-# Beispielprogramme des Programmierprojekts
-
-Hier ist der Quellcode für das in der Einarbeitungsphase genutzte Spiel
-_Battleships_ zu finden. Die Quellen bestehen aus den folgenden
-Gradle-Unterprojekten:
-
-* _:battleship:server_
-* _:battleship:client_
-* _:battleship:model_
-* _:battleship:converter_
-* _:common_
-* _:jme-common_
-
-_Battleships_ ist ein netzwerkbasiertes Spiel und besteht aus einem Server- und
-einem Clientanteil, die in den Unterprojekten _:battleship:server_ und
-_:battleship:client_ realisiert sind. Beide nutzen das Unterprojekt
-_:battleship:model_, das den gemeinsamen Modellanteil enthält.
-
-Die Unterprojekte _:common_ und _:jme-common_ enthalten Hilfsklassen.
-
-Das Unterprojekt _:battleship:converter_ wird für _Battleships_ selbst nicht
-benötigt, sondern enthält lediglich den Code, um ein im Spiel verwendetes
-3d-Modell eines Schlachtschiffs in eine _J3O_-Datei umzuwandeln, die von jME
-einfacher geladen werden kann.
-
-## 1 Vorbereitung
-
-Für das Programmierprojekt empfehlen wir die Verwendung von Java 20. Unter Linux
-sollte [_Eclipse Temurin_](https://adoptium.net/temurin/releases/?version=20)
-als JDK verwendet werden, andere JDKs können unter Linux Probleme verursachen.
-Auf anderen Betriebssystemen empfehlen wir aber ebenfalls Temurin. Im Folgenden
-ist beschrieben, wie Sie Temurin installieren und die Umgebungsvariable
-**JAVA_HOME** richtig setzen, damit Sie Gradle (siehe unten) verwenden können.
-
-### 1.1 Installation von Temurin
-
-Laden Sie [_Eclipse Temurin_](https://adoptium.net/temurin/releases/?version=20)
-entsprechend Ihrem Betriebssystem und Ihrer Prozessorarchitektur herunter und
-entpacken Sie das Archiv in einem Verzeichnis Ihrer Wahl auf Ihrem Rechner.
-
-### 1.2 Setzen von JAVA_HOME
-
-Zur Verwendung mit Gradle muss die Umgebungsvariable **JAVA_HOME** richtig
-gesetzt werden. Folgen Sie dazu den nachfolgenden Anweisungen entsprechend Ihrem
-Betriebssystem:
-
-* **Windows:**
-
-  Öffnen Sie ihre Powershell (Core) bzw. ihr Windows Terminal mit Powershell
-  (Core). Überprüfen Sie, ob die Umgebungsvariable korrekt gesetzt ist:  
-  `Get-ChildItem -Path Env:JAVA_HOME`  
-  Falls kein oder ein falscher Pfad gesetzt ist, setzen Sie diesen mit dem
-  folgenden Kommando (in einer Zeile):  
-  `[System.Environment]::SetEnvironmentVariable('JAVA_HOME','<Pfad zum SDK>',[System.EnvironmentVariableTarget]::User)`
-
-  Alternativ können Sie die GUI verwenden. Unter Windows 10 klicken Sie die
-  Windows-Taste und dann das Zahnrad um die Einstellungen zu öffnen. Dort wählen
-  Sie "System", dann "Info" (links unten) und nun
-  "Erweiterte Systemeinstellungen" (rechts) um den Dialog "Systemeigenschaften"
-  zu starten. Im Reiter "Erweitert" klicken Sie
-  "Umgebungsvariablen..." und klicken dann unter "Benutzervariablen" den Knopf
-  "Neu..." um JAVA_HOME anzulegen oder "Bearbeiten" um ihn zu ändern. Geben Sie
-  als Name `JAVA_HOME` und als Wert den Pfad ein. Schließen Sie mit "OK".
-
-  > **(!) Beachten Sie, dass Sie die jeweilige Applikation neu starten müssen**,
-  > um von der gesetzten Umgebungsvariablen Notiz zu nehmen.
-  > Dies betrifft auch die Shell, die Sie gerade verwenden.
-
-* **UNIX (Linux/MacOS):**
-
-  Öffnen oder erstellen Sie die Datei `~/.profile` (wenn Sie die Bash verwenden;
-  bei anderen Shells sind es andere Dateien) und ergänzen Sie am Ende der Datei
-  die Zeile:
-
-  `export JAVA_HOME="<Pfad zum entpackten Archiv>"`
-
-  Ersetzen Sie dabei `<Pfad zum entpackten Archiv>` mit dem entsprechenden Pfad.
