Moving mouse relative to center

Recommended Posts

I'm trying to work out a "relative" version of the Smoother mouse move.

This code demonstrates a relative mouse move, from the screen center context, as in a 3D game, where instead of the pointer moving, your whole view moves. When a game traps your mouse, this is the context.

Func _MouseMoveRelative ($iX, $iY)
    Local Const $MOUSEEVENTF_MOVE = 0x01
    DllCall ("user32.dll", "int", "mouse_event", _
                                "int", $MOUSEEVENTF_MOVE, _
                                "int", $iX, _
                                "int", $iY, _
                                "int", 0, _
                                "int", 0)
EndFunc

This is the "Smoother Mouse Move" script by DtTvB, which creates a 2 point spline path and moves the mouse point along it. I want to use this in a relative fashion, for smooth camera transitions w/ au3irrlicht.

CODE
; Smoother Mouse Move

; by the DtTvB

; Ease in function

func __calci1($i, $sm)

return $i ^ $sm;

endFunc

; Ease out function

func __calci2($i, $sm)

return 1 - ((1 - $i) ^ $sm);

endFunc

; Ease in out function

func __calci($i, $sm)

if ($i < 0.5) then

return __calci1($i * 2, $sm) / 2;

else

return (__calci2(($i - 0.5) * 2, $sm) / 2) + 0.5;

endIf

endFunc

; Ease backward function

func __calof($i, $sm)

if ($i < 0.5) then

return __calci($i * 2, $sm);

else

return __calci((1 - $i) * 2, $sm);

endIf

endfunc

; MAIN FUNCTION

func mouseMove2($x2, $y2, $m)

$x1 = mouseGetPos(0);

$y1 = mouseGetPos(1);

$xv = random(-100, 100);

$yv = random(-100, 100);

$sm = random(1.5, 2);

for $i = 0 to $m

$ci = __calci($i / $m, $sm);

$co = __calof($i / $m, $sm);

$cx = $x1 + (($x2 - $x1) * $ci) + ($xv * $co);

$cy = $y1 + (($y2 - $y1) * $ci) + ($yv * $co);

mouseMove ($cx, $cy, 0);

next

endFunc

fixed some copy/paste issues :)

Anyone got an idea? I've tried replacing mousemove in the script with the mousemove2 function, and it doesn't work. It ends up pointing the camera straight up.
