unity 2021:

public void SetSimplices(int[] simplices, SimplexCounts counts)
{
    this.simplices.CopyFrom(simplices);

how to convert this line to 2022?

I'm having a heck of a time. I would like to have four ropes, stationary at the top, and linked together at the bottom. When something hits one rope they should all react because of the bottom link. Is there an example of such a setup I could look at?

I'm not sure where to start here, as I'm unable to identify what the issue actually is.

I'm working on a sailing system -- and it works well with a single sail.

I'm working on an object with three cloth blueprints active, and it crashes instantly every time I attempt to build or run from editor. No error messages are produced. This happens if I have three separate cloth blueprints, or the same blueprint duplicated twice. (All three are parented to the same solver in all cases.)

Doesn't seem to be performance related, as they are relatively simple bp's. (140 particles each). Two will run at around 200fps, but adding the third, even after runtime will always result in a crash, regardless of which of the three is activated. i.e. any two is fine, any three always fully crashes unity.

Any thoughts to where I should begin to sort out what's causing this?

So my player can grap the rope where he want. 
I want to use the left/right cursors to add velocity to the rope to swing it left, right. 

What is the correct way to do this? 
If I add left or right velocity to the current, or all particles than the rope movement will be not right. 
I mean I have rope and I have chain from metal what is heavy, but the rope not moving correctly. Correct means that the all particle stay in 1 line only. So not flexible at all.

1, how can move all the particle?
2, how can remove the flexibility of the rope, so I want a hard rope

I'd like to disable and re-enable a softbody with a skeleton, but when I re-enable it, the skin weights don't work correctly anymore. The skeleton's animation no longer influences the softbody at all. The same thing happens when I disable and re-enable the Obi Softbody Skinner component so I guess it has something to do with that. Is there some way to do this properly?

I am getting a few errors when trying to use Obi in a project with Entities.

Hello!

I'm trying to create a rope that the user would be able to grab and interact with in VR from basically any place, not only the start and end. So I figured the simples way to do that would be to add a bunch of rigidbodies and connect them via ropes. Similar to the RopeNet example. I also need to sync that over the network, that's another reason I used a couple of rigidbodies, they are very simple to sync over Fusion with NetworkObject.

What I did is I took the RopeNet example script and made my own that generates the same thing, but in a line instead of a net and adds a couple of components for interactivity to the rigidbody objects.

Since it should still look like a rope and not a buoy line, these objects should be reasonably small (the smaller the better) and with a pretty low distance between them for usability. But when I make the objects small, the ropes start to detach and jitter (the RopeNet example does that too, on the top ones).

Attached a low fps gif of the jitter (it is way more spazzy in Unity).

Can anybody help me remove the jitter or point me in the right direction if my approach is flawed?

Hi

i managed to get custom physics working with OnBeginStep and it is working nicely
now the visuals are lagging behind, where is that updated?

as you can see in the video the visual representation of the softbody lags behind the wheels and camera, both updated in OnBeginStep

thanks

Hi, 

I want to make a rope passing through some set of points, let's say, p1, p2, p3, p4. 
but I want its original length is |p1-p2|. I want rope is full stretched and tight when rope end point is at p4.
I setup rope on edit mode, and when I play, rope passes through my desired points.

My desire is when rope is released from p4 it must be relaxed and gets to its original length of |p1-p2|.

When I setup control points to make rope pass through all points, when it is released it keeps its length |p1-p2| + |p2-p3| + |p3-p4|. Hoverer I want it length to be |p1-p2|

How can I achieve this?

We are developing a crane simulation based on some our own R&D and currently experiencing jitter when we try to move the object attached to the crane ropes. It works very well when we use a single rope but when we attach 4 ropes, it jitters. Video is available for reference.

We developed the simulations before similar to that but those were on old backend, now we are using the latest 6.5 OBI with burst backend.

All 4 ropes are using the same blue print (only displaced by the game object transform in unity, equally). At top ropes are attached with single point as static attachment and at bottom towards the load (red box object) they are dynamically attached. It is interesting that the jitter mostly occurs at high speed and usually its higher when we are using 4 ropes (on a single rope it is very minimal and can be ignore)

Any advice on how to overcome or minimize this jitter is high appreciated. Thanks in advance
