Back door spell scripting

Heya folks,
Looking for one of two things (or both if they’re available). Let us assume for a moment that I cannot install CPP (but am glad to plagiarize their scripts, as I have).

I want to get weapon buff spells to work on missile weapons (bows, xbows, slings, etc). I’ve gotten flame weapon (and family) to buff a stack of directly targeted arrows (using the same method Bless Weapon uses), but none of the other spells are working. I would think that the functions could be called, but I don’t know what I’m doing wrong mechanically.

My “2 things”, would be to help me make these function, or explain to me why they won’t.

I think you need to apply the effect to every item in the stack of missiles separately. So once you have determined the target in your inventory slot, you need to get the first item in the stack, apply the effect, then get the next item in the stack - applying the effect to that one. And so on until you get no more items in that inventory slot.

I already told him this is not a scripting issue but 2da issue and that he would need changes to itempropdef.2da and itemprops.2da merged into his haks. But it seems what you tell him one day, next day he has no memory of.

Also, the only reason why you cannot install CPP is thatt you don’t want to use it. There is no other content ever created that can be installed seamlessly into any module without problems*.
