I'm using the script above to search for images on the screen, however, I'm getting this error information on the console:

>"C:\Program Files (x86)\AutoIt3\SciTE\..\autoit3.exe" /ErrorStdOut "C:\Users\andre\Desktop\autoIT\ImageSearchDLL\teste-imgsearch.au3"    
"C:\Users\andre\Desktop\autoIT\ImageSearchDLL\ImageSearch.au3" (52) : ==> Subscript used on non-accessible variable.:
if $result[0]="0" then return 0
if $result^ ERROR
>Exit code: 1    Time: 2.212


My code bellow:

#include <ImageSearch.au3>

HotKeySet("p", "checkForImage")

global $y = 0, $x = 0

Func checkForImage()
local $search = _ImageSearchArea('img2.png', 1, 0, 0, 1155, 621, $x, $y, 0)
If $search[0] = 1 Then
MouseMove($x, $y, 10)
EndIf
EndFunc

while 1
sleep(200)
WEnd


The line (52) of the script is this line: 
   

if $result[0]="0" then return 0


Is my ImageSearch.au3 script out of date?


Thanks all for the help!

AndreRox,

No, we have moved the thread to the correct section. So now you just need to be patient.
