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 beunique_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
- Install the dependencies.
- Build the application by typing
make. - Run the application by typing
./asteroids.
Controls
Arrow keys rotate/accelerate. Spacebar fires an asteroid. Use the asteroids to destroy the asteroids.
