I'd like to create an item that, when worn, a players stat is automatically minused a percentage amount. Is this possible? I couldn't find any Ench/Alch effects that do this. Though similar to poison except, not over time. I'd like it to be an instant loss. 50% - or 25% and of a stat I can change.

This can be done through math in a script. It consists of subtracting the actor values and multiplying them by a percentage.

Try using either .GetBaseAV() or .GetAV() (this accounts for buffs and debuffs)

An example for getting a percentage though damageAV

float property percentage auto;I used 0.2 (20%)akTarget.damageAV("health", (akTarget.GetAV("health") - (akTarget.GetAV("health") * percentage))

It just an example on how to go about using math this way.

"Better" math:

akTarget.damageAV("health", (akTarget.GetAV("health") * (1.0 - percentage))

Thanks for chiming in guy - much appreciated.

So this something I can make a script out of and add to an item? [sorry I'm not very knowledgeable in scripting - or math for that matter]

Looking at the Ring of Namira as an example [since that's the only one I know of off hand]

ScriptName DA11RingofNamiraScript extends ObjectReferencePerk Property DA11Cannibalism  Auto  Event OnEquipped(Actor akActor)If akActor == Game.GetPlayer()Game.GetPlayer().AddPerk(DA11Cannibalism )EndIfEndEventEvent OnUnequipped(Actor akActor)If akActor == Game.GetPlayer()Game.GetPlayer().RemovePerk(DA11Cannibalism )EndIfEndEvent

It has the OnEquipped / Unequipped function so the percentage would only apply if the item is worn and subsequently removed if the item is taken off. It uses a Perk though - should I first set this up as a perk or just write it all into a script?

There's different ways to do this but doing it like the Ring of Namira will work too.

You need to add a new script to the item you have created, something like this:

ScriptName YourScript extends ObjectReferenceEvent OnEquipped(Actor akActor)  If akActor == Game.GetPlayer()    akActor.damageAV("health", (akActor.GetAV("health") * (1.0 - 0.2))  EndIfEndEventEvent OnUnequipped(Actor akActor)  If akActor == Game.GetPlayer()    akActor.damageAV("health", (akActor.GetAV("health") * (1.0 + 0.2))  EndIfEndEvent

To be honest a much better approach in my opinion would be to enchant your item. Make a new magic effect that lowers health, then a new enchantment using the magic effect you just created.
Look on http://www.creationkit.com/Enchantment & http://www.creationkit.com/Magic_Effect for more information.

Thanks for the help dudster.

I got the script working but I think the function is off. It takes a percentage of health away when you put it on and take it off - it doesn't reduce the players total health by a percentage. Sorry if I didn't explain it right. When the player wears the item, their total health is reduced by a percentage while wearing it. Say 50% for this. If I have 100max health and I put on this item, my max health is now 50. When I take the item off, My max health is back to 100.

Originally I just added an AbDamageHealth with a fixed magnitude but I want the effect to scale - hence, using percentage of total health rather than a fixed value.

Do you want it to take for instance 50% off everytime you put it on but never "give back" the health? Eg, the health would go to 50, then 25 next time you equip it, then 12.5 after that?
If so you would just remove the whole OnUnEquipped event.

Definitely get it back OnUnequipped.

Here's what I've been playing with but it's not quite working out - I'm actually swapping 50% health into Magicka - so whatever the total is for the 50% of the health, the players magicka is raised by that amount.

Scriptname blahblahSCR extends ObjectReferenceEvent OnEquipped(Actor akActor)If akActor == Game.GetPlayer()  akActor.ForceAV("health", (akActor.GetBaseActorValue("health") * (1.0 - 0.5) ))  akActor.ForceAV("magicka", (akActor.GetBaseActorValue("health") * (1.0 + 0.5) ))EndIfEndEventEvent OnUnequipped(Actor akActor)If akActor == Game.GetPlayer()  akActor.ForceAV("health", (akActor.GetBaseActorValue("health") * (1.0) ))  akActor.ForceAV("magicka", (akActor.GetBaseActorValue("health") * (1.0) ))EndIfEndEvent

I'm trying to get it to get the value it took away from the health [the 50% from the base 100%] and convert that number over to magicka. As an example - If I have 100 Health and 200 Magicka - I lose 50% health = 50points and my magicka is raised by 50points. OnUnequipped - I get back my 50% health [50points] and lose that value from the Magicka.

