VR游乐园学习—添加游乐项目视频

Posted 2022-09-10 dream-seeker-201907

（1）首先需要添加组件“VideoPlayer”

source为视频来源，URL为视频路径。

（2）通过脚本控制视频播放，在Quad上挂载

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Video;
using VRTK;
using System.IO;

public class GameItem : MonoBehaviour 

    public int Index;
    private VideoPlayer m_VideoPlayer;

    private void Awake()
    
        m_VideoPlayer = GetComponent<VideoPlayer>();
        GameObject.Find("ControllerRight").GetComponent<VRTK_ControllerEvents>().TouchpadReleased += GameItem_TouchpadReleased;
        GameObject.Find("ControllerLeft").GetComponent<VRTK_ControllerEvents>().TouchpadReleased += GameItem_TouchpadReleased;
    
    private void Update()
    
        if (Index == GameItemSelect._Instance.Index)
        
            GetComponent<MeshCollider>().enabled = true;
            GetComponent<MeshRenderer>().material.color = Color.white;
        else
        
            GetComponent<MeshCollider>().enabled = false;
            GetComponent<MeshRenderer>().material.color = Color.gray;
        
    
    /// <summary>
    /// 圆盘按钮抬起
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void GameItem_TouchpadReleased(object sender, ControllerInteractionEventArgs e)
    
        m_VideoPlayer.Pause();
    
    /// <summary>
    /// 设置视频名称
    /// </summary>
    /// <param name="videoName"></param>
    public void SetVideoName(string videoName)
    
        m_VideoPlayer.url = GetVideoPath(videoName);

    
    /// <summary>
    /// 获取视频路径
    /// </summary>
    /// <param name="videoName"></param>
    /// <returns></returns>
    private string GetVideoPath(string videoName)
    
        return Application.dataPath + "/StreamingAssets/" + videoName + ".mp4";

    
    private void OnTriggerEnter(Collider other)
    
        if (File.Exists(m_VideoPlayer.url) == false) return;
        m_VideoPlayer.Play();
    

    private void OnTriggerExit(Collider other)
    
        m_VideoPlayer.Pause();
