Not Getting Joystick buttons

Recommended Posts

I'm having trouble reading my joystick button press'. I can get the 6-axis and POV but the buttons are always returning 0 for me...

#cs
vi:ts=4 sw=4:
typedef struct joyinfoex_tag { 
    DWORD dwSize; 
    DWORD dwFlags; 
    DWORD dwXpos; 
    DWORD dwYpos; 
    DWORD dwZpos; 
    DWORD dwRpos; 
    DWORD dwUpos; 
    DWORD dwVpos; 
    DWORD dwButtons; 
    DWORD dwButtonNumber; 
    DWORD dwPOV; 
    DWORD dwReserved1; 
    DWORD dwReserved2; 
} JOYINFOEX; 
#ce
Opt("MustDeclareVars",1)
#include <DllMem.au3>
#include <GUIConstants.au3>

Local $JOYINFOEX_struct = "dword(13)"
Local $joy,$coor,$h,$s,$msg

$joy    = _JoyInit()

GUICreate("Joystick Test",300,300)
$h= GuiCtrlCreatelabel("",10,10,290,290)
GUISetState()

while 1
    $msg    = GUIGetMSG()
    $coor   = _GetJoy($joy,0)
    $s      = "Joystick(0):" & @CRLF & _
                "X: " & $coor[0] & @CRLF & _
                "Y: " & $coor[1] & @CRLF & _

                "POV: " & $coor[6] & @CRLF & _
                "Buttons: " & $coor[7]
    GUICtrlSetData($h,$s,1)
    sleep(10)

Figured it out, I needed to set the flags to tell it to report button press.
