Check if whole rope is inside a trigger

[Spectra_7]

Hello. First of all, great asset.

The rope falls down from top.
I want to trigger an event when the whole rope is inside this box trigger. Is this possible?


Thanks.

Sure,

Just subscribe to the solver's OnCollision event. If all particles belonging to the rope have a contact with the trigger, you call whatever function you need. See:

Thanks for the reply.

Like you said, I got it work the way I wanted. I am dropping the script here in case someone finds it useful:

Code:

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

public class RopeTriggerCheck : MonoBehaviour
{
    public ObiSolver solver;
    public ObiActor ropeActor;
    public Collider triggerCollider;
    public float currentParticlesCount = 0;
    public float totalParticlesCount;
    public bool isEventTriggered;

    public List<int> particlesEnteredList = new List<int>();

    private ObiRopeBlueprint ropeBlueprint;
   
    private void Start()
    {
        if(ropeActor == null)
            ropeActor = solver.actors[0];

        ropeBlueprint = (ObiRopeBlueprint)ropeActor.blueprint;
        totalParticlesCount = ropeBlueprint.activeParticleCount;
        isEventTriggered = false;
    }

    private void OnEnable()
    {
        solver.OnCollision += Solver_OnCollision;
    }

    private void OnDisable()
    {
        solver.OnCollision -= Solver_OnCollision;
    }

    void Solver_OnCollision(object sender, Obi.ObiSolver.ObiCollisionEventArgs e)
    {
        //print(e.contacts.Count);       

        for (int i = 0; i < e.contacts.Count; ++i)
        {
            if (e.contacts.Data[i].distance < 0.01f)
            {
                Component collider;
                if (ObiCollider.idToCollider.TryGetValue(e.contacts.Data[i].other, out collider))
                {
                    if (collider == triggerCollider)
                    {
                        if(!particlesEnteredList.Contains(e.contacts.Data[i].particle))
                            particlesEnteredList.Add(e.contacts.Data[i].particle);

                        currentParticlesCount = particlesEnteredList.Count;

                        if(currentParticlesCount >= totalParticlesCount && !isEventTriggered)
                        {
                            //Trigger an Event you like
                            isEventTriggered = true;                           
                           
                        }
                    }
                }
            }
        }
    }
}

Thanks a lot.
