so today I was working on a sword script for battlezone and something interesting happened.
basically I was working inside a child prim for hold all of the scripts and animations. The sword of course on my right hand. that child prim was rotated so some particles would be 'pretty'.
turns out that having that rotated child prim made me swing to my left side(fire sensor to left side), IE draw a line straight out of my arm and on each side of that was 45 degrees(total 90) of what I would hit.
just some very interesting behavior I never saw before. also when I put everything in the parent prim it fired its sensor forward.
