Friday Night Funkin' AutoPlayer
This is a python script I made inspired by @CodeBullet 's similar script for Guitar Hero.
I am probably not going to release it as there are many issues with it, mainly with the way I get the position of the notes (the window size needs to be similar to the one I recorded it in due to constants (trol)).
It works by taking a screenshot of the bottom-right corner of the screen (cropped to fit the arrows better) and determining if there is a specific color on the bottom of the arrows. If it finds the specific color, it will start holding down the key. If the color isn't found it will stop holding down the key (if it was already holding it down).
This works very well for most notes, but with the notes you have to hold, I didn't get the color values for when the arrows keys are being pressed (I believe is the reason), so it is a tad finicky.
