This is a guide on what is an acceptable map and what is unacceptable.
Only acceptable maps will be put in the official Crossfire map distribution

------------------------------------------------------------------------------

Map Naming/Directory Scheme:

Note that these rules are ordered in importance, eg, if a rule conflicts,
the lower number rule takes precedence.

1) Each city should have its' own top level directory (eg, scorn, navar_city,
   santo_dominion) and be accessible on a world map. All buildings in the
   city and located nearby or related to it are in the respective city
   directory. City/town names are also used for nearby regions. If one
   desires to create a new city then create a new top level directory with
   the city name and use the new city name for the region in the maps that
   are associated with the new city.

2) If the map is part of a larger quest, a /quests/name_of_quest/ directory
   should be made, and all the maps for the quest placed in there (also see
   NOTE below about number of maps per directory). If some portions of the
   quest has maps in cities or other places, a README should be included
   explaining this. Note in general, having README's for all quests
   explaining the flow probably isn't a bad idea in the case someone else
   needs to work on it.

3) If a map is independent (eg, the map is one you just go there, kill and
   get exp), it should be in the /dungeons/ directory. If the dungeon is
   comprised of several maps (eg, multilevel dungeon), a subdirectory
   should be made to hold all of these maps (also see NOTE below about number
   of maps per directory).

4) Maps should fall into one of the categories above - if it does not, and
   you are not sure, send a message to crossfire-devel@lists.real-time.com.
   
NOTE: If a map or set of maps is near a particular city then place the proper
region in the map header. Use of the map maker's name as part of the
directory structure or map name is not encouraged and may result in maps
being excluded from CVS. While this type of directory scheme was done in the
past it is now deprecated. Attempt to use a logical tree structure for maps
and try to avoid dumping more than 15 to 20 maps in a single directory (this
does not apply to /world/). Dumping a massive number of maps in a single
directory is highly discouraged, Just Say No.

------------------------------------------------------------------------------

1) Check that all exits lead where they are supposed to.  Unless there is
a specific reason an exit leads only one direction (like a trap door or
perhaps a teleporter), players should be able to exit back from where they
came from right when they enter the map.

One way exits/entrances should only be used on objects in which it is
obvious it is one way.  A house is not an obvious one way entrance.  Remember,
players may not have the three hours of time it takes to find the exit
after being trapped in a map (a work around for this can be have the trap
lead to a safe place with no exit which contains a savebed.  Thus, the 
player could save and come back at a later time to find the exit.)

2.1) Try to make sure the maps are multi player accessible.  In towns, this
means the road should be at least a couple squares wide, buildings should not
be trapped in corners in which case one character standing in front blocks
access, etc.

2.2) Try to make corridors in dungeons or mazes a few squares wide -
especially if there is only a single path.  If it is a maze with several
different paths, single width corridors are acceptable.  The main problem
here are big labyrinths in which only one monster attacks at a time, and
which there is only 1 or two routes.  If two players enter such a map, the
one that went in first will be in the lead the entire time.

2.3) Avoid spiral or single path mazes that just have monsters lining the
corridor.  These are not very good for multiple players, not particularly
interesting (map justs consists of killing all the monsters), and tend to be
an easy and safe way to gain experience.

3) Don't put:

3.1)  extremely valuable treasure right next to the entrance, or
nearby.  Players should need to work to get treasure.  If the treasure is
fairly worthless (food, or non magical items), this would be acceptable.
But a character should not be able to pop in, pick up a potion, spellbook,
or a lot of diamonds, and then pop out again, without ever meeting
a monster.

3.2) Don't put monsters of high experience point near to entrance where they
are trapped. Low level player could boost their experience high by using some
weapons or spells from distance without danger. For example find a trapped
troll and get wand of fireball.

3.3) monsters on top of other monsters.  A troll should not be sitting on
top of an oriental dragon.  The only exception to this would be if a monster
could be on top of another monster (making sense) and hiding it at the same
time.  A troll on top of an oriental dragon does not make sense (could not
fit), nor can the troll hide the oriental dragon.  Using tricks like these
which are only applicable due to display limitations is something that
should not be done, nor should the player need to click on every monster he
encounters to see if something is below it. (as a side note, doing this
will tend to lock the monsters into position, making them unable to move.)

