Counting game discord js - bots

Question

Hewo everyone. I created my own bot
I have a lot of great things like games etc.
However, I want to do a couting game.
I have a channel called "Counting"
And i want to setup my bot do like:
User 1: 456
User 2: 457
Bot: 458
My question is, How can I make the bot count when no one else is counting? But just once. (Look the example^^)
If you can, can you give me an example code please? Thanks!!

Answer 1

Try this:
const {Client} = require('discord.js')
const client = new Client()
// Stores the current count.
let count = 0
// Stores the timeout used to make the bot count if nobody else counts for a set period of
// time.
let timeout
// Discord.js v12:
// client.on('message', ({channel, content, member}) => {
// Discord.js v13:
client.on('messageCreate', ({channel, content, member}) => {
// Only do this for the counting channel of course
// If you want to simply make this work for all channels called 'counting', you
// could use this line:
// if (client.channels.cache.filter(c => c.name === 'counting').has(channel.id))
if (channel.id === 'counting channel id') {
// You can ignore all bot messages like this
if (member.user.bot) return
// If the message is the current count + 1...
if (Number(content) === count + 1) {
// ...increase the count
count++
// Remove any existing timeout to count
if (timeout) clearTimeout(timeout)
// Add a new timeout
timeout = setTimeout(
// This will make the bot count and log all errors
() => channel.send(++count).catch(console.error),
// after 30 seconds
30000
)
// If the message wasn't sent by the bot...
} else if (member.id !== client.user.id) {
// ...send a message because the person stuffed up the counting (and log all errors)
channel.send(`${member} messed up!`).catch(console.error)
// Reset the count
count = 0
// Reset any existing timeout because the bot has counted so it doesn't need to
// count again
if (timeout) clearTimeout(timeout)
}
}
})
client.login('your token')
Explanation
When a user (that isn't the bot) sends a message in the counting channel, the bot checks if the user is counting correctly (if (Number(content) === count + 1)).
If they are, it increments count, removes the timeout if it exists (if (timeout) clearTimeout(timeout)), and schedules the bot to count after 30 seconds (setTimeout(() => channel.send(++count), 30000)).
If they aren't, the bot sends a message, resets count, and clears the timeout (if it exists).
When the bot sends a message, it won't trigger any of that. When the bot counts, Number(content) === count because it was already incremented.
