How to PixelSearch() faster? - autoit

Question

Using PixelSearch() and relative mouse movement I made this script lock the mouse cursor onto a color :
While 1
$pos = MouseGetPos()
$coord = PixelSearch($pos[0]+80, $pos[1]+80, $pos[0]-80, $pos[1]-80, $color, 10,5)
If IsArray($coord) = 1 Then
Local $iX = $pos[0], $iY = $pos[1]
If ($iX < $coord[0]) Then _MouseMoveRelative(1, 0);$iStepSize
If ($iX > $coord[0]) Then _MouseMoveRelative(-1, 0);$iStepSize
If ($iY < $coord[1]) Then _MouseMoveRelative(0, 1);$iStepSize
If ($iY > $coord[1]) Then _MouseMoveRelatsdive(0, -1);$iStepSize
GUISetState()
EndIf
WEnd
If I increase the steps it's faster, but it moves off target. If I decrease, it's slower but more accurate. How to make this as fast as possible?

Answer 1

This would be the fastest way because the mouse will move instantly
While 1
$pos = MouseGetPos()
$coord = PixelSearch( $pos[0]-40, $pos[1]+40, $pos[0]+40, $pos[1]-40, $color, 10,5 )
If IsArray($coord) = 1 Then
Local $iX = $pos[0], $iY = $pos[1]
If ($iX <> $coord[0]) Then _MouseMoveRelative($coord[0] - $iX,0)
If ($iY <> $coord[1]) Then _MouseMoveRelative(0,$coord[1] - $iY)
; GUISetState() This shouldn't be inside of a loop.
EndIf

If you still want to have a $iStepSize, do it like this:
While 1
$pos = MouseGetPos()
$coord = PixelSearch( $pos[0]-40, $pos[1]+40, $pos[0]+40, $pos[1]-40, $color, 10,5 )
If IsArray($coord) = 1 Then
Local $iX = $pos[0], $iY = $pos[1]
Local $iXOffset = $coord[0] - $iX, $iYOffset = $coord[1] - $iY
ToolTip( $coord[0] & " : " & $iX & #CRLF & $coord[1] & " : " & $iY, $iX, $iY)
If $iXOffset Then
If Abs($iXOffset) < $iStepSize Then
$iMoving = $iXOffset
Else
$iMoving = $iStepSize
If ($iXOffset) < 0 Then $iMoving *= -1
EndIf
_MouseMoveRelative($iMoving, 0)
EndIf
If $iYOffset Then
If Abs($iYOffset) < $iStepSize Then
$iMoving = $iYOffset
Else
$iMoving = $iStepSize
If ($iYOffset) < 0 Then $iMoving *= -1
EndIf
_MouseMoveRelative(0, $iMoving)
EndIf
EndIf
