TankMaster

Project Title: TankMaster

Introduction:

The project aims to develop a local multiplayer tank shooter game. A tank shooter in which each player controls their tank, and fires their cannon. The player to get most kills in a certain time wins!

Mechanic:

A tank can shoot a cannonball from it's ammo, which has a size of 5, and refills slowly after the ammo is over. There is a minimum delay between each shot. The shot cannonballs can reflect from the walls, can collide with each other and explode, can reflect from obstacles, or can collide with a tank and cause the other player to score. Each match has a timer set by the user, the player to do the most kills in the given time wins. In case of more than 2 players, players are divided into red and green teams. Friendly fire is disabled, and the team to get most kills wins!

Objectives:

• Apply the concepts of programming and math to create the core mechanics including cannonballs, tank movements, collision, and more.
• Apply the concepts of data and networking to serialize and send data accross a network to keep clients in sync.
• Engage the users in amazing deathmatches, provide them with enjoyment and have them keep playing for the maximum possible time.
• Learn to use all SFML modules, from window to graphics and sound to network.

Features and Functionalities:

• Players can make moves by using WASD or Arrow keys, in case of network multiplayer, both map to their tank, but in case of offline, WASD controls the green tank, arrow keys control the red tank.
• Realtime collision detection, optimization of collision detection, management of large arrays of positions and velocities of objects, and rendering of those objects in the right order.
• Data serialization and local network multiplayer using a self-made protocol that runs on port 6767. This protocol follows the decentralized peer-to-peer architecture, where initially, every device is broadcasting and listening for other devices, as soon as a device invites another to a match, the one that accepts would become the server. The other device would stop broadcasting, though, any other devices than these two on the network can be invited by the server, or can request the server to join the match, upon joining which, the devices become clients too.
• Win conditions and winning message, main menu screen, settings screen.
• Allow players to choose a username.
• Provide a pause menu and option to resume the game or exit to main menu, or provide further options. The gameplay doesn't pause in case of multiplayer.
• Management and dynamic scaling of window in case of WindowResize events.

Limitations:

• Use of functions is not allowed
• Use of arrays greater than 1D is not allowed
• Use of data structures other than array is not allowed 
• Use of more than one source file is impossible as functions are not allowed
• Use of custom classes or data structures is not allowed
• Use of any library except SFML/*.hpp, sstream and cmath is not allowed
