I don't know. I've used it in the past...
And wow! Revisiting it, I was a bit ... Its demo is so old, it still had the original Japanese scripts within. A 2005 script, it isn't up to what was later considered 'standard' coding.
NOT to say it is sloppy, but it is hard to read, doesn't have the game classes arranged within properly defined orders, doesn't have the configuration variables within a module...
I'm looking at it... kinda... to see about (at least) proper formatting.
I will say that the use of ALIAS is correct, the coder using his name, the name of the script, and the name of the method within. Its possible that he set the standard for alias renaming within the RMXP SDK project since he was a member of that team.
As to your request, I would assume that it would be that you want certain events (heroic NPCs) to reveal the map area as if they were the player. I am unsure if it can be done. BUT... I need to examine this... thing!!!!

EDIT 1:
Well, I said I was considering 'proper formatting'... It sure helped. Consider THIS:
#-------------------------------------------------------------------------- # * Get map name #-------------------------------------------------------------------------- def map_name return load_data('Data/MapInfos.rxdata')[@map_id].name end #-------------------------------------------------------------------------- # * Frame Update: What tiles have been discovered or not currently covered #-------------------------------------------------------------------------- def update_fow_grid px = $game_player.x py = $game_player.y x = px - @fow_range start_y = py y = start_y count = 1 mod = 1
I think I kinda found WHERE to perform a simple bit of 'surgery' to the original script. The below change works:
#-------------------------------------------------------------------------- # * Frame Update: What tiles have been discovered or not currently covered # px : (Optional) x coordinate for target event revealing map # py : (Optional) y coordinate for target event revealing map #-------------------------------------------------------------------------- def update_fow_grid(px=$game_player.x, py=$game_player.y) # Define x/y update coordinates based on passed x/y values x = px - @fow_range start_y = py y = start_y count = 1 mod = 1
AND... it actually works.
By doing so, I can insert x/y coordinates into the command to reveal 'areas' outside of the player's coordinates, assuming I also pass a couple other commands too:
This was the result, the events around me vanished while the events in the 'circled' dynamic area were visible. Fixed by re-executing the commands with the focus on the player.

I've updated this script a bit and moved all the configuration options to the module, I'll make it available as soon as I'm on the computer. What you've shown is some progress. Although we still need to think about how to define events in the module table that can explore the map with the player but independently of him and assign them their own visibility radius. I haven't tested your demo yet so I don't know if this is exactly what I was thinking.
-------------------------------------------
Ou I see Your code is very very clearly than what i have done with original. But...i have one more option.
In my code You can set options of the map in script not in map name. This is helpful when You use location script and he download map name.

# ** 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.

Okay, this is my extended version of this script.
Now you can add fog of war to the map based on its ID and assign it any configuration!
Unfortunately it doesn't have the option to reveal the map through events yet, but with @DerVVulfman help there is a chance we can achieve that. :)

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:
Fog can be assigned to any map based on its ID number.
For each map, any fog configuration can be used.
To add another map, simply add the following code in the appropriate
section of the module:
{ :map_id => 1,
:fow_at_name => 'fow_default', # Name of the autotile file on map 1
:fow_static => true, # Use static fog on the map
:fow_static_opacity => 255, # Opacity of the static fog
:fow_dynamic => false, # Use dynamic fog on the map
:fow_dynamic_opacity => 100, # Opacity of the dynamic fog
:fow_hides_events => false, # Whether dynamic fog hides events
:visibility_radius => 3, # Visibility radius around the player
},
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.
