Space Invaders SDL

This is a Space Invaders clone written in C++ using SDL 2. It features an ECS heavily inspired by Austin Morlan's blog post:

I have recorded a demo of the game in action, since I can hardly expect you to be able to build it:

Building

To build and run the game, you will need a C++20 compiler, CMake, SDL2, SDL2_image, SDL2_ttf, SDL2_mixer and (admittedly pointlessly) glm.

You can then just build as you would with any CMake project.

This will probably only compile on Linux with GCC or Clang, but I won't stop you from trying to get it working on Windows.

TODO

• Animations:
  • Animation component (src_rect).
• Alien Death Explosions
• More alien sprites: Cycles for green, + red and blue(?)
• Mothership: Flies along the top; fast; bonus points.
