A modern C++ implementation of the classic arcade game Galaga using the Cinder framework for graphics and gameplay.

This project recreates the core mechanics of Galaga with the following features:

• Player-controlled battleship that can move and shoot
• Enemy ships that move downward in formations
• Score tracking with persistent high score
• Multiple lives system
• Increasing difficulty through levels
• Arcade-style visuals and custom font

• CMake 3.12+
• C++11 compatible compiler
• Cinder graphics framework
• Visual Studio 2019+ (Windows) or Xcode (macOS)

1. Clone the repository
2. Install the arcade font from resources/arcade_font.TTF
3. Build using CMake:

mkdir build
cd build
cmake ..

4. Open the generated project files in your IDE
5. Build the galaga-game target

Launch the compiled galaga-game executable.

• Left/Right Arrow Keys - Move battleship
• Z - Fire bullet
• Close window to exit

The game is structured around these key components:

• Space - Main game container managing all entities
• GalagaApp - Cinder application wrapper handling rendering and input
• Battleship - Player-controlled ship
• Enemy - Enemy ships with movement patterns
• PlayerBullet - Projectile physics

The architecture uses modern C++ practices and is thoroughly unit tested using Catch2.

Run the unit tests by building and running the galaga-test target.

• High scores are persisted in resources/highscore.txt
• The game has no win condition - aim for the highest score possible
• Each level increases enemy count by 3x
• Each enemy destroyed awards 50 points
