Frostfall Spell Monitor Optimized

Will work mid-playthrough. Be sure to read installation instructions to ensure no issues when installing.

How it works

This mods simply converts the script's `OnMagicEffectApply` to po3's `OnMagicEffectApplyEx` so Frostfall's spell monitor will only fire if the player is hit with a frost or fire effect.

Old Script:

Event OnMagicEffectApply(ObjectReference akCaster, MagicEffect akEffect)

// stuff here

New Script:

import PO3_Events_Alias

Event OnInit()

RegisterForMagicEffectApplyEx(self as ReferenceAlias, MagicDamageFire as Form, True)

RegisterForMagicEffectApplyEx(self as ReferenceAlias, MagicDamageFrost as Form, True)

Event OnMagicEffectApplyEx(ObjectReference akCaster, MagicEffect akEffect, Form akSource, bool abApplied)

// Same stuff

How this improves performance

TLDR: Reduces Frostfall script lag that occurs when hit with many magic effects at once.

Long version: Skyrim vanilla `OnMagicEffectApply` event will fire for every magic effect that is applied.

In this script, that is every magic effect applied to the player. With a heavy load order like mine, this resulted in lots of magic effects hitting the player at once, causing script lag and eventually stack dumps. This mod replaces that event with po3's `OnMagicEffectApplyEx`, which only fires for magic effects/keywords you explicitly register it for. The original script only wants to handle fire and frost effects "MagicDamageFire" and "MagicDamageFrost", so this script registers for just those two keywords. All other magic effects that hit the player will no longer run this event, reducing script lag. The amount of script lag that is reduced will depend on how many magic effects are hitting the player at one time. The more effects the player is hit with, the more performance is saved with this mod.

Installation

New game:

Install with any mod manager of choice. Just make sure this overwrites Frostfall's script.

Mid-save (where Frostfall is already active):

To be sure this doesn't break anyone's game, do the following

1. Load up your game

2. Go to a low-activity cell using console commands. I use  "coc QASmoke" personally. This is to ensure the old script isn't actively doing any work when it's swapped out just in case (It IS Skyrim after all)

3. Save game

4. Install this mod with any mod mana
