BattleShips

Now With Exclusive Battle Royale Mode!

Running through gradle

Start up a server

./gradlew :battleships:run --args="server"
# Or for real time mode:
./gradlew :battleships:run --args="server --mode=ROYLE"

Then start some clients to join. This will start a swing terminal client even when ran from a terminal

./gradlew :battleships:run --args="client"

If you use the built jar, it will start normally in a terminal

./gradlew :battleships:build
cd battleships/build/libs
java -jar ./battleships-1.1.1.jar client

Check other options:

./gradlew :battleships:run # --args="help" # <- defaults to help
./gradlew :battleships:run --args="client help"
./gradlew :battleships:run --args="server help"

Using the built jar

java -jar battleships-1.0.0.jar

If you want to run the client on Windows use `javaw` instead of `java`! (Or use WSL)

(Lanterna can't use CMD or PS to display)

javaw -jar battleships-1.0.0.jar client

For everything else like reading the help prompts or running the server using java is fine

java -jar battleships-1.0.0.jar client -h

Build

./gradlew clean build

Test

./gradlew clean test

Run as application

./gradlew run

If for some reason VS Code throws an error upon running a debug session that it can't build the workspace, but the project can be built by hand, try cleaning it with Ctrl+Shift+P >Java: Clean the Java language server workspace

Throubleshoot

If the application looks blurry and you're using different scaling settings on windows other than 100%, try setting the Right-Click->Properties->Compatibility Tab's "Override the high DPI scaling behavior" to "System" on the java.exe/javaw.exe you're using. (Or use a WSL Shell)
