Fallout 2287 - Nuclear Winter - NPC Patch

The problem:

When other mods spawn more NPCs, Nuclear Winter adds breath shaders to each NPC via Spell. Over time, a large number of NPCs with active spells accumulate, which are activated under certain circumstances, even if the player is not in the cell of the NPC. This leads over time to higher and higher system load, which can eventually lead to CTDs and other problems (e.g. suspended stacks). Especially mods like Mutant Menagerie, which spawn massive amounts of NPCs, put a lot of load on the system. (For me it was sometimes up to 5000 active scripts.) CTDs can accumulate. Script latency occurs more and more often.

This mod removes these spells when the player is not in the same cell as the NPCs. The system load is thereby significantly reduced.

How it Works (Technically):

Every NPC gets the spell 'Winter_NPC_CloakEquip' at some point. This activates the magicEffect 'Winter_NPC_CloakEquipEffect', which in turn

starts the script 'cloakshader'.

Which in turn registers the event with 'RegisterForRemoteEvent(NPC,

"OnLocationChange")'.

In the course of time more and more NPCs accumulate, which listen to

this event. In my case there are thousands by now.

Since neither the Spell nor the Magic Effect is cleared, they all wait

for the event, which comes when certain conditions are met.

For example, if I travel to Homeplate and no other NPC is loaded and

then wait or sleep, the event is triggered.

This then causes hundreds or even thousands of simultaneous events,

other important scripts are then put on the stack. It comes then again

and again to CTDs, especially when I am e.g. in SS2 settlements. Script

Although the unregister is provided, in the event ' OnEffectFinish', but

this event is never triggered. Since the Spell on the NPC is not

deleted and the MagicEffect is therefore always active. Every NPC that

got the Spell, so every NPC that was already 3d loaded, has the active

MagicEffect with the registered remote event. At the beginning this

might not be a problem, but in the course of time countless NPCs

accumulate, which wait for the remote event to become active at once and

collapse the system.

The Solution:

A small change to the CloakShader script will fix the problem:

Event Actor. OnLocationChange(Actor akNPC, Location akOldLoc,

Location akNewLoc)

;---------------------------------------------------

Utility. Wait(Utility. RandomFloat(0. 0, 1. 0))

If !NPC. Is3DLoaded()

NPC. RemoveSpell(Winter_NPC_CloakEquip)

UnRegisterForRemoteEvent(NPC, "OnLocationChange") ; probably

not necessary, since unregister comes with remove spell.
