Problem with projectiles from FPS tutorial:

I've been using the instructions detailed in the FPS tutorial to implement some basic projectiles, and they aren't behaving at all like they're supposed to. They don't explode when they hit a wall or object, and sometimes fire vertically instead of where the camera is looking.

I've triple-checked all of the Javascript and it's all as outlined in the tutorial. My suspicion is that it may have something to do with the controls in the inspector window (checkboxes, variables etc) but since the tutorial gives no indication of what the proper settings are I have no clue what's going wrong.

Sounds like the projectiles are going according to the world, and not the local xyz.
