Kinematics: predict projectile path

Now, is it possible to move the last point, on the line with a % input?
100% end , 0% line orgin
Time input seems to modify length relative to other points.

Actually, thats perfect !!! Much better than my attempt at faking it. You're the best. Thanks a lot! 👍

Works great. Thank you !

Any idea how to use this in Local Space and path visual interact with obstacles?