3.4) Large groups of monsters that can be killed quickly with spells.  A
fairly popular tactic to make high level maps is just to put 30 dragons (or
other tough monsters) in a big room.  Do not do this.  All the player needs
to do is cast a dozen icestorms, and quickly gets millions of experience.
Likewise, it is unlikely that any more than 2 or 3 large (multisquare)
monsters will be able to attack a player or party at once - the remaining 25
will be blocked from doing anything.  This then makes it so that having 30
dragons is not any tougher than having 3.

 If you want to make a high level map, instead of tossing a lot of monsters
on it, take existing monsters and make them tougher.  Increase their
hit points, level (which then means spells they use do more damage), add
immunities or protections, remove vulnerabilities, change attack types, etc.
Try not to totally change the characteristics of a known monster - a normal
dragon should still be dragon like.  Also, remember to adjust experience
that the monster gives.

4) Try to keep the treasure in line with the difficulty.  5 potions should
not be given out for defeating orcs or gnolls (even if there are a lot
of them), but if you need to defeat several dragons to get to the
potions, that is fine.  Likewise, if it is likely a lot of spells will be
needed to defeat the monster, and those spells have a chance of destroying
the items, then perhaps a few extra items to take this into consideration
is not a bad idea.

5) If use of a specific skill/class/spell is needed to complete the map,
that should be stated near the map entrance.  How clearly this is stated
depends on the circumstance.  If use of a certain skill is needed, there is
probably no good way other than to state that a skill is needed.  If use of
a certain spell is needed, stating that a spell caster of XX level might be
sufficient, with the assumption that a spellcaster of that level would have
the spell.  It is safe to assume that all characters can fight, but
spellcasting (especially certain spells) should not be assumed, and thus
should be stated.

Also, don't put in hidden rooms requiring dimension door if they only real
way to know about them is pure luck or looking at the map.  If you want to
do something like that, at least put some clues in.

If a certain skill would make a map easier, but is not required, you don't
need to necessary state it.  The idea of this is that it can be frustrating
to wander into some map, complete most of it, but find out you can't
finish the map because you lack some skill or spell.

5.1) A map should be designed so that a character can never be
trapped in a room (except via other player interaction.)  A character should
never be forced to dimension door or word of recall out of a map because
some gate closed behind him.  For a character without these spells,
it would mean death.  A simple method around this is put a lever on
both sides of the door.  If the door is opened by special actions (saying
things, dropping things), just put the lever on the hard to get side of
the gate.

6) If a map require multiple players to simultaneous be on it to solve
the map, put a sign or message so players know.  Such maps would be those
that require manipulation of levers or buttons in certain sequences in
order to get through gates.

Don't make ends of maps require multi users.  This ruins that map for
single players (not able to complete it), and makes a map that requires
multiple players for only a small portion.

7) Try not to make the maps too many levels deep.  To get to the goal,
it should not require a 6 hour continous sitting, as the player works
through each map to get to the next.  Multi level maps are fine - just
don't over do it.  One way to do this is have several maps with a key
or other special item at the end.  The final map could have the various
battles, and then a series of gates/altars which uses up these keys.

8) Shops:

8.1) Don't put super stores in any towns or villages you create.  With the
growing number of maps, players can already make a trip to all the different
towns to try and find certain items.  A one stop find all shop is not
interesting.  A good maximum size is about the same size of the shops
in the starting village.

Also, making six magic shops of that size and putting them in the same
town is not any better than one large magic shop.  If you want to have
specialized shops, then make each shop smaller.  If you just want one
shop that sells every type of item (magic, armor, weapons, food, etc), then
a large shop is permissable.

8.2) Make sure the entire interior the shop is covered with tiles.  Likewise,
don't put shops that lead to areas without tiles without going over one of
the 'magic doormats'.  A player should never be able to get an unpaid
item out of a shop, whether via exit that does not go over the magic
doormat, or through spells.


