#define OB_SPELL_TAG_HASH (   op,

)    (op->spell_tags[count&0xf])

Get the hash on an object for a specified count.

Parameters
opwhat to check.
countitem to check the hash for.

Definition at line 87 of file object.h.

Referenced by object_merge_spell().

#define OB_SPELL_TAG_MATCH (   op,
  count

Definition at line 93 of file object.h.

Referenced by object_merge_spell(), and ok_to_put_more().

#define SPELL_TAG_SIZE   16

Defines default size of the *spell_tags pointer. The OB_SPELL_TAG_HASH is a simple mechanism to get/set the spell tags based on a simple hash - it should change if the tag size also changes. Note that since count is used for this, this value is effectively random or at least fairly evenly distributed, at least in the low bits. And a size of 16 lets us do a very fast operation.

Typedef Documentation

typedef struct archt archetype

The archetype structure is a set of rules on how to generate and manipulate objects which point to archetypes. This probably belongs in arch.h, but there really doesn't appear to be much left in the archetype - all it really is is a holder for the object and pointers. This structure should get removed, and just replaced by the object structure

One body location. See common/item.c.

typedef struct _key_value key_value

Each object (this also means archetypes!) could have a few of these "dangling" from it; this could also end up containing 'parse errors'.

key and value are shared-strings.

Please use object_get_value(), object_set_value() from object.c rather than accessing the list directly. Exception is if you want to walk this list for some reason.

typedef struct obj object

Main Crossfire structure, one ingame object.

Note that the ordering of this structure is sort of relevent - object_copy() copies everything over beyond 'name' using memcpy. Thus, values that need to be copied need to be located beyond that point.

However, if you're keeping a pointer of some sort, you probably don't just want it copied, so you'll need to add to common/object.c, e.g. copy-object

I've tried to clean up this structure a bit (in terms of formatting) by making it more consistent. I've also tried to locate some of the fields more logically together (put the item related ones together, the monster related ones, etc. This structure is best viewed with about a 100 width screen. MSW 2002-07-05

See the documentation page for more details.

typedef struct oblnk objectlink

Used to link together several objects

typedef struct oblinkpt oblinkpt

Used to link together several object links

typedef uint32_t tag_t

Object tag, unique during the whole game.

Definition at line 12 of file object.h.

Enumeration Type Documentation

Only add new values to this list if somewhere in the program code, it is actually needed. Just because you add a new monster does not mean it has to have a type defined here. That only needs to happen if in some .c file, it needs to do certain special actions based on the monster type, that can not be handled by any of the numerous flags. Also, if you add new entries, try and fill up the holes in this list. Additionally, when you add a new entry, include it in the table in common/item.c

type 0 is undefined and indicates non-valid type information.

Referenced by cast_invisible(), init_objects(), object_count_active(), object_update_speed(), and process_events().

The ordering of this is actually doesn't make a difference However, for ease of use, new entries should go at the end so those people that debug the code that get used to something being in the location 4 don't get confused.

The ordering in save_name, use_name, nonuse_name. save_name is the name used to load/save it from files. It should match that of the doc/Developers/objects. The only real limitation is that it shouldn't have spaces or other characters that may mess up the match code. It must also start with body_ use_name is how we describe the location if we can use it. nonuse_name is how we describe it if we can't use it. I think the values below will make it pretty clear how those work out They are basically there to make life a little easier - if a character examines an item and it says it goes on 'your arm', its pretty clear they can use it. See the last sample (commented out) for a dragon Note that using the term 'human' may not be very accurate, humanoid may be better. Basically, for the use/nonuse, the code does something like: "This item goes %s\n", with the use/nonuse values filling in the s
