I have used this script, above, for some time without any problems for cutting down trees. I thought I could use this script, amended, to register when an object is hit by a spell - in my case a movable static, a fire volume.
I changed the script, just the essentials for now to see if it worked, but it won't compile.
The amended script is the top one - for some reason this editor is messed up.
These are the errors...

psc(12,14): argument aisource is not specified and has no default value
psc(12,61): type mismatch on parameter 1 (did you forget a cast?)

Thanks for your time.

Specify what aiSource will be. Left Hand, right hand, etc.

But the script requiring the woodaxe (above) allows it to be equipped in either hand. How does it differ from a spell?

Anyway, I did as Wiki said and this is the script, it compiles but it doesn't do what it supposed to do i.e. fire and damage triggerbox do not disable.

Did you see your debug trace/notifications? Give some more detail to help us figure out where it might be going wrong

Also, why not just check whether (akSource == (yourSpell as Form))?

I'm not so good at scripting with forms, something I am unsure of but it would be good to have a form that includes all cold spells. I need help with that.
Effectively I have fires on top of a surface of water, see shot. Player has to travel through these but gets damaged if he/she enters a fire. I put a fire damage triggerbox in each fire fx as the fire itself does no damage. By casting a cold spell on these fires the player can extinguish them. The fire is a movable static, BFXFireVol01, and I run the script on it.

I've got it working. Seems the fire fx won't register hits, so had to use an activator. Could somebody help me script the event to use a form that includes all cold spells, ice spike, icy spear, etc? Would be appreciated.

Couldn't you use something like:

Event OnHit(ObjectReference akAggressor, Form akSource, Projectile akProjectile, Bool abPowerAttack, Bool abSneakAttack, Bool abBashAttack, Bool abHitBlocked)If((akSource.HasKeyword(MagicDamageFrost));do code stuff hereEndEvent

In the spells form there isn't an option to add keywords, nice idea though.

I just tested it and it worked fine, because the keyword is in the magic effect, which gets passed on automatically to the spell form.

Don't just copy-paste my code earlier though; there's an extra parenthesis typo and you ought to use a keyword property too.

Keyword SHOULD work if only everyone (modder and including Bethesda) had use the keyword system constantly in all the spells. But that is not the case.

I found that while making my mod to make shields block all elemental attacks that checking for the keywords will not always work. In fact there is even a special keyword condition check (EPMagic_SpellHasKeyword) used JUST FOR PERKS!

I finally came up with a long script that combined looking for keywords in 5 different ways, and that still worked inconstantly after testing on many different frost spells and shouts from both vanilla and mods.

In the end I had to check the NAME of the spell to look for the words frost or cold and such.
