HRealEngine

HRealEngine is a custom 2D Game Engine built with C++ and OpenGL.

• Start with cloning the repo with git clone --recursive https://github.com/haktan313/HRealEngine

• If you cloned it without the --recursive flag, initialize submodules manually git submodule update --init

• If you make changes to the build files or need to regenerate Visual Studio project files, run scripts/Win-GenProjects.bat this will call premake5 and create the required .sln files.
