Roguelike Dungeon Darkness
Version: 0.9
Introduction
This is a modification of the Fog of War script that uses shadowcasting to extend the visible area to what the player could reasonably see. This method allows the developer to hide monsters, chests, and other events that aren't in the player's line of sight. Suspenseful! Just like a rougelike!

# ** 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.

=begin
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
=end

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)

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.)

FAQ
Q: Why is it laggy though?
A: Use MKXP or lower the value at
Code:
max_row = 19 #maximum screen tiles, lower if you experience lag.Compatibility
Compatible with anything the original Fog Of War script was. Probably NOT compatible with Random Maps, but hopefully will be fixed for a 1.0 release.
