finding the right pixel in a game

[solidacid]

hey.

im working on a script that collects data from a game for further processing(a big database on my website).

it's a script that "plays" the singleplayer version of Diablo II: lord of destrution

and collects data while doing it,

it repeatedly kills certain monsters("Mobs") in the game and harvests data like: what they drop, how frequently they drop cetain things, the estimated value of each kill(in terms of items). while also calculating things like: mob health, mob resistance to certain attacks, while logging it all to several .ini files.

the script will be running for a cuple of weeks on several of my spare Pc's(all build from old computer parts i got for free muttley )

to identify what items drop, i made a mod for the game(blizzard made that possible 2 weeks ago ) that colors the text of certain item groups(like swords red, shields blue, gems and runes purple and so on.)

now, what i need help with is the "looting" part of my script.

in diablo dropped items show up as text, but ONLY when mousing over them or when holding down ALT

when i DON'T hold down ALT dropped items look like this:

when i DO hold down ALT dropped tems look like this:

i need to pick up all items that have Red or Purple(the mod is not fully done yet, i still need to adjust the last few things to be red and purple) text,

i tried some different approaches, i tried this:

expandcollapse popup

HotKeySet("{END}", "Terminate")
Opt("MouseCoordMode", 0)
WinActivate("Diablo II")
mousemove(1,1)
WinSetOnTop("Diablo II", "Diablo II", 1)
Func Terminate()
    Exit 0
    Send("{ALTUP}")
EndFunc

;Variabler:
$loots = 50 ;hvor mange gange den skal kigge efter ting
$lootcolor = 0xFe31Fe; farven på items der skal lootes exam: 0x42fb64
$left = 340 ;hvor scanningen skal starte
$top = 300 ;hvor scanningen skal starte
$right = 440 ;hvor scanningen skal slutte
$botton = 400 ;hvor scanningen skal slutte
$variation = 100 ;hvor langt fra den søgte farve må være fra den angivede
$step = 0 ;hvor mange pixels der skal springes over


for $i = 1 to $loots
    WinWaitActive("Diablo II")
    send("{ALTDOWN}")
    sleep(1)
    $result = PixelSearch($left,$top,$right,$botton,$lootcolor,$variation,$step) ;søg efter pixels med den rigtide farve
    if @error = 1 Then ;er farven fundet?
        msgbox(0, "fejl", "farven blev slet ikke fundet", 3000) ; nej, smid en fejl-besked      
    Else ;farven er fundet (yay :D)
    send("{ALTUP}")
        $confirm = PixelSearch($left,$top,$right,$botton,$lootcolor,$variation,$step) ;søg efter farven, er det samme pixel?
        if @error = 1 Then ;er farven bekræftet?
            if $result[0] = $confirm[0] Then ;passer koordinaterne?
                if $result[1] = $confirm[1] Then ;passer koordinaterne?
                    beep(500, 50)
                    send("{ALTDOWN}") ;hold "ALT" nede for at få item tooltippet frem
                    mousemove($confirm[0],$confirm[1]) ;bevæg musen til tingen
                    mouseclick("left") ;klik på den (saml den op)
                    send("{ALTUP}")
                EndIf
            endif
            $error = "item IKKE bekræftet" ; nej,
        Else
;msgbox(0, "fejl", "farven blev ikke fundet anden gang", 3000)
        endif
    endif
next

(SORRY FOR DANISH COMMENTS)

it SHOULD hold down ALT and do a pixelseach for the chosen color($lootcolor). if it finds the color release ALT an check if it's still there.

if it is, move the mouse there and click.

repeat about 10 times

one of the problems is that even when i use the eyedropper tool in photoshop to get the color of the red text so i can put it in my script, the script does not find the color

i hope you can help me make a working script.

(wow that took a long time to write)

Before ask for pixelsearch go to frequently asked questions and read the 7reply : http://www.autoitscript.com/forum/index.php?showtopic=37289

Thanks !

Before ask for pixelsearch

im not asking HOW to do a pixelseach, thats easy.

im asking for help making my script do what i want it to,

the script does run and there is no errors, im just not getting the desired effect.

and im trying to igure out how to get the red texts color in hex. i tried using the eyedropper from photoshop(wich conveniently is outputted as hex) but the program needs a variation of 500(!!!) to even find the color.

so, my question is:

how do i get the correct color of the red text? and get my program to actually find it?

[Smiley357]

My suggestion would be to use the AutoIt Window Info hold alt down and move over the red text and see what color it is. Then in pixelsearch have the shade-variation around 5 and keep moving up until it detects it. But im still learning myself. Good luck

i think i found the reason my script isn't working. i created a small scrift to check the color of the pixel under the mouse, i tested it in paint and it worked great. so, i tried holding the mouse still over a big (consistently)red blob, my programm outputted a light green(?!) i moved the mouse 1 pixel(still in the red area) and it outputted blue instead?

im getting incorrect colors from diablo, any ideas muttley what might be the problem? and how to solve it?

im sure that if i find out how to get the right colors from diablo, i can make the script work on my own

PixelChecksum

... by the way, it's not polite at all to repeatedly bump your post

lol i use the official version of this bot (mmbot).

[solidacid]

it's not polite at all to repeatedly bump your post

i know, and im sorry but i really need this to work.

how exacly is a checksum going to help me?

PixelChecksum only returns a checksum(for checking if the picture changed)

it does not return the color of the pixel.

lol i use the official version of this bot (mmbot).

mmbot is for online use and it uses illegal hacks,

im not interested in "cheating" in the online version.

also, lots of people have been banned for using mmbot.

all i need to know is:

how do i get the actual color of a certain pixel? when i mouse over a pixel that i know is red, autoit reads it as green, move the mouse 1 pixel to another pixel of the same color and autoit reads that as blue and so on

OK - maybe PixelChecksum is not the best idea for you - I've been tricked by this:

how do i get the actual color of a certain pixel? when i mouse over a pixel that i know is red, autoit reads it as green, move the mouse 1 pixel to another pixel of the same color and autoit reads that as blue and so on

I guess your problem stays in this: You're sending "Alt down" and you look for a TEXT color, you find it (maybe) and after that you send "Alt Up" and you want to confirm the color ... WHICH COLOR do you want to confirm? the text color? - it's gone once you release Alt and the same pixel's color will be different (text/no text).
