PixelSearch Problem

8 posts in this topic

Hallo AutoIt Community!

I am now sitting for 4 hours on this stuff, an got no idea left.

Its a simple call of the Pixelseach function which should exit on error.

Dim $KoordNpc[2]

$KoordNpc = PixelSearch(160, 37, 950, 347,  0x8BBC17, 10, 10)
        Sleep(random(783, 1039))    
        
        If @error Then
            exit 0
        EndIf
        
        MouseClick("left", $KoordNpc[0] + random(2,35), $KoordNpc[1] + random(1, 4), 1, $mousespeed)

But instead of this it just leavs me this message:

==> Subscript used with non-Array variable.:

MouseClick("left", $KoordNpc[0], $KoordNpc[1], 1, $mousespeed)

MouseClick("left", $KoordNpc^ ERROR

It seems that every time i call $KoordNpc[0] or $KoordNpc[1] this results in an error.

Has anyone an idea? whats wrong with my script?

Hi MortaDella,

1st Welcome to the AutoIt Forums! :idiot:

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:

[*]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.

[*]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.
    • 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.

Hallo AutoIt Community!

I am now sitting for 4 hours on this stuff, an got no idea left.

Dim $KoordNpc[2]

$KoordNpc = PixelSearch(160, 37, 950, 347,  0x8BBC17, 10, 10)

        If @error Then
            exit 0
        EndIf
        
        MouseClick("left", $KoordNpc[0] + random(2,35), $KoordNpc[1] + random(1, 4), 1, $mousespeed)

But instead of this it just leavs me this message:

It seems that every time i call $KoordNpc[0] or $KoordNpc[1] this results in an error.

Has anyone an idea? whats wrong with my script?

You are testing the @error as set by Sleep(), not the one set by PixelSearch(). Move the Sleep() and do the @error check on the very next line after the PixelSearch() or save @error to a variable if you have to check it later.

This makes sense :) Ty so far, but i still got the prob with PixelSearch.

I already tried to increase the step-range and to reduce the rectangle size, but it didn't worked.

The color shoult be there, tested it with PixelGetColor.

Show how you changed, and what error you're getting... if you moved the Sleep() after the "If @error" then there would be no issue.

Also, you were welcomed in post #2 with forum etiquette listing. Please read the Bump options/rules.

Ok, fixed it :idiot:

Its a simple and stupid mistake:

the "q" key makes the green pixels appear, but there is a delay. so i added a sleep function.

Send("{q DOWN}")
Sleep(random(1039, 1285))
$KoordNpc = PixelSearch(0, 0, @DesktopWidth, @DesktopHeight, "0x8BBC17", 10, 2)

now it works well, thank you very much :)

Oh sorry, i'll keep in mind. >_< Edited by MortaDella

$KoordNpc = PixelSearch(160, 37, 950, 347, 0x8BBC17, 10, 10)

Sleep(random(783, 1039))

If IsArray($KoordNpc) Then

exit 0

Else

MouseClick("left", $KoordNpc[0] + random(2,35), $KoordNpc[1] + random(1, 4), 1, $mousespeed)

Endif

==> Subscript used with non-Array variable.: --> need to check firest if is array...

MouseClick("left", $KoordNpc[0], $KoordNpc[1], 1, $mousespeed)

MouseClick("left", $KoordNpc^ ERROR

Now, teach me how to make a screenshot from a maximized counterstrike window or from opengl and make aimbot for cs. If scanning is slow use speedhack on the script.
