Monster spawns, is it random?

[robby22]

Do monsters just randomly respawn on some tile after they are killed? and if not I'd like to know how to figure out the most active areas in the map. Which files tell us how monster spawns work?

Edit: I'm reading this https://github.com/rathena/rathena/blob/c6470ff4ff82fe30c98e00344beda667ae80ed44/npc/pre-re/mobs/dungeons/ra_san.txt

doesn't say what those coordinates mean.

ra_san01,0,0 monster Isilla 1772,10  // the green color set to 0 . 0 = random map spawn

ra_san01,61,141,58,98 monster Vanberk 1771,20,300000 // in this case it spawn in the are of ra_san01 61,141
