Fog Of War 2.0 (Neblina De Guerra No RMXP)

Fog Of War 2.0 é um script desenvolvido por Wachunga, para o RPG Maker XP, que, ao ser instalado num jogo ou projeto, ele ativa uma Neblina De Guerra similar a jogos de estratégia em tempo real, como o StarCraft, Warcraft e outros.

A demo é auto explicativa, e vem com um script do Near Fantastica, o Dynamic Maps, embora modificado pelo Wachunga.

Código

O código do Fog Of War deve ficar acima do Dynamic Maps que, por sua vez, deve ficar acima do Main:

# ** Fog of War
#------------------------------------------------------------------------------
# Version 2.0, 2005-11-21
# by Wachunga
#==============================================================================
=begin
 0.8 - original release
 0.85
   - added colour parameter to map names
   - fixed bug where map grids overlapped
 0.9
   - switched over to a tilemap (from a sprite)
   - now more compatible with minimap scripts (but they'll have to take
   extra tilemap into account)
 1.0
   - switched over to an autotile instead of using a custom tileset
     * edges looks nicer, but gradual fading had to be removed
     * colour parameter no longer possible (set by autotile)
   - move event (including jumping and speed changes) bug fixed
   - teleportation bug fixed
   - some optimization
   - made compatible with Cogwheel's Pixel Movement script
     (see http://www.rmxp.net/forums/index.php?showtopic=24716 for details)
 1.01
   - fixed bug when teleporting from map without fow to a map with fow
 2.0
   - now two independent types of fog of war:
      * static, which never returns (i.e. typical RTS "terrain" fog)
      * dynamic, which returns once out of visual range and can optionally
        hide map events (i.e. typical RTS "unit" fog)
   - now using a compact version of Near's Dynamic Maps script
   - fog of war is now above weather and normal fog
   - added support for much larger visual ranges (0 - 9)
   - added support for option to set up fog of war from a call script event
     command
   - optimization

 A map specified as having "fog of war" (fow) has tiles that are (fully or
 partially) obscured until the player gets within visual range. The amount of
 fow to disappear as the player moves depends on the visual range specified.
 Gamers with experience playing Real Time Strategy games like Warcraft, Age of
 Empires, etc. should be quite familiar with the concept.

 This script supports two kinds of fog of war: static and dynamic.

 Static fow is the kind that typically hides terrain in RTS games. It covers
 the entire map until the player explores the area, discovering the underlying
 terrain. Once static fow disappears from an area of the map, it stays gone
 indefinitely (even if loading a saved game, leaving the map and returning
 later, going to the menu, etc).

 Dynamic fow is identical to the static kind except that it doesn't stay gone
 forever: as soon as the player leaves visual range of an explored tile,
 dynamic fow covers it again. This kind of fow is typically used to hide enemy
 units in RTS games.

 SETUP:
 
 There's no need to add the autotile via the database. Just place the
 file in the autotile folder, import it, and change the FOW_AT_NAME constant
 to the appropriate filename. To change the colour of the fog of war you must
 create a new autotile. (However, opacity is customizable by constants below.)
 
 To indicate a map is to have either (or both) of these kinds of fog of war,
 include <fow> in its name (via "Map properties"). To enable both static and
 dynamic fow, you can either add nothing more (since it's the default), or
 add <s><d> (or <d><s>). To enable one or the other, just add the appropriate
 one (e.g. <s> for static, <d> for dynamic). You may also optionally specify a
 visual range between 0 and 9 in the map name (e.g. <5>), noting that 3 is
 the default. Here are some example map names:
 "your-map-name <fow><2>" (defaults to static&dynamic on; range specified as 2)
 "your-map-name <fow><s>" (only static fow is on; range defaults to 3)
 "your-map-name <fow><d><8>" (only dynamic fow is on; range specified as 8)
 
 Alternatively, fog of war can be setup via a call script event command using
 the fog_of_war global method. Detailed instructions are just before
 the method itself.

 Finally, an edited version of Near Fantastica's Dynamic Maps script needs
 to be below this one. You may find it at the following URL:
 http://www.rmxp.net/forums/index.php?showtopic=24716
 
 The ranges work as follows:
 range = 0 reveals just the square on which the player stands

 range = 1 is the same as range 0 plus four adjacent tiles
 i.e.   @
       @P@
        @

 range = 2 is the same as range 1 plus eight additional tiles
  i.e.  @
       @@@
      @@P@@
       @@@
        @

 range = 3 (default) is the same as range 2 plus twelve additional tiles
  i.e.  @
       @@@
      @@@@@
     @@@P@@@
      @@@@@
       @@@
        @

 etc.

 Note: I've taken great pains to optimize this script as much as possible
 (which unfortunately reduces the readability of the code). There shouldn't be
 much visible effect on frame rate.

 Setup fog of war.
 
 This method is an alternative to using the default map name method, and
 is designed to be called from a call script event command. This allows
 fog of war to be dynamically enabled or disabled during gameplay.
 
 Parameters:
 static - if true, static fow enabled
 dynamic - if true, dynamic fow enabled
 (if both of the above are false, fow is totally disabled)
 range (optional) - the visual range of the player
                    * default is FOW_RANGE_DEFAULT
 reset (optional) - if true, fow for this map resets entirely (i.e. previously
                    explored areas are covered again)
                    * default is false
                    
 Sample calls:
 fog_of_war(true,true,5) - enable both static and dynamic fow with range of 5
 fog_of_war(false,false,3,true) - disable and reset both types of fow

    The function to return the index of a single tile within an autotile
    (given by at_index) is (at_index-1)*48 + col-1 + (row-1)*8
    (where row, col, and at_index are again NOT zero-indexed)

=begin
   The following array lists systematic keys which are based on adjacent
   walls (where 'W' is the wall itself):
   1 2 3
   4 W 6
   7 8 9
   e.g. 268 is the key that will be used to refer to the autotile
   which has adjacent walls north, east, and south.  For the Castle Prison
   tileset (autotile #1), this is 67.

   (It's a bit unwieldy, but it works.)
