#Test task for Data Monsters

Description

It is a test task (or a probation project) was performed as a part of application to a Scala Developer position of some company.

The project split in to subproject:

• streams/ where all main use-cases implemented by use of true Akka Actors
• actors/ where all main use-cases implemented by use of Akka Streams

Usage

Pure actors

Start game server

sbt actors/run

Connect game server

First player

telnet localhost 6600

and second one

telnet localhost 6600

Type SPACE and ENTER when see "3"

Akka Streams

Start game server

sbt streams/run

Connect game server

First player

stty -icanon && netcat 127.0.0.1 6600

and second one

stty -icanon && netcat 127.0.0.1 6600

##Requirements Use Scala/Akka.

##User stories

1. Player connects game server by use of telnet. 1.1. It's assumed that player's terminal uses UTF-8 encoding
2. After the connection is established the game greets the player with message "Привет! Попробую найти тебе противника" 1.1. hereinafter all messages is ended by "\n"
3. The server chooses other player among already connected players waiting for a peer competitor
4. After the peer found the server notifies both players by the message "Противник найден. Нажмите пробел, когда увидите цифру 3"
5. In randomized interval (2sec < T < 4sec) the server sends messages "1", "2" or "3" in random order to players
6. After "3" is sent, the game waits till one of the player sends space symbol.
7. The first player who sent a space symbol is a winner. 1.1. The winner receives a message "Вы нажали пробел первым и победили". 1.1. The looser receives a message "Вы не успели и проиграли". 1.1. Both are disconnected from the game.
8. If a player sends space symbol before the "3" was sent to him he becomes a looser 1.1. A message "Ваш противник поспешил и вы выйграли" is sent to the winner 1.1. A message "Вы поспешили и проиграли" is sent to the looser 1.1. Both are disconnected from the game.

##Assumption

1. For Pure Actors: Message from a player perspective is a number of symbols ended by newline character, so to send SPACE a player must type SPACE and ENTER from newline
2. The game ignores any strings except SPACE (" ")
3. For Akka Streams chosen is netcat because it was simpler for me to turn off user input buffering between a terminal and this application.
