From 9442d178d287050bf9f3c42a520a5d85d6081e3e Mon Sep 17 00:00:00 2001 From: gepard1984 Date: Thu, 26 Jan 2012 15:55:42 +0000 Subject: * Modified drop system to allow overriding global item drop rates on per-item basis. For detailed explanation read source:trunk/db/mob_item_ratio.txt (topic:56118). * Added missing update to `logs.sql` (follow-up to r15519). git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@15521 54d463be-8e91-2dee-dedb-b68131a5f0ec --- src/map/mob.c | 79 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 78 insertions(+), 1 deletion(-) (limited to 'src/map/mob.c') diff --git a/src/map/mob.c b/src/map/mob.c index 123ae1c7f..f25c9ba8a 100644 --- a/src/map/mob.c +++ b/src/map/mob.c @@ -64,6 +64,14 @@ struct mob_db *mob_db(int index) { if (index < 0 || index > MAX_MOB_DB || mob_db struct mob_chat *mob_chat_db[MAX_MOB_CHAT+1]; struct mob_chat *mob_chat(short id) { if(id<=0 || id>MAX_MOB_CHAT || mob_chat_db[id]==NULL) return (struct mob_chat*)NULL; return mob_chat_db[id]; } +//Dynamic item drop ratio database for per-item drop ratio modifiers overriding global drop ratios. +#define MAX_ITEMRATIO_MOBS 10 +struct item_drop_ratio { + int drop_ratio; + int mob_id[MAX_ITEMRATIO_MOBS]; +}; +static struct item_drop_ratio *item_drop_ratio_db[MAX_ITEMDB]; + static struct eri *item_drop_ers; //For loot drops delay structures. static struct eri *item_drop_list_ers; @@ -3441,6 +3449,27 @@ static unsigned int mob_drop_adjust(int baserate, int rate_adjust, unsigned shor return (unsigned int)cap_value(rate,rate_min,rate_max); } +/** + * Check if global item drop rate is overriden for given item + * in db/mob_item_ratio.txt + * @param nameid ID of the item + * @param mob_id ID of the monster + * @param rate_adjust pointer to store ratio if found + */ +static void item_dropratio_adjust(int nameid, int mob_id, int *rate_adjust) +{ + int i; + if( item_drop_ratio_db[nameid] ) { + if( item_drop_ratio_db[nameid]->mob_id[0] ) { // only for listed mobs + ARR_FIND(0, MAX_ITEMRATIO_MOBS, i, item_drop_ratio_db[nameid]->mob_id[i] == mob_id); + if(i < MAX_ITEMRATIO_MOBS) // found + *rate_adjust = item_drop_ratio_db[nameid]->drop_ratio; + } + else // for all mobs + *rate_adjust = item_drop_ratio_db[nameid]->drop_ratio; + } +} + /*========================================== * processes one mobdb entry *------------------------------------------*/ @@ -3583,12 +3612,14 @@ static bool mob_parse_dbrow(char** str) // MVP Drops: MVP1id,MVP1per,MVP2id,MVP2per,MVP3id,MVP3per for(i = 0; i < 3; i++) { struct item_data *id; + int rate_adjust = battle_config.item_rate_mvp;; db->mvpitem[i].nameid = atoi(str[32+i*2]); if (!db->mvpitem[i].nameid) { db->mvpitem[i].p = 0; //No item.... continue; } - db->mvpitem[i].p = mob_drop_adjust(atoi(str[33+i*2]), battle_config.item_rate_mvp, battle_config.item_drop_mvp_min, battle_config.item_drop_mvp_max); + item_dropratio_adjust(db->mvpitem[i].nameid, class_, &rate_adjust); + db->mvpitem[i].p = mob_drop_adjust(atoi(str[33+i*2]), rate_adjust, battle_config.item_drop_mvp_min, battle_config.item_drop_mvp_max); //calculate and store Max available drop chance of the MVP item if (db->mvpitem[i].p) { @@ -3650,6 +3681,7 @@ static bool mob_parse_dbrow(char** str) ratemax = battle_config.item_drop_common_max; break; } + item_dropratio_adjust(id->nameid, class_, &rate_adjust); db->dropitem[i].p = mob_drop_adjust(rate, rate_adjust, ratemin, ratemax); //calculate and store Max available drop chance of the item @@ -4384,11 +4416,40 @@ static bool mob_readdb_race2(char* fields[], int columns, int current) return true; } +/** + * Read mob_item_ratio.txt + */ +static bool mob_readdb_itemratio(char* str[], int columns, int current) +{ + int nameid, ratio, i; + struct item_data *id; + + nameid = atoi(str[0]); + + if( ( id = itemdb_exists(nameid) ) == NULL ) + { + ShowWarning("itemdb_read_itemratio: Invalid item id %d.\n", nameid); + return false; + } + + ratio = atoi(str[1]); + + if(item_drop_ratio_db[nameid] == NULL) + item_drop_ratio_db[nameid] = (struct item_drop_ratio*)aCalloc(1, sizeof(struct item_drop_ratio)); + + item_drop_ratio_db[nameid]->drop_ratio = ratio; + for(i = 0; i < columns-2; i++) + item_drop_ratio_db[nameid]->mob_id[i] = atoi(str[i+2]); + + return true; +} + /** * read all mob-related databases */ static void mob_load(void) { + sv_readdb(db_path, "mob_item_ratio.txt", ',', 2, 2+MAX_ITEMRATIO_MOBS, -1, &mob_readdb_itemratio); // must be read before mobdb if (db_use_sqldbs) { mob_read_sqldb(); @@ -4417,6 +4478,14 @@ void mob_reload(void) mob_db_data[i]->maxskill=0; } + // Clear item_drop_ratio_db + for (i = 0; i < MAX_ITEMDB; i++) { + if (item_drop_ratio_db[i]) { + aFree(item_drop_ratio_db[i]); + item_drop_ratio_db[i] = NULL; + } + } + mob_load(); } @@ -4481,6 +4550,14 @@ int do_final_mob(void) mob_chat_db[i] = NULL; } } + for (i = 0; i <= MAX_ITEMDB; i++) + { + if (item_drop_ratio_db[i] != NULL) + { + aFree(item_drop_ratio_db[i]); + item_drop_ratio_db[i] = NULL; + } + } ers_destroy(item_drop_ers); ers_destroy(item_drop_list_ers); return 0; -- cgit v1.2.3-60-g2f50
