Features

• This repo has been updated on 26/09/2023, integrating some Sanitizers and all warnings enabled as errors, surely this code has not been revised, I SAW SOME LEAK SANITIZER ERRORS can I won't solve them right now.
• Using SDL3 just as graphic api.
• C++17 features:
  • Smart pointers.
  • Lambdas.
  • Algorithm lib.
  • Etc...

File Structure

• Assets: Assets files, to display on the screen (link below).
• githubResource: This is a folder with some images to this README.
• src/components: Components used on the game.
• src/game: Game files, as Main Menu, or Game State.
• libs: Libs to store SDL and dependencies.
• src/systems: Some systems.
• src/tinyECS: Core tinyECS.
• src/main.cpp: main file.

Installation and compilation

Dependencies

• CMake 3.27 or later
• A build tool like Ninja, GNU Make or Visual Studio
• A C++23-compliant compiler, such as:
  • GCC 13 or later
  • Clang 16 or later
  • Visual Studio 2022 or later

Using CMake (preferred):

CMake presets:

• gcc:
  • gcc_debug
  • gcc_release
• clang:
  • clang_debug
  • clang_release
• Windows MVSC (Visual Studio 2022):
  • wind_debug
  • wind_release
• Windows Clang (Visual Studio 2022):
  • wind_clang_debug
  • wind_clang_release

Let's see an example with gcc_release as preset, but you can choose another from this list.

$ git clone --recurse-submodules https://github.com/parequena/SpaceInvaders
#               git submodule update --init # if fails
$ mkdir build
$ cd build
$ cmake .. --preset gcc_release
$ cd gcc_release
$ cmake --build . -j

Windows

As we don't have freetype on Windows, we need it for compiling

$ git clone --recurse-submodules https://github.com/parequena/SpaceInvaders
#               git submodule update --init # if fails
$ cd libs/SDL_ttf/
$ git submodule update --init external/freetype/
$ cd ../..
$ mkdir build
$ cd build
$ cmake .. --preset wind_release
$ cd wind_release
$ cmake --build . -j

TODO

• Create AI system.
• Create Collision system.
• Create HP system.
• Physics system.
• Improve menu.
• Improve string render (SDL_ttf).
• Changing the GameContext_t to another approach.
