Done building the words database...
In the example above, the following Prolog KB will be constructed.
word(horse,animals).
word(panda,animals).
word(hello,greetings).
word(banana,fruits).
word(bison,animals).
word(hoard,collections).
After the KB building phase, the game play phase begins. The game displays to the user the available categories to pick one from. The player is then prompted to pick a length and category for the word to be guessed. The game picks a word of the given length and category and the guessing game begins. The player is allowed a maximum number of guesses equal to the entered length plus one. In each guess, the user must enter a word of the chosen length. The game then displays to the user the correctly entered letters (not necessarily in correct positions), and the correctly entered letters in correct positions. Below is a sample of the interaction between the game and the player in the game play phase based on the example KB provided earlier.
The available categories are: [animals,greetings,fruits, collections]
Choose a category:
|: animals.
Choose a length:
|: 9.
There are no words of this length.
Choose a length:
|: 5.
Game started. You have 6 guesses.
Enter a word composed of 5 letters:
|: hello.
Correct letters are: [h,e,o]
Correct letters in correct positions are: [h]
Remaining Guesses are 5
Enter a word composed of 5 letters:
|: hell.
Word is not composed of 5 letters. Try again.
Remaining Guesses are 5
Enter a word composed of 5 letters:
|: hoard.
Correct letters are: [h,o,r]
Correct letters in correct positions are: [h,o]
Remaining Guesses are 4
Enter a word composed of 5 letters:
|: horse.
You Won!