9) Don't make maps which require high level characters that low level
characters can wonder into without warning.  Put a warning sign nearby,
or gates or doors so the player can see they are in over their head, instead
of instantly getting toasted the second they enter the map.


10) The structure of the map should make sense.  That is to say,
if you enter a house, the house should then not have a tower inside.  Or
a door to a shop.  In other words, if a map has an exit to another map,
that exit should make sense (ie, another level, tunnels, dungeons
all make sense.  However, another building the size of the original
does not make sense.


11) Try to keep the difficulty throughout the map(s) about the same.
The first monster in the map should not be the most difficult monster,
nor should the last monster be orders of magnitude more difficult
than anything before it.

It is very frustating to play a map, killing most every monster without
much difficulty, only to find that last monster unkillable.

It is reasonable to have the monster increase in difficulty.  Also, if the
map has no quest or end goal, then having a very difficult monster around is
not unreasonable, as long as it does prevent the player from progressing to
the next map.

12) Do not put directors with bullet, lightning, fireball, etc. that
are a loop or continuous.  Example:  Do not have two directors, each
facing each other, with a bullet wall firing into them at the side.

 Having numerous directors is fine.  But make sure that eventually,
there will be an exit/detonation point for the fired spell.  Having
loops that go for over typically bring the game to a halt, as the
objects just multiply and the game consumes more and more cpu time.


------------------------------------------------------------------------------
The following are various suggestions for making good or interesting
maps.  A map that does not need to follow all these hints to be accepted,
but following these hints will make for more interesting or playable maps.


1) Try to create only small maps.  If you have a large map in mind, try to
see if you can possible split it up in several separate sections, and place
those sections in different maps.  Many small maps use much less memory than
one large map, since crossfire doesn't yet support swapping of portions of
maps.  Also, with small maps, the time to load it from and store it to disc
becomes so short that it's impossible to notice.  In this context, small
means about 32x32, though it's actually the number of objects in the map
which count.

What is potentially more critical than the size of the map is the number 
of objects (memory usage), and live objects (cpu usage, as each would need
to be processed.)  

Also, remember that if you make very large maps, all generators will be
cranking out monsters whenever anyone is on it.  This could mean that a lot
of monsters have been generated before a player even gets to the area where
they are being created.

Related to this:  If a map contains multiple levels, make multiple maps.
Many times, if the level is small, the mapmaker may think I will just put
all the levels on one larger map.  This makes the map a little less readable
to others.  Also, things like magic mapping and dimension door can lead to
unexpected results.

2) Make a plot!  A map withot a plot becomes just another mindless
"Kill'em all".  For instance, create a story which explains why there
are npc's here and monsters there, fragment the story up and put
bits and hints of it in various writables (books) and npc-conversations.

If you are going to make a mindless kill them all map, at least put some
reward in the map that can only be accessed after all the monsters have been
killed.  The only thing worse than a kill them all map is a kill them all map
which you get nothing out of.

Avoid maps where all the monsters are lined up, and only one can attack
you at a time.  This just makes an easy (and relatively safe) way for
a character to gain experience and treasure, and is not especially
interesting or challenging.

2.1) A good idea for the rewards at the end of quests are specific 
items (luggage, spellbook of some otherwise not available spell,
special weapon, spellcrystal, etc.)  It is much more interesting to
put a specific item instead of something like a random artifact.  Feel
free to mutate or otherwise change existing artifacts to create your own.

 This has two advantages: one, the player will get to know where certain
items are.  Having to search endlessly for a specific item gets tedious.
Two, it reduces the incentive to keep repeating the quest (repeating
quests is not inherently bad)  If the reward is a random artifact, a player
may very well keep repeating the quest until the item he looks for comes up.
By doing specific items, this will not happen.

3) Make puzzles!  Use all those different object types: buttons, handles,
doors, altars, pedestals, triggers, timed gates, etc...  Hide special "keys"
needed to get further in special places, and use text-puzzles to describe
where they are hidden and how they must be used.  The possibilities are
endless!  Remember, you can also hide buttons under floors, making it more
difficult for the character to find the trigger points.


