This project consists of the implementation of a robust TicTacToe game client that communicates over UDP. The client is capable of functioning over a bad network. The client will be able to detect duplicate packets as well as malformed packets and will also be able to reissue dropped packets. In the case of a dropped connection with a server, the client will send out a multicast request to look for any available servers and resume the game state with the first available server.
Packet Format
| 1Byte | 1Byte | 1Byte | 1Byte | 1Byte | 1Byte |
|---|---|---|---|---|---|
| uint32 | uint32 | uint32 | uint32 | uint32 | uint32 |
| version number | command code | response code | move position | turn number | game number |
Board Representation
| 1 | 2 | 3 |
| 4 | 5 | 6 |
| 7 | 8 | 9 |
Command Codes
- 0: Move Command (from client/server) .Send with first move (from server)
- 1: New Game Request (from client to server)
Response Codes (Version 3)
- 0: OK
- 1: Invalid Move - The requested move cannot be performed given the current board configuration
- 2: Game out of sync - The turn number received is invalid (out of sync)
- 3: Invalid Request - Any other invalid request
- 4: Game over - Sent along with game ending (win/tie) move
- 5: Game over Acknowledged - Sent as acknowledgment of Game Over
- 6: Incompatible Version Number - The version number received is incompatible with the local version
- 7: Server is busy - The server cannot accept a new game right now
- 8: Game Number Mismatch - The game number received is not valid
- Navigate to the directory where tictactoeClient.c, utility.c, utility.h and the makefile exist
- Run the make command and then the executable as shown below
- Client is statically set to bind to port 5001
term2$ make
term1$ ./tictactoeServer <port> <botlevel>
term2$ ./tictactoeClient <port> <server-ip>
- Progression of game on the client
- Progression of game on the Server
