Are there SKSE papyrus functions that would allow me to get and set the condition of a weapon or piece of armor? What I mean by "condition" is, when you upgrade your equipment at a grindstone or armor bench, it modifies the item's condition to be greater than 100% - I want to be able to access the variable that determines this.

I'm also looking for an event that fires when an NPC is hit, which can tell me how much damage was done. I'm guessing ObjectReference-&--#62;OnHit() would work, but as far as I can tell it doesn't show how much damage was dealt by the hit.

Also, is there a way to have a script apply to every object of a certain type in the game, without modifying each and every object?

I'm trying to make a mod which will have weapons and armor degrade as they're used, requiring the player to repair their gear (in exacly the same way that they upgrade them now). I would like this to apply to all gear in the game, but I would be satisfied if it only applied to the player's gear, though it must be independant of what that gear is.

I don't think so. If you want to find out what functions are added by SKSE you can always open the PSC files in src\skse\scripts\modified with notepad and have a look. Also, this http://www.gamesas.com/topic/1412880-weapon-degradation-any-one-working-on-it/ may interest you.

There isn't one, I've requested the same functions in the past.

The only way to tell is to poll the actor's health several times per second and compare the actor value health to the health saved from the last update. It actually works fine but for NPCs, you should of course stop updating if they're far from the player.

For what you want to do, you should only need to have a script attached to actors using the weapons/armor. But if you find it necessary to attach a script to the object, I think the answer is no. I'm not sure why you would need to though.

Sorry, allow me to rephrase. I want the script to apply to every actor, not every item. The script itself would dig into the actor's equipment in order to modify the condition of the appropriate item, but it has to be completely independent of which items are equipped.

It's sad that the functions to modify condition don't exist, though... Do you know if they will in a future version of SKSE?
