Detailed Description

Functions related to attributes, weight, experience, which concern only living things.

Todo:: make "stat"/"attr" coherent.

#define ADD_EXP	(	exptotal,
		exp
	)	{exptotal += exp; if (exptotal > MAX_EXPERIENCE) exptotal = MAX_EXPERIENCE; }

Handy little macro that adds exp and keeps it within bounds.

Since we are now using 64 bit values, I'm not all concerned about overflow issues with exptotal wrapping. exptotal is typically op->exp, or op->perm_exp

#define DIFF_MSG	(	flag,
		subtype1,
		subtype2,
		msg1,
		msg2
	)	draw_ext_info(NDI_UNIQUE, 0, op, MSG_TYPE_ATTRIBUTE, (flag>0)?subtype1:subtype2, (flag>0)?msg1:msg2, NULL);

Rather than having a whole bunch of if (flag) draw.

. else _draw, make this macro to clean those up. Not usuable outside change_abil function since some of the values passed to draw_ext_info are hardcoded.

#define MAX_EXP_IN_OBJ levels[settings.max_level]/(MAX_EXP_CAT - 1)

Because exp_obj sum to make the total score, we cannot allow that sum to exceed the maximum amount of experience a player can gain.

Thus we define MAX_EXP_IN_OBJ. It is important to try to make the value of MAX_EXP_CAT close to the actual number of experience objects in the game, otherwise the maximum level in any experience category could be quite low. To help the situation out a little I added 10 more levels, and jacked up the last level experience value. Its out of line with progression of previous levels, so if more levels are desired, this should be fixed. -b.t.

Definition at line 195 of file living.c.

#define MAX_EXPERIENCE levels[settings.max_level]

Since this is nowhere defined ...

Both come in handy at least in function add_exp()

Function Documentation

static void add_player_exp	(	object *	op,
		sint64	exp,
		const char *	skill_name,
		int	flag
	)		`[static]`

Add experience to a player - exp should only be positive.

Updates permanent exp for the skill we are adding to.

Parameters:

op	object we add exp to.
exp	experience to gain. Can be 0, but not that useful to call in that case...
skill_name	skill to add exp to. Can be NULL, in which case exp increases the players general total, but not any particular skill.
flag	what to do if the player doesn't have the skill. Combination of SK_EXP_xxx flags.

Here is the caller graph for this function:

void add_statbonus ( object * op )

Adds stat-bonuses given by the class which the player has chosen.

Parameters:

op	object which must be a player with contr not NULL.

Definition at line 863 of file living.c.

Referenced by key_change_class(), and key_roll_stat().

Here is the caller graph for this function:

int allowed_class ( const object * op )

Returns true if the given player is a legal class.

The function to add and remove class-bonuses to the stats doesn't check if the stat becomes negative, thus this function merely checks that all stats are 1 or more, and returns false otherwise.

Parameters:

op	object to check.

Returns:: 1 if allowed, 0 else.

Here is the caller graph for this function:

void apply_death_exp_penalty ( object * op )

Applies a death penalty experience, the size of this is defined by the settings death_penalty_percentage and death_penalty_levels, and by the amount of permenent experience, whichever gives the lowest loss.

Parameters:

op	victim of the penalty. Must not be NULL.

Here is the caller graph for this function:

void calc_perm_exp ( object * op )

Ensure that the permanent experience requirements in an exp object are met.

This really just checks 'op to make sure the perm_exp value is within proper range. Note that the checking of what is passed through has been reduced. Since there is now a proper field for perm_exp, this can now work on a much larger set of objects.

Parameters:

op	object to check.

Here is the caller graph for this function:

int change_abil	(	object *	op,
		object *	tmp
	)

Permanently alters an object's stats/flags based on another object.

Returns:: 1 if we sucessfully changed a stat, 0 if nothing was changed.

