====== Information and Tips ======

===== Commenting .arc Files =====

* The number sign (#) may be used as a comment character in .arc files.


====== Making Archetypes ======

Monsters, walls, tiles, and practically everything else in Crossfire are Archetypes. Archetype is often abbreviated to "arch".

To make and test your own archetype, you will need:
  * [[the_source|the server sources]]
  * if you are under Linux {FIXME other architectures}, you need to have the server built
  * a working Crossfire server
  * the archetypes collection
  * Perl.
  * It is highly recommended that you also have the [[gridarta|crossfire editor]]

===== Items =====

==== Potions ===

=== Making a New Potion ===

Some may find it easier to take an existing potion and tweak all the stats on it to ultimately create a "new potion."

  * If you want it to show up in shops, the shop file needs to be updated. This file is located in the **archetypes** directory at: shop/Floors/shop_potion.trs
    * Be sure to follow this format:

    more
    arch potion_<foo>
     chance <number>

    * If you want players to be able to create the potion through alchemy, you will need to update the alchemy formula file.  This file is located in the **server** directory at: lib/formula
      * Be sure to follow this format or syntax:

    # -- <comment or brief summary>
    Object <as found in the archetype file>
    arch <graphic_name>
    chance <number>
    diff <number>
    exp <number>
    yield <number>
    skill alchemy
    cauldron cauldron
    ingred <ingredient1,ingredient2,etc>

  * If you want players to be able to find the potion in dungeons or through random chance, you will need to update the treasure generation file.  This is located in the **server** directory at: lib/treasures
    * Be sure to follow this format:

    more
    arch potion_<foo>
     chance <number>

=== Modify Existing Potion ===

FIXME -- Modify Existing Potion section is a draft and work in progress

  - Locate the //object name// of the potion in question. You can find this while in game and in DM mode by using the //dump// command on an existing potion id number.
  - Locate or search for the object name in the archetype files. You can use the grep command or search for text in the Archetype files that contains a key word in the potion name, this will probably require some trial and error.
  - Edit the .arc file with the changes you want to make.  Examples include changing the name, modifying the potion duration, the potion appearance (aka graphic), and so on.
  - Save the file with your changes.

== If the potion name changed ==

  * You will need to update the shop file. This file is located in the **archetypes** directory at: shop/Floors/shop_potion.trs
    * FIXME - where is the shop_potion.trs file in branch?
  * You will need to update the alchemy formula file.  This file is located in the **server** directory at: lib/formulae
  * You will need to update the treasure generation file.  This is located in the **server** directory at: lib/treasures
  * You will need to search through all the **map** files and update any references to the old (object) name as well.
  * Let the developers on the Gridarta (map editor) project know about the change so they can update the pickmap (ex: trunk/crossfire/resource/pickmaps/treasure)

===== Map Features =====

==== Buildings ====

FIXME describe multi-tile building special requirements and address how to specify which tile is the "head", and what/where attributes are placed.  Some note s  describing object types seem to imply that it is not necessary to replicate properties on parts other than the "head".

===== Monsters =====

==== Modify Existing Monster (Example) ====

We will create a new goblin called "Goblin War Lord".

  - cd into your base arch directory
  - Then go under: monsters/goblin/ 
  - Copy the file goblin.arc to goblinwarlord.arc
  - Open goblinwarlord.arc file
  - Change the file to this:

  Object goblinwarlord
  name Goblin War Lord
  randomitems goblin
  race goblin
  face goblin.111
  color_fg green
  anim
  goblin.111
  goblin.112
  mina
  monster 1
  sleep 1
  Wis 13
  no_pick 1
  alive 1
  exp 140
  ac 10
  wc 14
  dam 5
  hp 20
  maxhp 20
  level 3
  speed 0.1
  weight 50000
  run_away 10
  will_apply 2
  pick_up 24
  can_apply 25
  can_use_wand 1
  can_use_bow 1
  can_use_ring 1
  can_use_shield 1
  can_use_armour 1
  can_use_weapon 1
  editable 1
  body_finger 2
  body_torso 1
  body_head 1
  body_shulder 1
  body_foot 2
  body_wrist 2
  body_hand 2
  body_waist 1
  body_arm 2
  body_range 1
  end

====== Testing Archetypes ======
If you have compiled before go into the crossfire/lib directory (if not go here: [[server:server_compiling]]): 

   $ cd /home/<username>/server.svn/lib

delete the old archetypes file:

   $ rm archetypes

and then build the new archetypes file:

   $ make archetypes

navigate back to the server server directory:

   $ cd ..

Double check that you are in the correct directory which is the server directory:

   $ pwd
   /home/<username>/server.svn

compile the server:

  $ sh autogen.sh && make && sudo make install

FIXME describe more in detail, explain about the manual ''perl collect.pl'' method then make install, stuff like that :)

To see what you have made, either put it in a map, or create it using a Dungeon Master command.
