Re: Setting the mouse location

See Omni's information on relative mouse coordinates:
http://www.omnigroup.com/developer/gamedevelopment/gdc2001/
That is the way to go!

There is a way to move the mouse with Carbon CoreGraphics (through the
remote operation API)
See CGRemoteOperation.h
Look at the OS X VNC server at <http://www.osxvnc.com/>.

CGPoint newCursorPosition;
CGEventErr err;
newCursorPosition.x = 0;
newCursorPosition.y = 0;

err = CGWarpMouseCursorPosition(newCursorPosition);

I found all of this information in about 1 minute searching at
http://cocoa.mamasam.com/index.php
