/** @file
|
|
This script is used with the Maze spell's maze
|
|
area movement control triggers. It determines
|
|
the directions the PC can go and randomly
|
|
selects one. If possible, it avoids moving
|
|
to the same direction the PC came from.
|
|
|
|
The directions possible are stored as bit flags
|
|
on a local integer called "directions" on the
|
|
trigger.
|
|
The non-preferred direction is stored as
|
|
local integer "PRC_Maze_Direction" on the creature.
