Breakout on Sextant

This project implements a multiplayer Vintage Breakout game running directly Sextant. It was developed as part of our Operating Systems UE at IMT Atlantique.

Features

• Two-player platform controls using keyboard input
• Auto-moving enemy platform
• Ball management (spawn, movement, collisions)
• Brick wall that resets when cleared
• Score display
• Buffered VGA rendering (mode 13h)

Controls

• Player 1: s (left), d (right)
• Player 2: j (left), k (right)

Balls spawn periodically up to a limit of 2 simultaneously and destroy bricks on contact. The score increases as bricks are removed.

Requirements

To build and run this project, you need:

• make
• gcc and g++
• nasm
• qemu-system-x86_64

Optional: VSCode with DevContainer support for development.

How to Build and Run

From the project root:

make clean && make && make run_gui

Project Structure

• Applications/ — Game entities: ball, platform, brick, scoreboard
• drivers/ — Low-level keyboard, timer, screen handling
• sextant/ — Kernel subsystems: threading, memory, interrupts
• hal/ — Boot and multiboot setup
• Makefile — Build instructions

Notes

• All rendering is done using VGA mode 13h with offscreen buffering
• Input is handled via IRQ-based keyboard interrupt
• Timing and scheduling rely on periodic IRQ0 timer interrupts
