I'm applying physical modeling to some visuals with pmpd's objects. I'm facing a problem with setting the position of [mass] sending it [setX $1(. [mass] will go to that position indeed, but as soon as I turn [metro] on it tends to go back to the previous position and then return to the position currently set. Even if I send the same position number to [link], it shows the same behavior. The patch is as follows (connections from [metro] and [setX $1( actually go to left inlets):
[line 0 5] [metro 5] [setX $1( | /| / | / | / | / | / | / | / | / | / [link]x[mass]
Any ideas on how to overcome this?
p.s. happy new year!
hello,
after setting a mass position (in a not-physical way), you have to reset forces (in both link and masses).
If you want to set initial position, you better have to use the mass parameter. otherwise, sending force is the "correct" way move masses.

But if I reset them, aren't they going to set their positions to zero? Also, only the second mass is moving, left inlet of [link] is attached to a fixed point, so how can I send force to the second [mass] via [link]? Right inlet won't give any results. What do you mean exactly by 'mass parameter'? Is it for [mass] or [link]? Could you give an example?
Thanks

the initial position (so the reset position) is a parametter that you can set at masses creation : [mass foo 1 1] will be reset at position X

send a force message to the mass inlet : you can have many things connected to a mass inlet...

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

when you set a mass position, the link see the mass quick movement. since D2 is quite high, and D2 is a damping that is opposed to the mass displacement, it will generate a force that send back the mass you displaced.

Not really sure, as my problem is the coordinates of the rectangle and not its size. I'll check your patch thoroughly and try to adapt it to mine. Thanks.

I tried a different approach which seems to work. I reset the objects every time and I send a ramp from 0 to 1, which I multiply by my random coordinates, like so:
[0, 1 200( | [line 0 5] | [link]x[mass] [random] | / | / | / [* ]
