title: Unity C# Cycling some texts without repeating them
body: <p>I've a line in the bottom part of the main screen of the game, that every time the scene is loaded, it shows a different tip (how to play, how to change music...).</p>
  
  <p>The question is that I'm using Random.Range for that but, honestly, I'll prefer a way where all tips are showed, one by one in a random way, but without repeating any of them.</p>
  
  <p>My code is as follows:</p>
  
  <pre><code>int randNum;
  void Start () {
      randNum = Random.Range(0,5);
  }
  
  void Update () {
  
      switch (randNum)
      {
          case 0:
         // blah, blah, blah...
          case 1...
  </code></pre>
  
  <p>How can I achieve what I want?</p>
  
  <p>Thans for yout timeeee :)</p>
