SCREEN SIZE for RMXP
Version: 1.0

The Re-Envisioned Game Set

Introduction
I've been tinkering with manipulating the size of the available gaming area for RPGMaker XP games. This is essentially the barebones system that allows me to do so, all without the need of a DLL outside Win32 manipulations.

For this, I have combined a collection of scripts known as 'Hidden Class' rewrites into one, and added a few touches to allow them to go beyond their original limitations.

However, it is not a complete system. You will need a Tilemap script in order to fill the space left vacant when increasing the screen size beyond the default 640x480 size, or to accommodate any map when the game screen is smaller than normal.

The Game.Exe's Fullscreen mode reverts to a fixed 640x480 resolution so the [ALT]+[ENTER] key combination is disabled. Fullscreen mode is literally disabled by intent with this setup.

#  INTRODUCTION:

#  =============

#  I've been tinkering with manipulating the size of the available gaming area

#  for RPGMaker XP games. This is essentially the barebones system that allows

#  me to do so, all without the need of a DLL outside Win32 manipulations.

#

#  For this,  I have combined  a collection of scripts known as 'Hidden Class'

#  rewrites into one, and added a few touches to allow them to go beyond their

#  original limitations.

#

#  However,  it is not  a complete system.  You will need  a Tilemap script in

#  order to fill the space left vacant  when increasing the screen size beyond

#  the default 640x480 size, or to accommodate any map when the game screen is

#  smaller than normal.

#

#  ALERT: The Game.Exe's Fullscreen mode reverts to a fixed 640x480 resolution

#         so the [ALT]+[ENTER] key combination is disabled. Fullscreen mode is

#         literally disabled by intent with this setup.

#

#

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

#

#  INSTALLATION:

#  =============

#  This script requires methods from the RMXP SDK v 2.3 or higher. Ergo, this

#  script needs to be placed below the RMXP SDK,  or any collection of needed

#  SDK classes thereof.

#

#  RMXP SDK Methods manipulated:

#  * Spriteset_Map.init_viewports * Spriteset_Battle.init_viewport

#

#

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

#

#  INSTRUCTIONS:

#  =============

#  I would hope this is clear.  It is mostly plug-and-play, only requiring you

#  to set some configurable values within the ScrnSize module  at the very top

#  of the actual system code.  And all the variable options have detailed des-

#  criptions of what is being set.

#

#  This script requires methods from the RMXP SDK v 2.3 or higher. Ergo, this

#

#

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

#

#  SYSTEMS USED:

#  =============

#  As stated within the introduction,  this is a collection of scripts manupu-

#  lated to go beyond  their original expectations.   Most of those within the

#  the engine are Hidden Class scripts, scripts that were designed to simulate

#  or replace classes built into the RPGMaker game.exe itself.

#

#  Below is a list of the scripts put to use:

#

#  I would hope this is clear.  It is mostly plug-and-play, only requiring you

#

# * Resolution 

#   ----------

#   Selwyn's classic  script to redefine the size of the gaming screen. It has

#   been altered to no longer require the Display.DLL and a fixed 800x600 size.

#

# * Plane

#   -----

#   The plane class is a hidden class within RPGMaker engines where content is

#   drawn. Selwyn created his Plane class script that allows more control over

#   the drawing area, and it has been edited to use the values defined here.

#

# * RPG::Weather

#   ------------

#   This is an edit of the update method in the default RPG::Weather class. It

#   is very light (only the bottom section being altered) and with good amount

#   of comments. So if you follow the comments given,  adding a custom weather

#   script should be no problem.

#

#   Again notee that the code for the RPG::Weather has extensive notes within

#   for anyone adapting their own weather script in place.  This would be the

#   only hidden class script I would change given the number of replacements.

#

# * Spriteset_Map

#   -------------

#   First,  the structure of both the initialize and update methods HAVE been

#   heavily changed.  They have, in fact, been broken into smaller methods as

#   defined by the 2007 era RPGMaker SDK.  So SDK scripts would have no issue

#   with this system,  and normal uses likewise would not.   Apart from that,

#   the actual changes made  involve redefining the 'viewports' of the screen

#   to accommodate the window resolutions.

#

# * Spriteset_Battle

#   ----------------

#   First,  the structure of both the initialize and update methods HAVE been

#                     >   CONFIGURATION AND ENGINE PAGE   <

#==============================================================================

