I understand that you want to create a circle that you can rotate by the X, Y and Z axis, but unfortunately I'm not used to use vectors and stuff like that, so the best thing I can do to help is the code for checking if the player is inside the circle (although any possible way to check it is to create a "box" where the limits are the circle's limits).
