PixelGetColor() is always returning zero in-game

[randomdude]

Hi I'm having problems getting desired results from PixelGetColor() while using it in a fullscreen game. It's always returning 0. The strange thing is, sometimes after starting the script it works PERFECTLY (returning non-zero values) as desired but then when it stops working, it will not work again until you terminate it and start it over. Most times it will not work at all.

I've tried many combinations with different values for Opt("PixelCoordMode", X) and Opt("MouseCoordMode", X)... No reliable results. Though I can say that the times that it DID work, both those parameters were set to 1.

Things to note:

1. I've downloaded the latest AutoIt (downloaded and installed today)

2. I'm running Vista with Aero disabled

3. I'm running a game that uses Game Guard v1195

4. I've compiled my AutoIt code and run it in 'Administrative mode'

5. I'm a software engineer but have no windows development background

6. I've been scouring the forums and the documentation for the past 5 hours and gotten nowhere.

7. http://www.autoitscript.com/forum/index.php?showtopic=77616 is a similar post to this but no answer.

Here is the code I'm using to test the functionality:

HotKeySet("^!a", "GetInfo")
HotKeySet("^!k", "Terminate")

While 1
    Sleep(100)
WEnd


Func GetInfo()
    $pos = MouseGetPos()
    $color = PixelGetColor($pos[0], $pos[1])
    MsgBox(0, "Mouse x,y:", $pos[0] & "," & $pos[1] & "  color = " & Hex($color,6))
EndFunc

Func Terminate()
    Exit 0
EndFunc

Thank you, in advance.

Hi randomdude,

1st Welcome to the AutoIt Forums!

Some of the following tips may not apply to you, but it may make your life a bit easier here on the forum in the future.

CODE

• Did you know that we have an awesome search feature?

  You can find many answers to your current questions, just by typing in the right search patterns.

• A suggestion is to use the Advanced Search mode:

• Type your specific search term in quotes.
• Click the forum you want to search in (the one most likely to have your information would generally be the Example Script forum and or the General Help and Support Forum).
• Click on "Search titles only" radio button.
• Click perform search.

The above will help you narrow down your searches and prevent you from unneccesarily posting a new thread.

[*]Also, you should try to read the Sticky posts that are at the top of each of the AutoIt Forums you enter such as:

• FAQs (Frequently Asked Questions)

• Are my AutoIt EXEs really infected? (About false positives and what to do if you may encounter one)

[*]Keep in mind, the help file will be your best friend, however you may find some of the tutorials written by some of our elite forum members helpful.

• Valuaters Interactive AutoIt 1-2-3 tutorial

• LxPs Learning to script with AutoIt3

[*]Forum Etiquette:

• Making a new thread:
  • Use the Search feature first to see if your question has already been answered.
  • Look in the help file as well before even thinking of posting (When what you want could be obtained by simply reading the help file, you don't generally get a good response from your AutoIt community).
  • Titles are very important here. 1 word titles or titles like "help me", "write something for me", "I'm a noob" etc... aren't tolerated.
  • Make sure you are posting in the correct forum:
    • General Help and Support:
      • This forum is for AutoIt related support questions only. If you have a question related to another language, or nothing at all to do with AutoIt then you need to post in the chat forum, or in that languages perspective forum.
    • Example Script:
      • This forum is for AutoIt scripts/executables only.
      • Source code is preferred but not necessary, you do have the right to just post the binary of your project if you wish.
      • Please don't post questions in this forum unless it's directly related to a thread already existing.
  • Use common sense when creating a new thread.

    Ask yourself if the title is descriptive enough to even interest someone (preferably those that know what they are talking about) to even look at your thread, let alone reply in it.

