GPlayEngine

GPlayEngine is a C++ cross-platform game engine for creating 2D/3D games.

GPlayEngine is based on the GamePlay 3D engine v3.0 and principally replace the OpenGL 2.x backend to use the BGFX graphic framework.

Current status

• cmake is used as main build system (qtcreator is also up-to-date)
• bgfx integration is completed and replace opengl.
• bgfx is currently forced to use the opengl driver because engine still use some old glsl shaders. A pass on shaders is planned to use the bgfx shader syntax to be fully compatible with others bgfx backends.
• Engine now use SDL2 by default to manage windows and inputs. Gamepad are not yet implanted.
• Lua is temporarily disabled to speed up the compilation during core dev phase.
• All previous samples and demo are now working with the new renderer.
• A new sample "sample-graphics" is used to test bgfx conversion and new features.
• Only tested on Linux, Windows and Emscripten for now.

Install submodules dependencies

Some thirdparty libraries are registered as submodules, you need to install them before building engine.

git submodule init
git submodule update
