How To Build

Download SDL3-devel-3.2.22-VC.zip here https://github.com/libsdl-org/SDL/releases

Unpack into C:\libs Rename SDL3-3.2.22 to SDL3 Copy "C:\libs\SDL3\lib\x64\SDL3.dll" to AdvancedProgramming/PATH_TO_EXE for Debug and RelWithDebInfo(just a Release below in the text)

Run: cmake -S . -B build -DSDL3_DIR="C:/libs/SDL3/cmake" && cmake --build build --config Debug Or cmake -S . -B build -DSDL3_DIR="C:/libs/SDL3/cmake" && cmake --build build --config RelWithDebInfo

Tasks

0. Setup environment and build

Build the builds and run them successfully.

1. Profile it!

Profile Debug and Release builds and save it.

2. Data oriented design refactor

Need to refactor every OOP style code like this:

auto newCell = world.create_object();
newCell->add_component<Sprite>(tileset.get_tile(spriteName));
newCell->add_component<Transform2D>(j, i);
newCell->add_component<BackGroundTag>();

With data oriented design SoA approach like that:

struct Tiles
{
    std::vector<Sprite> sprite;
    std::vector<Transform2D> transform;
    // no need to add BackGroundTag, because we don't need it in SoA approach
}

After successful refactor attach profiles after.
