My apologize if i fill the forum with question but i am working on a mod that is surely ambitious, and i need your help! Do you know how to create toggleable power?

Easy easy easy.

Spell Property toggleAbility  Auto  Event OnEffectStart(Actor akTarget, Actor akCaster)     If akTarget.HasSpell(toggleAbility)          akTarget.RemoveSpell(toggleAbility)     Else          akTarget.AddSpell(toggleAbility, false)     EndIfEndEvent

Set up a script effect magic effect with that script attached, fill the property with the constant-effect ability you're wanting to toggle, and then make a spell with the script magic effect to act as the actual toggle.

Hey my thanks! i am a newcomer in modding another thing, do you know if is it possible associate a power to a perk, so when you take the perk you unlock the power?

There's a "quest" section of the perk entry point menu, and it may be possible to use a quest stage to add the power to the player? However, I have not explored this "quest" part of the perk system at all, so I'm just speculating. I have no idea how it works
