Entities in the same space can visit each other directly by calling methods or access attributes. Entities in different spaces can call each over using RPC. A GoWorld server consists of one dispatcher, one or more games and one or more gates. The gates are responsible for handling client connections and receive/send packets from/to clients. The games manages all entities and runs all game logic. The dispatcher is responsible for redirecting packets among games and between games and gates. The game processes are **hot-swappable**. We can swap a game by sending `SIGHUP` to the process and restart the process with **-restore** parameter to bring game back to work but with the latest executable image. This feature enables updating server-side logic or fixing server bugs transparently without significant interference of online players. ## Installing GoWorld GoWorld requries Go 1.10.x to install. ```bash go get -d github.com/xiaonanln/goworld go get -u github.com/golang/dep/cmd/dep cd $GOPATH/src/github.com/xiaonanln/goworld dep ensure go get ./cmd/... ``` **GoWorld uses [Dep](https://github.com/golang/dep) to manage packages.** **For Chinese only:** 中国的朋友可能会碰到网络问题，那么您可以通过点击下载[vendor.tar.gz](http://goworldgs.com/goworld_files/vendor.tar.gz)，并将其解压到goworld根目录下。 Or using [Docker](https://www.docker.com/community-edition): ```bash # debian-jessie + golang + goworld docker run -it xiaonanln/goworld # debian-jessie + golang + goworld + mongodb 3.4 docker run -it xiaonanln/goworld-dev ``` ## Manage GoWorld Servers Use command `goworld` to build, start, stop and reload game servers. **Build Example Chatroom Server:** ```bash $ goworld build examples/chatroom_demo ``` **Start Example Chatroom Server: (dispatcher -> game -> gate)** ```bash $ goworld start examples/chatroom_demo ``` **Stop Game Server (gate -> game -> dispatcher):** ```bash $ goworld stop examples/chatroom_demo ``` **Reload Game Servers:** ```bash $ goworld reload examples/chatroom_demo ``` Reload will reboot game processes with the current executable while preserving all game server states. **However, it does not work on Windows.** **List Server Processes:** ```bash $ goworld status examples/chatroom_demo > 1 dispatcher running, 1/1 gates running, 1/1 games (examples/chatroom_demo) running > 2763 dispatcher /home/ubuntu/go/src/github.com/xiaonanln/goworld/components/dispatcher/dispatcher -dispid 1 > 2770 chatroom_demo /home/ubuntu/go/src/github.com/xiaonanln/goworld/examples/chatroom_demo/chatroom_demo -gid 1 > 2779 gate /home/ubuntu/go/src/github.com/xiaonanln/goworld/components/gate/gate -gid 1 ``` ## Demos ### Chatroom Demo The chatroom demo is a simple implementation of chatroom server and client. It illustrates how GoWorld can also be used for games which don't divide players by spaces. The chatroom demo provides following features: * register & login * send chat message * switch chatrooms **Build Server:** ```bash goworld build examples/chatroom_demo ``` **Run Server:** ```bash goworld start examples/chatroom_demo ``` **Chatroom Demo Client:** Chatroom demo client implements the client-server protocol in Javascript. The client for chatroom demo is hosted at [github.com/xiaonanln/goworld-chatroom-demo-client](https://github.com/xiaonanln/goworld-chatroom-demo-client). The project was created and built in [Cocos Creater 1.5](http://www.cocos2d-x.org/). A running server and client demo can also be found at [http://goworldgs.com/chatclient/](http://goworldgs.com/chatclient/). ### Unity Demo Unity Demo is a simple multiple player monster shooting game to show how spaces and entities of GoWorld can be used to create multiple player online games. * register & login * move players in space * summon monsters * player shoot monsters * monsters attack players Developing features: * Hit effects * Players migrate among multiple spaces * Server side map navigation **Build Server:** ```bash goworld build examples/unity_demo ``` **Run Server:** ```bash goworld start examples/unity_demo ``` **Unity Demo Client:** Unity demo client implements the client-server protocol in C#. The client for unity demo is hosted at [https://github.com/xiaonanln/goworld-unity-demo](https://github.com/xiaonanln/goworld-unity-demo). The project was created and built in [Unity 2017.1](https://unity3d.com/). You can try the demo by downloading [GoWorldUnityDemo.zip](http://goworldgs.com/goworld_files/GoWorldUnityDemo.zip). The demo connects to a goworld server on Amazon EC2 instance.
