Possibly worth trying:

a possible hint to a solution: A lot of people use particles for chains and ropes between collars or cuffs and poles for bdsm things

If there is physics support for a hanging rope (or chain or cord or elastic band) connected at both ends,  I have never seen it, and I've looked for it many times, for swings and ropes connecting my sailboat to the pier, etc.

If someone else has seen this work, let us know!  Maybe there's some way to do it with "mesh" objects these days.

Flexiprims only connect at one end, and you can't chain them together.  Chains of links don't work because, well, physics is pretty bad -- they tend to explode or do other strange things.

You could fake the appearance of a cord by having a photograph of a hanging cord on a flat prim, and very cleverly stretching and rotating the prim -- but that would only work if you knew where both ends of the cord should be, and,  as you either know or will find out soon,   the avatar and attachments are all managed on the CLIENT, and the SERVER only knows where the avatar center of mass is,  let alone where an arm is, or a hand, or a held object like a handset.

And, there is no way to have a held handset report its region coordinates, because it doesn't know itself where it is. If you ask for llGetPos() or something, you get the coordinates of the center of mass of the avatar.   Sigh.

So,  basically, no, there is no good way to have anything that looks like a realistic cord connecting two objects,  at all (unless mesh does it), let alone one object that is an attachment and another object that is not an attachment, that I know of.

Hi,

I am wondering if it is possible to realize this effect in OpenSim:
1. A handset connects to the telephone via a cord.
2. The cord must always at one end connect to the headphone and at another end to the telephone.
3. The user can pick up the handset (NOT the entire telephone set) and when a handset is picked up, the cord remains connecting to the handset and the telephone.


Is it too ambitious?

Thanks!

Cheers,
Han
