How do I add a mob spawner to my map?

[Divided2]

I'm working on this grave yard map for my mod with Michael Jackson as the boss fight coming out of a grave along with other enemies, I've already figured that part out, now I'm trying to add a mob spawner to my map, how could I do this? And could it be done with Slade?

If you are using GZDoom then you could make an actor that works similar to the BossCube that summons the monsters for the ICon of Sin.

An easy way to do this is when you create holes in the sector floor with the same TID

and stuff them with monsters. Then with a walkover trigger, for example, push those

monsters up ready to attack. As was done in 4 seasons of DOOM (Seasons.zip) MAP01.

Or, since it is a boss you could recreate the Icon of Sin monster spawner,

of course, with a port like GZDoom (etal) you could have more control what

is spawned and how with scripts or creating a specific actors.

Let me add on a clarification as this question bothered me 2 minutes ago and my prior answer was very lackluster.

 

1. A Monster Spawner works different than a RandomSpawner, but can still act like a Randomspawer too.
2. The basic build for a MOnster Spawner depends on if you want to be a visible object or an invisible object just to summon monsters
3. I'll assume you want an invisible spawner

Actor MonsterSpawnerDude 5454// The Code to place the Spawner in your map as object
{
   // There are no properties because this spawner is an invisible actor placed to achieve a single goal.
  States
    {
       Spawn:
            TNT1 A 35 /One second cool down time

			SUmmon:
					TNT1 A 0 A_Jump(128, "DoomIMPcall")
					TNT1 A 0 A_Jump(128, "DemonCaller")
					TNT1 A 0 A_Jump(128, "HallKnight")
					Loop
			DOOMIMPCall:
					TNT1 A 0 A_SpawnItem("DoomImp")
					Goto SPawn
			DemonCaller:
					TNT1 A 0 A_SpawnItem("Demon")
					Goto Spawn
			HallKNight:
					TNT1 A 0 A_SpawnItem("HellKNight")
					Goto Spawn
}
}
