How to trigger an action by colliding with a certain object at a certain force

[dcybroz]

Hello,
I want to trigger a shatter script I made for this glass cup (see image)

The problem I have been having is that I have not found any force detection or unit in the unity physics engine. Here is the code I am currently using:

using UnityEngine;
public class Destroyobj : MonoBehaviour
{
    public GameObject destroyedVersion;
    private void OnCollisionEnter(Collision collision)
    {
        float collisionForce = collision.impulse.magnitude / Time.fixedDeltaTime;

        if (collisionForce < 100.0F)
        {
            void OnCollisionEnter()
            {
                Instantiate(destroyedVersion, transform.position, transform.rotation);
                Destroy(this.gameObject);
            }

        }
    }
}

It also shatters if it doesn’t move but if I drop it stays together
Help would be appreciated
