跟着课程做的一个项目（VR游乐园）

课程地址

1. 摄像机跟随过山车的座位进行移动

用代码让摄像机跟随

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

public class Test : MonoBehaviour
{
    public Transform pos;
    public Transform rot;

    private void Awake()
    {
        UnityEngine.XR.InputTracking.disablePositionalTracking = false;
    }

    private void Update()
    {
        transform.position = pos.position + Vector3.up * 0.8f;
        transform.eulerAngles = new Vector3(rot.eulerAngles.x, rot.eulerAngles.y, rot.eulerAngles.z + 100f);
        transform.localScale = Vector3.one;
    }

}

2. 添加到终点倒计时

车身上的脚本

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

public class RollerCoaster : MonoBehaviour
{
    public AudioSource aud;
    private Animation ani;
    private float aniTime;
    private float timer;

    private bool isPlay = false;
    private bool isEnd = false;

    private void Awake()
    {
        ani = GetComponent<Animation>();
        aniTime = ani.clip.length;
    }

    private void Update()
    {
        aniTime -= Time.deltaTime;
        if(aniTime <= 10 && !isPlay)
        {
            aud.Play();
            isPlay = true;
        }
        if(aniTime <= 0 && !isEnd)
        {
            UnityEngine.SceneManagement.SceneManager.LoadScene("MainScene");
            isEnd = true;
        }
        if(aniTime <= 4)
        {
            timer += Time.deltaTime;
            if(timer >= 1)
            {
                timer = 0;
                CountDown.instance.OnCountDown();
            }
        }
    }

}

Canvas身上的脚本

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

public class CountDown : MonoBehaviour
{
    public static CountDown instance;
    private Text text;
    private int timer = 3;

    private void Awake()
    {
        instance = this;
        text = transform.Find("CountDown").GetComponent<Text>();
        gameObject.SetActive(false);
    }

    public void OnCountDown()
    {
        if(timer > 0)
        {
            gameObject.SetActive(true);
            text.text = timer.ToString();
            timer--;
        }
    }
