Technical overview:

In this project we used:

• MVC pattern
• Extended visitor pattern
• Command dispatching pattern
• Mixed key dictionary
• Java RMI
• Java Multithreading
• Asychronous message passing
• Client/Server architecture
• NASA World Wind Java as geographical model

System Architecture

• Using the common API as the message passing infrastructure, we implemented our game following the API guidelines and communication protocols.
• Our game are based on the server-client architecture, which are implemented as a set of customized commands in the server side.
• The communication between various of commands are done using ICmd2ModelAdaper.put() and get() method via a common local data storage.
• The communication from the client back to server are done using ICmd2ModelAdaper.sendTo() method, with the target recipient being the server.
• The communication within the team (intra-team communication) are done using ICRCmd2ModelAdaper.sendToChatRoom() method, i.e. a non-routing way.
• The communication between different teams (inter-team communication) are done by sending the message back to the server.

Game Instruction

1. Start the client 1.1 Run "sengoku-game/GameClient.launch" to start the client; 1.2 enter desired username; click "Start" button to initiate the client.

2. Start the server 2.1 Run "sengoku-game/GameServer.launch" to start the server.

3. Client connect to server On game client side, input the Server's IP address in "Remote IP" and click "Connect to" to connect to the Game Server.

4. Game Installation 4.1 Team assignment Team assignment is auto-done when clients connected to the server. 4.2 Game installation On the game server side, click "Send Sengoku Game" to send the sengoku game to all players; click "Send Game" to send the demo game to all players.

5. Game user manual (Two Games)

   5.1 Demo game (Guess the number)

   Note : Demo game is a game we used to test our API, which is included in the milestone one and is not a part of our final game. * In the client game GUI, Input your guess on the text field and click "guess" to make a guess. * The correct answer is 50. * Server will notify within you team (you can check this if you carry out Step 3) "10 too small!" if your guess is 10 which is smaller than 50 and "70 too big!" if your guess is 70 which is greater than 50. * Server will nofity the win/lose message among all teams -- you'll either receive "50 Bingo! You have won the game!" or "You lose the game!".

   5.2 Sengoku Game

   Back ground

   • This is a real-time-strategy (RTS) game.
   • Each team is a Kingdom consisting of several war lords (team members).
   • While belonging to the same country, war lords are independent from each other in making their own game decision to optimize the Kingdom’s overall population growth and land conquering.
     • There dozens of cities in the map, NYC, LA, Houston, etc.
     • At the beginning of the game, each player (war lord) is assigned to a random city with 500 soldiers. Other cities are occupied by creeps (controlled by computer).

     • Each action includes:
       • 1. selecting a base city -- in which you MUST have armed forces)

       • 4. confirm your action.
   • If the target city belongs to your own Kingdom, then your are MIGRATING your army from base city to target city.
