title: ARCore: execute each frame instead of when touching the screen (Unity)
body: <p>I am working in a project which needs to execute a function every frame, but without clicking the screen. I dont know why putting the code in the Update function doesnt work (it needs all time and anyway, to touch the screen to execute the code). I put here the part of the code I want to play every frame:</p>
  
  <pre><code>     anchor.transform.position = Vector3.zero; 
       hotPoint.transform.position = Vector3.zero;
       _androidPosVector3ZeroText.text = anchor.transform.position.ToString(); 
       _camPosText.text = FirstPersonCamera.transform.position.ToString();
  </code></pre>
  
  <p>I am going to explain how it works: I have placed the android icon and also its anchor in the 0, 0, 0 world position. I do that because I always want to know where is the center of my world in the app. And finally, I want to know every frame which is the camera position relative to that center. I show each value in a text. And this code is in the Update function, and I dont know why I have to touch the screen to execute it, if it is NOT in any if or something...</p>
  
  <p>Thank you so much in advance!</p>
