Hi,

You already asked this same question, and a complete example was provided. See:
http://obi.virtualmethodstudio.com/forum...t=callback

This is the sample code. Simply subscribe a function to the cloth's OnConstraintTorn callback. That's all there is to it:

Code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Obi;

[RequireComponent(typeof(ObiTearableCloth))]
public class ClothTornEvent : MonoBehaviour {

   ObiTearableCloth cloth;
   public GameObject thingToSpawn;

   void OnEnable () {
       cloth = GetComponent<ObiTearableCloth>();
       cloth.OnConstraintTorn += Cloth_OnConstraintTorn;
   }
   
   void OnDisable(){
       cloth.OnConstraintTorn -= Cloth_OnConstraintTorn;
   }
   
   void Cloth_OnConstraintTorn (object sender, ObiTearableCloth.ObiConstraintTornEventArgs e)
   {
       if (thingToSpawn != null)
           GameObject.Instantiate(thingToSpawn,cloth.Solver.positions[cloth.particleIndices[e.particleIndex]],Quaternion.identity);
   }
}

   }
}

How can I callback with that?

This is a regular C# event. Please read on how to use them.

I used code like this

Code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Obi;

[RequireComponent(typeof(ObiTearableCloth))]
public class ClothTornEvent : MonoBehaviour
{
   void Start()
   {
       this.GetComponent<ClothTornEvent>().enabled = false;
   }

   ObiTearableCloth cloth;
   public GameObject thingToSpawn;

   void OnEnable()
   {
       cloth = GetComponent<ObiTearableCloth>();
       cloth.OnConstraintTorn += Cloth_OnConstraintTorn;
       
   }

   void OnDisable()
   {
       cloth.OnConstraintTorn -= Cloth_OnConstraintTorn;
   }

   void Cloth_OnConstraintTorn(object sender, ObiTearableCloth.ObiConstraintTornEventArgs e)
   {
       Debug.Log("1");
       if (thingToSpawn != null)
       {
           GameObject.Instantiate(thingToSpawn, cloth.Solver.positions[cloth.particleIndices[e.particleIndex]], Quaternion.identity);
           Debug.Log("2");
       }
           
   }
}

However, I could not see "1" or "2" when the cloth is tore.  I need another thing? How can I get input from obi tearable cloth?

Maybe not disabling your component immediately in Start() would work

I wrote the code because of another problem, but it is okay now. Sorry.
