Unity 新导航寻路演示(2)

对于静态场景来说，只需要3步

1.为场景Ground添加网格表面组件并烘焙

2.为player添加导航代理

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;

public class PlayerMove : MonoBehaviour
{
    private NavMeshAgent agent;
    private Animator animator;
    // Start is called before the first frame update
    void Start()
    {
        agent = GetComponent<NavMeshAgent>();
        animator = GetComponent<Animator>();
    }

    // Update is called once per frame
    void Update()
    {
        if(Input.GetMouseButton(0))
            { 
            Ray ray =  Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hit;
            if(Physics.Raycast(ray,out hit,1000))
                {
                agent.SetDestination(hit.point);
            }
        }
        Vector3 v =agent.velocity;
        if(v.magnitude >0.1)
            {
            animator.SetBool("isRunning",true);
        }
        if(v.magnitude < 0.1)
            {
            animator.SetBool("isRunning", false);
        }
    }
}

3.编写代码
