Tank Game with Artificial Intelligence

As a programming challenge module project, we develop this game using C# and XNA

 Game objectives are

• —clients acting as “tanks” accumulating points while making sure of their own survival.
• —The tanks are capable of shooting shells (bullets) and these bullets will move 3 times faster than a tank.
• —The environment is made out of four kinds of blocks
• —Brick wall 
• —Stone wall
• —Water
• —Blank cell

Brick Wall – Brick walls will be considered as obstacles. Players can shoot and break walls. 4 shots will break the wall and it becomes a blank cell

Stone – obstacles. cannot be shot. Bullets cannot pass through.

Water – Pits. Cannot go through but can shoot through

Game Initiation

• —A timer gets initiated when the first player resister for a game.
• When the 5th player joins the game or in the event of the timer expiring, the server will issue the game starting message to all the players that are already registered with the server.
• —As discussed before, any join request by a client hereafter until the end of the game instance will be rejected.
• —The game will be played in a 20x20 grid.

Joining the Game

—If the client’s request can be honoured, the server replies with a message in the following format.
S:P<num>: < player location x>,< player location y>:<Direction>#
—For an example the first player to register in a game instance may get a message like,
S:P1: 1,1:0#
—Direction
—0 North
—1 East,
—2 South
—3 West

—All other map details vary with each game instance and will be sent in the following format

I:P1: < x>,<y>;< x>,<y>;< x>,<y>…..< x>,<y>: < x>,<y>;< x>,<y>;< x>,<y>…..< x>,<y>: < x>,<y>;< x>,<y>;< x>,<y>…..< x>,<y># 

Moving And Shooting

—If the request direction is the same as the current direction, the server will try to move the client 1 cell in the said direction.
—Otherwise the tank will be rotated to face the requested direction

E.g.:
—If the tank is facing North and the client issues the command UP#, the server will try to move the tank up by 1 cell
—If the tank is facing North and the client issues the command DOWN#, the server change the tank direction to South. —

—When the client want to move/rotate their tank or shoot, it must issue the relevant command from the following list.
—UP#
—DOWN#
—RIGHT#
—LEFT#
—SHOOT#
—A client can issue one of these commands each second

—If the request of the client cannot be honoured due to some reason, it will be immediately communicated.
—OBSTACLE#
—CELL_OCCUPIED#
—DEAD#
—TOO_QUICK#
—INVALID_CELL#
—GAME_HAS_FINISHED#
—GAME_NOT_STARTED_YET#
—NOT_A_VALID_CONTESTANT#
—Otherwise the server will update its internal variables

—Once per second the server will broadcast a global update to all the clients documenting its internal variables about the clients.

G:P1;< player location x>,< player location y>;<Direction>;< whether shot>;<health>;< coins>;< points>: …. P5;< player location x>,< player location y>;<Direction>;< whether shot>;<health>;< coins>;< points>: < x>,<y>,<damage-level>;< x>,<y>,<damage-level>;< x>,<y>,<damage-level>;< x>,<y>,<damage-level>…..< x>,<y>,<damage-level>#

Acquiring Coins 

—For two reasons coins will appear on the map.

• —Random treasures 
• —Spoils of war 

The players are supposed to collect them by moving to the cell where the coin pile is.
When a player collect a pile of coins, their coin count and the point count will get increased by that amount—

The server will send the following message to signal the appearing event of a pile of coins.

C:<x>,<y>:<LT>:<Val>#
—x - <int>
—y - <int>
—LT -<int> the time that the pile of coins will be on the map before it automatically disappears
—Val – value of the coins

—There are three ways to acquire points
   —Breaking bricks -Each time a shell (bullet) from a player damages a brick wall, a constant amount of points is added to the player’s point count.
   —Collecting coins -—As described in the previous topic
—   Spoils of war 

Life Pack

—Similar to the piles of coins, life packs will appear on empty cells.
—The method of taking a life pack is similar to the method of taking a treasure.
—When a client takes a life pack, 20% of the initial health will be added to their health.
—Note that it is possible for a client, at some point of the game, to have a health value which is greater than the initial health value.

—The server will send the following message to signal the appearing event of a Life Pack.

