Unity实现飞行相机、路径相机、晃动相机、手机触摸旋转模型、鼠标点击模型播放视频

一、飞行相机代码展示：

UpDown需要在如下添加A、D键

using System;
using UnityEngine;

public class FlightCamera : MonoBehaviour
{
    public Transform flyCamera;
    public float translationSpeed = 5f;
    public float runTranslationSpeed = 10f;
    public float rotationSpeed = 100f;
    
    public float rotationMultiplier = 2f; // 控制旋转速度的倍数
    // public float minRotationAngle = -80f; // 最小旋转角度
    // public float maxRotationAngle = 80f; // 最大旋转角度

    private Vector3 posInit;
    private Vector3 rotInit;
    private Vector3 flyCameraPosInit;
    void Awake()
    {
        posInit = this.transform.position;
        rotInit = this.transform.eulerAngles;
        flyCameraPosInit = flyCamera.transform.localEulerAngles;
    }
    
    public void StartFlyCamera()
    {
        this.transform.position = posInit;
        this.transform.eulerAngles = rotInit;
        flyCamera.transform.localEulerAngles = flyCameraPosInit;
    }
    
    void Update()
    {
        var _translationSpeed = Input.GetKey(KeyCode.LeftShift) ? runTranslationSpeed : translationSpeed;
        
        // 前后移动
        float verticalInput = Input.GetAxis("Vertical");
        transform.Translate(Vector3.forward * verticalInput * _translationSpeed * Time.deltaTime);

        // 上下平移
        float upDownInput = Input.GetAxis("UpDown");
        transform.Translate(Vector3.up * upDownInput * _translationSpeed * Time.deltaTime);

        // 左右旋转
        float horizontalInput = Input.GetAxis("Horizontal");
        transform.Rotate(Vector3.up, horizontalInput * rotationSpeed * Time.deltaTime);
        
        
        // 鼠标右键按下并上下滑动控制 X 轴旋转
        if (Input.GetMouseButton(1))
        {
            float mouseY = Input.GetAxis("Mouse Y") * rotationSpeed * rotationMultiplier * Time.
