Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

Babel includes JSX processing.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

  <h1>Player Experience Equations</h1>
  <section>
    <div>
      <p>
        The purpose here is to show how an algorithm could prevent the problem of overpowered players in a VRMMO like Domino Finn's "Reboot" series.  
      </p>
      <p>
          Even if the player at the top gained an enormous amount of experience, they wouldn't level until the average of other players started to rise. 
        </p>
      <p>Conversely, a newbie would have a much easier time leveling.</p>
      <h2>Base Experience Equation</h2>
      <p>
        Let the base experience (b) equal 1000 * the level of the player (cpl).
      </p>
      <p>$$b = 1000 * cpl$$</p>
      <p>In the event that the character's level is the same as the average level of other characters, the base experience equation shall be used.</p>
      <h2>Base Equation for Highest Level Player</h2>
      <p>For the highest leveled player who is not equal to the average level, let experience equal the base experience (b) times the highest level player (h) divided by the average level of other players (avl) raised to the power of (h) minus the next highest leveled player (nh) + 1.</p>
    </div>

    <div class="equation">
      
      <p>$$exp = b({({h \over avl})^{(h-nh+1)}})$$</p>
    </div>
    <div class="equation">
      <h2>Base Equation for Other Players</h2>
      <p>For a player who is not the highest leveled player and is not at the same level as the average player, let experience (exp) equal the base experience (b) divided by the current player level (cpl) over the average player's level (avl)</p>
      <p>
        $$exp = {b({cpl \over avl})} $$
