Hunt the Wumpus
You are encouraged to solve this task according to the task description, using any language you may know.
Create a simple implementation of the classic textual game Hunt The Wumpus.
The rules are:
The game is set in a cave that consists of a 20 room labyrinth. Each room is connected to 3 other rooms (the cave is modeled after the vertices of a dodecahedron). The objective of the player is to find and kill the horrendous beast Wumpus that lurks in the cave.
The player has 5 arrows. If they run out of arrows before killing the Wumpus, the player loses the game.
In the cave there are:
- One Wumpus
- Two giant bats
- Two bottomless pits
If the player enters a room with the Wumpus, he is eaten by it and the game is lost.
If the player enters a room with a bottomless pit, he falls into it and the game is lost.
If the player enters a room with a giant bat, the bat takes him and transports him into a random empty room.
Each turn the player can either walk into an adjacent room or shoot into an adjacent room.
Whenever the player enters a room, he "senses" what happens in adjacent rooms. The messages are:
- Nearby Wumpus: "You smell something terrible nearby."
- Nearby bat: "You hear a rustling."
- Nearby pit: "You feel a cold wind blowing from a nearby cavern."
When the player shoots, he wins the game if he is shooting in the room with the Wumpus. If he shoots into another room, the Wumpus has a 75% of chance of waking up and moving into an adjacent room: if this is the room with the player, he eats him up and the game is lost.
Ada
This version is implemented using an Ada package and a very short main procedure. The Ada packages are divided into package specifications and package bodies. The package specification contains the API for the package. The package body contains the implementation of the package functionality.

Go
I've tried to stick as closely as possible to the task description but, as some points are unclear, I've had to make the following assumptions:
1. The bats and the pits are in separate rooms but the Wumpus can be in any room whether there's another hazard in it or not.
2. The game starts with the player in room 1 which initially contains no hazards.
3. If a bat transports the player to a random empty room, it returns to its original room.
4. If the Wumpus wakes up and moves to an 'adjacent' room, it means a room adjacent to the Wumpus not necessarily the player. <lang go>package main

WELCOME TO 'HUNT THE WUMPUS'
THE WUMPUS LIVES IN A CAVE OF 20 ROOMS. EACH ROOM
HAS 3 TUNNELS LEADING TO OTHER ROOMS. (LOOK AT A
DODECAHEDRON TO SEE HOW THIS WORKS-IF YOU DON'T KNOW
WHAT A DODECAHEDRON IS, ASK SOMEONE)
HAZARDS:
BOTTOMLESS PITS - TWO ROOMS HAVE BOTTOMLESS PITS IN THEM
IF YOU GO THERE, YOU FALL INTO THE PIT (& LOSE!)
SUPER BATS - TWO OTHER ROOMS HAVE SUPER BATS. IF YOU
GO THERE, A BAT GRABS YOU AND TAKES YOU TO SOME OTHER
ROOM AT RANDOM. (WHICH MIGHT BE TROUBLESOME)
WUMPUS:
THE WUMPUS IS NOT BOTHERED BY THE HAZARDS (HE HAS SUCKER
FEET AND IS TOO BIG FOR A BAT TO LIFT). USUALLY
HE IS ASLEEP. TWO THINGS WAKE HIM UP: YOUR ENTERING
HIS ROOM OR YOUR SHOOTING AN ARROW.
IF THE WUMPUS WAKES, HE MOVES (P=.75) ONE ROOM
OR STAYS STILL (P=.25). AFTER THAT, IF HE IS WHERE YOU
ARE, HE EATS YOU UP (& YOU LOSE!)
YOU:
EACH TURN YOU MAY MOVE OR SHOOT A CROOKED ARROW
MOVING: YOU CAN GO ONE ROOM (THRU ONE TUNNEL)
ARROWS: YOU HAVE 5 ARROWS. YOU LOSE WHEN YOU RUN OUT.
EACH ARROW CAN GO FROM 1 TO 5 ROOMS. YOU AIM BY TELLING
THE COMPUTER THE ROOM#S YOU WANT THE ARROW TO GO TO.
IF THE ARROW CAN'T GO THAT WAY (IE NO TUNNEL) IT MOVES
AT RANDOM TO THE NEXT ROOM.
IF THE ARROW HITS THE WUMPUS, YOU WIN.
IF THE ARROW HITS YOU, YOU LOSE.
WARNINGS:
WHEN YOU ARE ONE ROOM AWAY FROM WUMPUS OR HAZARD,
THE COMPUTER SAYS:
WUMPUS- 'I SMELL A WUMPUS'
BAT - 'BATS NEARBY'
PIT - 'I FEEL A DRAFT'

The rooms are the vertices and the tunnels are the edges of this graph. To find
out whether a target room can be reached from a source room using a given amount
of tunnels, one can do a breadth first search on the underlying undirected graph.
BFS works like this: start with the source vertex, maybe it is already the target? If not, then go a level deeper and find out, if one of the children (also called successors) of the source vertex is the wanted target. If not, then for each child, go a level deeper and find out if one of the grand-children is the wanted target. If not, then for each grand-child go a level deeper and so on.
The following is a recursive implementation of BFS. You will not find any loops (for, while). Instead you manage two lists. The first one ('stack') contains all the vertices of the current depth-level (e.g. all grand children). The second ('visited') contains all vertices that you already checked. Now there are three possibilites: Either stack is empty, then all vertices have been checked unsuccessfully; or the target vertex is a member of the stack, then you are happy; or the target is not a member of the stack, but there are still some vertices that you did not visit, then you append to the stack, all successors of the members of the stack and the old stack now belongs to the visited vertices.

