Unity3D敌人AI脚本帮助（C＃）？

Question

我是意大利人，这是我编程的第一周团结一致，我试图为跟随并攻击玩家的僵尸创建脚本。我上传了脚本，并添加了一些注释以澄清代码。我的债务是：-为什么僵尸可以通过玩家？-这是创建此脚本的最佳简单方法吗？这是navmesh的正确用法吗？-如何在navmesh中使用物理？一些代码行是我在网上找到的示例（随机移动功能），我需要一些帮助和技巧。

public class simpleNav : MonoBehaviour
{
  [SerializeField] public Animator myAnimationController;
  public GameObject target;
  NavMeshAgent agent;

  public int vita_z;
  public bool morto;

private float timer;
public float wanderRadius;
public float wanderTimer;


// Start is called before the first frame update
void Start()
{

    agent = GetComponent<NavMeshAgent>();

    myAnimationController.SetBool("condizione", false);   //this is the start animation, the zombie is in idle
    morto = false;
}

// Update is called once per frame
void Update()
{
    if (morto != true) //if zombie isn't die
    {
        agent.isStopped = false;
        float dist = Vector3.Distance(transform.position, target.transform.position);
        myAnimationController.SetBool("condizione", true); //start walk animation


        if (dist <= 20)
        {  
            agent.SetDestination(target.transform.position);
            agent.speed = 5;
            myAnimationController.SetBool("corre", true); //start run animation
        }



        else
        {
            myAnimationController.SetBool("corre", false); //stop run animation, walk animation starts
            agent.speed = 1.3F;
            timer += Time.deltaTime;

            if (timer >= wanderTimer)
            {
                Vector3 newPos = RandomNavSphere(transform.position, wanderRadius, -1); //function from internet to generate random movement
                agent.SetDestination(newPos);

                timer = 0;
            }
        }
    }

   else agent.isStopped = true;
}


void OnTriggerEnter(Collider other)
{
    if (other.gameObject.tag == "bullet")
    {
        vita_z -= 10; //if bullet enter, the life of the zombie will be decremented

        if (vita_z <= 0 && morto != true) //when life <= zero, play the die animation
        {
            punt_e_vita.currentScore += 10; //player's score increment
            morto = true; //die = true
            myAnimationController.SetBool("sparato", true); //die animation
        }
    }

    else if (other.gameObject.tag == "player")
    {

        if (morto != true)
        {
            punt_e_vita.vita -= 5; //decrement the life of the player
        }
    }
}

private void OnTriggerStay(Collider other)
{
    if(other.gameObject.tag == "player")
    {

        myAnimationController.SetBool("attacca", true); //this is attack animation if the object in collider is the palyer

    }
}
void OnTriggerExit(Collider other)
{
    if (other.gameObject.tag == "player")
    {
        myAnimationController.SetBool("attacca", false);//stop attack
    }

    myAnimationController.SetBool("sparato", false);

}


public static Vector3 RandomNavSphere(Vector3 origin, float dist, int layermask) //this is the random movement function
{
    Vector3 randDirection = Random.insideUnitSphere * dist;

    randDirection += origin;

    NavMeshHit navHit;

    NavMesh.SamplePosition(randDirection, out navHit, dist, layermask);

    return navHit.position;
}
}

如果您想让敌人避免与玩家碰撞，或希望导航避免某些对象对其使用障碍组件并将其更改为动态，则您的导航网格将在运行时更新，并且代理将避免与这些对象发生碰撞。

至于脚本，这只是您可以通过事物的工作方式来实现或学习的基本功能，但是脚本大多基于您要实现的目标，如果您只想跟随并被玩家击落，那就可以了。
