Hi.

I need particles to be killed once they are below a given position.y
In my situation, the particles should live as long as they don't fall below some position. Once enough are killed, new ones would be emitted.

Here's my code for now but something is not right. It finds the particle pos but the kill part does not seem to work because my active particle number (in the emitter inspector)  stays the same when running. If possible, I would like also something less demanding than having to regularly loop through the array to do the pos check. 

Hi All,
First of all - I have to say that i really like this product, simulations are very realistic, fast, configurable - well done! (documentation could be improved

using unity 2018.2.1f1 
using Obi 4.0.2

My real scene is a little complex with many moving solvers/emitters, so I built a simple demo scene to demonstrate the problem.
In general: fluid stream collide with a sphere, collided particles are being killed, and for every killed particle a new particle is emitted from a local emitter on the sphere

The demo scene includes the following GameObjects/Components:
1)MainSolver - Empty with a solver (global space) and a script MainCollisionDetection(described bellow)
(solver constraints copied from Obi sample scene "FluidViscosity")
2)MainEmitter - Empty with an ObiEmitter (that uses MainSolver as its solver) and particle renderer
  emitter properties: speed: 5, emitter material: Honey, collision material :very sticky
3)Sphere - unity sphere with ObiCollider ,RB, and ObiRB
  a)SphereSolver - child of Sphere - Empty with a solver (local space)
    (solver constraints copied from Obi sample scene "FluidViscosity")
    1. SphereEmitter - child of SphereSolver - empty with an ObiEmitter (that uses SphereSolver as its solver) and particle renderer
       emitter properties: speed: controlled by script SphereEmitionControl (described bellow), emitter material: Honey, collision material :very sticky 

4)MainCollisionDetection script detects collisions (on MainSolver), kills the hitting particle, and adds the particle collision data to a queue in the SphereEmitionControl script

I'm using the linux version of unity and it keeps having problems finding liboni.  The .dll and .so are in obi->plugins->x86_64

[Solved]
Seems unity is expecting to find this lib in /home/$user/Unity/Hub/Editor/2018.3.5f1/Editor/Data/Mono/lib/. Once liboni.so was placed in there it stopped complaining and obi now works.  You'll also have to remove obi/plugin/x86_64/liboni.so or it bitches there's two versions of the lib.  Not sure yet if this effects building the game or not.

Plopping this thread so future users can find it.

Ao I recently got obi-rope and so far like what I see but I'm not sure how to use it for what I want. One vehicle is going to have a winch and i need to have it so the player can pull the cable out via hook and carry it with them with the cable extending as they pull out and not auto feed out. My first plan was to physically wrap the cable around the drum like real life and set motor to free spool so when the player tugs the rope it unspools but that seems intensive unless obi rope can handle that no problem. 

My second solution was to attach the rope to the end of the winch body and have it extend when it's being tugged on and the player has the hook in their hand.

Any ideas on the matter? The first option would be ideal as maximum realism is my goal if there is a good way to do that without high cpu useage.

I need to do this but I don't Know how to config this

Hello.

I want to make if statement when the cloth is tore. How can I do that?

Hi, 

1. I'm wondering if the Obi products will be updated (with bug fixes) on the Unity Asset store soon. Several bug fixes are floating around on the forums that I constantly have to hunt down and add when creating new projects using Obi Assets. 


2. Would you create a video on how to control a softbody ball with a rigidbody - that actually collides with the floor. 
I think I'm doing something wrong or missing a step. Every time I attempt it, the ball simply falls thru the floor. 

Thanks

Hi,

Followed the quick setup guide.  Brought in an Obi Solver into the scene, set a child object with a Skin Mesh Renderer up with the Obi Cloth Component (along with it's additional components all left as default), then clicked initialize.

After hitting play, I get slammed with this error message:

Assertion failed on expression: 'offset + size <= bufLen'

Over and over again.  Everything in the setup was not really modified a part from bringing in the appropriate data for setting up the Game Object.  Has anyone had to deal with this issue and/or know how to deal with it?

I've brought just the Model into a scene and set it up, got the error message when it's simulating.  In our main scene, as soon as the character is to animate through a Timeline, the character freezes up and the child object on the character isn't getting affected by the Obi Cloth.

Thanks,
Cole

Hello.
I try to add vector to obi cloth. I have a error:Cannot implicitly convert type 'UnityEngine.Vector3' to 'float', but the direction of coding is not problem?

using UnityEngine;
using System.Collections;
using Obi;

[RequireComponent(typeof(ObiActor))]
public class DistanceAnchor : MonoBehaviour
{

    ObiActor actor;
    public ObiSolver solver;
    


    void Awake()
    {
        actor = GetComponent<ObiActor>();

    }

    void Update()
    {
        ObiSolver solver = actor.Solver;

        float invMassPerParticle = 0.01f;
        for (int i = 0; i < actor.invMasses.Length; ++i)
        {
            int indexInSolver = actor.particleIndices[i];
            actor.invMasses[i] = solver.invMasses[indexInSolver];
            actor.invMasses[i] = new Vector3(0.0f, 0.05f, 0.0f);
            
        }
    }
}

Hi there,

yesterday I purchased your Softbody unitypackage. I am trying to stick two objects together (like in your example on the website with the cloth). 

I created a sticky material and applied it to two spheres, which have soft bodies on them. But the don't stick to each other.

The obi solver has Collision and Particle Collision checked true. I also tried adding collideres to the spheres, but that changes nothing.

Am I missing something? Any help will be appreciated.
