Small bundle of (possibly silly) questions.

Recommended Posts

BitOfHope

Alright, so I've done some googling to try and find my answer, but no luck.

I've got a few questions, hopefully they're not to stupid. ;D

1. Is it possible to use PixelSearch(or anything else) to lock onto a pixel/area that is located?

Example: I search for a specific color and PixelSearch finds it. Is it possible to literally lock onto that pixel? Even if it was moving? I highly doubt that it's possible, but I still feel the need to ask.

2. In my previous topic:

(For anybody willing to help I won't include my other post in this post to save some space.)

I was given some help with dividing the screen in half...

So I was wondering if it would be possible to divide the screen up into more sections instead of just half? Maybe 4ths? A dozen? A hundred? Even a thousand?

3. Assuming question 2 was possible, and say that the screen was divided into 100 even sections, is there a third party program that could be used to display a grid showing where each section was?

I have more questions, but those all depend on what (if anything) is possible.

Hopefully somebody can point me in the right direction. Thanks :)

I can only address #2 and #3. You do not need an outside program to draw gridlines. Below is an example of your screen getting split up in to 100 equal sections. Press the ESC key to exit.

#include <WinAPI.au3>
#include <WindowsConstants.au3>
#include <FontConstants.au3>
#NoTrayIcon

$width = @DesktopWidth
$height = @DesktopHeight

Global $tRECT, $hFont, $hOldFont, $hDC

HotKeySet("{ESC}", "_Exit")

$tRECT = DllStructCreate($tagRect)
DllStructSetData($tRECT, "Left", 5)
DllStructSetData($tRECT, "Top", 5)
DllStructSetData($tRECT, "Right", 250)
DllStructSetData($tRECT, "Bottom", 50)

$hDC = _WinAPI_GetDC(0)
$hFont = _WinAPI_CreateFont(50, 0, 0, 0, 400, False, False, False, $DEFAULT_CHARSET, _
        $OUT_DEFAULT_PRECIS, $CLIP_DEFAULT_PRECIS, $DEFAULT_QUALITY, 0, 'Arial')
$hOldFont = _WinAPI_SelectObject($hDC, $hFont)

_WinAPI_SetTextColor($hDC, 0x0000FF)
_WinAPI_SetBkColor($hDC, 0x000000)

While 1
    For $i = 1 To 100 step 1
    _WinAPI_DrawLine($hDC, $width / 100 * $i, 0, $width / 100 * $i, $height)
    Next
    Sleep(100)
WEnd

Func _Exit()
    _WinAPI_SelectObject($hDC, $hOldFont)
    _WinAPI_DeleteObject($hFont)
    _WinAPI_ReleaseDC(0, $hDC)
    _WinAPI_InvalidateRect(0, 0)
    $tRECT = 0
    Exit
EndFunc   ;==>_Exit

#include <ByteMe.au3>

BitOfHope,

There is nothing native in AutoIt to let you "lock on" to a particular pixel. You would have to write a function to do it and the speed of the various Pixel* functions are such that I doubt you could follow that particular pixel if it were moving with any speed. But I am quite prepared to be proved wrong on that last point. ;)

What sort of "lock on and follow" behaviour were you contemplating? :)

Thanks, it works great and after 10 minutes of googling I was able to start understanding some of the parts I didn't understand ;D

Well, long story short: At work I have times of 'sit there and wait' which last anywhere from 2 minutes to 2 hours. So I like to keep myself busy, but I can't hop onto xbox live or anything without getting interrupted(which I find highly annoying). Autoit is great for keeping me busy.

As silly as it may sound, I'm doing little exercises with pictures/colors (sometimes I just use my desktop icons) to test what is possible. It's really simple: Put the color over at 'this part of my screen' and then click and drag it over to 'this part'. Then try and see if the script will find the same color again. So I was hoping there would be an actual way to 'lock on' to that color(pixel?). But I guess not, so I'll have to use other methods. That's what the grid is for. I was thinking "Hey, what if the screen was divided up into tons of little boxes? Then I could place my desktop icon in 'gridbox1' so then when the script detects that color(desktop icon) in 'gridbox1' it could make it's own action for that specific grid. Then if it finds that color in 'gridbox14' it could do something slightly different..." etc etc.

Would that not work the way I'm imagining it? ;)

I figure it's as good as any other way to learn new things.

Edit: Sorry for the doublepost.

BitOfHope,

Not silly at all - a good way of learning how to use AutoIt. :)

You might find this of interest. I have not used it myself, but it seems to do quite a lot of what you want - locating an image on screen for example. ;)

You can't "lock on" to a moving pixel for the reason that the pixel itself isn't moving. Let's say you have a red pixel at 50,50 and it moves to 50,51. It doesn't really "move"; the pixel at 50,50 goes dark (or to another color) and the pixel at 50,51 that was previously dark is now illuminated to red. But it's a different pixel.
