Does anybody know how I can read the RELATIVE Mouse movement without using Direct Input(there has to be a Win32 function that does that???) --Mancubus

Handle the WM_MOUSEMOVE ?

It returns only the ABSOLUTE coordinates, not the realitives.

The relatives are the mouse position change since the last read of its state. That''s what I need.

Q2 uses it(I''m sure that it uses it cause I haven''t DirectInput on my PC and it runs pretty good.), so there HAS to be a way....

Call

BOOL GetCursorPos(
LPPOINT lpPoint // address of structure for cursor position
);

And store the previous value to get the relative.

Thanx!!!

That works fine until the mouse cursor hits the edge of the screen.

At each tick, test where the mouse cursor is relative to the center of the screen, then restore the cursor to the center of the screen.

Yes that''s right. There has to be a function SetCursorPos. It''s easier to set the cursor position to 0,0 and then to read the pos. I''ll get directly the relative coordinates then...

No, being lazy here won''t work. If you put it at [0,0], you won''t get any movement if the user tries to move the cursor up or left. So, put it at center screen, and do the extra math...

junk = GetCursorPos(vPos)
OffSetX = vPos.X - (ScreenWidth/2)
OffSetY = vPos.Y - (ScreenHeight/2)
vPos.X = (ScreenWidth/2)
vPos.Y = (ScreenHeight/2)
junk = SetCursorPos(vPos)

That will work. (ScreenWidth/2) and (ScreenHeight/2) should be either constants, or pre-calculated.

Oh yeah.... you''re right. Thanx!!!

i''ve found SetCursorPos to be very slow... anybody know why? or anybody have any other ways around using it?...



Thank you for your bandwidth.
