Listing 15.9
Each exit sequence completes by setting the mode variable to ‘EXITED’; this is used by the
onClipEvent to trigger an ‘Into’ sequence. This in turn completes by setting the mode variable
to STATIONARY. Using this code you can move around any maze at will. Try creating a new
maze using the mazeMaker and then saving this as ‘maze.txt’ in the same folder as ‘maze.swf ’.
Running the ‘maze.swf ’ movie will load the new maze.
Suggestions for enhancement
The example is only the basis for a program; you can improve it by randomly blocking an exit,
or having a timer so that the user must move quickly. Maybe the map is usually hidden with
just a quick glance every now and then. Maybe you are being chased and have to avoid the cells
that contain baddies. You could work out a value for every cell as a distance to exit value. By
comparing this with the previous cell you could provide a ‘getting warmer’ or ‘getting colder’ bar
to help find the way out of the maze without a map. There are so many additions to the basic idea
that I leave it to the interested reader to add some excitement to the basic game.
