+``move_and_slide_with_snap``
+~~~~~~~~~~~~~~~~~~
+
+This method adds some additional functionality to ``move_and_slide()`` by adding
+the ``snap`` parameter. As long as this vector is in contact with the ground, the
+body will remain attached to the surface. Note that this means you must disable
+snapping when jumping, for example. You can do this either by setting ``snap``
+to ``Vector2(0, 0)`` or by using ``move_and_slide()`` instead.
