Asteroids

This is a "game" I wrote in 2010, with some minor changes to make it compile using stable libraries. It's really just a demo for a 2D vector graphics engine and a particle system.

I've spent a few hours in 2022 cleaning it up:

• Now builds with a stable version of Allegro
• Untangled some cyclic dependencies (the module dependencies now form a DAG)
• Replaced libboost with C++17 standard library
• Replaced a lot of ugly iteration with ranged-for or STL algorithms

It's still not particularly good code:

• It leans heavily on a crutch made of shared_ptrs. Most of these could be unique_ptrs or even direct data members.
• There are some complex loops I didn't take the time to fully recomprehend - these can probably be simplified by decomposition into STL algorithms.

Dependencies

You'll need Allegro 5, including the development headers, along with the usual g++ toolchain. To install these dependencies on Ubuntu, just run sudo apt install build-essential liballegro5-dev.

Building

1. Install the dependencies.
2. Build the application by typing make.
3. Run the application by typing ./asteroids.

Controls

Arrow keys rotate/accelerate. Spacebar fires an asteroid. Use the asteroids to destroy the asteroids.
