Section: Specifying the probability that a Patroller will move
We can specify how likely it is that a Patroller will move on any turn by setting the Drive of the Patroller to a value from 0 to 100. 100 means that the Patroller will always move (this is the default value) if it is possible to do so. For example, to set a 40% chance of the Patroller moving:
The Drunken Lord is a Patroller in the Bar. The Drunken Lord is Aimless.
The Drive of the Drunken Lord is 40.
