This is a code idea I had to make code that is triggered by mentioning a certain user and warning the triggered user, but it just doesn't work
const Client = require("./Structures/Client.js");
const config = require("./Data/config.json");
const client = new Client();
client.on("messageCreate", message => {
if(message.content == "<@USER2ID>") message.reply("User1#1234 has mentioned User2#1234");
});
client.start(config.token);
You should be using the message.mentions object instead of getting the content of the message. Also is client.start not a function. You should use the client.login function instead. You've also forgot to mention the intents that you want to use. Please take a look at the following example:
const {Client, Intents} = require('discord.js'); // Import the client and intents
const config = require('./Data/config.json'); // Import the config
const client = new Client({
intents: [Intents.FLAGS.GUILD_MESSAGES] // Uses the intent 'GUILD_MESSAGES' to be able to get the messages
}); // Creates the client
client.on('messageCreate', message => { // Creates an event listener
if(message.author.bot || message.channel.type === `DM`) return; // Returns when the author is a bot or if the message is being send in a DM
if(message.mentions.members.get(`0123456789`)){ // If the user with the user id '0123456789' has been mentioned in the message
message.reply(`The user ${message.mentions.members.get(`0123456789`).user.tag} has been mentioned`); // Sends the reply
}
});
client.login(config.token); // Login to the bot
