Help About "Edit Particles-> Fix Translation" when creating cloth before execution.

[josemendez]

Creating a Cloth object with Obi before running was a success.
However, the cloth generated at runtime seems to mean that it doesn't move with the red particles as shown. (Attachment 1)

How should I write a script to fix this?
The method I tried is the following script,

Code:

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

[RequireComponent(typeof(MeshFilter))]
// [RequireComponent(typeof(SkinnedMeshRenderer))]

public class genCloth : MonoBehaviour
{

   public Mesh mesh;
   public SphereCollider virtualHand;
   public float Damping = 0;
   public float Stretching = 0;
   public float Bending = 0;
   public int resolution;
   public Vector3 Accelerration;
   private Cloth component;

   public ObiSolver solver;
public ObiMeshTopology topology;
   public void setUpObi() {
       if(mesh == null || topology == null){
           Debug.LogError("Either the mesh or the topology are null. You must provide a mesh and an empty topology asset in order to generate cloth.");
       }

       ObiCloth cloth = GetComponent<ObiCloth>();

       var filter = GetComponent<MeshFilter>();
       filter.sharedMesh = mesh;
       var skin = GetComponent<SkinnedMeshRenderer>();
       skin.sharedMesh = mesh;

       topology.InputMesh = mesh;
       topology.Generate();

       cloth.Solver = solver;
       cloth.SharedTopology = topology;
       
       cloth.enabled = true;
       
       StartCoroutine(cloth.GeneratePhysicRepresentationForMesh());

       cloth.AddToSolver(null);

       for(int i = 0; i < mesh.vertices.Length; i++){
           cloth.invMasses[i] = 1.0f / (Mathf.Max(1,0.00001f) * cloth.areaContribution[i]);
           cloth.velocities[i] = Vector3.zero;
       }
       cloth.PushDataToSolver(ParticleData.INV_MASSES | ParticleData.VELOCITIES);


   }

}

Before the initialization coroutine was finished, the value was rewritten, and only the last particle appeared blue, which was meaningless. (Attachment 2)


How can I solve it?

Simply wait for the GeneratePhysicRepresentationForMesh() coroutine to finish before changing particle masses. You're immediately continuing after spawning the coroutine and changing masses/velocities, so the coroutine (whose execution is interleaved with the code after the StartCoroutine call) is overwriting your values.
