So how do you set up this "system"?
- Make sure that the compiler you are using supports at least C++11.
- JSON ayrıştırıcısını (parser) descent.
- Replace old blend_item.h and blend_item.cpp files with new ones, that's all.
- If you want the "hot-reload" (instantly update) function of the JSON file, you can add the cmd_gm.cpp part (recommended).
