      Howdy, I've gone through a lot of au3 forums, and I once had a working Imagesearch script that I got from here.  However, and i'm just totally not sure how but my imagesearch scripts aren't working anymore.
      I'm not new to au3 but i'm not the most experienced with it's syntax/commands.

      Anyways, I've looked over the big threads involving imagesearch.

      Does anyone have a working Imagesearch x64 for win10 that is currently working as of the date with the post.

      Dll's and what not is fine, just when I tell the script to run, I want to be able to find the image on the screen!
      Can't find a working copy so if anyone has one please send it my way lol.

      I've taken all the imagesearch downloads and what not and have played with them but I can't get any of them working on my end, despite others saying they're working.
      Thanks.

      MapIt is a tile world editor.  MapIt was built around the concept of reversing Dragon Warrior map images.  MapIt can take image input and produce a tile and world array.
      MapIt features Unity style dragable labels that adjust property values.

      MapParser is a C++ project that scans images for unique tiles.  MapParser is very fast.  Due to hard drive failure, many bugs were restored b/c I had to rewind many years.  Frustrated with the design, I wrote a new version from the ground up.  This New Version:  AutoIt Front-end, command line controls, and shared with the world; so that I can't lose it again.
      You can toggle the C++ MapParser off to see the difference in speeds between the MapParser CPP verse AutoIt function.  Function is named Scan_Tiles() in AutoIt.  You can also chose to download without MapParser.exe.
      At the moment Scanning a image resets the arrays, but you can add tiles after scanning.
      Images can be added as tiles without scan image at all.  Then configure settings to give your world parameters and manually fill the world data with tile indexes.
      Using the settings you can change tile size after a scan.  Example: you wanted to replace a map with different sized tiles.
      Changing and replacing tile / world data is easy.  B/c tile world editor.

      Hotkeys, I use CTRL+R in image above to signal replace tile action and I use "G" to Get the tile under mouse.
      Hotkeys are not saved to disk and thus are set to default between sessions.
      I might draw the world to pre-rendered surfaces and use them as multi-layer someday.  I do that in my AutoIt, DragonWarrior Remake but I could spend forever unsure what features are important for this.  The DW_Remake has a method of replacing a tile with a tile on two layers.  So you could replace a tree on the first layer with a grass, and a tree in the second layer.  This is all getting very confusing.
      I attempted to write the good code.  If something could be better, please advise.
      Fifth release.  Enjoy.
      For download, videos, and example of created world file data; please visit the MapIt webpage: http://songersoft.com/programming/mapit/mapit_about.phtml
      Special thanks: @AdmiralAlkex, @Melba23, @MrCreatoR
      Main AutoIt source file: Will not run without other Includes and SDL DLLs.
      Last Update: 5/26/2018 3:45 PM EST
      REMOVED CODE BLOCK:  I was informed the this page loaded very slowly, one solution so far has been to remove the 2k lines in the code block.
      When I recieve more feedback from the User I may reduce image size or remove images.
      Next Version Added: $eSETTING_TILE_LAST_PATH I have the weekend, I want to write world layers with aBoard surfaces.
