Another Fairygui runtime basically copied from https://github.com/u0u0/Cocos2d-Lua-Community but compatible with our cocos2d-x branch. It should also work with other v3 branches with minor changes.

Install in cocos2d-x project:

git submodule add https://github.com/WuJiayiSH/FairyGUI-cocos2dx-runtime.git frameworks\FairyGUI-cocos2dx-runtime

Update your CMakeLists.txt:

add_subdirectory(${CMAKE_CURRENT_SOURCE_DIR}/frameworks/FairyGUI-cocos2dx-runtime)
target_link_libraries(${APP_NAME} fairygui_runtime)
target_include_directories(${APP_NAME} PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/frameworks/FairyGUI-cocos2dx-runtime)

Register lua bindings in AppDelegate.cpp(Lua specific):

#include "lua_fairygui.hpp"
...
register_fairygui_manual(luaState);

You're good to go but might need this line to get UI music work(Lua specific):

fairygui.UIConfig.onMusicCallback = function(path)
    audio.playSound(path)
end