4) But don't make too much big labyrinths. Making of labyrinths is (too)
easy with crossedit, just select auto-joining and make zig-zag with mouse.
But the results of these are quite tiring.  If you make ones, try make
some idea into it.

Related: Don't make maps where the only way to find something is examination
of each and every wall.  For example, don't have a big map with lots of walls,
but the key to moving onward is to find the weak wall and pass through it.
Nor should big mazes full of invisible walls be made where the way to get
through it is just by going in some direction, finding out you can't move
anymore in that direction, go some other one, etc.

5) Give the npc's information!  An npc's knowledge about hidden treasure surely
makes it interesting to have a conversation with it.


6) Feel free to add some traps, but be careful to not make them too
  deadly without adequate warning.


7) Don't mix the monsters too badly.  Let there be at least some logic
behind why they are grouped in a single room.  Undeads together with
undeads, for instance, but not together with kobolds...
Big dragons usually don't live together with mice...  Fire immune creatures
generally dislike ice immune creatures.

Also, limit use of monsters that multiply rapidly (mice, slimes).   A map
that is easily overwhelmed with these creatures quickly becomes useless.

8) Give your maps a meaningfull name (like John's tower, level 1).
This way, these can be used instead of the map paths in the highscore
file.  Also, in terms of the actual file name, try to use numeric 
level identifiers (ie, maze.1, maze.2, ... instead of maze.first, maze.second,
etc.)  The former maps the levels sorted a little bit nicer in the
directory.

9) Try to make the map so that it links in with the existing world.  Most
people want to make their own continent, which is then accessed by ship
or other fast means.  While convenient, this creates many island
continents.  The problems with this are that any feeling of relation is lost
(where is that island continent), and it makes item searching in shops very
easy - if you can access half a dozen shops quickly and safely by taking
boats, you have a decent chance of finding the item you want.

Also, it seems that when most people start making maps, the first thing they
do is create a new town or village.  There are already a lot of towns and
villages out there.  If you are just going to create a few new buildings,
instead of going to the effort and time of creating your own island with a
town, just create the buildings, and plug them into one of the existing
towns or the terrain someplace.  Many of the towns right now have many
unused buildings.

------------------------------------------------------------------------------

Technical map hints:

1) If you are creating a new archetype, it only needs to go into the general
archetype distribution if it has an image associated with it, or it has
general use (a new monster).  Something that uses already existing images
can be set up in the map file itself (through setting various variables).

2) When modifying an existing archetype into a new one (either new face
or new type), use the archetype that has the most variables in common.
Thus, if you want to create a monster called a 'bouldar', it is probably
best to take a monster of some sort and change its face instead of taking
the existing boulder archetype and changing its type, hit points, speed,
etc.

3) Changing color is no longer possible in maps - instead, a new face
and image must be created, and then put in the standard distribution.
The archetype collection script will automatically pull out face information
from archetype files.

4) Try to keep maps readable by other people who might edit them.  Thus,
instead of modifying a woods space so it also acts as an exit, just put an
invisible exit under the woods space.  This has the same functionality, but
it makes it much easier for other players to see what this space does. (Side
note - if you want it so that players actually need to apply the space
to enter, you will need to change the face of exit for this to work.  If
you do this, you should also accompany it with a magic mouth.)

5) Make sure you set the difficulty field in the map attributes to
somethign meaningful.  Crossfire will calculate a default dificulty, 
but its formula is hardly ideal.  The difficulty of a map determines how
magical the treasure will be (and some treasure types won't show up 
unless the map has a certain difficulty level.)

6) Don't be too intimidated about writing new code if there is something
you would like to be able to do, but just isn't supported.  If you are not
the code writing time, make a suggestion.  Worst case is it gets ignored.
But many times, I have written code because I had some idea which just
was not possible at the time (ie, the apartment in the starting town
required an expansion/change of the unique item code.)
