Detailed Description

All archetype-related functions.

Note: The naming of these functions is really poor - they are all pretty much named '.._arch_...', but they may more may not return archetypes. Some make the arch_to_object call, and thus return an object. Perhaps those should be called 'archob' functions to denote they return an object derived from the archetype. MSW 2003-04-29

Todo:: make the functions use the same order for parameters (type first, then name, or the opposite).

static void add_arch ( archetype * at )

object* arch_to_object ( archetype * at )

Creates and returns a new object which is a copy of the given archetype. This function returns NULL if given a NULL pointer, else an object.

Parameters

at	archetype from which to get an object.

Returns: object of specified type.

Note: get_object() will either allocate memory or call fatal(), so returned value is never NULL.

object* create_archetype_by_object_name ( const char * name )

Creates an object given the name that appears during the game (for example, "writing pen" instead of "stylus").

Parameters

name	the name we're searching for (ex: "writing pen"), must not be null

Returns: a corresponding object if found; a singularity object if not found.

Note: Note by MSW - it appears that it takes the full name and keeps shortening it until it finds a match. I re-wrote this so that it doesn't malloc it each time - not that this function is used much, but it otherwise had a big memory leak.

object* create_singularity ( const char * name )

Creates a dummy object. This function is called by get_archetype() if it fails to find the appropriate archetype. Thus get_archetype() will be guaranteed to always return an object, and never NULL.

Parameters

archetype* find_archetype_by_object_name ( const char * name )

This function retrieves an archetype given the name that appears during the game (for example, "writing pen" instead of "stylus"). It does not use the hashtable system, but browse the whole archlist each time. I suggest not to use it unless you really need it because of performance issue. It is currently used by scripting extensions (create-object). Params:

Parameters

name	the name we're searching for (ex: "writing pen")

Returns: the archetype found or NULL if nothing was found

archetype* get_archetype_by_skill_name	(	const char *	skill,

Retrieves an archetype by skill name and type. This is a lot like the other get_archetype_ functions, with different options.

Parameters

skill	skill to search for. Must not be NULL.
type	item type to search for. -1 means that it doesn't matter.

Returns: matching archetype, or NULL if none found.

archetype* get_archetype_by_type_subtype	(	int	type,

Retrieves an archetype by type and subtype. Similiar to other get_archetype_ functions. This returns the first archetype that matches both the type and subtype. type and subtype can be -1 to say ignore, but in this case, the match it does may not be very useful. This function is most useful when subtypes are known to be unique for a particular type (eg, skills)

Parameters

type	object type to search for. -1 means any
subtype	object subtype to search for. -1 means any

Returns: matching archetype, or NULL if none found.
