   * <p>
   * <strong>ClimbableVine</strong> is a subclass of
   * {@link adventurejs.Climbable|Climbable}, a hanging vine
   * that a player can climb on/to/from,
   * swing on/to/from, jump to/from. What makes ClimableVine
   * special is its combination of its position.y and its height
   * properties. Here is an example of a
   * hanging vine that doesn't reach the ground, making a puzzle
   * of how to reach it.
   * </p>
   * <pre class="display"><code class="language-javascript">MyGame.createAsset({
   *   class: "ClimbableVine",
   *   name: "vine",
   *   place: { in: "Cave" },
   *   descriptions: { look: "It's a vine. ", },
   *   position: { x:0, y:3, z:0 },

   *   things_player_can_reach_from_this: [ "tree", "stalactite" ],
   * });
   * </code></pre>
   * <p>
   * See that the vine's position.y is 3 units high, presumably
   * at ceiling height, and that its height is -2, meaning that
   * it hangs down 2 units from the ceiling and reaches 1 unit
   * above the ground, just out of reach of the player.
