EQEmulator Forums - Question about quest code

Below is the code for Terris Thule in nightmareb, can someone explain to me what is going on on the death event and the timer event? I read the wiki but woudn't figure these two out exactly.

Also on a side note, is there a way to keep an npc from running at low health and how exactly do i make them kos. I tried Georges tool to make an npc kos faction but i still con indiff with or w/o the gm flag on. thx

Code:



sub EVENT_SPAWN {



quest::setnexthpevent(75);



quest::settimer(1,1);



}







sub EVENT_HP {



        if($hpevent == 75)



                {



                quest::spawn2(221006,0,0,-1858,-25,134,5);



                quest::spawn2(221006,0,0,-1780,-59,134,193); 



                quest::spawn2(221006,0,0,-1833,102,134,165);



                quest::spawn2(221006,0,0,-1852,48,134,157);



                quest::spawn2(221006,0,0,-1876,-63,134,228);







                quest::spawn2(221006,0,0,-1933,49,134,156); 



                quest::spawn2(221006,0,0,-1984,-61,134,148);







                quest::spawn2(221006,0,0,-1896,-108,134,230); 



                quest::spawn2(221006,0,0,-1899,-65,134,243);                                                              



                       quest::spawn2(221006,0,0,-1732,3,134,190);

                }







        if($hpevent == 50) {
