Hey dude. I know this comment is a little late, but I was wondering how you can only use a certain command for a specific Discord user ID. For an example, if I wanted to use a meme command that ONLY sends it if I execute the command, and for others it would not respond.

hi! I know im really late since this upload but in the code at 1:48, my code shows an error message when i write the callback. it says message, arguments and text aren't defined. How can I fix that?

[nolanpieters]

I have a problem. Every time I restart my bot it goes back to the default prefix, even though the new prefix is saved in mongoDB

[MewThree]

Hey, I followed along with the entire tutorial, added the missing things from the directories, played around with some things and it's still not working, can you help?

[cyphrix]

So I have 5 different pat gifs but it can only send one when I add the other pat gifs to the coding it sends all 5 at the same time how do I make the pat gifs randomized?

[advertisingboat]

I'm getting an error.
MongoError: topology was destroyed
What does that mean?

[waash]

if i have a help command with the prefix inside, it will not show the new one. how do i fix that : (

[omargreen]

I am working with your code and I have a problem on line 151. Hope you can explain what the error is so that I can find a solution.

Line 151: guildPrefixes[guildId] = result.prefix
Error: Cannot read property 'prefix' or null

Thank you

Hey! Everytime I restart my bot for a new update for example, the custom servre prefix appears to be reset to the global prefix. They are stored in MongoDB.

Your channel is so underrated my guy u need the subs and views great videos

[trikru]

what you can see here in the video seems to be not yet fully developed.
1. as soon as a new server wants to use the bot it switches itself off because it can't find the prefix in the DB
This can be bypassed by

if(result === null) {
return
}

in the for loop.

But
2. now you can't test if you can leave this in the loop because other commands don't work anymore. The commands still use the config for the prefix, but at the same time they use the DB and nothing works anymore. And if I delete what I inserted, the other commands still don't work.

Don't get me wrong, I like your videos a lot but the prefix video doesn't work. Maybe it is because of me, that I did something wrong. I haven't watched the following videos yet, maybe they show how to solve the problem. :)

[boi_tj]

sorry that I'm very late. Just so you know. Yes this works but it doesn't work on the older commands btw.

[bernardopedro]

hey! could you make a video by creating a command in repl.it? I liked your videos but I don’t know how i could put a command there (like the economy command)

[reco]

Thanks for the video, it thought me a lot! Is there a way to not have the bot break when direct messaging it?

[amengaming]

pls can you do vedio how to clear and number like !clear 10
