Akkaships

Battleship game implemented in Akka. Training project for Codemotion 2015

Slides from the workshop are available at Slideshare

Requirements

Apache Cassandra

To start cassandra:

> $CASSANDRA_HOME/bin/cassandra -f 

To start CQL Shell:

> $CASSANDRA_HOME/bin/cqlsh

Requirement metadata:

CREATE KEYSPACE IF NOT EXISTS akkaships WITH replication = {'class': 'SimpleStrategy', 'replication_factor' : 1}
CREATE TABLE IF NOT EXISTS akkaships.users (user text, PRIMARY KEY((user)))
CREATE TABLE IF NOT EXISTS akkaships.statistics (user text, ts timeuuid, hit boolean, sunk boolean, PRIMARY KEY((ts),user,hit,sunk))

Execute Game mode localhost

First it is necessary to compile:

mvn clean install

Now it's time to execute the server

mvn exec:java -pl Server -Dexec.mainClass="es.codemotion.akkaships.server.ServerApp"

Once server is started it is possible to start the Player

mvn exec:java -pl Client -Dexec.mainClass="es.codemotion.akkaships.client.PlayerApp"

Configuration for a distributed environment

Player Configuration is in the file $AKKASHIPS_HOME/Client/src/main/resources/player-reference.conf and there it's necessary to change ...

player.akka.remote.netty.tcp.hostname = "[Your IP]"
player.akka.cluster.seed-nodes = ["akka.tcp://ShipsServerCluster@[ServerIP]:61000"]

Server Configuration is in the file $AKKASHIPS_HOME/Server/src/main/resources/server-reference.conf and there it's necessary to change ...

akkaships-server.akka.remote.netty.tcp.hostname = "[ServerIP]"
akkaships-server.akka.cluster.seed-nodes = ["akka.tcp://ShipsServerCluster@[ServerIP]:61000"]

Now it's time to recompile and follow the steps of the previous steps
