If this is on Windows then I think the only good way is to grab the mouse directly using DirectInput. This is what we've done to do Quake-style controls.
I can probably include some cut-pasted examples of how we've done it if you like. As I recall, we just query how far the mouse has been rolled every frame... and screen boundary doesn't stop the rolling. -Paul maruti borker wrote: > When should i actually use requestWarpPointer ?? at every frame ? > > On Dec 11, 2007 2:27 AM, maruti borker <[EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]>> wrote: > > > Ok , suppose i am calculating the amount of steering from the center > of the screen ... even then when the mouse reaches one corner of a > window it wont be able to move any further , thus from that point > the diffrence will always be zero wont it be ? > > > On Dec 10, 2007 2:54 PM, Robert Osfield <[EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]>> wrote: > > HI Maruti, > > When I've used mouse for steering I've always implemented a scheme > where the delta of the mouse form the center of the screen sets the > speed of rotation, for an example of this see the DriveManipulator. > This way you never get limited by mouse movement beyond limiting the > maximum speed of rotation. > > Robert. > > On Dec 9, 2007 7:46 PM, maruti borker < > [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>> wrote: > > > > I am trying to develop a normal walkthrough program in OSG . > I am trying use > > wasd for movement and mouse for rotation . > > > > W-front A-left D-right S-back . > > > > The wads part is done , but when it comes to mouse movement i > am facing a > > small problem . > > > > What i am trying to do is , i am calculating the change in x > co-ordinate and > > y co-ordinate of the mouse while it is moving .