  • Think about how it would show in the search feature if someone were to look for something just like you are looking for (think of the keywords you used yourself and obviously didn't find anything (because we know you used the search feature ) and use those types of keywords in your title as well).
• Thread content:
  • Be descriptive with your query. (Make sure we actually know what you want to do).
  • Show you've made an effort in coding what you want (provide the reproducer code (generally no more than 50 lines as people lose interest in debugging someones script for free)).
  • Don't talk in ebonics. A lot of the forum members are adults, and a lot of them know how to help you, but talk like a child, you'll be treated as such.
  • Don't ask for help making keyloggers, spam (even if it's to do as a prank), or anything that can be thought of as malicious. You'll more than likely have the thread locked by a moderator, and take a bashing from your fellow AutoIt community.
  • When posting code, use code boxes. This can be accomplished by using [code ]<content here>[/code ] (No spaces between the brackets []).

    Using code boxes will keep the indentation and make it easier to read for others to help you.

• Bumping your threads:
  • Use common courtesy here.

    Keep in mind every time you bump your thread to the top of the forum, you knock the other threads down a notch.

    Everyone posting for help has just as much right for their threads to get read as you do.

    Because of that, do not bump your post more than once in a 24 hour period.

    A Bump is simply posting in your thread with nothing that pertains to your query with the sole purpose of moving it up.

    Deleting previous bumps, and posting new ones is not tolerated, and the moderators can find those deletions, so do yourself a favor and don't cross that line >_< .

• Rude or obnoxious content:

  This falls pretty much under the common sense thing. If you use it (common sense) before posting, you won't have issues.

  • Don't use foul language, remember, a lot of the community is at work when they read these threads.
  • Don't provoke or instigate an argument with someone.
• Double Posting:
  • It's understood that sometimes there's a lag in the system, and sometimes people don't see their post go up right aways so they post again.

    If this happens to you, simply notify a moderator with the report feature in the post, and politely ask them to delete it.

  • If you're just creating another topic because your original topic is not being answered the way you want or at all, this is not tolerated. You could lose your posting privileges all together over it.
• Non-English languages
  • If English is not your primary language, please make an attempt to interpret (yourself or online) and post that interpretation.

    We have wonderful users from around the world, so after you've done your post in English, back it up with your question also in your native tongue (You may find your answer much quicker using both).

That's it for now, I hope you have a wonderful learning experience, and hope to see you contribute to the community as your knowledge grows.

Bump (It's almost 24 hours, I hope the bump doesn't anger you guys).

I still can't get any results. This is killing me and a crucial ingredient of my overall project. I'd REALLY appreciate any form of guidance.

Also, I've followed instructions in http://www.autoitscript.com/forum/index.php?showtopic=65235 but to no avail. Its still returning zero all the time.

Any ideas? Anyone else having the same problem?

[MortaDella]

Hey, just wanted to tell you that i got the same prob.

I'm trying to write a bot for GuildWars, with the latest AutoIt version an Windows Vista. (is this maybe a OS-Problem?)

It seems that all Pixel functions are working (most cases ~ 95%) in outposts and citys,

but when i try to get them running in a special mission im getting FFFFFF or 000000 values.

This makes intelligent coding almost impossible.

Some users in this forum have the same problems too: http://www.elitepvpers.de.

[cloudkiaDotCom]

will you think that is because of Game Guard? sometime not only get pixel color, even simulate input also failed

[MortaDella]

Dont think its a Game Guard issue; Guild Wars isn't using it at all.

Tvern has/had the same problems: http://www.autoitscript.com/forum/index.ph...;hl=pixel+vista

Ok, here is what i already tried:

-added

#RequireAdmin
Opt("PixelCoordMode", 1)

-added a window handle to the pixelchksum's

-compiled to a exe and run under admin

No solution yet. A few times it runs correctly but in most cases it doesn't.

Edit 1: @Volly... I'm using WinWaitActive("Guild Wars") so i think its active.

Edited October 12, 2008 by MortaDella

[Bert]

perhaps seeing what window is active first before using? Just a thought.

[MortaDella]

Edit 1: @Volly... I'm using WinWaitActive("Guild Wars") so i think its active.

Does nobody have an idea? Vista has become the stadard OS. So whats your plan for the future?

[muncherw]

Vista has become the stadard OS.

Nice
