- Compatible API Versions
- 1.0.0-1.0.12
Broke on Nukkit API Update 1.0.13 and I dont have the sourcecode anymore
Some plugins need some data from another Servers. Bukkit has an API to get the data. Nukkit does not.
Thats why I made ServerCommunicator.
It gets this data from another Nukkit Server. The called server have to install this Plugin.
How to use as consumer:
Download the file and put it in your plugin folder. Thats it
How to use as developer:
First of all, you should add ServerCommunicator to your dependencies in your plugin.yml
To build a connection to another Server, create a NukkitConnection:
To get the data, use the following API:
I would prefer to check if a connection is possible:

Java:
NukkitConnection example = new NukkitConnection("127.0.0.1", 19132);
NukkitConnection example2 = new NukkitConnection();
example2.setAddress("127.0.0.1");
example2.setPort(19132);
Java:
NukkitConnection con = new NukkitConnection("127.0.0.1", 19132);
int onlineplayers = con.getOnlinePlayers();
int maxplayers = con.getMaxPlayers();
String motd = con.getMotd();
Java:
NukkitConnection con = new NukkitConnection("127.0.0.1", 19132);
if(con.canConnect()){
//do code
} else Server.getInstance().getLogger().critical("Connection to " + con.address + ":" + con.port + " not possible");But the servers where you want to get the data from still need to install this plugin
