1.首先添加场景模型
2.为场景模型（寻路路径）添加NavMesh渲染，操作：Windows->Navigation->勾选Navigation Static选项->不勾选Generate选项->Navigation Area选为Walk able->Back栏调整Agent Radius参数->Bake按钮完成寻路渲染
3.为要移动物体添加Nav Mesh Agent组件
4.为要移动物体添加脚本
using UnityEngine;
using UnityEngine.UI;
using System.Collections; public class bassTest : MonoBehaviour {
//移动控制
private NavMeshAgent Car;
//货物模型，直接拖拉
public GameObject Goods;
//目标点（若要程序调用，请设为Static）
public Vector3 target;
void Awake () {
Car = gameObject.GetComponent<NavMeshAgent> (); target = transform.position; }
void Update () {
Car.SetDestination (target);
}
}
