But your code has:
moving_circle.move(P_to_R/P_to_E, E_to_R/P_to_E)
so won't that move the circle and change what:
moving_circle.getCenter()
returns?
Yes, moving the circle changes the value of moving_circle.getCenter(). The problem is
interpreting the output. 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.
The initial point won't change, but that's just where the circle was
originally.
Are you sure that it doesn't change? Have you printed out
moving_circle.getCenter().getX() and moving_circle.getCenter().getY()
and seen that they aren't changing?
Distinguish between the circle's center and the initial center point I declared. My
program can output the former, but it's in a format that I don't understand:
<graphics.Point object at 0x0000013E0D263668>.
As for the initial center point (I'll call it moving_circle_*initial*_center
instead), it won't change at all throughout the program execution.
I need to know the x- and y-coordinates of moving_circle.getCenter() at any
point in time. I can't use the center of the circle *before* it started moving,
because that value is static (in other words,
moving_circle_initial_center.getX() and moving_circle_initial_center.getY()
never change).
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.
