Help Oscillations when setting cable lengths, probably due to dynamics

[rohit_dhak]

Setting the stretching scale to 0.1 will tell the rope to try and keep their length at 10% of their rest length. Should be left to 1 (100%) unless you're going for some special effect.

If your ropes are sagging, either:

- Use more substeps (10-15 is completely fine). This will ensure ropes reach their target rest length during simulation. The manual contains an in-depth explanation of how iterations and substeps affect simulation quality: http://obi.virtualmethodstudio.com/manua...gence.html

- Decrease rope resolution. Less constraints will result in faster convergence and less spurious compliance (that is, less elastic ropes). A resolution of 0.6 means particles will slightly overlap each other, which means there's a lot of particles. Since your ropes are very long, that will require a rather high amount of substeps for the simulation to be accurate.

You can combine both: use lower-resolution ropes with more substeps.

Note you can use surface collisions in case your rope resolution needs to be low and gaps appear in-between particles.

kind regards,

So I am noticing one thing which I would like to get clarified.

I have following changes:
Sample code for 1 cable:

Code:

    public void set_c2()
    {
        if (c2_len > c2_control_ip + cable_threshold)
        {
            cursor_2.ChangeLength(c2_len - speed * time_dt/10);
        }

        else if(c2_len < c2_control_ip - cable_threshold)
        {
            cursor_2.ChangeLength(c2_len + speed * time_dt/10);
        }

        else
        {
            Debug.Log("Current Length and Control input are the same for Cable 2");
        }
       
    }

cable_threshold = 0.01f
time_dt (Timestep) = 0.01

Cable Obi Fixed updater substeps = 30

The thing that I am not understanding is,

   

I am giving the condition to get c2_len which is rope2.CalculateLength() set to the control input c2_control_ip
However when I logged the restLength, c2_len and c2_control_ip I saw that the c2_len is trying to set to restLength instead of c2_control_ip

Am I misunderstanding something?
