Why messageReactionAdd do nothing discord.js

Question

I want to say that I am French, and I apologize for the mistakes.

I try to code a discord bot with node.js, but i have a problem with messageReactionAdd i don\'t now

Answer 1

The message must be cached before it will work. Any messages that come in while your bot is open will automatically get cached, but if it's for a specific older message, you can use:

client.channels.get(CHANNELID).fetchMessage(MESSAGEID);

to cache it. After doing this (each time your script is run) you will receive reaction events for that message.

Answer 2

Events messageReactionAdd and messageReactionRemove working only for cached messages. You need add raw event to your code for trigger any message. https://github.com/AnIdiotsGuide/discordjs-bot-guide/blob/master/coding-guides/raw-events.md

Answer 3

You should listen to the messageReactionAdd event.
Keep also in mind that ReactionEmoji.name is the Unicode for that emoji: you can get the Unicode symbol by writing a backslash before the emoji, like \:joy:. The Unicode for :white_check_mark: is ✅.

This should be your code:

bot.on('messageReactionAdd', (reaction, user) => {
  console.log("first check");
  if (reaction.emoji.name === "✅") {
    console.log("second check");
  }
});

This will work on every cached message, if you want it to work only on a specific message, try using Message.awaitReactions() or Message.createReactionCollector()

Answer 4

You are doing reaction remove and you need to use Unicode emojis - you can find these online and copy them
