TicTacToe-Android

A school-project Android TicTacToe game that works locally using Java Sockets.

The clients and servers communicate using Sockets/ServerSockets and JSON messages, each message has a message_type to identify the scope of the message. There are two entities, a GameServer and a GameClient.

GameServer

This is a ServerSocket that handles two GameClient(s) and the game logic/validation.
There are 5 message types that are sent from the server to the clients:

game_start

Sent to both GameClients after they connect to the server

{
	message_type: 'game_start',
	player_id: 2,  // player 1 or player 2
	enemy_id: 1,   // player 1 or player 2
	max_rounds: 3  // For how many rounds to play the game
}

board

Contains the board and the id of the player that has to make the move. If the player does an illegal move he will receive the board back with the same next_turn_player_id

{
	message_type: 'board',
	next_turn_player_id: '1',
	board: [
		[,,], [,,], [,,]
	]
}

end_round

Marks the end of a round, the board is refreshed

{
	message_type: 'end_round',
	player_1_score: 0,
	player_2_score: 1,
	current_round_count: 1
}

end_game

Marks the end of a game, sends the win conditions

{
	message_type: 'end_game',
	player_1_score: 0,
	player_2_score: 1
}

disconnect

Received from client Y if client X disconnects

{
	message_type: 'disconnect'
}

GameClient

There is 1 message that the client sends to the server

make_move

Makes a move on the board

{
	message_type: 'make_move',
	player_id: 1, // Used to identify who is making the move (1 or 2)
	row: 0,
	col: 0
}
