你好，我正在尝试为我的角色创建一个AI，但它不工作。我希望它一看到我的角色就开枪，但它只是在场景中游荡，没有开枪，甚至我的debug.log也不起作用。

public Transform[] Targets;private int DestPoint = 0;private NavMeshAgent Agent;public Transform Player;public Rigidbody Bullet;public Transform Instantiator;void Start(){    Agent = GetComponent<NavMeshAgent> ();    Agent.autoBraking = false;}void Update(){    if (Vector3.Distance(transform.position, Player.position) < 30f)    {        Debug.Log ("Shoot");        transform.LookAt (Player);        Shoot ();    }    else if (Vector3.Distance(transform.position, Player.position) > 30f)    {        GotoNextPoint ();    }}void GotoNextPoint(){    Agent.destination = Targets [DestPoint].position;    DestPoint = (DestPoint + 1) % Targets.Length;}void Shoot(){    Rigidbody Clone = Instantiate (Bullet, Instantiator.position, Instantiator.rotation) as Rigidbody;    Clone.AddForce (Vector3.forward);}

回答：

距离永远不会小于30。在你的else语句中：

else if (Vector3.Distance(transform.position, Player.position) > 30f){    GotoNextPoint ();}

添加Debug.Log(Vector3.Distance(transform.position, Player.position));，这样你就可以看到你得到的值：

else if (Vector3.Distance(transform.position, Player.position) > 30f){    Debug.Log(Vector3.Distance(transform.position, Player.position));    GotoNextPoint ();}
