How many forms can safely be added to a Form List via script?

[gigantibyte]

Basic question I can't seem to find an answer for in the geck wiki. Would 2000 forms fit in a form list?

I don't know of any limit, though obviously there is one. It's probably the value of a signed integer, so over 2 million forms. 2000 should be fine.

Thank you kindly. I was worried it was something small, like 256.

Well, there's a form list called "Everything" that holds over 1500 forms, so it's at least that high.

Speaking of form lists, what happens if my mod adds another mod's form to a list via a script, then the player removes the mod the form was from? Will my mod's list be updated automatically, moving up all forms that were listed below it? Or will a "ghost" of the form still exist, causing the game to crash if it is called, or something more mundane like having a false item count?

When a mod is unloaded, all references to its forms are removed, so moving index-wise down (toward 0) any still present forms above it.

 

Although, I've noticed bad forms being returned from an FL during the first few seconds (only) after game load, which may or may not be related.

If the edit to a form list is made with ListAddForm, which is an NVSE function, then nothing bad will happen if a mod is removed. ListAddItem works ONLY on the in-memory list, and does not save with the save game data.

 

AddFormToFormList however, which is a vanilla function, DOES save to the save game, and will cause issues upon removing a mod. You should ALWAYS use NVSE for editing form lists. Keep in mind that doing so will require you to make the edit every time the game is restarted, which is easily done by having a quest script running with the GetGameLoaded function checking first.
