Hello, I am trying to figure this codes and I dont know where to start with javafx. I am trying to get the eyes to follow the cursor as well as to look the opposite direction from the cursor. Either one method will be great help in to understanding javafx. How would you write this in java code/fx. Thanks in advance!

Mouse not in the window, eyes looking ahead. Mouse below the eyes, Mouse above the eyes, eyes looking down. eyes looking up. Mouse to the left of the eyes, Mouse to the right of the eyes eyes looking right. eyes looking left
