Moon is a lightweight game server framework based on the actor model. One worker thread can have one or more actors (services), which communicate with each other through message queues. There are many features for game server development.

A fast, scalable, distributed game server engine/framework for C++, including the actor library, and network library, can be used as a real-time multiplayer game engine ( MMO RPG/MOBA ), which supports C#/Lua script/ Unity3d, Cocos2dx and plan to support Unreal. Easy-to-use, interface-oriented design. An extensible plugin framework that makes getting your application running quick and easy. A clean, uncluttered design and stable engine that has been used in several commercial products. A high-performance actor model (by a safe thread pool). Event and attribute-driven, making it clear and easy to maintain your business. Based on standard C++ development, ensuring cross-platform support. An existing C++ and C# game client for rapid development. Cross-platform support.

Ever played a competitive game with a friend in which one of you hosted the server on their own machine? Ever thought that it's unfair that one person's ping is zero and the other one's is 80? This is an open-source program that can emulate constant ping, ping spikes and packet losses. Download, extract wherever you want, launch the executable and read the instructions that are conveniently placed in the main window of the program. This program allows gamers to fake their ping and packet loss. Only games which allow direct IP connections are supported - this program will not emulate the game server and will not advertise itself on any master server of any game. The idea is this: game client -> proxy -> game server Demonstration video: http://youtu.be/2VWNhmfD1Qk
