Been looking into how to Make mobs spawn pretty quickly after being killed for pits.

Sooo, in the config file there will be a number for death time. When an npc dies, this is the amount of time before the server will remove the npc entirely from a spawn. For the server to spawn a new mob, it needs the npc to be removed entirely before it can spawn another one. So this is the easiest way to change that.

Digging deeper into it. The game server should have a main loop that it repeats as long as it is running. Something like this.

*note, code is C#

public void MainLoop()
   while (true)
       NpcProcess(); //handles npc actions
       PlayerProcess(); //handles player actions
       TimerProcess(); //handles all timed processes such as hp/mp/sp regen
       Thread.Sleep(100); //(milliseconds)

This loop will happen as fast as it can process those methods and then sleep for 100 millisecond before repeating. So in theory, the fastest you could respawn a mob after it dies is just over 100 millseconds.

However, in the npc process method you might have a spawn timer that gets checked before it will try and spawn missing mobs. The Helbreath Champions project will only let the server respawn mobs every 3 seconds. This could be a bottle neck to check for faster respawns.

Another bottle neck is in how many mobs the server will spawn at once. In the Helbreath Champions project it is limited to 1.
 if (CreateNpc(spawn.NpcName, spawn.Zone.GetRandomLocation(), spawnID))spawn.Count++;                                   
continue; // only one npc should spawn in each spawn location per iteration

This means that every 3 seconds, the server will check if mobs are missing from spawns. Then spawn only 1 mob and wait another 3 second, this repeats until the pit is filled. To allow all missing mobs from a pit to respawn at once, just have it create as many mobs that are missing from the total allowed.

Hope that helped some! Good luck
