Help with exists() function & logic

Hi all,

I do have a function which returns true/false if image is found. Similarly to exists(), but it tries up to 3 times in a row to make sure nothing is found given the environment is dynamic.

I have been using the first one below for weeks and it works fine, until I found a case in which I started suspecting a flaw in the logic. I then made the 2nd one which was even worse.

I am out of clues about what is wrong and would appreciate a 3rd party advice.


function isImageInRegion1(img, reg)
   local waitCounter = 0

   while not reg:exists(Pattern(img):similar(accuracy)) do
       toast("cant find "..img)

       waitCounter = waitCounter + 1
       if waitCounter > 3 then
           toast("cant find "..img.." - Limit reached - Abort!")
           return false
       end
   end

   return true
end



function isImageInRegion2(img, reg)

   for i = 1,3,1 do
       if reg:exists(Pattern(img):similar(accuracy)) then
           return true

       else
           toast("cant find "..img)

           if i == 3 then
               toast("cant find "..img.." - Limit reached - Abort!")
               return false
           end
       end
   end
end
Cordially,
Enissay
