I'm teaching myself the ways of modding (seeing as how i skipped out on doing so on Oblivion & Morrowind), and I'm starting out by making a very simple spell that shoots, say, glass arrows as a projectile. I've worked out everything just fine so far, but when it comes time to run the thing I can indeed shoot arrows out of thin air, but if I go to pick them up i get a crash to the desktop. Any ideas as to why/how I can fix this? Or should I just move on to something else? Thanks.

I have a question, how did you have it shoot arrows, I'm trying to figure this out. Would you post your script?

Are you using a vanilla projectile? It needs to have the 'can be picked up' check box marked.
What command are you using to shoot the projectile?

I kinda want to do the opposite... I have a post about having a m16a2 not fire like a bow... one of the ways i thought of was a spell attached to it, but have it not run on charges but only if i had ammo still.... like the silver weapons, their enchant is always on, so this would like always be on but only shoot the projectile if i have the m16a2 ammo. But I have no idea how to do that.
