I’m trying on an exercise that need to check whether the new position of an image is correctly reflect in the y-axis.
The basically of this exercise is:
Let say there is an object (a dot) at coordinate (2,3). When I click at a new position, a new image of the original object will be flipped at the new position there. So in order to check whether the flipping object is correctly reflected in y-axis, what should be done? Hope someone could help me out. Thanks in advance.
