AR.js & Three.js: Pause Video When Marker Lost, Play When Found

This is an augmented reality experience created using AR.js and Three.js. The code displays a video when the camera detects a specific marker. When the camera loses the marker, the video pauses, and when the marker is found again, the video resumes playing. Here's the relevant code snippet that handles this functionality:

markerControls1.addEventListener('markerLost', function() {
  video.pause();
});

markerControls1.addEventListener('markerFound', function() {
  video.play();
});

This code uses event listeners for the 'markerLost' and 'markerFound' events. When the marker is lost, the video.pause() function is called to pause the video. Conversely, when the marker is found again, the video.play() function is called to resume playback.

This demonstrates a simple but effective way to control media playback based on the state of marker detection in AR.js. You can easily adapt this approach to other types of media or interactive elements within your AR experience.
