Using computers to cheat at the perfect circle game

[jpnix]

There is a fun game going around that has you attempt to draw a perfect circle with either your finger on mobile or mouse pointer on your machine and get points based on accuracy and speed.

Me being me I wanted to find a repeatable and consistent way to get high scores with my circle drawings and figured a computer could do it pretty well, so lets trick a computer into doing it for us.

First step is to record the mouse cursor and hold movement coordinates so that they could be repeated over and over on the game screen. I initially sought out to do this in xdotool as i've done something similar before with it and I just love it but after some web digging I cam across XNee

With Knee I didn't have to write anything or use xdotool I could simply perform a function after running it and save the output to a file, exactly how I wanted.

Now that I have a tool that could do the needful I set off to find a perfect circle




After that we can run xnee to capture our coordinates while tracing this perfect circle and store those actions in a file to recall repeatedly.

Record the tracing of the circle.

$ sleep 4;  cnee --record --mouse --keyboard -o cnee.data

Perform the recorded steps

cnee --replay -f cnee.data -v -e /dev/null -ns

Now the script can be ran and get a 93% accuracy every single time.
