npc_parse_mob map random

[misterM]

Hello folks I was wanting to add more maps in the parse of mob, I even got it though he does the random only once, I always wanted the monster to appear he does a random of maps.

Here is the code below the modified part, I think it's because the txt file is read only once, could anyone help me how can I make the maps stay random?

static const char* npc_parse_mob(char* w1, char* w2, char* w3, char* w4, const char* start, const char* buffer, const char* filepath)
{
	int num, class_, i, j, mob_lv = -1, ai = -1, size = -1, w1count;
	short m,x,y,xs = -1, ys = -1;
	char mobname[NAME_LENGTH];
	struct spawn_data mob, *data;
	struct mob_db* db;
	int mp;
	

	memset(&mob, 0, sizeof(struct spawn_data));

	mob.state.boss = !strcmpi(w2,"boss_monster");

	// w1=<map name>,<x>,<y>{,<xs>{,<ys>}}
	// w3=<mob name>{,<mob level>}
	// w4=<mob id>,<amount>{,<delay1>{,<delay2>{,<event>{,<mob size>{,<mob ai>}}}}}
	if( ( w1count = sscanf(w1, "%15[^,],%15[^,],%15[^,],%6hd,%6hd,%6hd,%6hd", mob.parse[0].map, mob.parse[1].map, mob.parse[2].map, &x, &y, &xs, &ys) ) < 3
	||	sscanf(w3, "%23[^,],%11d", mobname, &mob_lv) < 1
	||	sscanf(w4, "%11d,%11d,%11u,%11u,%77[^,],%11d,%11d[^\t\r\n]", &class_, &num, &mob.delay1, &mob.delay2, mob.eventname, &size, &ai) < 2 )
	{
		ShowError("npc_parse_mob: Invalid mob definition in file '%s', line '%d'.\n * w1=%s\n * w2=%s\n * w3=%s\n * w4=%s\n", filepath, strline(buffer,start-buffer), w1, w2, w3, w4);
		return strchr(start,'\n');// skip and continue
	}
	if( mapindex_name2id(mob.parse[0].map) == 0 || mapindex_name2id(mob.parse[1].map) == 0 || mapindex_name2id(mob.parse[2].map) == 0)
	{
		ShowError("npc_parse_mob: Unknown map1 '%s', map2 '%s', map3 '%s' in file '%s', line '%d'.\n", mob.parse[0].map, mob.parse[2].map, mob.parse[3].map, filepath, strline(buffer,start-buffer));
		return strchr(start,'\n');// skip and continue
	}
	for(mp = 0; mp < 4; mp++) {
		m =  map_mapname2mapid(mob.parse[mp].map);
		if( m < 0 )//Not loaded on this map-server instance.
			return strchr(start,'\n');// skip and continue
	}
	
	mob.m = (unsigned short)m;