<lang red> Red [ Title: "Hunt the Wumpus" ;Date: 25-Jun-2016 Author: "Gregg Irwin" Version: 1.0.2 Comment: { 2001 Notes: I found an old version, in C (by Eric Raymond), which was adapted from an even older version, in BASIC (by Magnus Olsson), that had been found in a SIMTEL archive. It's got lineage.
As of 22-Oct-2001, it appears to work, though I haven't traced the arrow path'ing logic yet nor made it smart. Arrows can go pretty much anywhere you tell them and, yes, you can shoot yourself as in the original.
I tweaked a few strings, but the instructions are almost unscathed.
Ahhh, it takes me back to my Dad's HP85 with the built-in 5 inch monochrome screen, tape drive, and thermal printer...
2016 Notes: This was one of the very first programs I wrote in REBOL. I could update it, but we all have to start somewhere, and I think it has a certain charm. It is neither concise, nor idiomatic Redbol (a portmanteau of Red and Rebol), but making it so will be a good exercise for the reader, if they so choose. And if they don't, that's fine too, because you can write your Red code however you want.
And for the kids out there, my Dad's HP85 was a beast. He paid a LOT of money to get the extra 16K RAM module. 32K RAM total. Believe it. Only 36 years ago. } history: { 1.0.0 22-Mar-2001 {Initial Release} 1.0.1 11-Apr-2002 {Fixed bug where the Wumpus might eat you after you shot him.} 1.0.2 25-Jun-2016 {Ported to Red 0.6.1} } ]

WELCOME TO 'HUNT THE WUMPUS'
THE WUMPUS LIVES IN A CAVE OF 20 ROOMS. EACH ROOM
HAS 3 TUNNELS LEADING TO OTHER ROOMS. (LOOK AT A DODECAHEDRON TO SEE HOW THIS WORKS-IF YOU DON'T KNOW WHAT A DODECAHEDRON IS, ASK SOMEONE)
HAZARDS:
BOTTOMLESS PITS - TWO ROOMS HAVE BOTTOMLESS PITS IN THEM
IF YOU GO THERE, YOU FALL INTO THE PIT (& LOSE!)
SUPER BATS - TWO OTHER ROOMS HAVE SUPER BATS. IF YOU
GO THERE, A BAT GRABS YOU AND TAKES YOU TO SOME OTHER
ROOM AT RANDOM. (WHICH MIGHT BE TROUBLESOME)
WUMPUS:
THE WUMPUS IS NOT BOTHERED BY THE HAZARDS (HE HAS SUCKER
FEET AND IS TOO BIG FOR A BAT TO LIFT). USUALLY
HE IS ASLEEP. TWO THINGS WAKE HIM UP: YOUR ENTERING
HIS ROOM OR YOUR SHOOTING AN ARROW.
IF THE WUMPUS WAKES, HE MOVES (P=.75) ONE ROOM
OR STAYS STILL (P=.25). AFTER THAT, IF HE IS WHERE YOU
ARE, HE EATS YOU UP (& YOU LOSE!)
YOU:
EACH TURN YOU MAY MOVE OR SHOOT A CROOKED ARROW
MOVING: YOU CAN GO ONE ROOM (THRU ONE TUNNEL)
ARROWS: YOU HAVE 5 ARROWS. YOU LOSE WHEN YOU RUN OUT.
EACH ARROW CAN GO FROM 1 TO 5 ROOMS. YOU AIM BY TELLING
THE COMPUTER THE ROOM#S YOU WANT THE ARROW TO GO TO.
IF THE ARROW CAN'T GO THAT WAY (IE NO TUNNEL) IT MOVES
AT RANDOM TO THE NEXT ROOM.

// This is an implementation of the old game called Hunt the Wumpus. // // You can read about it here: https://en.wikipedia.org/wiki/Hunt_the_Wumpus // // Here's a quick summary: // // You are in a maze of 20 rooms, numbered 1 through 20. Each room is connected to // 3 other rooms. There is no light in the maze, and the game will tell you which // rooms are connected to the one you're in. The maze layout and numbering is the // same for every game. At the time of writing, the Wikipedia page above has an // image showing the layout and numbering. // // In the maze is a Wumpus, 2 bottomless pits and 2 super bats. You will die if you // are in the same room as the Wumpus or if you fall into one of the pits. // If you enter a room where a super bat is you will be transported to another // random room. // // You can move about the maze by entering one of the connecting rooms. // If a connecting room contains the Wumpus, a pit or a super bat, the game // will let you know that they are around but not which room they are in. // // To win you need to kill the Wumpus. You have 5 arrows at your disposal that // may be shot through up to 5 connected rooms, and if your arrow passes through // the room containing the Wumpus then it dies and you win. If your arrow // misses it will wake the Wumpus up and it will move randomly through the maze.
