How does pixelsearch work?

@careca there are times you have to understand to stay out...  this is one of them.

Added the thing @careca told me too but it still won't find the right pixel, guess i have to find a better pixel.

[Jos]

Ok... BACK to the helpfile:

which part of this extensive part of the helpfile code did you NOT implement?

; Find a pure red pixel in the range 0,0-20,300
Local $aCoord = PixelSearch(0, 0, 20, 300, 0xFF0000)
If Not @error Then
    MsgBox($MB_SYSTEMMODAL, "", "X and Y are: " & $aCoord[0] & "," & $aCoord[1])
EndIf

... and WHY is that so damn important?

Why this is so damn important?
When i am learning something i want to know everything, explore the language and create as many possibilities as possible for me to use the language that i am learning. Pixelsearch have for a long time been a huge problem for me.

Because it is the answer to your question and to be as blunt as you: What about you kick you brains into gear and start thinking for a bit in stead of constantly asking for cookies ?

So what is it going to be? Answer my last question or being defensive because I am hurting your feeling?
(Which I am not, just trying to sort it issues out yourself in stead of  actually giving those cookies   )

I rewrote the code to get in to my own words of code

Global $left,$top,$right,$bottom,$color
$left = 2384
$top = 613
$right = 2453
$bottom = 700
$color = 0xEDBF27

Global $pix = PixelSearch($left, $top, $right, $bottom, $color, 10)

MouseMove($pix[0], $pix[1])

I have also tested the example code but with no luck.
Getting the same error as before.

 

; Find a pure red pixel in the range 0,0-20,300
Local $aCoord = PixelSearch(2379, 610, 2458, 697, 0xE1B118)
If Not @error Then
    MsgBox($MB_SYSTEMMODAL, "", "X and Y are: " & $aCoord[0] & "," & $aCoord[1])
EndIf

I am getting no erros from the ex code 
">Exit code: 0    Time: 0.4913"
But i am not getting an msgbox so it must be some sort of error

I almost drowned on my bottle of water.

[Bamse]

Is my mistake obvious?

Found it, i need to include this>
 

#include <MsgBoxConstants.au3>

if you don't include that au3 you wont get message box

#include <MsgBoxConstants.au3>

; Find a pure red pixel in the range 0,0-20,300
Local $aCoord = PixelSearch(0, 0, 20, 300, 0xFF0000)
If Not @error Then
    MsgBox($MB_SYSTEMMODAL, "", "X and Y are: " & $aCoord[0] & "," & $aCoord[1])
EndIf

Nice, but did you understand it? Do you understand the need for the error checking? Do you understand why it was giving an error?

Great and all of that without the @error checking ...    wish you all the luck you can get and hope that pixel is found each time or you will be  screwed.
I was fun to deal with you and rest assured I will not bother you any further and leave you the code slaves that are willing to help people that fail to think for themselves.

Well, the text in the msgbox of the screenshot he posted is in accordance with the example that has error checking,

so im not sure he didn't use it, im just unsure he understands it.

It's nice to see people helping other out like you guys are doing. Why are you calling them slaves?

Funny to see you even interpret that statement as if it is about the others and not about you asking for cookies like a child. 

Over and out.

The error happen because it couldn't find the right color. I needed to use shades.
Error checking is used because we know where the error came from.

That wasn't quite the answer i was looking for, something more in the lines of:

The error checking prevents a "critical" error if a pixel is not found, because without it, it's gonna crash trying to read a non existing variable.

But i think you got that.
