I want to make a spell that creates a swarm of insects in a 30 foot radius around the caster, and basically prevents anyone else from using magic within the area. I have no idea how to do either of these things.

The silence effect I think there might be something for, as I think there is a silence illusion spell.

Here's what I've got so far with the swarm spell:

Scriptname DnDSwarmCurseScript extends activemagiceffect  import Critterimport Utilityint property iMaxCritterCount autoint property iCurrentCritterCount autoFormList Property CritterTypes autoActivator Property DnDSwarmBug autoint property fMaxPLayerDistance autoevent OnEffectStart(Actor akTarget, Actor akCaster); How many do we need to spawn?int icrittersToSpawn = iMaxCritterCount; Create that many crittersint i = 0;while (i < icrittersToSpawn); Create one critter at a time;SpawnCritteratRef(akCaster as ObjectReference)ObjectReference critterRef = akCaster.PlaceAtMe(Game.GetForm(0x020048AD), 1, false, false); Wait a bit before the next spawn;Wait(fFastSpawnInterval); Nexti = i + 1endWhileDebug.MessageBox("generation complete")endEvent; Spawns one Critter at a specific locationFunction SpawnCritterAtRef(ObjectReference arSpawnRef); Pick a random critter typeActivator critterType = CritterTypes.GetAt(RandomInt(0, CritterTypes.GetSize() - 1)) as Activator; Create the critter and cast it to the critter base classObjectReference critterRef = arSpawnRef.PlaceAtMe(critterType, 1, true, false);Critter thecritter = critterRef as Critter; Set initial variables on the critter; ;  Debug.TraceConditional("Spawner " + self + " is creating Critter " + thecritter, bPrintDebug);endFunction

Its some manipulated gamesas code. Unfortunately, I it doesn't seem to actually do anything in game. I've no idea why...
Maybe one of you can spot my error?

At first glance I think it is your PlaceAtMe function. The last parameter you have set to true which is telling it to set the object to disabled. Try either setting that parameter to false or have your script enable the critter at some point.

Thanks, but that didn't seem to do it. Setting it to false made no visible difference, although it is helpful in the long run.

Okay, I got this working, but it just makes a bee wherever the player is. Can I make it such that the bees start moving randomly very fast whenever they load?

I figured it out, on the bee themselves I added this script:

Scriptname DnDBeeSwarmingScript extends ObjectReference int Property duration autoevent OnLoad()   int i = 0   int randomx = 0   int randomy = 0   int randomz = 0while i < duration   randomx = Utility.RandomInt(-50, 50)   randomy = Utility.RandomInt(-50, 50)   randomz = Utility.RandomInt(-50, 50)   randomx = randomx + self.GetPositionX() as int   randomy = randomy + self.GetPositionY() as int   randomz = randomz + self.GetPositionZ() as int   self.SplineTranslateTo(randomX, randomY, randomZ, 0, 0, 0, 5, 350)   Utility.Wait(1)   i = i + 1endwhileSelf.disable()endEvent