The code above is janky - I'm not getting the % from health into the magicka, I'm manually saying take 50% and that's not right.

you're multiplying by 1.0 in the OnUnEquiped event - that just sets the value to what it is already at.

Better is * 1 / (1.0 - 0.5) which would multiply by 2, reversing the 50%

Better yet would be to set quest to go with the item and record the number removed so you can add it back. Otherwise you're calculations get affected by other modifications to the same stat

[edit]

... or use a property on the script, I suppose. that would be simpler.

The OnUnequipped works for now - it sets the value back to what it was. What I'd like to be able to do is get the point value that was removed from the health and add it to the magicka. I'm struggling with that part the most.

How about:

Scriptname blahblahSCR extends ObjectReferenceint loss = 0float percent = .2    ; percent to loseEvent OnEquipped(Actor akActor)    If akActor != Game.GetPlayer()        return    EndIf        int health = akActor.GetBaseActorValue("health")    loss = health * (1.0 - percent)    akActor.ForceAV("health", -loss)    akActor.ForceAV("magicka", loss)EndEventEvent OnUnequipped(Actor akActor)    If akActor != Game.GetPlayer()        return    EndIf    akActor.ForceAV("health", loss)    akActor.ForceAV("magicka", -loss)EndEvent

Make a magic effect for health, and in the spell, assign it a negative value (Say, -5HP) Then attach a script to your item that casts that on the player enough times to reduce his health to the percentage you want, and have a script in the effect that removes it when the item is taken off.

Magic effects can remove stat points, but there is no way I know of to set the magnitude based on the players' max health.

Thanks for taking the time to write that out. Unfortunately it wont compile and I'm not skilled enough in papyrus to understand why.

Well the first thing I notice is, you can't assign a float value to .2 - you have to use 0.2

I tried 0.2. Still wouldnt compile.

this is what I get after i deal with the float and change that to 0.2.


blahblahSCR.psc(11,8): type mismatch while assigning to a int (cast missing or types unrelated)
blahblahSCR.psc(12,4): type mismatch while assigning to a int (cast missing or types unrelated)

11 is int health = akActor.GetBaseActorValue("health")
12 is loss = health * (1.0 - percent)

try making 'int health' 'float health'

Not sure if this will fix it but you can try ModAV instead, also I would include a variable to remember how much health gets taken when the object is equipped (I put in Int healthMod) so you can give back the same amount when it gets unequipped

Scriptname blahblahSCR extends ObjectReferenceFloat healthModEvent OnEquipped(Actor akActor)	If akActor == Game.GetPlayer()		healthMod = akActor.GetBaseActorValue("health") * 0.5				akActor.ModAv("health", -healthMod)		akActor.ModAv("magicka", healthMod)	EndIfEndEventEvent OnUnequipped(Actor akActor)	If akActor == Game.GetPlayer()		akActor.ModAv("health", healthMod)		akActor.ModAv("magicka", -healthMod)	EndIfEndEvent

What do you mean by this?

Edit: messed up the signs for the adding and removing stats

Thanks Xtynct. It compiled with the following:

Scriptname blahblahSCR extends ObjectReference float loss = 0.0float percent = 0.2    ; percent to loseEvent OnEquipped(Actor akActor)    If akActor != Game.GetPlayer()	    return    EndIf   float health = akActor.GetBaseActorValue("health") as int    loss = health * (1.0 - percent)    akActor.ForceAV("health", -loss)    akActor.ForceAV("magicka", loss)EndEventEvent OnUnequipped(Actor akActor)    If akActor != Game.GetPlayer()	    return    EndIf    akActor.ForceAV("health", loss)    akActor.ForceAV("magicka", -loss)EndEvent

But when I test and put the item on it just kills me instantly.

lol.

You dont need 'as int' if its a float

That would make loss = to 80% of your health

That would set your health to -80% of your health (80% UNDER dead, which is why you die instantly)

Brilliant Xtynct! Your's worked! I only had to swap the - from healthmod in akActor.ModAv("magicka", healthMod) for on and un equip to send the same amount it removed from health and put it into magicka and then remove it from magicka after unequipping.

Ah - UNDER dead... nice (:

Hehe

Also yours saves modded health values as well which is a real bonus. In my earlier testing I was at 164 buffed health and when I removed the item, I was down to 151 unbuffed health. Great way to unbuff yourself but not very practical.

Hey, there's no kill like overkill.
