I just meant play as normal with the bounding box, but then at the push of, lets say the C button, the Screen would lock to the cursor and they would move as one allowing me to move the camera quickly in any direction as long as I hold the camera lock button. When I let go of the lock button "C" then the camera would stay where I left it until I moved out of the bounding box to move it again.
This would have no effect on character movement whatsoever as that would still be controlled independently by the analog stick.
Ok, so you're saying once you press C, the bounding box "disappears" and any deviation your Wii Remote makes from the IR "origin" creates immediate turning?
I hope "lock-on" doesn't imply locking the cursor to the center of the screen. That basically recreates classic "analog stick" control (aiming/looking via camera drag), creating a scenario where you use the advantage of the Remote (free-floating snap-aiming inside the bounding box, camera drag outside the box) then suddenly take it away (100% camera drag).
So far, no Wii FPS offers that sort of switcheroo. So please try out my scheme first, since we're spending all this time on make-believe.
