# * Features
#-------------------------------------------------------------------------------
# - Realistic Light
# - Light does not pass over walls, blocks and roofs
# - Static Light Sources
# - Dynamic Light Sources (like a player's lantern)
# - Multiple effects
# - Easy to use (comments)
#
#-------------------------------------------------------------------------------
# * WARNING - Performance
#-------------------------------------------------------------------------------
# This script may be too heavy to old processors! The Awesome Light Effects was
# tested on a Core 2 Duo E4500 and on a Core i5, without any lag. However,
# there's other factors that may influence the script performance:
#
# 1. Map size
# This script searches surfaces on the map, in order to cut the light pictures.
# In a huge map, the number of surfaces may increase a lot, affecting the
# DYNAMIC LIGHT SOURCE only. Map size does not influence the static sources.
#
# 2. Number of effects
# This script draws the effects on the screen, but before drawing, it checks 
# if the effect is out of screen (in this case, the script will skip the 
# light drawing). Too much effects may cause lag, but this is just a prevision.
#
# 3. Effect's picture size
# The picture size of the DYNAMIC LIGHT SOURCE influences directly on your 
# game's performace. The bigger is the picture, the slower it will be to
# draw it dynamically. The recommended maximum size is 200x200 pixels
# 
#-------------------------------------------------------------------------------
# * WARNING - Light pictures
#-------------------------------------------------------------------------------
# In order to run this script correctly, the light pictures MUST obey the
# following conditions:
# 1. The picture's size MUST be multiple of 2. Example: 150x150
# 2. The picture's width MUST be equal to it's height. Example: 156x156
# 3. The picture's colors MUST be inverted! This is necessary because
#    the script inverts the colors to draw the effect. The black color
#    will be transparent!
#
#-------------------------------------------------------------------------------
# * Instructions - 1. Setup your effects!
#-------------------------------------------------------------------------------
# In order to setup your static effects, go to the setup part and define your
# effects inside the Effects hash. Do as the following mode:
#
# X => [picture,opacity,variation,cut],   <= Remember to put a comma here!
#
# Where:
# picture => Picture's name, inside the Graphics/Lights folder;
# opacity => Effect's opacity;
# variation => Effect's opacity variation;
# cut => Put true to cut the effect or false to don't;
# X => The effect's ID, it will be used on events. 
#
# Check the default effects to understand how they work.
#
#-------------------------------------------------------------------------------
# * Instructions - 2. Use your effects!
#-------------------------------------------------------------------------------
# In order to use a effect, put the following comment on a event:
# 
# [light x]
#
# Where x must be the Effect's ID.
# 
#-------------------------------------------------------------------------------
# * Instructions - 3. Use an awesome lantern!
#-------------------------------------------------------------------------------
# The dynamic light source (lantern) is initialized invisible by default. 
# You may call the following commands:
# 
# l = $game_map.lantern
# Gets the lantern into a variable
 
