ShadowStep Help!

[tc2r]

I would like to ask you for advice and tips and help on some code I've been trying to script.

 

It was taken from a mod that a guy gave up on and I think it could work... if I can figure out the right changes.

 

See in his mod, the user gets an spell which when cast at a actor, quickly moves the user towards that actor ultimately ending with the PC behind the actor... a "shadowstep".

 

I would like to change the code so that when NPCs use the spell on each other/the player, it will work for them too.

 

I think it should be as simple as changing the script so whever it says "player" I replace it with "the onewho cast this spell" but I can't figure out how to make that a reference ID.

 

Someone told me to use

"

long index

ref NPC

 

set index to GetScriptActiveEffectIndex

set NPC to GetNthActiveEffectCaster

"

But unless i'm using it wrong, this doesn't return the refid of the one who cast the spell. I've tried the following code and replaced every instance of "player" with "npc" and it didn't work.

 

technically speaking when this script is finished it should work for all actors, not just npcs or player. Could you look at it and see if you can figure out what i'm doing wrong please?

 

btw I have aim, yahooIM, and xfire, do you use an instant messaging sytem?

The issue is that the reference of the caster cannot be obtained unless the spell is either cast on self or obrained through GetNthActiveEffectCaster. However since GetNthActiveEffectCaster is a OBSE function, and doesn't have clear usage documentaton, you may need to do quite a bit of work trying to figure out how to make it return the ID of the caster.

 

As for the scripting, that's a bit too much math for something that you want to run quickly. Regardless, it seems you have some inconsistancies between what you're trying to do with references. Unless I'm reading it wrong, you want to be moving self, not player. If you reverse those two within the updte block, where appropiate, then attach this script to a self cast spell, it should function. You could even replace instances of "player" with a reference gained from "getcombattarget" to make the NPC appear behind whoever they're fighting.
