Unity如何實現警車抓捕玩家車輛，並避免使用尋路代理後，直接撞飛玩家

代碼如下：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;

public class AIEnemy : MonoBehaviour
{

private NavMeshAgent nav;

public GameObject targetPos;

public bool isNavGuide = true;

public float catchDis = 20.0f;

public int enemySpeed = 15;

public AIVehicle aIVehicle;

private Rigidbody rig;

void Start()
{
    nav = this.transform.GetComponent<NavMeshAgent>();
    targetPos = GameObject.FindGameObjectWithTag("Player");
    aIVehicle = targetPos.GetComponent<AIVehicle>();

}


void Update()
{
     if (isNavGuide != false && aIVehicle.currentLap != 1)
     {
         CalEnemyToPlayer();
     }
}

public void CalEnemyToPlayer()
{
    try
    {
        nav.enabled = true;
        nav.speed = enemySpeed;
        transform.LookAt(targetPos.transform);
        nav.SetDestination(targetPos.transform.position);
        float dis = Vector3.Distance(this.transform.position, targetPos.transform.position);
        //float dis = nav.remainingDistance;

        if (dis < catchDis+10)
        {
            aIVehicle.isGameOver = true;
           
            //nav.acceleration = -(nav.speed/5.0f);
            isNavGuide = false;
            StartCoroutine(StopNav());
            nav.speed = Mathf.MoveTowards(nav.speed, 0, 1.0f);

          

            Debug.Log("Game Over...");
        }
    }
    catch (System.Exception e)
    {
        Debug.Log("The Err is:" + e);
    }

}

IEnumerator StopNav()
{
    yield return new WaitForSeconds(1.1f);
    nav.isStopped = true;
    nav.enabled = false;
    Debug.Log("Stop Nav...");
}

}
