title: Create infinite loop in Unity with delay
body: <p>I need to create a infinite loop in Unity without using the main thread? I saw some example, but it's not usefull:</p>
  
  <pre><code>while(true){
           var aa;
           debug.log("print.");
  } 
  </code></pre>
  
  <p>I want to add some delay like e.g. 2 seconds. If anybody knows the solution please help.</p>
