How can I achieve this.  I am using the setting attached to automate my rotation of the object.  I have it set to rotate when Lens is initiated, but I want to make it pause, and then resume on tap events.  I was told I more than likely need to create a custom script for this.  Could someone help me figure this out?  my JS skills are rudimentary at best, and 'm really stumbling along through the code.  lol

  Hi Topher,

  You can achieve what you're describing with the following script.

  // ToggleTweenPlayback.js
  
  // tweenObject [SceneObject]: The SceneObject with the Tween Scripts
  //@input SceneObject tweenObject
  
  // tweenName [string]: The name of the tween to pause/resume on tap
  //@input string tweenName
  
  script.createEvent("TapEvent").bind(onTap);
  
  function onTap(e){
  
  if(global.tweenManager.isPaused(script.tweenObject, script.tweenName)){
  // Resume the tween if it is paused
  global.tweenManager.resumeTween(script.tweenObject, script.tweenName);
  }
  else if(global.tweenManager.isPlaying(script.tweenObject, script.tweenName)){
  // Pause the tween if it is playing 
  global.tweenManager.pauseTween(script.tweenObject, script.tweenName); 
  }
  }

  It will look like this when added to a Scene Object:

  

  Set Tween Object to the SceneObject that has a Tween script on it.

  Set Tween Name to the name of the tween you want to toggle.

  Let me know if you have any other questions!

  Best,

  Peter

  Hi Peter!  Thanks so much for taking the time to reply.  I put this script on my SceneObject "Jersey" and it changes the SceneObject from the green icon, to a script icon.  (not sure if this is supposed to).  Also, after that, I tried to put the Tween Object as the jersey mesh (blue icon), but the only Tween I have defined is TweensJersey, which is setting it to rotate... is that the Tween Name I should be setting?

  Just figured this out... after reading through the error log, I realized I needed to have the SceneObject as TweensJersey, not the actual mesh.  The tween is located inside the TweensJersey Scene Object. 

  Thanks!