# l.set_graphic(i)
# Sets the lantern's graphic to i, where i must be the picture's file name on 
# Graphics/Lights folder.
#
# l.set_multiple_graphics(h)
# Sets the lantern's graphics to h, where h must be a hash with the following
# structure:
#
# h = {2=>"ld",4=>"ll",6=>"lr",8=>"lu"}
# 
# Where: 
# "ld" is the name of the picture when the lantern's owner is looking down;
# "ll" is the name of the picture when the lantern's owner is looking left;
# "lr" is the name of the picture when the lantern's owner is looking right;
# "lu" is the name of the picture when the lantern's owner is looking up.
#
# l.change_owner(char)
# Sets the lantern's owner to char. Char must be ONE of the following commands:
# $game_player           <= The player itself;
# self_event             <= The event where the command was called;
# $game_map.events[x]    <= The event ID x.
#
# l.set_opacity(o,p)
# Sets the lantern's opacity, where:
# o is the opacity itself;
# p is the opacity variation.
#
# l.show
# After setting the lantern with the commands above, you may set it to visible
# using this command.
#
# l.hide
# Use this command to set the lantern as invisible.
#
#-------------------------------------------------------------------------------
# * Instructions - 4. Use the effect's surface!
#-------------------------------------------------------------------------------
# The Awesome Light Effects draws the effects on a surface. In order to make
# the effects visible, the effect's surface MUST be visible. The Effect's 
# Surface is initialized with it's opacity set to zero. You can call the
# following commands:
#
# s = $game_map.effect_surface
# Gets the Effect's Surface into a variable
#
# s.set_color(r,g,b)
# Changes the Effect's Surface color instantly, where:
# r => red level;
# g => green level;
# b => blue level;
#
# s.set_alpha(a)
# Changes the Effect's Surface opacity instantly to a.
#
# s.change_color(time,r,g,b)
# Changes the Effect's Surface color ONLY in a certain time, where:
# time => The change's time (frames);
# r => red level;
# g => green level;
# b => blue level;
#
# s.change_color(time,r,g,b,a)
# Changes the Effect's Surface color and it's opacity in a certain time, where:
# time => The change's time (frames);
# r => red level;
# g => green level;
# b => blue level;
# a => opacity
#
# s.change_alpha(time,a)
# Changes the Effect's Surface opacity in a certain time, where:
# time => The change's time (frames);
# a => opacity
#
#-------------------------------------------------------------------------------
# * Instructions - 5. Use the effect's surface with Tone command!
#-------------------------------------------------------------------------------
# You can access the Effect's Surface with the "Screen Tone" command. In order
# to turn this feature on, set the "Surface_UE" constant to true.
#
# If you decided to use this feature, please note some details:
# 1. The colors values must be between 0 and 255;
# 2. The time is in frames;
# 3. The "gray" value will be sent as the opacity value
#
#-------------------------------------------------------------------------------
# * Instructions - 6. Setup your Tileset Tags!
#-------------------------------------------------------------------------------
# In order to cut the effect's picture correctly, there's 3 types of behavior
# for a tile: wall, block and roof. Walls will make shadows as real walls, 
# blocks as blocks and roofs as roofs. So, the tileset tags MUST be configured.
# Check the demo to understand how this system works. If the tilesets aren't 
# configured correctly, the script won't cut the effects correctly.
#

