Start minecraft server via discord bot

mcserver-discord-bot.js

var spawn = require('child_process').spawn;
var discord = require("discord.js");

var bot = new discord.Client();
var mcserver;

// The start.bat has to include a 'cd "C:/Users/_____/Desktop/Server/"' command (See start.bat for more details)
var MC_SERVER_START_SCRIPT = "C:/Users/_____/Desktop/Server/start.bat";

bot.on("message", function(message){
  if (message.content == "start") {

    // Only start if not running
    if (mcserver == null) {
      bot.sendMessage(message, "Starting server...");

      // Start the server
      mcserver = spawn(MC_SERVER_START_SCRIPT);

      mcserver.stdout.on('data', (data) => {
        console.log("stdout: " + data);
        // Not everything is send (because i think there is a send limit per time)
        // bot.sendMessage(message, "stdout: " + data);
      });

      mcserver.stderr.on('data', (data) => {
        console.log("stderr: " + data);
        bot.sendMessage(message, "stdout: " + data);
      });

      mcserver.on('close', (code) => {
        console.log("child process exited with code " + code);
        bot.sendMessage(message, "child process exited with code " + code);
      });

    }

  } else if (message.content == "stop") {

    // Only stop if running
    if (message.content == "start") {
      bot.sendMessage(message, "Stopping server...");

      // Stop the server
      mcserver.kill();

      mcserver = null;
    }
  }
});

bot.login("email", "pass")

@JonnyKartofa I know this is late, but show me your code and I might be able to help

sorry I can't help any more than that

Made a GitHub repository that showed how to do this

https://github.com/Whitelisted1/startProgram/tree/main

Changed some things to make it (hopefully) better! Some stuff was out-of-date but should work correctly now.

var kill  = require('tree-kill');
var spawn = require('child_process').spawn;
var discord = require("discord.js");

var bot = new discord.Client({ intents: ["GUILDS","GUILD_MESSAGES"]});
var mcserver;
var lastMsgTime = 0;

// IMPORTANT: Change the path below to the start.sh file.
// After that, you're done editing this script.
var MC_SERVER_START_SCRIPT = "C:/path/to/start.bat";

bot.on("ready", () =>{
  console.log('Bot online!');
});

bot.on("messageCreate", function(message){

  var msgContent = message.content.toLowerCase();

  if (msgContent == "start") {

    console.log('Attempting to start server.');
    // Only start if not running
    if (mcserver == null) {
      
      if ((bot.uptime - lastMsgTime) < 0)
      {
        console.log("Potential command spamming by " + message.author.username);
        message.channel.send("Last command was less than 60 seconds ago. Try again in a minute, " + message.author.username + ".");
      }
      else
      {
        lastMsgTime = bot.uptime;

        message.channel.send("Starting Minecraft server. This will take a minute or so.");

        // Start the server
        mcserver = spawn(MC_SERVER_START_SCRIPT);

        mcserver.stdout.on('data', function (data) {
            console.log("stdout: " + data);
            
            message.channel.send("stdout: " + data);

            if (data.includes("Closing Server")) {
              kill(mcserver.pid);
              mcserver = null;
            }
          });
        

        mcserver.on('close', function (code) {
            console.log("child process exited with code " + code);
            message.channel.send("Minecraft server has been closed. (Code: " + code + ")");

            // Stop the server
            if (mcserver != null) {
              kill(mcserver.pid);
            }

            mcserver = null;
          });
      }
    }
    else
    {
      message.channel.send("Minecraft server is already running.");
    }

  } else if (msgContent == "stop") {

    
    if ((bot.uptime - lastMsgTime) < 0)
    {
      console.log("Potential command spamming by " + message.author.username);
      message.channel.send("Last command was less than 60 seconds ago. Try again in a minute, " + message.author.username + ".");
    }
    else
    {
      lastMsgTime = bot.uptime;

      // Only stop if running
      if (mcserver != null) {
        message.channel.send("Force-stopping Minecraft server...");

        // Stop the server
        kill(mcserver.pid);

        mcserver = null;
      }
    }
  }
});

bot.login("BOT_TOKEN");

@Stonley890 I tried your code and got the following error

Bot online!
Attempting to start server.
node:events:368
throw er; // Unhandled 'error' event
^

I used your code but put in the .bat location ("C:\Users\Hasnain Javed\Documents\MCServerDiscordBot-master\Servers\ServerB\Start.bat") and the Bot Token.

Can you help?

(I'm on Windows if that means anything)

@TeddySenpai I've reworked the script in this repository: Stonley890/mc-console-bot
Try using this one.

@Stonley890 or @Whitelisted1 is the code currently up to date because i tried it a few months back and couldn't get it to work
