====== Dungeon Master ==

The Dungeon Master in Crossfire is abbreviated " DM " or " Wiz " . \\

He has many functionality added, see the page [[:dm_commands]] .


====== Tips and Tricks ==

===== Goto Player's Unique Maps ==

The Dungeon Master may need to go to unique maps belonging to players located in the \\
{prefix}/var/players/<player name>/ directory.

Removing unwanted pets created by fumbled alchemantricity attempts inside a permanent apartment of a player may be a "service" to keep up the mood of the player.

It is by whatever reason also possible, that pets of a player following him to his apartment all of a sudden turn against him.

**But:** How to [[:dm_commands#goto]] to a player's unique map ?
 
<del>Simply link {prefix}/maps/players to point to the {prefix}/var/players directory.</del>

It needs to emulate the path as the server knows it, which is an absolute path {prefix}/var/crossfire/players.


On Linux in a terminal with server configured with --prefix=/usr/games:
<code bash>
cd /usr/games/share/crossfire/maps
mkdir -p  usr/games/var/crossfire
cd usr/games/var/crossfire
ln -s ../../../../../../../var/crossfire/players .
</code>
 
Then in the client issue the command \\
''goto /usr/games/var/crossfire/wiki/_scorn_apartment_apartments'' \\
if that player name and _apartment is already created.

===== Goto /City ==

When issuing the [[:dm_commands#goto]] command, the DM needs to type in awfully long /path/to/map arguments. \\
Especially for the maps inside the // /world// directory this is sometimes crazy for the need to know the coordinates every time. \\
One could think of just linking /Scorn to point to /world/world_105_116, but that fails to step on further attached world map tile maps because the \\
''tile_path_*'' key attributes have relative path as values.

The way to enable such shortcuts is to make the tile_path_* key values absolute path_names,
so they look as 
<file>
tile_path_1 /world/world_105_114
tile_path_2 /world/world_106_115
tile_path_3 /world/world_105_116
tile_path_4 /world/world_104_115
</file>
instead of 
<file>
tile_path_1 world_105_114
tile_path_2 world_106_115
tile_path_3 world_105_116
tile_path_4 world_104_115
</file>

Bash script using **sed** stream-editor to make the tile_path_ absolute: 
<code bash>
#!/bin/ash
du . #disk usage

for f in world_*
do

test -e "$f" || continue
test -s "$f" || continue

for nr in 1 2 3 4; do

if grep -i "tile_path_$nr" $f; then

 if grep -i "tile_path_$nr /world/" $f; then :
 else
 sed -i -r "s%tile_path_$nr (.*)%tile_path_$nr /world/\1%" $f || break 2
 fi

fi

sleep 0.01
done

sleep 0.01
done

du . # disk usage
</code>
This script assumes to be located inside the {prefix}/maps/world directory.

**NOTE:**Because of the many 900 map files, this script could take some minutes.

**Note:** A backup is probably advised before running that script.


On Linux we can then simply <code bash> ln -s world/world_105_116 Scorn</code> in the {prefix}/map directory.

The server needs to be restarted with empty TMPDIR /tmp temporary files.
 
In the client type ''goto /Scorn'' .
