Walk-ons can be defined in the simplest of ways:
- Name (this is optional, but the one time you don't have one will be the time the player's ask for it)
- Purpose (what are they supposed to do in their scene)
- Motivation - something they want or are dealing with that might have nothing to do with 1 and 2 - this is the sort of thing that will inspire a player to interacted with a walk-on to the point where they become more important.
