The command gives <graphics.Point object at 0x0000013E0D263668>, and I don't know how to determine the x-coordinate of the center from that output. This is my problem. I can't translate the .getCenter() output to Cartesian coordinates.

I have already told you how to get the x and y coordinates.

moving_circle.getCenter() returns the centre as a Point object.

That Point object has .getX() and .getY() methods, which return the x 
and y coordinates respectively.
