[PD] setX in [mass]

[Alexandros Drymonitis]

What I actually wanna do is create a rectangle with coordinates (0, 0),
which grows in width. For example, it starts with dimensions (1, 0.5) and
grows to (1.5, 0.5). In order to make it look like it grows only towards
one direction (to the right), I give it an offset on the x axis, so new
coordinates are something like (0.15, 0). I then give random coordinates
(x, y) with physical modeling, but what happens is that the rectangle goes
first back to (0, 0) and then to (x, y), which looks a bit clumsy. I
actually want it to start from the last coordinates (0.15, 0) and go
straight to (x, y), without deviating through (0, 0).
Hope this is clear enough, it's a bit difficult to isolate this specific
part of the patch to attach it to this email. I tried your example, but
still can't really make it work..
FYI, I'm setting the following parameters to [link]: [setK 9, setD 0, setD2
500(
and to [mass]: [setM 10000(

Thanks anyway
