how to stop navmesh agent when hit by object?

What do I need to add to stop my model using the navmesh agent when by and object.

Currently it gets hit goes ragdoll and then slides along the rest of the way!

This is the current script I am using what would I need to add in?

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

public class RagdollOnOff : MonoBehaviour
{
public CapsuleCollider mainCollider;
public GameObject ThisGuysRig;
public Animator ThisGuysAnimator;

void Start()
{
GetRagdollBits();
RagdollModeOff();

}
void Update()
{

}
private void OnCollisionEnter(Collision collision)
{
if(collision.gameObject.tag == "MyNewCollisionTag")
{
RagdollModeOn();
}
}

Collider[] ragDollColliders;
Rigidbody[] limbsRigidbodies;
void GetRagdollBits()
{
ragDollColliders = ThisGuysRig.GetComponentsInChildren<Collider>();
limbsRigidbodies = ThisGuysRig.GetComponentsInChildren<Rigidbody>();
}

void RagdollModeOn()
{
ThisGuysAnimator.enabled = false;

foreach (Collider col in ragDollColliders)
{
col.enabled = true;
}

foreach (Rigidbody rigid in limbsRigidbodies)
{
rigid.isKinematic = false;
}

mainCollider.enabled = false;
GetComponent<Rigidbody>().isKinematic = true;
}

void RagdollModeOff()
{
foreach(Collider col in ragDollColliders)
{
col.enabled = false;
}

foreach (Rigidbody rigid in limbsRigidbodies)
{
rigid.isKinematic = true;
}

ThisGuysAnimator.enabled = true;
mainCollider.enabled = true;
GetComponent<Rigidbody>().isKinematic = false;
}

}

You can disable the navmesh agent component and that will stop them. And then reenabling should get them back on track

 

(tbf, I'd still consider this scripting as it's not necessarily about the navigation itself, rather scripting around it and that forum isn't nearly as viewed as scripting)
