It's not strictly true that you _have to_ store the result

But your code has:

so won't that move the circle and change what:

returns?
Yes, moving the circle changes the value of moving_circle.getCenter(). The problem is

Try this in an interactive session:

The moving circle moves towards the stationary one. However, when the moving
