c# - Unity-“SetDestination”只能在已放置在NavMesh上的 Activity 代理上调用。 UnityEngine.NavMeshAgent:SetDestination(Vector3)

我现在正在使用Unity5。尝试setDestination时出现此错误。


  “ SetDestination”只能在已放置在NavMesh上的活动代理上调用。
      UnityEngine.NavMeshAgent：SetDestination（Vector3）
      CompleteProject.EnemyMovement：Update（）（位于Assets / _CompletedAssets / Scripts / Enemy / EnemyMovement.cs：30）


我的代码。

using UnityEngine;
using System.Collections;

namespace CompleteProject
{
    public class EnemyMovement : MonoBehaviour
    {
        Transform player;               // Reference to the player's position.
        PlayerHealth playerHealth;      // Reference to the player's health.
        EnemyHealth enemyHealth;        // Reference to this enemy's health.
        NavMeshAgent nav;               // Reference to the nav mesh agent.


        void Awake ()
        å{
            // Set up the references.
            player = GameObject.FindGameObjectWithTag ("Player").transform;
            playerHealth = player.GetComponent <PlayerHealth> ();
            enemyHealth = GetComponent <EnemyHealth> ();
            nav = GetComponent <NavMeshAgent> ();
        }


        void Update ()
        {
            // If the enemy and the player have health left...
            if(enemyHealth.currentHealth > 0 && playerHealth.currentHealth > 0)
            {
                // ... set the destination of the nav mesh agent to the player.
                nav.SetDestination (player.position);
            }
            // Otherwise...
            else
            {
                // ... disable the nav mesh agent.
                nav.enabled = false;
            }
        }
    }
}

您需要先向场景中添加一个导航网格，然后才能使用NavMeshAgent或与导航相关的任何其他功能。
