Image Search not returning error...

4 posts in this topic

Hey guys, so I'm pretty new to this, but I think I have the basic concepts down. I'm trying to use Image Search and it works perfectly, and finds the image and sets the mouse cursor there. However, whenever it cannot find the  the image, I does not return a value, but instead I get this error:

"C:\Program Files (x86)\AutoIt3\Include\ImageSearchUpdate.au3" (58) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
$x=Int(Number($array[2]))
$x=Int(Number(^ ERROR

It has something to do with the include file, so I dont know how to fix it... Here is the include file that I am using

#include-once

Is there anyway for Imagesearch to return a value if it cannot find the picture?
Thanks!

ImageSearch should return 0 when the image is not found; did you edit the imagesearch.au3 yourself?
