Hi there,

I have a function that returns multiple coordinates with a 2 dimensional array, eg.:

$array[0][0] = 123, 423

$array[1][1] = 1214, 12312

$array[2][2] = 2344, 1231

Just some random numbers.. I hope you understand what I mean (i'm not sure how 2 dimensional arrays work, and the help file didn't really help me).

So, now I want to know how I receive 12312.. should I do this like this?

$array[1][1] ?

Because I tried that but got an error..

Using it in this script but getting an error when the pixel that is being looked for is (temporarily) invisible.. also I noticed $i going higher then UBound($check), even though that should not be possible in my script?

#Include <Misc.au3>
#Include <Array.au3>

This is ugly code and it takes twice as long to fetch:

$minimapcoordleft_x = MouseGetPos(0)

$minimapcoordleft_y = MouseGetPos(1)

Do this instead:

$minimapcoordleft = MouseGetPos()

This way X is in element [0] and Y is in element [1]

Okay.. but what about my real problem? This does not solve it of course.

Ok, I made a log and apparently $i is becoming higher then the actual numbers of Ubound($check) when the PixelSearch function fails to find the pixel.

This is where it crashes.

Does anyone understand however why $i becomes higher then UBound($check) ? I made a check for this so it should not happen right?

[EDIT]

Oh, apparently it is not. UBound is getting higher when it crashed, see new log file where UBound is the second value (after -):

So how come it goes wrong here?

UBound returns the number of elements. If you have 10 elements then the elements are [0],[1],..[9]

SO you must not let $i go higher than Ubound - 1. I think you need to change this 

ElseIf $i < UBound($check, 1) Then
                $i += 1

to

ElseIf $i < UBound($check, 1) -1 Then
                $i += 1

Thanks for the reply, however it does not work. I still get this error:
