I was trying to make it so that a user can only react once on a message.
This is my attempt
if(reaction.users.cache.has(user.id)) {
reaction.remove().catch(err => {return;})
}
This always removes the reaction (I understand it's because the user just reacted). I tried checking the reaction emojis like this:
reaction.message.reactions.cache.some(r => r.emoji.name === 'my_emoji')
This always returns true because my bot reacts to it, and other people can also react.
I tried checking the docs but there is nothing like MessageReaction.user that could help.
How can I check if the specific user reacted with a specific emoji?
Try accessing ReactionUserManager along with ReactionEmoji and check if the manager has the id and the current reaction's emoji is your target emoji.
reaction.message.reactions.cache
.filter(r => r.emoji.name === 'my_emoji')
.some(r => r.users.cache.has(user.id));
