PixelChecksum using MouseGetPos coords

7 posts in this topic

Hello AutoIters, I am trying to write a short script that will grab the mouse position, grab a pixel checksum around it, and monitor it for changes.

Here is what I have so far

Opt("MouseCoordMode", 0)
Opt("MustDeclareVars", 0)

Global $mousepos = MouseGetPos()
Global $pixelpos[1][2][3][4]

;~ $pixelpos[1] = $mousepos[0] - 5 ;left
;~ $pixelpos[2] = $mousepos[1] + 5 ;top
;~ $pixelpos[3] = $mousepos[0] + 5 ;right
;~ $pixelpos[4] = $mousepos[1] - 5 ;bottom
;~ $pixelcheck = PixelChecksum($mousepos[0] - 5, $mousepos[1] + 5, $mousepos[0] + 5, $mousepos[1] - 5)
MsgBox(0, "Pixel Checksum range", "Pixel Checksum range is" & $pixelpos)

And I keep getting errors such as "array variable has incorrect number of subscripts or subscript dimension range exceeded.:"

Any clues on how to fix this?

You need to look again at how arrays are declared and used. A four element one-dimensional array is declared this way:

Global $pixelpos[4]
And the index is zero-based, so the elements are $pixelpos[0] thru $pixelpos[3].

:(

Edit: Oops, forgot Global keyword.

blckpythn,

Welcome to the AutoIt forum. :(

This will seem a lot of comment - do not get discouraged! :D

1. If you change the MouseCoordMode, you also need to change the PixelCoordMode or the 2 will not match and you will not be looking at the pixels you think you are. :)

2. The default value for the MustDeclareVars mode is 0, so there is no need to declare it.

3. You need to read the array tutorial in the Wiki here. B) You have declared $pixelpos as a 4D array - so you would need to have 4 indices each time you use it - no wonder youwere getting errors. What you need is a 4-element 1D array - which has elements 0-3, not 1-4 by the way. ;)

4. You were trying to display the $pixelpos array in the MsgBox, not the $pixelcheck checksum - so nothing would ever show.

Take a look at this:

Opt("MouseCoordMode", 0)
Opt("PixelCoordMode", 0)
;Opt("MustDeclareVars", 0)

Global $mousepos = MouseGetPos()
Global $pixelpos[4]

$pixelpos[0] = $mousepos[0] - 5 ;left
$pixelpos[1] = $mousepos[1] + 5 ;top
$pixelpos[2] = $mousepos[0] + 5 ;right
$pixelpos[3] = $mousepos[1] - 5 ;bottom

$pixelcheck = PixelChecksum($pixelpos[0], $pixelpos[1], $pixelpos[2], $pixelpos[3])

MsgBox(0, "Pixel Checksum range", "Pixel Checksum range is" & $pixelcheck)

Please ask if anything is unclear. :)

Wow, very informative. I realize now what I did wrong, and thank you for the code Melba23.

One more question.

Occasionaly when I type in Scite it will overlap on text there instead of inserting it between the characters that my cursor is in.

blckpythn,

Nothing to do with SciTE. :) You have probably pressed your Insert key inadvertantly. If I am in Insert mode SciTE gives me an underscore ( _ ) as a cursor rather than the usual vertical bar ( | ) - try it yourself and see if it does the same for you. :(
