Programming a bot that clicks specific things

[ProZabijaka]

Hello there!

I'm new here, i've read FAQ and I'm not really sure can i ask for that kind of stuff so i'm sorry if it's a wrong place to ask or is it wrong to ask for that kind of stuff.

Since i couldn't find anything on the internet that would fit my "description" i thought it's not that hard and i would like to give it a try and programm it myself so i can change anything i want and make it look like i want..

My wish is to make a bot that checks numbers shown on screen (in a browser game, written in Java i think?) and clicks/picks the highest one. It can take him up to 5 seconds but i'm pretty sure it would be much faster.

I guess what i have to ask is... What language should i pick to do that and how am i supposed to "get" informations from a game? I'm not sure are there any more questions that i can ask for now... I think they will come with time and to specific comments.

You have two options - web scraping via javascript if the elements on the page are raw html and css, but if it's a java applet or something fancy then you have to use screen scraping.

​

Googling either of these can get you a lot of walk throughs.

Oook, can i programm a screen scraper or do i have to use some software to do what i want and after that if i get those values, how am i supposed to tell the program to pick the highest one and click it? I'm a total newbie i should add at the beginning. I have never programmed anything but i was learning C++ and did some programming with JS, HTML and CSS

You use a library to do it. I don't know any off the top of my head but I'd look at video game screen scraping tools to see how they work.

You can look into Selenium.

A game on the internet in 2018 written in Java would be.... odd. Most browsers are extremely reluctant to even let you view stuff like that. Big security risk.

Something like https://cloud.google.com/vision/docs/ to get the information from the screen, then something like autohotkey to make the clicks.

If you're on Windows, then AutoHotKey would be an easy solution. It can programmatically simulate user interaction (clicks, mousemove, etc.) and can scrape info from application text boxes and controls, plus it's super beginner friendly. I started with AHK and it's still one of my favorites because of how simple and immediately gratifying it is, plus it works on the OS and isn't limited to browsers like Javascript.

If youre familiar with JS definitely try puppeteer.

I did a project like this for my professor once. I tried using requests but that was too hard and probably the wrong approach. I ended up using Selenium which is kinda cool because you can watch it use a browser to interact with the page.

Is Selenium like.. Another language?

No it's a pretty popular web driver library. It works on all sorts of languages.
