Question

我需要循环播放视频。如何在视频结束时获得回调。我需要循环它直到用户跟踪该视频

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属性上注册为委托。

视频播放结束后，代理人会收到回电：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。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>NSHumanReadableCopyright</key> <!-- developer name key -->
    <string>Developer Name</string> <!-- developer name value -->
<!-- ... and further ... -->

然后

    videoNode?.videoTextureMaterial.texture.delegate = self

循环视频KUDAN AR
