 Here, we only normalize the vector if the direction has a length greater than
 zero, which means the player is pressing a direction key.
 
-In this case, we also get the ``Pivot`` node and call its ``look_at()`` method.
-This method takes a position in space to look at in global coordinates and the
-up direction. In this case, we can use the ``Vector3.UP`` constant.
-
-.. note::
-
-    A node's local coordinates, like ``position``, are relative to their
-    parent. Global coordinates, like ``global_position`` are relative to the world's main axes you can see
-    in the viewport instead.
-
-In 3D, the property that contains a node's position is ``position``. By
-adding the ``direction`` to it, we get a position to look at that's one meter
-away from the ``Player``.
+We compute the direction the ``$Pivot`` is looking by creating a :ref:`Basis <class_Basis>`
+that looks in the ``direction`` direction.
 
 Then, we update the velocity. We have to calculate the ground velocity and the
 fall speed separately. Be sure to go back one tab so the lines are inside the
