If Statements

[Jmjl]

Ok, I know this sounds kind of n00bish but I can seem to figure something out invovling If statements. I've looked in the help and it didn't help . I understand the concept and I know how it works (I program in VB) only I can't seem to figure this out. What I want to do is constantly be checking the pixel colour in a specific pixel and if the pixel colour equals a certain hex value say red FF0000 then to click on that location only I can't figure it out. Thanks for the help!

Hi,

did you try it, already? Show your script, please.

So long,

Does it look something like this?

While 1 = 1
$pixel = PixelGetColor(10,100);or whereever your location is
If Hex($pixel) = FF0000 Then
;do stuff here if it is red
;Else
;could do an else, but its not required
EndIf
WEnd

If so, you're on the right track.

Yeah, that is pretty much exactly what my code is except I didn't have the

If Hex($pixel) = FF0000 Then

I didn't have the hex part. Does that really matter? Either way when I run your code I still get the error:

Any solutions?

Hi,

what about showing your try? Maybe this helps out 'FF0000'

So long,

Your use of the hex number is wrong. For hex you need 0x prefix. Try:

$Color = 0xFF0000 ; edit for color (RGB hex)
$x = 200 ; edit for x pos
$y = 200 ; edit for y pos
While 1
     If PixelGetColor($x,$y) = $Color Then
          ;do stuff here if it is red
          MouseClick($x, $y)
     ;Else
          ;could do an else, but its not required
     EndIf
WEnd

THANKS! It worked. I truly appreciate it!

This is just a side quesiton and not really important but it would be nice to have, is there a way to check a range of pixels? i.e. 30, 200 to 50, 300 or something like that?

Maybe something like PixelChecksum?

Or perhaps

For $x = 30 To 50
    For $y = 200 To 300
        If PixelGetColor($x, $y) = 0xFF0000 Then MsgBox(0, "", "Pixel found at :" & $x & ", " & $y)
    Next
Next

Alzo...

Check out the PixelSearch() function, which searches a defined rectangle for a color:

$Color = 0xFF0000
$XYResult = PixelSearch(30, 200, 50, 300, $Color)
If @error Then
     MsgBox(16, "Failed", "Color " & $Color & " not found.")
Else
     MsgBox(64, "Success", "Found color " & $Color & " at x=" & $XYResult[0] & ", y=" & $XYResult[1])
EndIf

Edit: Tweak... thanks Daniel W.

You missed the ")" after $Color

Works great, thanks guys!
