------------------------  def update_fog    @fog_ox -= @fog_sx / 8.0    @fog_oy -= @fog_sy / 8.0    # Manage change in fog color tone    if @fog_tone_duration >= 1      d = @fog_tone_duration      target = @fog_tone_target      @fog_tone.red = (@fog_tone.red * (d -
