Hello I need some help. I have added a rocket as a 2D image inside a Plotting Panel. The rocket moves along the x axis in the positive direction with some variable speed v. A soon as the velocity turns negative I would like the rocket image to flip so as to point always in the direction of movement. I have tried with the transformation editor in the Transform element of the popup panel. In it I see an item called Matrix Transf. It is a 2*3 matrix and I have not been able to make it work. I guess at some point I would need to insert a -1 for a reflection in the y axis, in the form Math.signum(v) or so. Can somebody help me?. Thanks a lot.
