前言

演示

提示：以下是本篇文章正文内容，下面案例可供参考

一、准备一些Object

示例：准备Player，Plane，Obstacle

二、代码示例

1.Player脚本

代码如下（示例）：

/****************************************************
    文件：Player.cs
	作者：HKZ
    邮箱: [e-mail]
    日期：2022/1/9 12:2:45
	功能：Player输入（把此脚本挂在Player物体上）
*****************************************************/

using UnityEngine;

namespace HKZ

    [RequireComponent(typeof(PlayerController))]
    public class Player : MonoBehaviour
    
        [SerializeField]
        private float moveSpeed = 5.0f;

        private Camera viewCamera;
        private PlayerController playerController;

        private void Start()
        
            playerController = GetComponent<PlayerController>();
            viewCamera = Camera.main;
        

        private void Update()
        
            //Movement Input
            Vector3 moveInput = new Vector3(Input.GetAxisRaw("Horizontal"), 0f, Input.GetAxisRaw("Vertical"));
            Vector3 moveVelocity = moveInput.normalized * moveSpeed;
            playerController.Move(moveVelocity);

            //Look Input
            Ray ray = viewCamera.ScreenPointToRay(Input.mousePosition);
            Plane groundPlane = new Plane(Vector3.up, Vector3.zero);
            float rayDistance;
            if (groundPlane.Raycast(ray, out rayDistance))
            
                Vector3 point = ray.GetPoint(rayDistance);
                //Debug.DrawLine(ray.origin, point, Color.red);
                playerController.LockAt(point);
            
        
    

2.PlayerController脚本

代码如下（示例）：

/****************************************************
    文件：PlayerController.cs
	作者：HKZ
    邮箱: [e-mail]
    日期：2022/1/9 12:2:59
	功能：PlayerController方法
*****************************************************/

using UnityEngine;

namespace HKZ

    [RequireComponent(typeof(Rigidbody))]
    public class PlayerController : MonoBehaviour
    
        private Vector3 velocity;

        private new Rigidbody rigidbody;

        private void Start()
        
            rigidbody = GetComponent<Rigidbody>();
        
        private void FixedUpdate()
        
            rigidbody.MovePosition(rigidbody.position + velocity * Time.fixedDeltaTime);
        

        public void Move(Vector3 moveVelocity)
        
            velocity = moveVelocity;
        

        public void LockAt(Vector3 point)
        
            Vector3 heightCorrectedPoint = new Vector3(point.x, transform.position.y, point.z);
            transform.LookAt(heightCorrectedPoint);
        
    

3.Hierarchy面板
