Basic idea for a Automatic Casting Perk : V

» Thu Jun 21, 2012 4:51 am

Hey guys,

Before I go on with scripting I would like to know your opinion if this idea is basically working as shown in the concepts. If you have better ideas, please tell me.
I am a total greenhorn in scripting, especially in terms of terminology and syntax, so please be lenient with me.

My perk idea:
If you have a One-Handed Weapon equipped in either hands and a spell in the other. After hitting an opponent with your One-Handed Weapon, if hostile the spell should be cast automatically at the same target. If not hostile, it should be cast at yourself (e.g. restoration spells).

Concept:
The basic idea is to distribute a script (ActivatorScript) containing an On-Hit activator to the Target, which then returns the targets' ID and change a variable "stating" the target got hit. The changed variable then can be used as an activator for another script (FireSpellScript) that fires the equipped spell at the target with the corresponding ID. It should be possible to define changes inside the FireSpellScript.

Momentary route:
1) I use the example of RandomNoob on the ck-wiki "Dynamically Attaching Scripts" - basically distributing a spell containing the ActivatorScript by using a Cloak which is placed on the player.
I just replaced the wiki-examples MonitorEffect-script with the ActivatorScript shown below. Additonally i am creating the FireSpellScript which will be put on the player and use the targets ID as well as the activator variable.

Another idea:
2) Using an ability with delivery type "OnContact" to directly deliver the ActivatorScript and then go on as above.

I have no idea if 2) will work at all and if yes, does it have big advantages over 1)? Maybe some modders can give me some feedback on these 2 ways to distribute the ActivatorScript or present me alternatives of how to accomplish this perk.

Regarding 1) I did some scripting. I dont have an idea what makes an object unique (or actor? - the NPC which is affected by the script). Therefore i just read out the FormID but I might be wrong totally.
Additionally i am not sure how to deliver the variables to another script. Afaik one can do this via properties.
(At the moment i learn by Trail and Error as well as reading up and down the wiki).

Working ActivatorScript

Frame of FireSpellScript (maybe it helps to understand my intention)

Ps.: Can anyone insert the URL to RandomNoobs Wiki entry? I will be allowed to link in 4 days.

I think you're making this much more complicated that it has to be.

Your perk can just use the perk entry point "Apply Combat Hit Spell" to apply a spell to the NPC you hit. Just give it the conditions that the player has to be equipped with a one handed sword and a spell (http://www.creationkit.com/GetEquippedItemType).

If you use the "Apply Combat Hit Spell" perk entry point, you can choose the spell to be a scripted spell. The script can force the caster (ie the player) to cast whatever spell is in his/her left hand.

There's no need to go through all the trouble of dynamically attaching scripts to actors.

Ok, did it. And its working. Not everything tested but working with destructive spells so far. need to tweak it and more advanced testing.

Dispel()EndEventt

Does the actor who casts the spell use perks or do i have to add conditional checks and effects seperatly to cover the perks' effects which affect the spell?
I figured out that that "cast" doent deplete magicka. It seems I have to use UseMagic - AI-Packages....
