[LE] Help with debug.MessageBox() on a spell hit

[Cristobot]

Newbie here!

I want a spell to show some information about any NPC that it hits.

1) I've created a Magic Effect that is Fire and Forget

2) I've created a spell with that Magic Effect

3) When I fire the spell, I see that it hits the NPC due to the hit effect art

Where I NEED HELP:

For the Magic Effect, I've tried scripting an onHIt() Event to show a MessageBox("Hello World") when the spell hits something...

but nothing ever happens! (My script compiles, btw)

Here is my simple script:

Scriptname crbtGetNPCData extends ObjectReference

Event OnHit(ObjectReference akAggressor, Form akSource, Projectile akProjectile, bool abPowerAttack, bool abSneakAttack, bool abBashAttack, bool abHitBlocked)

debug.messagebox("Hello World")

EndEvent

Unfortunately, OnHit has to run on the object being hit and not the object causing the hit. Unsure of the best approach to what you want to achieve. Perhaps apply a magic effect to the target which contains a script that shows your information in the OnEffectStart event.

[maxarturo]

The "OnHit()" event fires when the object gets hit and not for the object that hits it, as you have it now.

If you want the message to appear ONLY when the spell hits something, then you need to go a little further.

1) Create a unique 'Explosion' that your spell will use.

2) Create an "Enchantment", it can be an 'Empty' magic effect > archetype Script.

3) In your Enchantment's Magic Effect add a script:

Event OnEffectStart(Actor akTarget, Actor akCaster)

MyMSG.Show()

EndEvent

* I use 'Message' instead of a 'Notification' because is easier to translate your mod later on.

4) Add your Enchantment to your 'Unique Explosion'.

5) Add the explosion to your Scripted Magic Effect.

6) Add the Scripted Magic Effect to your spell.

You are done !...

Have a happy modding.

EDIT: I didn't intend to post the same info as IsharaMeradin did, but she posted it while i was writing. She was faster....

You can use OnEffectStart. Fire and forget spells with a projectile only take effect when they hit an actor. I do something similar in my mod Mark and Summon NPC Friends: https://www.nexusmods.com/skyrim/mods/96380

dylbill suggestion is more suitable for this occasion.

I got carried away cause i was trying to fix an issue with one of my assets that use the technic i posted, when i posted it...

* Not that this won't work.

Thanks so much to everyone for the feedback! I will give it a try!

 

I'm a veteran programmer but totally new to the Creation Kit and Papyrus, which is both cool and confusing.

 

I eventually want to show some information about the NPC that was hit by the spell, and starting with a debug.MessageBox() seemed like the way to begin. Eventually I'll have to show some other kind of information box?

[IsharaMeradin]

You can still use a message box to show information. You can do things like:

 

Debug.MessageBox("Target: "+akTarget.GetName()+"; Health: "+akTarget.GetActorValue("Health"))

 

akTarget is just a placeholder for whatever variable you might be using to reference the target actor

FYI - GetName requires SKSE

[Cristobot]

Thanks!

I was able to use:

Debug.MessageBox("Health: "+ akTarget.GetActorValue("Health"))
Debug.MessageBox("Magicka: "+ akTarget.GetActorValue("Magicka"))
Debug.MessageBox("Stamina: " + akTarget.GetActorValue("Stamina"))

How can I get NPC values like their skills?

Ultimately, I want to list an NPC's Perks, if they have any.

 

Is there some comprehensive reference for Papyrus? I seem to be searching all over the place for simple answers, although you guys have been the most help so far! :smile:

Skills are also actor values. You can find a list here: https://www.creationkit.com/index.php?title=Actor_Values

 

Instead of using 3 message boxes, you can use a single message box with \n to denote new lines. You can also use \ to continue your papyrus line on the next line so it's easy to see. Example:

Debug.MessageBox("Health: " + akTarget.GetActorValue("Health") + \
"\n Magicka: " + akTarget.GetActorValue("Magicka") + \
"\n Stamina: " + akTarget.GetActorValue("Stamina") + \
"\n One Handed:" + akTarget.GetActorValue("OneHanded"))

I do not know how to use it. But SKSE has a GetPerks function on the ActorValueInfo script.
