## multiplayer_fps

### Instructions

Write your own version of the game [maze wars](https://www.youtube.com/watch?v=5V5X5SbSjns). You should recreate all the elements of the game, but you have freedom to implement the user interface.

### Objectives

#### User Interface

The game should present a specific User Interface, in which the minimum requirements are:

- A mini map where the player can see his own position and the whole "game world".
- The graphics of the game (walls and other players) should be similar to the original game (see [maze_wars](https://www.youtube.com/watch?v=5V5X5SbSjns) for more details)
- Finally you have to display the frame rate of the game on the screen.

#### Architecture

- A peer-to-peer network that will allow other players to join your server and play against each other.
- Your implementation should allow one client and the server to run in the same machine and all the other clients to connect from different computers.
- Use the UDP protocol to enable the communication between the clients and the server.
- The game should have at least 3 levels with increasing difficulty (with difficulty we mean, making the maze harder, with more dead ends).

You will have to develop the game server and also a client application:

- The server must accept as much connections as possible (the minimum should be 10).
- When the client is initialized, the game should ask for:
  - The IP address of the server, allowing the client application to connect to any server.
  - A username in order to distinguish users.

After providing the above information, the game should start and open the graphical interface, in which the player should join and start playing the game.

Example:
Assuming that you can connect to a server in the same computer.

```console
$ cargo run
Enter IP Address: 198.1.1.34:34254
Enter Name: name
Starting...
$
```

#### Performance

The game should always have a frame rate above 50 fps (frames per second).

### Bonus

As bonus for this project here are some ideas:

- Implement a level editor to allow player to create their own mazes.
- Implement an algorithm that generates automatically new mazes.
- Implement A.I. players to allow playing the game without having to wait for more people to join to the server.
- For the basic implementation you can initialize the game from the command line. As a bonus you can implement the initialization of the game as part of the graphical interface and save a history of the hosts with an alias so it's easier to reconnect to known servers.

This project will help you learn about:

- GUI applications
- Game mechanics
- [UDP protocol](https://searchnetworking.techtarget.com/definition/UDP-User-Datagram-Protocol)