Note:: flag is set to 1 if we are applying the object, -1 if we are removing the object.; It is the calling functions responsibilty to check to see if the object can be applied or not. The main purpose of calling this function is the messages that are displayed - fix_object should really always be called after this when removing an object - that is because it is impossible to know if some object is the only source of an attacktype or spell attunement, so this function will clear the bits, but the player may still have some other object that gives them that ability.

Todo:: check logic, and things like that. Is the call to fix_object always required?

Here is the caller graph for this function:

void change_attr_value	(	living *	stats,
		int	attr,

	)

Like set_attr_value(), but instead the value (which can be negative) is added to the specified stat.

Parameters:

stats	item to modify. Must not be NULL.
attr	attribute to change.
value	delta (can be positive).

Todo:: check if attr is valid? Checks result valus is valid?

Here is the caller graph for this function:

void change_exp	(	object *	op,
		sint64	exp,
		const char *	skill_name,
		int	flag
	)

Changes experience to a player/monster.

This does bounds checking to make sure we don't overflow the max exp.

The exp passed is typically not modified much by this function - it is assumed the caller has modified the exp as needed. skill_name is the skill that should get the exp added. flag is what to do if player doesn't have the skill. these last two values are only used for players.

Parameters:

op	victim to alter.
exp	experience to gain (positive) or lose (negative).
skill_name	skill to change. Can be NULL.
flag	if experience gain, what to do if player doesn't have the skill if experience loss, whether to remove from all skills or only specified skill

It basically makes adjustments based on permanent exp and the like. This function should always be used for losing experience - the 'exp' value passed should be positive - this is the amount that should get subtract from the player.

Parameters:

op	object to which to substract.
exp	experience to lose.

Here is the caller graph for this function:

void share_exp	(	object *	op,
		sint64	exp,
		const char *	skill,
		int	flag
	)

Gives experience to a player/monster, sharing it with party if applicable.

This does bounds checking to make sure we don't overflow the max exp.

The exp passed is typically not modified much by this function - it is assumed the caller has modified the exp as needed.

This is merely a wrapper for change_exp().

Parameters:

op	victim to alter.
exp	experience to gain (positive) or lose (negative).
skill	skill to change. Can be NULL.
flag	if experience gain, what to do if player doesn't have the skill if experience loss, whether to remove from all skills or only specified skill

Note:: flag only applies to op, not other players in same party.

Here is the caller graph for this function:

static void subtract_player_exp	(	object *	op,
		sint64	exp,
		const char *	skill,
		int	flag
	)		`[static]`

Subtracts experience from player.

Eg, if we figure the player is losing 10% of his total exp, what happens is he loses 10% from all his skills. Note that if permanent exp is used, player may not in fact lose as much as listed. Eg, if player has gotten reduced to the point where everything is at the minimum perm exp, he would lose nothing.

Parameters:

op	victim we want to substract from
exp	value to substract. Should be positive.
skill	skill to substract exp from. Can be NULL.
flag	if SK_SUBTRACT_SKILL_EXP and skill is set, only subtract from the matching skill. Otherwise, this subtracts a portion from all skills the player has.

Todo:: check whether flag is necessary, can't it be only based on skill==null?

Charisma bonus.

Note:: 0.92.7 Changed way charisma works. Values now represent how much more it costs to buy something than to sell it (10, a value of 10 means it is that if it costs 50 gp to buy, you would only get 5 gp when you sell.) Let query_cost do the calculations on how to really do this. Buy keeping it this simple number, it is much easier to know how things will be influenced. A value of '1' means buying and selling is both the same value - any value less than or equal to 1 should not be used. At least as of now, the only place that uses this code is query_cost, in server/shop.c. This bonus is split evenly between buying and selling (ie, if the bonus is 2.0, then items are bought for 1.33 list, and sold at .667 This is figured by diff=(y-1)/(1+y), and for buy, it is 1+diff, for sell it is 1-diff

This no longer needs to be changed anytime the number of levels is increased - rather, did_make_save() will do the right thing and always use range within this table. for safety, savethrow should not be accessed directly anymore, and instead did_make_save() should be used instead.
