Projectile Hit Detection for NWN

Projectile Hit Detection adds collision detection into Neverwinter Nights for the purposes of spells, abilities, and other projectiles as you ordain.  The demo module contains an assortment of items with the scripts enabled on them, and a nifty firing range for you to experiment on.  What you'll see is that each item has a unique ability, some of familiar spells, and some new, all of which launch a projectile which will process hit detection in real time.  For instance, if you target the Fireball wand past an object or creature, the Fireball will hit the object or creature instead of the spot you aimed at.  If an object or creature moves in the way after you cast, it will be hit too, just like it should.

All of this has been created with an API in mind to make it easy for anyone to use and create new abilities or spells using the technology with a fairly minimalist configuration script defining what the spell/ability should do and how it will behave, meaning you don't need to know about how the physics engine works.

This is a demo of the technology, intended to showcase its many possibilities.  Once it matures a little, my intent is to put together a full game mod which changes all appropriate spells and abilities to use hit detection, maybe even with a few new spells/abilities.  Ultimately, the intent is for this to add new gameplay to Neverwinter Nights.

Screenshots make it a little hard to tell the full story, so here's a narrative demonstration video to show you what it's all about:
