+# 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).
