Jetpack

Description

Jetpack is a multiplayer game inspired by Jetpack Joyride, developed in C/C++. The game uses a custom TCP-based protocol, allowing two players to compete simultaneously.

It consists of:

• A server (jetpack_server) that manages game logic and client communication.
• A client (jetpack_client) that handles game rendering and player input.

Features

• Custom network protocol using poll(2).
• Multiplayer gameplay with at least two players required to start.
• Game elements including maps, coins, and obstacles.
• Server-controlled collisions to prevent client-side cheating.
• Graphical interface using an authorized library (SFML, SDL, etc.).
• Debug mode (-d flag) for logging network packets.

Installation

Prerequisites

• A C/C++ compiler (e.g., gcc or g++).
• make to build the project.
• A supported graphical library (e.g., SFML, SDL).

Compilation

Use the provided Makefile to build the project:

# Compile both client and server
make all

# Compile only the client
make client

# Compile only the server
make server

To clean compiled files:

make clean   # Remove object files
make fclean  # Remove binaries and object files
make re      # Clean and rebuild everything

Usage

Running the Server

./jetpack_server -p <port> -m <map_file> [-d]

• <port>: Port to listen on.
• <map_file>: Path to the game map file.
• -d (optional): Enable debug mode to log network packets.

Example:

./jetpack_server -p 4242 -m maps/level1.txt -d

Running the Client

./jetpack_client -h <server_ip> -p <port> [-d]

• <server_ip>: IP address of the server.
• <port>: Port to connect to.
• -d (optional): Enable debug mode.

Example:

./jetpack_client -h 127.0.0.1 -p 4242 -d

Documentation

• The network protocol and map format are fully documented in doc.txt (formatted as an RFC).
• Players can collect coins (score points) and must avoid electric obstacles (instant death).
• The game ends when:
  • A player reaches the end of the map.
  • A player dies (the other wins).
  • Both reach the end, and the one with the highest score wins.