#==============================================================================

# ** ScrnSize

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

#  This module handles the adjustable screen size for games that utilize

#  resolution scripts to alter game window dimensions.

#==============================================================================

module ScrnSize

  # GAME SCREEN RESOLUTION

  # ======================

  # The absolute necessity... defining the size of the visible area of your

  # game on the screen. You will see below some dimensions tested, and then

  # commented out. Even reducing the size to older RPGMaker 2000 scale exe-

  # cuted just fine.

  # < -- IT IS RECOMMENDED THAT THE DEFINED VALUES BE MULTIPLES OF 32! -- >

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

  #

    Width     = 1280      # Screen area width in pixels

    Height    = 736       # Screen area height in pixels.

#    Width     = 640

#    Height    = 480

#    Width     = 320

#    Height    = 200

  # BATTLE SCREEN SIZE

  # ==================

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

  # A secondary requirement,  this value  defines the depth  of the default

  # battlesystem's main viewport. Defined as Viewport 1, it is where all of

  # the enemies appear,  where weather effects take place,  and screen tone

  # and shake effects are rendered.

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

  #

    BattleHeight  = 320       # Battle screen area height in pixels.

  # GAME INI NAMING

  # ===============

  # A necessity if you are renaming the Game Executable (eg Game.exe). When

  # your game/project is run, it looks for its requisite .ini file which it

  # assumes to have the same name as its executable. Many leave the name of

  # the executable alone. But if you choose to rename Game.exe to Trek.exe,

  # it will search for Trek.ini. And if the assumed ini does not exist, the

  # game will fail.

  #

  # The resolution changing system relies upon retriving the windows handle

  # for the game when it executes.  And for this, it needs the current name

  # of the Game's INI file.  So if you do change the name of the executable

  # (and thus the name of the INI), it needs the name defined below.

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

  #

    INI_Name  = 'Game.ini'

  # GAME EXECUTION SPEED

  # ====================

  # This is an old trick,  changing the speed of the executable to make the

  # game itself run faster.  RPGMaker XP was set to a default 40 frames per

  # second while RPGMaker VX and VXAce to a native 60 frames per second.

  #

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

  # Changing this value affects all...  script/code speed,  character speed

  # in the fieldmap, battle animations, and the like. RAMGE (10-120)

  # NOTE: Smooth mode refreshes graphics ever frame based on this value.

  #       Normal mode only refreshes every other frame.

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

  #

    Graphics.frame_rate = 40

#    RGSS / RPGMaker XP

#==============================================================================

#

#   INTRODUCTION:

#   =============

#   This is actually more of an option  given someone requested the ability

#   to use the map panoramas be used as the actual fieldmap rather than the

#   need for tiles.

#

#   This allows the game developer  to disable the odd scrolling options of

#   the panorama background and/or the fog display and have their positions

#   be fixed in relation to the map. What happens if they are enabled???

#

#   Panorama backgrounds do not have  any subtle scrolling affect like fogs

#   and will adjust and visibly scroll as any tileset terrain background.

#

#   While fogs  have vertical and horizontal scrolling options  to simulate

#   wind intensity,  the fog will not outwardly have an odd shift  when the

#   map shifts due to player movement.

#

#

#  INSTALLATION:

#  =============

#  This script requires methods from the RMXP SDK v 2.3 or higher. Ergo, this

#  script needs to be placed below the RMXP SDK,  or any collection of needed

#  SDK classes thereof.

#

#  RMXP SDK Methods manipulated:

#  * Spriteset_Map.update_panorama_plane * Spriteset_Map.update_fog_plane

#

#

#  INSTRUCTIONS:

#  =============

#  Very simple.  Any map that needs its Fog or Panorama 'fixed' in place

#  is to have its ID added into either the FOG and/or PANORAMA array in

#  the Fixed_Overlays module.
