Multiple Fogs - woratana - 01-22-2009

Multiple Fog
Version 1.0
by Woratana
Release Date: 13/05/2008


Introduction
This is one of the missing feature from RPG Maker XP.
I added feature to show more than 1 fog. (XD)

This script (Multiple Fogs) is originally scripted in XP version by me,
and it's not that hard to convert it from XP to VX.
It's a little harder to use than XP version,
because there is a fog setting window to help you setup multiple fogs in XP.

However, I tried to come up with many methods to help you setup fog's
properties here.
You can make new properties preset in the script, or set with event
command to call script, or copy the properties from showing fog.

You can choose fog image's path. Choose to clear all fog when transfer
player to other map.
And I also put 2 event commands for control fog from RMXP, 'Change Fog
Color Tone' and 'Change Fog Opacity'.

Enjoy~! (:))


Features
Version 1.0
- Show 1 fog or more at a time.
- You can change fog image's path, and choose to clear all fog when
transfer player to other map.
- Include 2 event commands 'Change Fog Color Tone' and 'Change Fog
Opacity' from RMXP.
- 3 methods to setup fog's properties. Choose the method you want~

#===============================================================
# ? [VX] ? Multiple Fogs ? ?
# * 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)

# [END] VX Multiple Fog by Woratana [woratana@hotmail.com]
#==================================================================
Instruction
>> Setup the script. There are 3 short parts to setup:
Code:
#==================================================================
    # ** MULTIPLE FOG SETUP ** SETTINGS
    
#--------------------------------------------------------------

For fog's image path, and choose to clear all fog when transfer player.
Code:
#==================================================================
    # ** MULTIPLE FOG SETUP ** FOG DEFAULT SETTING
    
#--------------------------------------------------------------

For default fog properties~
and
Code:
#==================================================================
    # ** MULTIPLE FOG SETUP ** FOG PRESET SETUP
    
#--------------------------------------------------------------

For fog properties preset.


>> The complete instruction is included the script :)

Here is the fog's properties you can set before show fog:
Code:
# $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.
If you
have use RPG Maker XP before, this image may help you understand each
properties better. :)

Show fog by call script:
Code:
$fog.show(fog_id)
fog_id is ID number you want to put
this fog in. If there is fog in this ID already, it will replace old fog.


>> Example of call script to show fog:
Code:
$fog.name = '001-Fog01'
$fog.hue = 0
$fog.tone = [0,0,0,0]
$fog.opacity = 64
$fog.blend = 1
$fog.zoom = 100
$fog.sx = 2
$fog.sy = 1

$fog.show(1)
or load fog from preset by:
Code:
$fog.load_preset(2)
$fog.show(1)
You can change its properties after load preset or
load properties from showing fog.
Code:
$fog.load_preset(2)
$fog.opacity = 40
$fog.zoom = 200
$fog.show(1)
