 One of the nice features in Godot's ``StateMachine`` implementation is the ability to travel. The graph can be instructed to go from the
 current state to another one, while visiting all the intermediate ones. This is done via the A\* algorithm.
-In the absence of any viable set of transitions starting at the current state and finishing at the destination state, the graph teleports
-to the destination state.
+If there is no path of transitions starting at the current state and finishing at the destination state, the graph teleports to the destination state.
 
 To use the travel ability, you should first retrieve the :ref:`AnimationNodeStateMachinePlayback <class_AnimationNodeStateMachinePlayback>`
 object from the ``AnimationTree`` node (it is exported as a property).
