   * <strong>Swing across</strong> one
   * {@link adventurejs.Tangible|Tangible}
   * {@link adventurejs.Asset|Asset} on another.
   * Requires that the direct object has its
   * <a class="code" href="/doc/adventurejs.Tangible.html#property_can_swing_across">can.swing_across</a>
   * property set to true, and the indirect object has its
   * <a class="code" href="/doc/adventurejs.Tangible.html#property_can_swing_on">can_swing.on</a>
   * property set to true.
   * The verb is intended for statements like

   * but no special logic is provided.
   * Authors wanting to make use of it may need to use a method such