-  Zum Beispiel:
-
-  `export JAVA_HOME="/home/user/jdk-20.0.2"`
-
-  Fügen Sie dann die folgende Zeile hinzu:
-
-  `export PATH="$JAVA_HOME/bin:$PATH"`
-
-## 2 Programmstart
-
-Grundsätzlich kann man das gesamte Projekt einfach in IntelliJ öffnen. Details
-dazu sind im Aufgabenblatt zur Einarbeitungsaufgabe zu finden. Im Folgenden ist
-beschrieben, wie die _Batttleships_ unmittelbar von der Kommandozeile gestartet
-werden können.
-
-Um _Battleships_ spielen zu können, muss man zuerst das Server-Programm auf
-einem Rechner und dann zweimal das Client-Programm auf beliebigen Rechnern
-starten, die TCP/IP-Verbindungen zum Server erlauben. Natürlich ist es auch
-möglich, alle drei Programme auf demselben Rechner zu starten.
-
-Es empfiehlt sich der Start von der Kommandozeile. Will man alle drei Programme
-auf demselben Rechner starten, sollte man dazu drei Shell-Instanzen öffnen und
-in jeder eines der Programme starten. Auf diese Weise können die
-Logging-Ausgaben der drei Programme voneinander unterschieden werden.
-
-Das Server-Programm startet man unmittelbar mit Gradle mit
-
-`./gradlew :battleship:server:run`
-
-Unter Windows kann es je nach Shell (Eingabeaufforderung cmd) erforderlich sein,
-`/` jeweils durch `\ ` zu ersetzen.
-
-Im Verzeichnis `battleship/server` befindet sich die Datei `config.propeties`,
-worüber sich der Server konfigurieren lässt. Mit der Zeile `port=1234` lässt
-sich der verwendete Server-Port (hier 1234) einstellen. Außerdem befindet sich
-dort die Datei `logging.properties`, womit das Logging des Servers konfiguriert
-wird.
-
-Das Client-Programm startet man unmittelbar mit Gradle mit
-
-`./gradlew :battleship:client:run`
-
-Die Datei `logging.properties` im Verzeichnis `battleship/client` konfiguriert
-das Logging des Clients.
-
-Alternativ kann man auch die Start-Skripte
-
-* `./battleship/server/build/install/battleship-server/bin/battleship-server`
-* `./battleship/client/build/install/battleship/bin/battleship`
-
-direkt in der Kommandozeile starten. Allerdings müssen sie zuvor mittels
-
-`./gradlew installDist`
-
-erzeugt worden sein. Beachten Sie aber, dass nur im **aktuellen
-Arbeitsverzeichnis** nach den Dateien `config.properties` und
-`logging.properties` gesucht wird und diese geladen werden. Das heißt, dass die
-vordefinierten Dateien in den Verzeichnissen `battleship/server` und
-`battleship/client` nur dann gelesen werden, wenn Sie diese Verzeichnisse als
-aktuelle Arbeitsverzeichnisse nutzen. Wie üblich müssen Sie dazu in der
-Kommandozeile
-
-`cd battleship/server`
-
-bzw.
-
-`cd battleship/client`
-
-eingeben.
-
-## 3 Hinweise zu _Battleships_
-
-Der _Battleships_-Client hat ein Menü, in das man immer mit der
-Esc-Taste kommt. Aus dem Menü heraus lässt sich das Programm auch schließen.
-Beachte, dass sich beim Laden und Speichern eines Spiels kein Dateidialog
-öffnet. Vielmehr muss man den Dateipfad in das Dialogfeld eingeben. Da
-JSON-Dateien geschrieben werden, empfiehlt sich das Datei-Suffix _.json_.
-
-## 4 Allgemeine Gradle-Tasks:
-
-- `./gradlew clean`
-
-  Entfernt alle `build`-Verzeichnisse und alle erzeugten Dateien.
-
-- `./gradlew classes`
-
-  Übersetzt den Quellcode und legt unter build den Bytecode sowie
-  Ressourcen ab.
-
-- `./gradlew javadoc`
-
-  Erzeugt die Dokumentation aus den JavaDoc-Kommentaren im Verzeichnis
-  `build/docs/javadoc` des jeweiligen Unterprojekts.
-
-- `./gradlew test`
-
-  Führt die JUnit-Tests durch. Ergebnisse sind im Verzeichnis
-  `build/reports/tests` des jeweiligen Unterprojekts zu finden.
-
-- `./gradlew build`
-
-  Führt die JUnit-Tests durch und erstellt in `build/distributions`
-  gepackte Distributionsdateien
-
-- `./gradlew installDist`
-
-  Erstellt unter `battleship/client/build/install` und
-  `battleship/server/build/install` Verzeichnisse, die jeweils eine ausführbare
-  Distribution samt Start-Skripten enthält (siehe oben).
