Link the google's protocol bufffers library as the third party in Unreal Engine 4.

Usage

1. Import or copy the folder 'libprotobuf' into <your project>/ThirdParty/libprotobuf.
2. Add the libprotobuf as a module into <your project>.Build.cs

• PrivateDependencyModuleNames.AddRange(new string[] { "CoreUObject", "Engine", "libprotobuf" });

1. Generate two code files (header & source, ex: Message.pb.h & Message.pb.cc) of the protocal by protoc for cpp. (Ref: Google's Protocol Buffers)
2. Put them into the source directory (Private or Public) of your project.
3. Regenerate the code file for Unreal Engine 4 by regenerateforue4.py.
   • python regenerateforue4.py 'the header file'
   • ex: python regenerateforue4.py Message.pb.h
   • You should get this information: Success to regenerate the code for UE4
4. Include and use the header file(ex: Message.pb.h) in your .cpp file.
5. That's all.
