Can I get the Base Id of a spell target with Papyrus?

[Pancakes22]

I'm trying to make a spell that adds a different item to your inventory depending on which NPC you use it on, say if you used it on Carlotta in Whiterun it would give you a differnt item than if you used it on Ysolda in Whiterun. Is this possible? If not, can I get the name of the actor? Eg using it on Carlotta would return a string with a value of "Carlotta Valentia"

Bump.

Apply a script to the magic effect of your spell. Use the event OnEffectStart, akTarget should provide the actor. You then compare akTarget to your pre-filled actor properties of whom you want to provide different items. But this requires you to list out all the NPCs you want to work with. Tedious work and not usable with mod added NPCs.

 

It's all I got. Brainstorming turned into a brain fart, sorry :P

To fill properties with mod-added NPC's use GetFormFromFile.

To get the name of the actor you will need SKSE, then use GetName().

Yes, this is the same FUGLY conclusion I've come to... and you're right, it is cumbersome, tendious, and limited to the extreme!

 

I'm still searching for a better solution or some kind of trickly work around, and I think there may be one in the usage of a Quest Script, and attached ReferenceAlias set to the ActorRef from akTarget, which is found in the Magic Effect Script, and set in a script which fires on the OnEffectStart event, as you've stated...

 

But I cannot find enough clear documentation / examples about how to use Quest ReferenceAlias mechanism to even begin the test coding of it?

 

There are lots of places where it is talked about, but no one provides a clear, step by step tutorial on how to implement it.

 

Here are a few related web pages:

https://github.com/xanderdunn/skaar/wiki/Understanding-Forms,-Object-References,-Reference-Aliases,-and-Persistence

 

Clearly, these people are all pursuing the same thing, but no one seems to have a clear idea how it is actually done!

 

I SEE it being done in some other complex mods, such as "Interesting NPCS", but those mods are far, far too large, and complex, to reverse engineer.

 

I (we) need a simple, clear cut, explained, tutorial example of how to use quests, ReferenceAlias to MagicEffect akTarget values, to pass an actor reference from one script to another.

 

In essence, we need a way to pass an instance (not base) actor ID from one script to another, through what amounts to a Global Variable, like we might pass an Integer of how many materials of a particular type a room or container holds.

Maybe next script samples are helpful to understamd something better. What can you do to transfer script data from one script to another.

Why not just put together a form list of the actor bases that you want to use and a matching formlist of the items. Then it is simple as

 

Int n = actorlist.find(AkTarget.GetActorBase())

AkCaster.AddItem(itemlist.getat(n))
