BSGL - Buggy-Mushroom's Spore Game Library

A OpenGL port of HGE, running on SDL3.

Building

Third-party dependencies (SDL3, freetype, tinyxml2) are git submodules under 3rd/ and are built automatically by CMake. The one-click scripts initialize the submodules, configure and build:

scripts\build.ps1            # Windows (PowerShell)
scripts/build.sh             # Linux / macOS

Or by hand:

git submodule update --init --recursive
cmake -S . -B build
cmake --build build --config Release

The static library lands in build/lib/<Config>, the SDL3 runtime in build/bin/<Config>.

Using the library

Link against bsgl and define bsgl_main() — the library provides the platform entry point:

#include "bsgl.h"

void bsgl_main() {
    BSGL* bsgl = bsglCreate(BSGL_VERSION);
    bsgl->System_SetStateBool(BSGL_WINDOWED, true);
    if (bsgl->System_Initiate()) {
        bsgl->System_Start();
        bsgl->System_Shutdown();
    }
    bsgl->Release();
}

Tutorials

A tutorial series adapted from the HGE 1.9 tutorials lives in tutorials/. It is built by default; disable it with -DBSGL_BUILD_TUTORIALS=OFF. See tutorials/README.md for details.
