Map was just loaded, handle op's initialisation.

Generates shop floor's item, and treasures.

Here is the caller graph for this function:

static char* cat_template ( char *  source, char *  add  )

static

Concatenates a string, and free concatenated string.

Parameters

source	string to append to. Can be NULL.
add	string that is appened. Will be free()d after. Must not be NULL.

Returns

new string that should be free()d by caller.

Definition at line 112 of file bwp.c.

void clean_tmp_files

(

void

)

Remove temporary map files.

Todo:

check logic, why is file only removed if map is in memory?

Definition at line 811 of file bwp.c.

static char* do_template ( const char *  template, const char **  vars, const char **  values  )

static

Processes a template.

Variables in the form #VARIABLE# will be substituted for specified values.

Parameters

template	template to process.
vars	variables to replace. Array must be NULL-terminated.
values	variables to replace by. Must be the same size as vars, no NULL element allowed.

Returns

filled-in template, that must be free()d be caller. NULL if memory allocation error.

Note

returned string will be a memory block larger than required, for performance reasons.

void dragon_ability_gain	(	object *	ob,
		int	x,
		int	y
	)

When a dragon-player gains a new stage of evolution, he gets some treasure.

Parameters

who	the dragon player.
atnr	the attack-number of the ability focus.
level	ability level.

void draw_ext_info	(	int	flags,
		int	pri,
		const object *	pl,
		uint8	type,
		uint8	subtype,
		const char *	txt,
		const char *	txt2
	)

Those are dummy functions defined to resolve all symboles. Added as part of glue cleaning. Ryo 2005-07-15

Definition at line 790 of file bwp.c.

References logfile.

void draw_ext_info_format	(	int	flags,
		int	pri,
		const object *	pl,
		uint8	type,
		uint8	subtype,
		const char *	new_format,
		const char *	old_format,
			...
	)

Sends message to player(s).

This function is the same as draw_ext_info, but takes varargs format. Otherwise, the meaning of all the fields is the same. This is perhaps not the most efficient as we do vsnprintf on both the old and newbuf, but it simplifies the code greatly since we can just call draw_ext_info. Also, hopefully at some point, need for old_format will go away.

Parameters

flags	Various flags - mostly color, plus a few specials.
pri	Priority. It is a little odd - the lower the value, the more important it is. Thus, 0 gets sent no matter what. Otherwise, the value must be less than the listening level that the player has set. Unfortunately, there is no clear guideline on what each level does what.
pl	Can be passed as NULL - in fact, this will be done if NDI_ALL is set in the flags.

If message is black, and not NDI_UNIQUE, gets sent through output buffers. If the client supports the new readables, this is sent to the client without processing in the output buffers.

Parameters

type	The type MSG_TYPE for the type of message.
subtype	The type MSG_TYPE for the type of message.
new_format
old_format

void emergency_save

(

int

x

)

Save all players.

Parameters

flag	if non zero, it means that we want to try and save everyone, but keep the game running. Thus, we don't want to free any information.

Definition at line 808 of file bwp.c.

void esrv_del_item	(	player *	pl,
		int	tag
	)

Tells the client to delete an item. Uses the item command with a -1 location.

Definition at line 827 of file bwp.c.

void esrv_send_item	(	object *	ob,
		object *	obx
	)

Sends item's info to player.

Definition at line 814 of file bwp.c.

void esrv_update_spells

(

player *

pl

)

This looks for any spells the player may have that have changed their stats. It then sends an updspell packet for each spell that has changed in this way.

	)

Writes to everyone on the specified map

object* find_skill_by_number	(	object *	who,
		int	skillno
	)

This returns the skill pointer of the given name (the one that accumlates exp, has the level, etc).

It is presumed that the player will be needing to actually use the skill, so a skill tool will be equipped if one if found to benefit from its bonuses.

This code is basically the same as find_skill_by_name() above, but instead of a skill name, we search by matching number.

Parameters

who	player applying a skill.
skillno	skill subtype.

Returns

skill object if player can use it, NULL else.

Definition at line 823 of file bwp.c.

void fix_auto_apply

(

mapstruct *

m

)

Go through the entire map (only the first time when an original map is loaded) and performs special actions for certain objects (most initialization of chests and creation of treasures and stuff). Calls auto_apply() if appropriate.

Parameters

m	map to fix.

static void free_if_used ( char *  p )

static

Frees memory if the pointer was ever given a string.

There's probably a cleaner way to do this, but this frees the memory given to a pointer if the pointer points to a string longer than zero length. It's to get rid of "in free(): warning: junk pointer, too high to make sense" errors.

Parameters

p	Pointer to free memory from

const char* const flag_names[NUM_FLAGS+1]

This is a list of pointers that correspond to the FLAG_.. values. This is a simple 1:1 mapping - if FLAG_FRIENDLY is 15, then the 15'th element of this array should match that name. If an entry is NULL, that is a flag not to loaded/saved.
