From c6b0361bd56ee72df8b9b3ee7eca824e0619d407 Mon Sep 17 00:00:00 2001 From: skotlex Date: Thu, 21 Feb 2008 10:36:26 +0000 Subject: - Added status_calc_life to properly calculate hp/max_hp as a ratio taking into accounts overflows (and for now also avoids divisions by 0). Applied this function around clif.c, mob.c and pet.c - Implemented the correct walk-speed bonus from the Bard/Dancer spirit. - Added a few error messages in case something goes wrong in the new auth db system. - Fixed logarithmic drops turning 0% drop rates into 100%. git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@12225 54d463be-8e91-2dee-dedb-b68131a5f0ec --- src/map/mob.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) (limited to 'src/map/mob.c') diff --git a/src/map/mob.c b/src/map/mob.c index e66a980a3..2725f0b39 100644 --- a/src/map/mob.c +++ b/src/map/mob.c @@ -2451,7 +2451,7 @@ int mob_class_change (struct mob_data *md, int class_) if (md->class_ == class_) return 0; //Nothing to change. - hp_rate = md->status.hp*100/md->status.max_hp; + hp_rate = status_calc_life(md->status.hp, md->status.max_hp); md->class_ = class_; md->db = mob_db(class_); if (battle_config.override_mob_names==1) @@ -2586,7 +2586,7 @@ int mob_summonslave(struct mob_data *md2,int *value,int amount,int skill_id) if (!battle_config.monster_class_change_recover && (skill_id == NPC_TRANSFORMATION || skill_id == NPC_METAMORPHOSIS)) - hp_rate = 100*md2->status.hp/md2->status.max_hp; + hp_rate = status_calc_life(md2->status.hp, md2->status.max_hp); for(;kbl,bl,BCT_ENEMY)>0) return 0; - rate = 100*status_get_hp(bl)/status_get_max_hp(bl); + rate = status_calc_life(status_get_hp(bl), status_get_max_hp(bl)); if (rate >= min_rate && rate <= max_rate) (*fr) = bl; @@ -2717,7 +2717,7 @@ struct block_list *mob_getmasterhpltmaxrate(struct mob_data *md,int rate) { if (md && md->master_id > 0) { struct block_list *bl = map_id2bl(md->master_id); - if (status_get_hp(bl) < status_get_max_hp(bl) * rate / 100) + if (bl && status_calc_life(status_get_hp(bl), status_get_max_hp(bl)) < rate); return bl; } @@ -2823,11 +2823,11 @@ int mobskill_use(struct mob_data *md, unsigned int tick, int event) case MSC_ALWAYS: flag = 1; break; case MSC_MYHPLTMAXRATE: // HP< maxhp% - flag = 100*md->status.hp/md->status.max_hp; + flag = status_calc_life(md->status.hp, md->status.max_hp); flag = (flag <= c2); break; case MSC_MYHPINRATE: - flag = 100*md->status.hp/md->status.max_hp; + flag = status_calc_life(md->status.hp, md->status.max_hp); flag = (flag >= c2 && flag <= ms[i].val[0]); break; case MSC_MYSTATUSON: // status[num] on @@ -3282,7 +3282,7 @@ static unsigned int mob_drop_adjust(int baserate, int rate_adjust, unsigned shor { double rate = baserate; - if (battle_config.logarithmic_drops && rate_adjust > 0) //Logarithmic drops equation by Ishizu-Chan + if (battle_config.logarithmic_drops && rate_adjust > 0 && baserate > 0) //Logarithmic drops equation by Ishizu-Chan //Equation: Droprate(x,y) = x * (5 - log(x)) ^ (ln(y) / ln(5)) //x is the normal Droprate, y is the Modificator. rate = rate * pow((5.0 - log10(rate)), (log(rate_adjust/100.) / log(5.0))) + 0.5; -- cgit v1.2.3-70-g09d2