# * Features


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


# - Realistic Light


# - Light does not pass over walls, blocks and roofs


# - Static Light Sources


# - Dynamic Light Sources (like a player's lantern)


# - Multiple effects


# - Easy to use (comments)


#


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


# * WARNING - Performance


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


# This script may be too heavy to old processors! The Awesome Light Effects was


# tested on a Core 2 Duo E4500 and on a Core i5, without any lag. However,


# there's other factors that may influence the script performance:


#


# 1. Map size


# This script searches surfaces on the map, in order to cut the light pictures.


# In a huge map, the number of surfaces may increase a lot, affecting the


# DYNAMIC LIGHT SOURCE only. Map size does not influence the static sources.


#


# 2. Number of effects


# This script draws the effects on the screen, but before drawing, it checks 


# if the effect is out of screen (in this case, the script will skip the 


# light drawing). Too much effects may cause lag, but this is just a prevision.


#


# 3. Effect's picture size


# The picture size of the DYNAMIC LIGHT SOURCE influences directly on your 


# game's performace. The bigger is the picture, the slower it will be to


# draw it dynamically. The recommended maximum size is 200x200 pixels


# 


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


# * WARNING - Light pictures


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


# In order to run this script correctly, the light pictures MUST obey the


# following conditions:


# 1. The picture's size MUST be multiple of 2. Example: 150x150


# 2. The picture's width MUST be equal to it's height. Example: 156x156


# 3. The picture's colors MUST be inverted! This is necessary because


#    the script inverts the colors to draw the effect. The black color


#    will be transparent!


#


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


# * Instructions - 1. Setup your effects!


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


# In order to setup your static effects, go to the setup part and define your


# effects inside the Effects hash. Do as the following mode:


#


# X => [picture,opacity,variation,cut],   <= Remember to put a comma here!


#


# Where:


# picture => Picture's name, inside the Graphics/Lights folder;


# opacity => Effect's opacity;


# variation => Effect's opacity variation;


# cut => Put true to cut the effect or false to don't;


# X => The effect's ID, it will be used on events. 


#


# Check the default effects to understand how they work.


#


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


# * Instructions - 2. Use your effects!


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


# In order to use a effect, put the following comment on a event:


# 


# [light x]


#


# Where x must be the Effect's ID.


# 


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


# * Instructions - 3. Use an awesome lantern!


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


# The dynamic light source (lantern) is initialized invisible by default. 


# You may call the following commands:


# 


# l = $game_map.lantern


# Gets the lantern into a variable


 


# l.set_graphic(i)


# Sets the lantern's graphic to i, where i must be the picture's file name on 


# Graphics/Lights folder.


#


# l.set_multiple_graphics(h)


# Sets the lantern's graphics to h, where h must be a hash with the following


# structure:


#


# h = {2=>"ld",4=>"ll",6=>"lr",8=>"lu"}


# 


# Where: 


# "ld" is the name of the picture when the lantern's owner is looking down;


# "ll" is the name of the picture when the lantern's owner is looking left;


# "lr" is the name of the picture when the lantern's owner is looking right;


# "lu" is the name of the picture when the lantern's owner is looking up.


#


# l.change_owner(char)


# Sets the lantern's owner to char. Char must be ONE of the following commands:


# $game_player           <= The player itself;


# self_event             <= The event where the command was called;


# $game_map.events[x]    <= The event ID x.


#


# l.set_opacity(o,p)


# Sets the lantern's opacity, where:


# o is the opacity itself;


# p is the opacity variation.


#


# l.show


# After setting the lantern with the commands above, you may set it to visible


# using this command.


#


# l.hide


# Use this command to set the lantern as invisible.


#


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


# * Instructions - 4. Use the effect's surface!


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


# The Awesome Light Effects draws the effects on a surface. In order to make


# the effects visible, the effect's surface MUST be visible. The Effect's 


# Surface is initialized with it's opacity set to zero. You can call the


# following commands:


#


# s = $game_map.effect_surface


# Gets the Effect's Surface into a variable


#


# s.set_color(r,g,b)


# Changes the Effect's Surface color instantly, where:


# r => red level;


# g => green level;


# b => blue level;


#


# s.set_alpha(a)


# Changes the Effect's Surface opacity instantly to a.


#


# s.change_color(time,r,g,b)


# Changes the Effect's Surface color ONLY in a certain time, where:


# time => The change's time (frames);


# r => red level;


# g => green level;


# b => blue level;


#


# s.change_color(time,r,g,b,a)


# Changes the Effect's Surface color and it's opacity in a certain time, where:


# time => The change's time (frames);


# r => red level;


# g => green level;


# b => blue level;


# a => opacity


#


# s.change_alpha(time,a)


# Changes the Effect's Surface opacity in a certain time, where:


# time => The change's time (frames);


# a => opacity


#


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


# * Instructions - 5. Use the effect's surface with Tone command!


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


# You can access the Effect's Surface with the "Screen Tone" command. In order


# to turn this feature on, set the "Surface_UE" constant to true.


#


# If you decided to use this feature, please note some details:


# 1. The colors values must be between 0 and 255;


# 2. The time is in frames;


# 3. The "gray" value will be sent as the opacity value


#


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


# * Instructions - 6. Setup your Tileset Tags!


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


# In order to cut the effect's picture correctly, there's 3 types of behavior


# for a tile: wall, block and roof. Walls will make shadows as real walls, 


# blocks as blocks and roofs as roofs. So, the tileset tags MUST be configured.


# Check the demo to understand how this system works. If the tilesets aren't 


# configured correctly, the script won't cut the effects correctly.


#
