A classic video game is developing for training in creating and maintaining large codebase

• Used SFML, RapidJSON, GTest, better-enums.
• Cross-compilation on CMake 3.27: MSVS2019/MinGW-w64.

• Controller, Core
  • ListenersEmitters - observer pattern interpretation in Qt/UE manner.
  • LowLevelApplication - it handles I/O from windows level, organizes a game loop.
  • Application - it a singleton contains all globally needed semi-related to ECS resources (configs, textures, etc).
• Model, Simulation, ECS
  • Each of Component holds a map of <EntityPtr, UserComponent>.
  • Each of Entity can claim/reject a Component and get the value of it.
  • Each of System contained in and updated by a Level class.
    • Each of UserLevel provided by a LevelProvider that delegates level creating to a LevelCreatorsStorage.
    • LevelCreatorsStorage holds unique lazy creator-function taken from static-initialization stage for each UserLevel.
• View, Menus and Layers
  • Still as a stub.

• Structure-intrusive automatic serialization solution like a code generation in UE.
  • Used a lot of C++20 concepts for replacing SFINAE.
  • Main classes:
    • SerializableBase - is common staff for serialization via RapidJSON.
    • SerializableStruct - is container and base class for user structure contains several SerializableVariable and/or SerializableStructs. It iterates recursively on self members.
    • SerializableVariable - it contains an object of RapidJson-supported literal type or third-party type which defined fromJson/toJson in GameJsonConversions/StdJsonConversions structures.
  • For user-usage defined several macro e.g. SERI_V(...), SERI_S(...) & SERI_C(...), etc.
  • TODO: Implement a serializable representation of std::vector, std::array/c-array.
• FrameByFrame - is an encapsulation of a sprite-sheet png-file
  • For each png-file exists a ConfigTexture object describes name, frame rate, frame size, origin, orientation, etc.
  • TextureProvider - it used for create FrameByFrame object. When application starts, it loads all textures that enumerated in a ConfigTextures object via visitor pattern implemented in a SerializableStruct class via iterating on internal structure-members array.
