Unity自学笔记——Day01_实现WASD键盘控制移动人物和镜头跟随

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 update
    public float speed = 3.5f;
    private CharacterController controller;
    void Start()
    {
    
    
        controller = transform.GetComponent<CharacterController>();
    }

    // Update is called once per frame
    void 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 update
    public float speed = 3.5f;
    public Transform followtarget;
    public Vector3 offset;
    void Start()
    {
    
    
        offset = transform.position - followtarget.position;
    }

    // Update is called once per frame
    void 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
