Function Documentation

sint64 add_exp	(	object *	op,
		sint64	exp,
		int	skill_nr,
		int	exact
	)

Add experience to player.

Parameters:

op	The player.
exp	How much experience to add (or, in case the value being negative, subtract).
skill_nr	Skill ID.
exact	If 1, experience gained will not be capped.

Returns:

0 on failure, experience gained on success.

Definition at line 298 of file exp.c.

sint64 adjust_exp	(	object *	pl,
		object *	op,
		sint64	exp
	)

Make sure that we don't exceed max or min set on experience.

This function also adjusts skill category experience, and overall player experience based on the skill category that has the most experience.

Parameters:

pl	Player.
op	Skill object.
exp	Experience.

Returns:

0 on failure, experience we added otherwise.

Definition at line 567 of file exp.c.

void apply_death_exp_penalty

(

object *

op

)

Applies death experience penalty.

We never lose a level, just percent of the experience we gained for the next level.

Parameters:

op	Victim of the penalty. Must not be NULL.

Definition at line 637 of file exp.c.

float calc_level_difference	(	int	who_lvl,
		int	op_lvl
	)

Calculate level difference.

We will get a bonus or malus value here, unless both levels match.

Yellow does not always mean same level, but in equal range.

Experience multiplication based on target color range:

• yellow: Between 0.8 and 1.1 (80% - 110%).
• blue: Between 0.4 and 0.6 (40% - 60%).
• green: Between 0.25 and 0.3 (25% - 30%).
• orange: Between 1.2 and 1.4 (120% - 140%).
• red, purple: 1.4 + 0.1% per level.

If the target is in yellow range, the experience multiplication is between 0.8 and 1.1 (80% - 110%).

If the target is in blue range, the experience

Parameters:

who_lvl	Player.
op_lvl	Victim.

Returns:

Level difference.

uint64 calculate_total_exp

(

object *

op

)

Calculate total experience of player, based on all skills they know.

Parameters:

op

Player.

Returns:

The total experience.

Definition at line 838 of file exp.c.

uint64 level_exp	(	int	level,
		double	expmul
	)

Calculates how much experience is needed for a player to become the given level.

Parameters:

level	Level to become.
expmul	Experience multiplicator.

Returns:

The experience needed.

Todo:

Remove, since the param expmul seems to always be passed as '1.0'?

Definition at line 285 of file exp.c.

void player_lvl_adj	(	object *	who,
		object *	op
	)

For the new experience system. We are concerned with whether the player gets more hp, sp and new levels.

Will tell the player about changed levels.
