\section{Zuul bad}





\section{Zuul better v1}

\subsection{printLocationInfo}

This code duplication has been previously avoided with the printRoomInfo()
method.
It has been renamed to printLocationInfo(), as part of the commit e52a34789, to
match the exercise.

\subsection{getExit}

The exit attributes have been made private and a getter was added in commit
53c427ff3. A switch statement has been used instead of multiple if statements.

\subsection{getExitString}

This method has been added as part of commit ca65af2e2.

\subsection{HashMap, setExit}

Room exits are now stored in an HashMap since commit c9d890b9b. The setExits()
method has been replaced by setExit() which takes advantages of the HashMap.

\subsection{Vertical direction}

In commit 4145a5e8c, the getExitString() method has been modified to be able to
print the availability of the new exits, used in the stairwell at wing 3. Due
to the architecture of these rooms, the side exits that were previously settled
to link them have been kept.

\subsection{keySet ?}

The keySet() method of the class HashMap returns a Set of the keys contained in
the map.

\subsection{getExitString ?}

The getExitString() method returns a String listing the room's exits.
To achieve that, it iterates through the exits Map's keys, that is a Set of
Strings, appending each one to the String that it returns.

\subsection{getLongDescription}

The Room class now uses the previously explained getExitString() method and
includes the getLongDescription() method that returns the full description of
the room since commit e510b08d0.

\subsubsection{Changes on execution}


\section{Zuul with features}

\subsection{look}

The look command has been added with the commit 698e3cd25.

\subsection{eat}

The eat command has been added with the commit 40b9b4816.


\section{Zuul better v2}

\subsection{showAll, showCommands}

This modifications are part of the commit 79d33230b.

\subsection{Adding commands}

Adding new commands would not require modifying the printHelp() method anymore.
However, adding new commands and related functions would still require editing
the Game class and its processCommand() method.

\subsection{getCommandList}

The command list is not printed in the CommandWords class anymore. Instead, this
class returns a String, forwarded by the Parser class, that is then printed in
the Game class, thanks to commit 5f1d0ada2.

\subsection{Comparison with reference}

The printLocationInfo() method, used only twice, has been trimmed by the commit
590a932e5 and has been replaced by a call to the getLongDescription() method of
the Room class.

A missing getter for the Room description has been added as part of the commit
f84606424.

The loop building the command list String has been modified to use an Iterator
with the commit 0c5793abf.

\subsection{StringBuilder}

The command list and the exit list are now created using a StringBuilder since
commit ee5ec33aa. This avoids the creation of a new String object at each
concatenation, and thus allows better performances.

\subsection{Room objects}

Rooms are now stored in an HashMap since commit f64f1ffb0, so they can be
passed to any method in any class.

\section{Zuul with images}

\subsection{Game, GameEngine, UserInterface}

The following methods was implemented as part of commit 54e102463.

\subsubsection{Game}

The constructor of this class instantiates the GameEngine and the UserInterface,
and set the output of the first to the second.

\subsubsection{GameEngine}

This class contains the attributes and methods previously contained in the Game
class.

Instead of printing to the standard console output, it prints to the GUI.

\subsubsection{UserInterface}

This class implements the graphical user interface of the game. It basically
creates the different window components and provides methods to
interact with them.

\subsection{Parser/Scanner}

Since commands are entered through a text field instead of the console, the
use of Scanner that read from the standard system input is not required anymore.

\subsection{addActionListener() and actionPerformed()}

The addActionListener() of an object x takes as parameter an object y that have
a actionPerformed() method. When an action event occurs on x, this method on y
is called and an ActionEvent is passed as parameter.

The actionPerformed() method then does the appropriate action according to the
event that happened.

\subsection{Add a button}

A help button was added with commit 7f153a4c1. The processCommand() method was
modified to take the command String as parameter instead of reading it only from
the text field, and the actionPerformed() method was modified accordingly to
forward the command.
