I've no longer got any RPG Maker installed on my comp. for some reason, so this may be wrong. If you are, say, wanting the camera to pan across the screen to look at something (say you enter a big hall, and the camera pans up the hall to your enemy standing waiting at the other end) then I seem to remember it moving by squares...

Don't take my word for it though...haven't done this for I don't know how long so...
