Hello!  I'm REALLY new to Processing (first week or so) and myself and a few other people (who happen to be amazing at this language) are building a GUI for controlling a robot in Eclipse (that's not the problem).  What we want to do is use the mouse much in the same way as it would be used for a first-person-shooter.  Our problem is getting the mouse to maintain it's position in the centre of the screen while still acquiring information such as the "speed" and direction (which should be two values from -1 to +1; x and y axis).  I know there's a way to display in "presentation mode" which takes up the full screen, but I don't know if we can still acquire "speed" and directional data if the mouse is essentially trapped against the screen boarder. Is there a way to move the mouse itself and/or acquire data from the entire screen, not just the window?  Like I said, I have no idea what I'm doing.  Thanks!
