Pixelgetcolor Error?

[Gogeta70]

Ok, i'm making a simple auto-pot bot for a game because when i'm fighting i'm constantly mashing the health pot hotkey. It works fine except for one big issue. When i use pixelgetcolor on my health bar, it returns black. So, i had autoit take a 100 pixel box of colors from the top left of the game screen and write each hex value to a file. Then i made a simple PHP script to convert that into an actual image. This is what pixelgetcolor is returning:

Any ideas why this might happen?

I think the problem is the makers of the game dont want you cheating and having an unfair advantage to anyone else.

You should also take a look at this.

[Gogeta70]

It's not an unfair advantage. Anyone else can download AutoIt and make a bot as well. Saying that the lack of knowledge is the unfair advantage doesn't work either, considering i learned the AutoIt language in about 30 minutes.

All other players have the same resources i do to do the exact same thing i'm trying to do, so don't feed me that bullshit.

haha

Nice the way they prohibit the use of computers in an online game.

Classic.

Morse code anyone?

I encounterd alot of this behavior while creating screenreading tools on some maschine configurations.

I recommend for healthbar reading the proper memtable and checking for the places in the client of your game. If that is over your abilities, you need your application to work in window-mode or you need to hook into its DX-calls (which should be over your abilities then aswell).

If you still get the black-problem in windowed mode your maschine might use SLI or XFire which result in a 'flickering' while reading from videomem. In that case you could write your own checkpixel like i finaly did that gets your proper results. Or you just modify the existing one like this

Func checkpixel(Const $xpos, Const $ypos)
    $cptimer = TimerInit()
    Local $color1 = 0, $i = 0
    While $color1 = 0 And $i < 3
        $color1 = PixelGetColor($xpos, $ypos)
        If $color1 = 0 Then Sleep(1)
        $i += 1
    WEnd
;~  ConsoleWrite('Color = '&$color1& ' ,Trys = '&$i&@CRLF)
    Return $color1
EndFunc   ;==>checkpixel

This will kill your overall performance but from what i get just reading a bar or checking on a button this will do.

If you are about to get into 'real' bot-coding your problems will be far more advanced, so will your skill.

Thank you for your input. As far as i know, AutoIt cannot access the memory space of other programs. I'm also a PHP coder, but PHP cannot really do that either. The reason i turned to AutoIt is because i'm still learning C++ and can't do something like this with it yet.

I'm pretty sure it's not an SLI error considering i'm only using a single nVidia (nVidia GeForce FX 5500), and i don't use xfire.

Also, like i said, i took a small 100x100 pixel square from the top left corner of the screen and had autoit read every pixel, surely some of them would've returned something other than black. Regardless, i'll try your function anyway.

Thanks again.
