canUndo
It’s generally possible to undo a travel command.
direction
The direction the actor wants to travel in. This is placed here by the execCycle method and takes the form of A Direction object, e.g. northDir.
predefinedDirection
Does this TravelAction already define a set direction on its direction property (so we don’t need to look to what direction object the command refers)?
Methods
doTravel ( )
Carry out travel in direction. For this purpose we first have to define what the corresponding direction property of the actor’s current location refers to. If it’s nil, no travel is possible, and we simply display a refusal message. If it’s an object we execute its travelVia() method for the current actor. If it’s a double-quoted string or a method we execute it and make a note of where the actor ends up, if the actor is the player character. If it’s a single-quoted string we display it.
Note that we only display the various messages announcing failure of travel if the actor is the player character. We presumably don’t want to see these messages as the result of NPCs trying to move around the map.
execAction (cmd)OVERRIDDEN
Execute the travel command, first carrying out any implicit actions needed to facilitate travel
execCycle (cmd)OVERRIDDEN
Use the inherited handling but first make a note of the direction the actor wants to travel in.
