Study notes three

The camera follows the object

把脚本建在摄像机上，并在脚本中添加要跟随的对象，这个方法是用于添加力使物体
移动的方法

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

public class gen : MonoBehaviour
{
    
    
    public Vector3 dis;//存储距离（三维矢量）
    public GameObject ball;//ball存储要跟随的游戏对象
    // Start is called before the first frame update
    void Start()
    {
    
    
        dis = ball.transform.position - transform.position;//获取自身与小球的距离并赋值给dis
    }

    // Update is called once per frame
    void Update()
    {
    
    
        transform.position = ball.transform.position - dis;//自身的坐标等于小球的坐标减去开始的距离
    }
}

Two: Drag the camera directly to the object to be followed in the view. This method is used when the object is moving forward.