L:<x>,<y>:<LT>#
—x - <int>
—y - <int>
—LT -<int> the time that the life pack will be on the map before it automatically disappears

Killing

—A bullet hit will reduce the health of a tank by 10% of the initial health
—A player who has health of 0% (or less) will die and drop their coins at the point of death. But they will not lose the current points. However 25% of the points of the victim will be added to the killer.
—The dropped pile of coins is no different from a randomly created pile of coins. Thus the killer do not have a claim on it, it can be picked up by any remaining client.

Penalties and Death

—If a client hits an obstacle (a standing brick wall or a stone wall), a fixed number of points will be deducted from the client.
—The deduction takes place per each turn, thus if a client keeps hitting an obstacle, it will continuously lose points. 

—As described in a previous slide, clients can shoot over water. But if the client tries to move the tank in to a cell with water, the client will be killed.
—Since there is no killer here other than the environment, no body will be credited with points and the coins of the slain client will not drop to the ground.
—But they will get their coin count set to zero nevertheless.

End Game

—The game ends if one of the following happens;
—All the clients are dead
—The game lifetime counter expires
—All the coin piles (random or otherwise) finished appearing on the map and all the appeared coin piles either has been claimed by a client or disappeared.
—When the game ends, the player with most points will be declared the winner. And the message GAME_FINISHED# will be broadcasted to all the clients.

How to install Joomla on WAMP server

This tutorial will teach you how to install a fresh copy of joomla into your wamp server. If you are a beginner to joomla, it is a content management system(CMS) that you can use to maintain a web site of your own. It is easier to test our site in local machine before it is hosted in the internet. So we use WAMP server(it works as a actual server, if you are linux user you can use LAMP)

If you are not familiar with WAMP or LAMP please refer these before continue.

How to install lamp on linux

What you need before start

• WAMP server must be installed on your pc
• check whether it is working or not by typing "localhost" on your browser, it will give you something like this.

if you get a browser window like above, you're ready to go. Otherwise please refer to your wamp installation tutorial again. you can use this one as well. Click here

Then follow these steps carefully.

Step 1

Download Joomla installation files from here

Joomla 3.0 is the newer version of Joomla( but here I'm using version 2.5.8)

You will get a zip file and extract it to wherever you want.

Step 2

Open your www folder, usualy this is located in C://wamp folder. 

www folder is the location we put all of our website files. so copy and paste your previously extracted joomla folder to the www folder. Let's name that folder as "My Site"

Step 3

Now we want to create a database for our web site. so open your browser and go to "localhost" by simply typing "localhost" on your browser address bar.

Then you will be directed to wamp server home page. Click on "phpmyadmin"

At there you can create a database for your web site. (I'm not going to describe it here)

Name your database as 'joomla' (you can use your own name)

Step 4

Locate your browser to "localhost".

At there you can see your joomla folder under My Projects, ( we named it as "My Site")

Click on the folder "My Site"

You will see a page like this.

You can select your preferred language for your installation. I leave it as English. Then click next.(upper right corner)

Then you will see the pre installation check window. 

Here you must see all the settings as 'green' except display errors and output buffering... you can switch off those two by simply using following steps. but it is not mandatory. 

Click on your wamp icon in the taskbar( lower right corner). select php> php settings

then deselect display errors and output buffering

now come back to your browser window and click "check again". now you must see all the things in green. if not please check your php settings and other relevant settings.

Click next

you will see the licence agreement. Read it and click next

Step 5

This is a critical part. now you can see the database configuration window. here we are introducing our previously created database to the joomla installation. 

select database type as "mysql"

host name is 'localhost'

then enter your mysql username and password, usually username is root and password is empty. But if you have changed them before you have to enter those changed values.

Enter the database name as 'joomla' ( you have to enter the database name as we created in the step 3)

leave other settings as it is.. Then click next

Step 6

now you are asked to create a FTP account. FTP account simply use to transfer files to your website. But here we don't need a ftp account just keep it as it is and click next.

Step 7

now you are almost done. Enter a site name. Then enter valid email address. Admin username and password. This user name and password is used to log into the back-end of your web site. all the configuration is done through this account. Just remember what you enter here.Click next

Step 8

In this window click "Remove installation folder" button. It will simply removes files which are used to install joomla on your server. Now you are done.

You can check your site by clicking "site" button on top right corner. You can visit your joomla administrator page by clicking "Administrator" button.
