MinecraftConnection

Nuget (with prereleases) Nuget GitHub

日本語版はこちら

MinecraftConnection is a library for sending commands via RCON using C# to help you learn and automate your programming. It can be run on a vanilla server as well as a Spigot server, including plugins. Before running the program, you need to start a Minecraft server that allows RCON connections.

1. Preparation

First, download the Minecraft Server software and run it in any game directory. A server configuration file called server.properties will be created. Specify the password and port number for the RCON connection, and enable the connection.

Configuration example :

rcon.port=25575
rcon.password=minecraft
enable-rcon=true

After adding it save the file and restart the server. Launch Minecraft launcher and log in to the server.

2. Create Project

This library is intended for .NET Standard 2.1 and above. This section describes how to create a .NET 6 console application.

Install MinecraftConnection with the NuGet package manager, or run the following command in the package manager console.

Install-Package MinecraftConnection

Detail：https://www.nuget.org/packages/MinecraftConnection

3. Sample programs

To run the program, start Minecraft Server and Minecraft itself (already logged in to the server). Top-level statements are used here.

3.1 Set the time to 0

using MinecraftConnection;

// IP address or DNS name.
string address = "127.0.0.1";
ushort port = 25575;
string pass = "minecraft";
MinecraftCommands command = new MinecraftCommands(address, port, pass);

command.TimeSet(0);

3.2 Set off fireworks

using MinecraftConnection;
using MinecraftConnection.Entity;

string address = "127.0.0.1";
ushort port = 25575;
string pass = "minecraft";
MinecraftCommands command = new MinecraftCommands(address, port, pass);

// Define the coordinates at which you want to launch
Position pos = new Position(-516, 64, -205);
// Make a fireworks
Fireworks fireworks = new Fireworks()
{
    LifeTime = 30, // Time to explosion
    Type = FireworkType.LargeBall, // Fireworks type
    Colors = FireworkOption.RandomColor(), // Fireworks color (RandomColor() is get random color)
    FadeColors = new List<FireworkColors> { FireworkColors.WHITE }, // after explosion color
};
// Set off fireworks at defined position
command.SetOffFireworks(pos, fireworks);

Result :

Various fireworks can be set off depending on your ingenuity. If you would like to try it, please refer to this page.

3.3 Sorting items in a chest

You can retrieve items in a chest and sort them by ID or by count. The following source code allows you to sort items by name by using the SortById() method on the retrieved item data. The MinecraftConnection.Extends directive declaration is required to use the sorting method.

using MinecraftConnection;
using MinecraftConnection.Extends;

string address = "127.0.0.1";
ushort port = 25575;
string pass = "minecraft";
MinecraftCommands command = new MinecraftCommands(address, port, pass);

// Declare the coordinates of the "Chest block" or "Shulker box".
var pos = new Position(-502, 63, -213);
// Get the items in the chest.
var chestitems = command.GetChestItems(pos);
// Sort the acquired items and overwrite them in the chest again.
command.SetChestItems(pos, chestitems.SortByIdDescending());

Result:

4. Caution

The stop command is disabled due to the risk of stopping the server by RCON remote control. Executing the stop command in SendCommand method will raise an exception.
