If I have a softbody sphere, that I wanted to move by having it roll itself around, how would you code this?

I am currently using a rigidbody and obiRigidbody on the ball (in the example BallPool), and applying AddTorque() but there is no response. 

?

I am creating a game where I destroy a car. In that, I hammer it over and over with various blunt force objects.

What I am wondering is, can ObiSoft, be ideal for this, in that, can it take a dent and retain it? Or, should I look at more classical Mesh Deformation?

Thanks

Hey, I'm facing a weird issue. I have a 3D model with Read/Write setting enabled:



I created a softbody blueprint, added the mesh and generated the volume particles. No issues here:



I create a Obi SoftbodySkinner + ObiSoftbody and suddenly boom:



As you can see, the renderer mesh is readable (first pic). When clicking on "Fix now" I get:

NullReferenceException: Object reference not set to an instance of an object

Obi.ObiSoftbodySkinnerEditor.NonReadableMeshWarning (UnityEngine.Mesh mesh) (at Assets/Obi/Editor/Softbody/ObiSoftbodySkinnerEditor.cs:83)

Like if it was not possible to read. And the softbody object is like the dragon scene one where a different object has the ObiSoftbody with the blueprint:



Any idea? :/

(I apologize if there are any flaws or rudeness due to machine translation.)

When I create a new project with "3D(URP)" and import Obi Fluid, I get an error in the following Shader inspector.
If I build on Windows Intel 64bit environment in this state, the fluid that was normally displayed in Editor will not be rendered.

Hi, I wanted to achieve the visual effect of pumping liquid or air up a rope. To do this, I wrote a script -


public class RopeBump : MonoBehaviour
{
    [SerializeField]
    private ObiRopeBlueprint _obiRopeBlueprint;


    [SerializeField, Range(0.5f, 2f)]
    private float _bumpSpeed = 1;


    [SerializeField]
    private int _framesSkipAnimation;


    private bool _isBumping;


    [Button]
    private async UniTask BumpAsync(float value, bool reverse)
    {
      if (_isBumping)
          return;

      _isBumping = true;
      var thicknesses = _obiRopeBlueprint.path.thicknesses;

      int start = reverse ? thicknesses.Count - 1 : 0;
      int end = reverse ? -1 : thicknesses.Count;
      int step = reverse ? -1 : 1;

      for (int i = start; i != end; i += step)
      {
          float cachedThickness = thicknesses[i];
          float direction = cachedThickness < value ? 1f : -1f;

          while (true)
          {
            thicknesses[i] += _bumpSpeed * direction;

            if ((direction == 1f && thicknesses[i] >= value) || (direction == -1f && thicknesses[i] <= cachedThickness))
            {
                if (direction == -1f)
                  break;

                direction = -1f;
            }

            _obiRopeBlueprint.path.FlushEvents();
            await UniTask.DelayFrame(_framesSkipAnimation);
          }
      }

      for (int i = 0; i < thicknesses.Count; i++)
          thicknesses[i] = 1;

      _isBumping = false;
    }


    private void OnEnable()
    {
      for (int i = 0; i < _obiRopeBlueprint.path.thicknesses.Count; i++)
      {
          _obiRopeBlueprint.path.thicknesses[i] = 1;
          _obiRopeBlueprint.path.FlushEvents();
      }
    }


    private void OnDisable()
    {
      for (int i = 0; i < _obiRopeBlueprint.path.thicknesses.Count; i++)
      {
          _obiRopeBlueprint.path.thicknesses[i] = 1;
          _obiRopeBlueprint.path.FlushEvents();
      }
    }

In this script I achieved the desired visual, but there were some difficulties, namely -
1 - FPS sag, most likely because of the call FlushEvents() after changing thicknesses[i].
2 - when moving the object, to which the rope is tied, and pumping the rope - the anchor point shifts.

Maybe there is some easier or more obvious way to accomplish the same thing? For example, pick up the rendering of particles and change their thickness asynchronously there?  Or something else?

I am using obirope 6.4 now,
I want to change the head and tail bend angle of the rope, and keep the bend while moving.
At the beginning, I used static attachment and found that the effect was wrong. Later, when I added obicollider on the head and tail nodes and set dynamic, the effect was still wrong. Once moved, the head and tail did not keep the original bending, but random The shaking, the following is the effect picture after prohibition and movement. I want to keep the curved shape of the head and tail when it is still after moving.
This problem does not occur when I use the particlehandle component of 4.1 I hope to get a solution

Hello, I've copied the code in another Post to implement cutting Rope with collision.
It does cut the rope, but some rope does not get cut.
Turn out when I check the debug.log, it always cut the Rope02, but when I check in Inspector, the actual Rope is colliding with the cutter is Rope.
This implies my method of specify the Rope from solver.simplices and solver.particleToActor return wrong result.
I'll attached the project, please take a look.

I'm getting the Burst backend warning despite having all the dependencies installed.
Unity 2022.3.4f1 and Obi Fluid 6.5.4. The collection's package is supposed to be replacing jobs still I tried to manually add the old job package just to test and even then it still shows the warning.

Hey! The ropes have a clear example to create them in runtime without issues and I'm wondering if it's a good workthrough for softbodies. 

Thanks in advance

Hello, 

First of all think you for making a wonderful toolset with Obi Rope. 

I'm making a VR training app where the user needs to wield a tool that's connected to a cable, and the cable jack needs to be put into a slot. 
(Image something like holding an iPhone with a charging cable that you want to put into a USB slot)

When I have fairly large cables I don't have any problems, but when I make it a very small and thin cable (iphone charger) the cable doesn't attach to the tool properly, and it doesn't act good. Is there something I can do to remedy this?
