Get rope speed, velocity and angle

[lacasrac]

What is the best way to get the rope swing  speed, velocity? Also get an angle of two particle?

private Vector3 GetVelocity()
{
    int index = 0;
    int actorIndex = 0; //solver.actors[index].solverIndices.Count() / 2;
    var solverIndex = solver.actors[index].solverIndices[actorIndex];
    Vector3 velocity = solver.velocities[solverIndex];
    Debug.Log("velocity v3 " + name + " " + velocity + " " + solverIndex);
    return velocity;
}

What is the probleme with this code? I added the rope from code, and I want to get the velocity of the rope's half height's particle. How can I do that?
I only get 0 always.

{
    int index = 0;
    int actorIndex = 0; //solver.actors[index].solverIndices.Count() / 2;
    var solverIndex = solver.actors[index].solverIndices[actorIndex];
    Vector3 velocity = solver.velocities[solverIndex];
    Debug.Log("velocity v3 " + name + " " + velocity + " " + solverIndex);
    return velocity;
}

private Vector3 GetVelocity()
{
    var index = _rope.activeParticleCount - 1;
    var solverIndex = _rope.solverIndices[index];
    return solver.velocities[solverIndex];
}


this is working, but I don't know this is good or not?
