[HELP!] What are the Value's in this LUA?

[Creepfold]

function Nightshroud_CheckA(Unit)
if Unit:GetHealthPct() < 75 then
Unit:CastSpell(37669)
Unit:SendChatMessage(12, 0, "Voidwalkers, come to me!")
Unit:SpawnCreature(100245, 4249, -4136, 939, 0.5, 21, 360000);
Unit:SpawnCreature(100245, 4259, -4132, 938, 1.22, 21, 360000);
Unit:SpawnCreature(100245, 4264, -4147, 940, 1.5, 21, 360000);
end
end


or however, how does the unit spawn thing work? this piece of LUA is taken from Gastricpenguin , but what are the things?
what should i edit so the creature spawns out of his corpse?
What i know:
Unit:SpawnCreature(Entryid, 4264, -4147, 940, 1.5, 21, Despawningtime);
Unit:SpawnCreature(100245, 4264, -4147, 940, 1.5, 21, 360000);

but what should i add in the other 4 spots? thanks if you can help me:P

function phaase_44(pUnit, Event)
if pUnit:GetHealthPct() < 30 then
pUnit:RemoveEvents();
pUnit:SendChatMessage (11, 0, "Come my Dark Warriors!! Battle Await us!")
pUnit:SpawnCreature(400002, 366.904205, -100.372467, 32.493214, 1.551133, 67, 220000);
pUnit:SpawnCreature(400001, 382.689728, -99.689819, 32.487904, 1.45258, 67, 220000);
pUnit:SpawnCreature(400000, 373.877197, -105.883064, 34.643391, 1.519717, 67, 220000);
pUnit:SpawnCreature(400003, 374.174347, -95.544601, 32.495548, 1.531497, 67, 220000);
pUnit:RegisterEvent("phaase_55",1000, 0)
end
end

This is how a summoning should be
