How recover the $x and $y values of $xy to get coordinates

Recommended Posts

Posted (edited)

Hello,
I’m looking to recover the $x and $y values of $xy to get coordinates. I’ve tried everything a bit but it doesn’t give me anything. Can you help me, please?

Here is an example with StringSplit:

Func FromNostoScreenCoords($_x, $_y)


    $aCurrentLoc = 37.25;GetCurrentPosMem($x, $y)    ; $aCurrentLoc = 37.25
    $CurrentLoc = StringSplit($aCurrentLoc, ".")

MsgBox($MB_SYSTEMMODAL, "CurrentLoc", $CurrentLoc)  ;; //  = nothing    Why ?

    $xd = $_x - $CurrentLoc[1]
    $yd = $_y - $CurrentLoc[2]

    $w = -0.515 * $xd + -0.514 * $yd + -0.686
    $x = (-1.682 * $xd + 1.683 * $yd + 0) / $w
    $y = (-1.54 * $xd + -1.539 * $yd + 2.307) / $w
    $Z = (-0.515 * $xd + -0.514 * $yd + -0.686) / $w
    $x = ($x + 1) / 2 * 800
    $y = (1 - $y) / 2 * 600

    ;; Handle out of screen scenarios
    While $x >= 800 Or $y >= 600 Or $x <= 0 Or $y <= 0
        $xd = $xd / 2
        $yd = $yd / 2
        $w = -0.515 * $xd + -0.514 * $yd + -0.686
        $x = (-1.682 * $xd + 1.683 * $yd + 0) / $w
        $y = (-1.54 * $xd + -1.539 * $yd + 2.307) / $w
        $Z = (-0.515 * $xd + -0.514 * $yd + -0.686) / $w
        $x = ($x + 1) / 2 * 800
        $y = (1 - $y) / 2 * 600
    WEnd

    Dim $return[2]
    $return[0] = $x
    $return[1] = $y
    Return $return
    MsgBox($MB_SYSTEMMODAL, "FromNostoScreenCoords", $return)  ; ; //  = nothing    Why ?

EndFunc   ;==>FromNostoScreenCoords

Bibopp,

Your MsgBoxes show nothing because you are attempting to show an array - which is what is returned by StringSplit in $CurrentLoc and explicitly defined by you when declaring $return.

If you want to display an array then you need to uses, unsurprisingly, _ArrayDisplay.

Bibopp,

When you reply in future, please use the "Reply to this topic" button at the top of the thread or the "Reply to this topic" editor at the bottom rather than the "Quote" button - I know what I wrote and it just pads the thread unnecessarily. Thanks in advance for your cooperation.

I get an ArrayDisplay dialog when I run your first posted script, but I never see the second as you never escape from your While loop - as this modified version shows:

#include <Array.au3>

FromNostoScreenCoords(1, 1)

Func FromNostoScreenCoords($_x, $_y)

    $aCurrentLoc = 37.25 ;GetCurrentPosMem($x, $y)    ; $aCurrentLoc = 37.25
    $CurrentLoc = StringSplit($aCurrentLoc, ".")

    ;MsgBox($MB_SYSTEMMODAL, "CurrentLoc", $CurrentLoc) ;; //  = nothing    Why ?

    _ArrayDisplay($CurrentLoc, "1", Default, 8)

    $xd = $_x - $CurrentLoc[1]
    $yd = $_y - $CurrentLoc[2]

    $w = -0.515 * $xd + -0.514 * $yd + -0.686
    $x = (-1.682 * $xd + 1.683 * $yd + 0) / $w
    $y = (-1.54 * $xd + -1.539 * $yd + 2.307) / $w
    $Z = (-0.515 * $xd + -0.514 * $yd + -0.686) / $w
    $x = ($x + 1) / 2 * 800
    $y = (1 - $y) / 2 * 600

    ConsoleWrite($x & " ~ " & $y & @CRLF)

    ;; Handle out of screen scenarios
    While $x >= 800 Or $y >= 600 Or $x <= 0 Or $y <= 0
        $xd = $xd / 2
        $yd = $yd / 2
        $w = -0.515 * $xd + -0.514 * $yd + -0.686
        $x = (-1.682 * $xd + 1.683 * $yd + 0) / $w
        $y = (-1.54 * $xd + -1.539 * $yd + 2.307) / $w
        $Z = (-0.515 * $xd + -0.514 * $yd + -0.686) / $w
        $x = ($x + 1) / 2 * 800
        $y = (1 - $y) / 2 * 600

        ConsoleWrite($x & " ~ " & $y & @CRLF) ; As you can see these values mean you will never escape the loop! <<<<<<<<<<<<<<<<

        Sleep(500)

    WEnd

    Dim $return[2]
    $return[0] = $x
    $return[1] = $y
    ;Return $return ; Move to after the next line or that line will never be executed <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    ;MsgBox($MB_SYSTEMMODAL, "FromNostoScreenCoords", $return)   ; ; //  = nothing    Why ?

    _ArrayDisplay($return, "2", Default, 8)

    Return $return

EndFunc   ;==>FromNostoScreenCoords

You need to look at the "out of screen" calculations as they are obviously not working as you intend.
