在Unity中播放和暂停播放增强现实(Vuforia)视频,可以通过以下步骤实现:
using UnityEngine;
using UnityEngine.Video;
using Vuforia;
public class ARVideoController : MonoBehaviour, ITrackableEventHandler
{
private TrackableBehaviour trackableBehaviour;
private VideoPlayer videoPlayer;
void Start()
{
trackableBehaviour = GetComponent<TrackableBehaviour>();
if (trackableBehaviour)
{
trackableBehaviour.RegisterTrackableEventHandler(this);
}
videoPlayer = GetComponent<VideoPlayer>();
}
public void OnTrackableStateChanged(TrackableBehaviour.Status previousStatus, TrackableBehaviour.Status newStatus)
{
if (newStatus == TrackableBehaviour.Status.DETECTED || newStatus == TrackableBehaviour.Status.TRACKED)
{
videoPlayer.Play();
}
else
{
videoPlayer.Pause();
}
}
}
完成以上步骤后,当Vuforia识别到目标时,视频将开始播放;当目标失去识别时,视频将暂停播放。这样就实现了在Unity中播放和暂停播放增强现实(Vuforia)视频的功能。
