1.键盘移动控制：
using System.Collections;using System.Collections.Generic;using UnityEngine;public class PlayerMove2 : MonoBehaviour{// Start is called before the first frame updatepublic float speed = 3.5f;private CharacterController controller;void Start(){controller = transform.GetComponent<CharacterController>();}// Update is called once per framevoid Update(){var h = Input.GetAxis("Horizontal");var v = Input.GetAxis("Vertical");if(h!=0 || v!=0){Vector3 direction = new Vector3(h, 0, v);controller.Move(direction * speed * Time.deltaTime);transform.rotation = Quaternion.LookRotation(direction);}}}
2.镜头跟随：
using System.Collections;using System.Collections.Generic;using UnityEngine;public class CameraFollow : MonoBehaviour{// Start is called before the first frame updatepublic float speed = 3.5f;public Transform followtarget;public Vector3 offset;void Start(){offset = transform.position - followtarget.position;}// Update is called once per framevoid Update(){if(followtarget!=null){transform.position = Vector3.Lerp(transform.position, (followtarget.position + offset),speed*Time.deltaTime);}}}
也可以使用unity自带的一个package：cinemachine创建一个虚拟相机，设置相机参数和跟随目标即可
