\section{The puzzle}

Try to find the positions of the ships listed below the puzzle. The numbers on the side of the puzzle reveals how many ship segments can be found in the rows and columns. All remaining fields indicate 'water'. Consider the following rules: The ships are arranged horizontally and vertically. No ship touches another ship at any point, not even diagonally. Here's a little self-explanatory example:

\begin{center}
  \begin{battleship}
    \placesegment{4}{1}{\ShipR}
    \shipH{4,1,2,2,2}
    \shipV{3,1,4,0,3}
    \shipbox{3,3,2,2,1}
  \end{battleship}
  \hspace{1cm}
  \begin{battleship}
    \placeship{V}{1}{1}{3}
    \placeship{H}{1}{5}{2}
    \placeship{H}{3}{1}{2}
    \placeship{H}{3}{3}{3}
    \placeship{H}{5}{5}{1}
    \shipH{4,1,2,2,2}
    \shipV{3,1,4,0,3}
  \end{battleship}
\end{center}

\bigskip
\begin{lstlisting}
\begin{center}
  \begin{battleship}
    \placesegment{4}{1}{\ShipR}
    \shipH{4,1,2,2,2}
    \shipV{3,1,4,0,3}
    \shipbox{3,3,2,2,1}
  \end{battleship}
  \hspace{1cm}
  \begin{battleship}

\subsection[\texttt{sbshipscale}]{\styleoption{sbshipscale} (\underline{\texttt{1}})}
With the option \styleoption{sbshipscale}, you can scale the size of the ships in the ship box.
\section{Environments}
\subsection{\texttt{battleship}}
The \env{battleship} environment\marginnote{\hbadness=10000\RaggedLeft\scriptsize\envb{battleship}\oarg{options}\\\dots\\\enve{battleship}} is the central core of the style file. With the optional argument of the environment, you can reset the options with local scope. Here, a blank grid is created that you can fill with ships using other commands.
\section{Commands}
\subsection{Ships, water, islands, ...}
\subsubsection{\texttt{placeship}}
With the command \cs{placeship}\margcs{\cmd\placeship\{\marg{direction}\}\\\{\marg{column}\}\{\marg{row}\}\{\marg{length}\}} you can place complete ships in the grid. It expects the specification of the direction as horizontal (H) or vertical (V). Furthermore, it requires the starting coordinates and the length of the ship.
\subsubsection{\texttt{placesegment}}
The command \cs{placesegment}\margcs{\cmd\placesegment\{\marg{column}\}\{\marg{row}\}\\\{\marg{ship segment}\}} is used for the placement of ship segments in the grid. In the mandatory argument \marg{ship segment}, you can use the following commands:

\begin{center}
\begin{tabular}{lccl}
\cs{Ship} & \scalebox{.5}{\Ship} & \scalebox{.5}{\ShipC} & \cs{ShipC} \\
\cs{ShipL} & \scalebox{.5}{\ShipL} & \scalebox{.5}{\ShipR} & \cs{ShipR} \\
\cs{ShipB} & \scalebox{.5}{\ShipB} & \scalebox{.5}{\ShipT} & \cs{ShipT} \\
\end{tabular}
\end{center}
\subsubsection{\texttt{ship}}
The command \cs{ship} was replaced by the \cs{placesegment} command. The command \cs{ship} is deprecated and should not be used longer. It may still be used, but it is not recommended.
\subsubsection{\texttt{placewater}}
With the command \cs{placewater}\margcs{\cmd\placewater\{\marg{column}\}\{\marg{row}\}} you can place water markers ( \raisebox{2pt}{\Water} ) in the grid.
\subsubsection{\texttt{placeisland}}
With the command \cs{placeisland}\margcs{\cmd\placeisland\{\marg{column}\}\{\marg{row}\}} you can place islands ( \raisebox{-2pt}{\resizebox{!}{10pt}{\Island}} ) in the grid. The island outlines are created randomly: \raisebox{-2pt}{\resizebox{!}{10pt}{\Island}}, \raisebox{-2pt}{\resizebox{!}{10pt}{\Island}}, \raisebox{-2pt}{\resizebox{!}{10pt}{\Island}}, ...
\subsection{Presentation}
\subsubsection{\texttt{shipH}}
The command \cs{shipH}\margcs{\cmd\shipH\{\marg{csv list}\}} typesets the horizontal numbers above the grid. It expects a comma-separated list as an argument.
\subsubsection{\texttt{shipV}}
The command \cs{shipV}\margcs{\cmd\shipV\{\marg{csv list}\}} typesets the vertical numbers beside the grid. It also expects a comma separated list.
\subsubsection{\texttt{shipbox}}
The command \cs{shipbox}\margcs{\cmd\shipbox\{\marg{csv list}\}} defines the number and size of the ships, which are typeset under the grid.
\subsubsection{\texttt{definecounterstyle}}
The command \cs{definecounterstyle}\margcs{\cmd\definecounterstyle\{\marg{name}\}\\\{\marg{definition}\}} allows you to define your own styles. For example, the style \texttt{left} is defined as follows:

\begin{lstlisting}
\definecounterstyle{left}{
  \begingroup\reversemarginpar\marginnote{
  \tikz\node[shape=rectangle,fill=yellow!40,inner sep=7pt,
             draw,rounded corners=3pt,thick]
  {\Huge\puzzlecounter};}[-23pt]\endgroup
}
\end{lstlisting}

To typeset the counter into the margin we use the command \cmd\marginnote. We need to use the command \cmd\reversemarginpar\ to set the counter into the left margin. Of course, we must use this command in a group for local scope. Finally we use \cmd\puzzlecounter\ in a \cmd\tikz\ node with a vertical offset of 23 points.
\subsubsection{\texttt{puzzlecounter}}
The command \cs{puzzlecounter}\margcs{\cmd\puzzlecounter} provides the counter in textual form to use it for example in \cmd\definecounterstyle.
\subsubsection{\texttt{titleformat}}
With the command \cs{titleformat}\margcs{\cmd\titleformat\{\marg{format}\}}, you can define the format of the title. By default, the definition is as follows:

\begin{lstlisting}
\titleformat{\centering\Large\color{blue}}
\end{lstlisting}
\subsection{Miscellaneous}
\subsubsection{\texttt{battleshipsetup}}
With the command \cs{battleshipsetup}\margcs{\cmd\battleshipsetup\{\marg{options}\}} you can reset the options with global scope.
\subsubsection{\texttt{classicgame}}
The command \cs{classicgame}\margcs{\cmd\classicgame\{\marg{csv list}\}} typesets a game sheet for playing classic Battleship. It expects a comma separated list with the number and sizes of the ships.
\subsubsection{\texttt{setpuzzlecounter}}
With the command \cs{setpuzzlecounter}\margcs{\cmd\setpuzzlecounter\{\marg{number}\}}, you can reset the puzzle counter, for example before the solutions.
