How to implement OCR/captcha solver?

04 Aug 2017, 23:00

Hello all, I've been using a script that I made months ago for a game that I play. The script itself is very very simple. It's something along the lines of:
Loop{
attack commands
movement commands
}

However, I still have to be physically present (or at least check in every few minutes) because this game allows players to do a "bot check" on other players. I then have about 30s to fill out the captcha numbers or I get banned.

I want to automate this process. I did a little bit of digging around and I found out that what I was looking for was OCR. How do I implement this into my ahk script?

Additional info:
I found a captcha solver on YouTube which will solve captchas that you have a picture of in a specified folder. In order to use this, my script would have to take the following steps:
-detect the captcha
-take a screenshot
-crop out the captcha portion? (The captcha is always in the same position on the screen and is always the same size)
-save that picture (maybe via paint?) in the specified captcha folder
-run the program
-retrieve the numbers
-fill out the captcha in game
-hit "ok" on the captcha window in game
-reset my script

Would this be the best way to go about it? What are the alternatives?

I second this, I have a similar application for OCR and would prefer to implement it into a AHK script.

Anyone around that can point us in the right direction?

Probably not worth the effort, if it's even possible.

I did this once for a game called runescape, it is somewhat easy if the text is always the same, in that game it was.

I saved all the text to png files 0-9 a-z, I then scanned the screen for every one of those files, saving each location in an array, then determined their position from eachother to piece the words together.
So if I found the letter T and A and the distance bewteen their x/y is less than 3 etc, then they are part of a word, if position X of a is smaller then X of T then a goes before T.

If the text rotates or scales it may be very difficult if not impossible though.
Some of my AHK programs: Platformer Game - Langton's Ant - Raycast light/Pixel Water - Creating HD map of any game
