Loop Video KUDAN AR

Question

我要把视频循环播放。视频结束后如何获取回调。我需要循环它，直到用户正在跟踪该视频

private func addVideoNode(bundleFileName: String, forTrackableImage imageTrackable: ARImageTrackable?){
    // Initialise video node
    let videoNode = ARVideoNode(bundledFile: bundleFileName)
    // Add video node to image trackable
    imageTrackable?.world.addChild(videoNode)
    // Video scale
    let scale = Float(imageTrackable?.width ?? 0) / Float(videoNode?.videoTexture.width ?? 0)
    videoNode?.scale(byUniform: scale)
    videoNode?.visible = false
    videoNode?.play()
}

Answer 1

在视频节点的ARPlayableTexture属性上注册为代理。

一旦视频播放完毕，代理就会得到一个回调：https://www.kudan.eu/docs-reference/iOSDocs/protocol_a_r_playable_texture_delegate_01-p.html。

Answer 2

必须像这样在videoNode上设置委托。

    videoNode?.videoTextureMaterial.texture.delegate = self

然后

extension ARViewController: ARPlayableTextureDelegate{
    func playableTextureDidFinish(_ texture: ARPlayableTexture!) {
        videoNode?.play()
    }
}
