Section E(i) - Exploring the labyrinth

Definition: A labyrinth room is acceptable if it is unplaced and its minimum level <= the current maze level.

Before going a direction (called this way) to Terra Incognita:

if the location is unplaced or this way is not vectorial, say "Oops! You should only reach terra incognita from a placed room via a vectorial direction."; [1]

if Terra Incognita is closed, say "The way is barred by some enchantment of the never-children." instead;

let possibles be the number of acceptable labyrinth rooms;

if possibles is 0:

retrieve inaccessible labyrinth rooms;

let possibles be the number of acceptable labyrinth rooms;

if possibles is 0:[2]

now Terra Incognita is closed;

say "In your mind, you hear the scornful laughter of the never-children. 'Magic-uther has run out of labyrinth!' And certainly the way is blocked." instead;

if possibles > 0:

let the new room be a random acceptable labyrinth room;

let the current position be the grid position of the location;

let the new position be the vector sum of the current position and the vector of this way;

position the new room at the new position;

otherwise:

change this way exit of the location to Solid Rock;

try going this way instead.

After going up to a labyrinth room from a non-ascending labyrinth room: say "You take the well-remembered secret staircase up."; continue the action.

After going down to a labyrinth room from a non-descending labyrinth room: say "You take the well-remembered secret staircase down."; continue the action.

Instead of going to Solid Rock:

say "After a few strides, the way gives out into ";

if the current maze level is 1, say "dense, impenetrable undergrowth";

otherwise say "solid rock";

say ". You step back again."

Notes

[1]. This never happens, of course: it was put in to test the game.

[2]. I.e., if even retrieving unvisited rooms didn't help: now the maze really is exhausted.
