I am trying to let my bot send a member a dm to a user but I don't know hoe to do it I am very confused..

To make your bot send a direct message to a user on Discord, you can use the following code snippet in your Java Discord bot:

User user = event.getAuthor(); // Get the user to send the message to
user.openPrivateChannel().queue(channel -> {
    channel.sendMessage("Your message here").queue();
});

In this code, event.getAuthor() retrieves the user who sent the original message that triggered the bot. Then, openPrivateChannel() opens a private channel between the bot and the user, and sendMessage() sends the specified message to that channel.

Make sure you have the necessary permissions and intents enabled in your bot's configuration to send direct messages. Also, remember to handle any potential exceptions or errors that may occur during this process.

If you are still facing issues or need further assistance, feel free to ask for help on our Java Q&A Discord server.

            EmbedBuilder eb = new EmbedBuilder();
            User user = event.getUser();
            eb.setTitle("Staff Application accepted");
            eb.setDescription("""
                    Congratulations your staff application on Block Tune has been accepted!!
                    
                    You will receive a DM from a staff recruiter soon and they will be giving you your roles in the server.
                    """);
            eb.setColor(Color.orange);
            eb.setThumbnail("https://cdn.discordapp.com/attachments/1135319391765008495/1262432550241042536/Logo_2.png?ex=669c822e&is=669b30ae&hm=e6c38282ef72e2cd01cc2284d061b61124e986f7b979aadfe7ba3beac1608736&");

openPrivateChannel() only gives u the channel. u still have to send the message over that channel

u know, channel.sendMessage(message) etc

tldr, look at the example the bot gave u

[onyx quartz]

yeah but as what do I define channel?

TextChannel channel = …

or what

[viral bluff]

lookup the method openPrivateChannel(), it tells u the exact type it returns

or use var

or simple chain

openPrivateChannel().sendMessage(...)...queue()

[onyx quartz]

that doesn’t exist

[onyx quartz]

but will try

[viral bluff]

it does

https://ci.dv8tion.net/job/JDA5/javadoc/net/dv8tion/jda/api/entities/PrivateChannel.html

https://i.imgur.com/JdiHmL6.png

its a rest action. so u have to flatmap

author.openPrivateChannel()
  .flatMap(channel -> channel.sendMessage("Hello"))
  .queue();

if that concept is new to u, u should probably step back right now

as JDA is built on top of this

its everywhere

its classic async code

restactions = futures

so they have flatMap as "and then"

and map as "transform"

[onyx quartz]

I am using jda for a long time already just never did a anything with dms

[viral bluff]

and queue at the very end sends out the final action chain

[viral bluff]

okay. then u should be familiar with rest actions 👍

[onyx quartz]

ik

lemme take a look and see if it eorks

works

[viral bluff]

so. openPrivateChannel gives u a RestAction<PrivateChannel>

[onyx quartz]

now it sends the dm to the person who clicked the button the dm

I however wanted it to send the dm to the one who submitted an application so basically the one who interacted with the very first button

any idea how

[viral bluff]

well, open the channel on the right User

can't really help u decipher ur existing code logic without seeing it

[viral bluff]

please just drag drop the code file here

else i can't view it on mobile

[onyx quartz]

code file

[viral bluff]

the java file please

not class 🙂

and then please dont discard the bot who uploads it as gist, thanks

[onyx quartz]

how do i get the java file?

[valid brook]

I uploaded your attachments as Gist.

[onyx quartz]

ohh

makes sense now

[onyx quartz]

sorry 😅

[viral bluff]

could u guide us through the code please. what's going on

[onyx quartz]

basically the first part (MessageReceived event) is just the embed to select either the staff or the freelancer application. then if you click on the button for staff application a modal appears for the user to fill out. after submitting it sends an ebmbed in a set channel for the owner to review. If he clicks on accept application button the I want the bot to send a dm to the user that applied. same thing when the owner clicks the denied button

and I strugle on the dm part

everything else works

[viral bluff]

so u have to memorize the original user throughout ur flow

[versed laurel]

could also use the queue(Consumer). would be a bit more descriptive too, since nothing is actually getting flattened

[viral bluff]

for example by putting his user id into the component id

and then later retrieving the user with that id again

like, ur button id

its freelancer or staff

instead, also add the user id to it

freelancer;123463228484

then, when the button is later clicked, u getId()

split it into the freelancer and the user id

then retrieve that user

[onyx quartz]

but the user id is different every time isn't it? or am I understanding smth wrong

[viral bluff]

jda.retrieveUser(12345..)
 .flatMap(user -> user.openPrivateChannel())
 .flatMap(channel -> channel.sendMessage("huhu"))
 .queue()

[viral bluff]

so? u have the right user id available at the start of ur flow

so that's where u put the user id into ur button ids

then later u retrieve it and act on it

[onyx quartz]

hmm lemme try

[viral bluff]

its the way how discord/jda wants u to transport/memorize data throughout the async flow

u put it into the component ids

like, suppose u want to make a dialog to create a button that will say hello to a user u selected in the dialog

then that button somehow needs to memorize which user its tied to

i. e. the dynamic information from the dialog that spawned it

so that later, when someone clicks the button a year later, ur code still knows who this button was supposed to say hello to

so instead of the button having just an id of "hello_button", u would also attach the user id to it

"hello_button;1428528472"

then, when the button is clicked, u can extract the information back from there and use it

[onyx quartz]

why jda. tho?

[viral bluff]

theres plenty of options to retrieve an user. that's just one of them

[onyx quartz]

somehow I am not capable of doing what you told me

could you maybe give me a step by step guide ?

[viral bluff]

which part of what i said is unclear to u?

where in ur code is the user u want to dm to?

and where exactly is the point in ur code where u want to do the dm thing?

what's the flow like between those two points

[onyx quartz]

how and where I get the user id from and where in my code i put it how

[versed laurel]

youll need to store the ID of the user who created the app somewhere

when someone submits an app, it sounds like your code creates a message with a button. you could have a Map, which you would store the ID of the message with the button (as the key) and the ID of the user who submitted the app (as a value)

[onyx quartz]

yeah but how do I put that in my code

[versed laurel]

you'd declare the map as a field variable. then, where you handle the app submitting code (in onModalInteraction), you would grab the ID of the button & the ID of the user who created the event

[viral bluff]

first of all, step back and tell me where in ur code u have the user u want to send a dm to

write a System.out.println("Hello ..."); with the user u want to later DM to

where in ur code do u have hands on the user?

u cant continue with the rest if u dont understand where in ur code the user u want to work with is located at...

so lets do that first

[onyx quartz]

atm I have the hand on the user no where

[onyx quartz]

well normally I would get the user from the very top where i made the buttons in the onMessageReveived EVent

[viral bluff]

please describe in words which user u want to DM

so that we can spot the point in ur flow where this user would be available

since u seem to not know

[onyx quartz]

Okay I shared my code with you right?

so in the very first lines us the onMessageReceivedEvent where I have made two buttons for two applications

i want to dm the user that interacts with the button

[viral bluff]

so the user who clicks the freelancer/staff app buttons should be DMed?

or the user who send the +setup message?

[onyx quartz]

yes

[onyx quartz]

no that is just to send the whole embed with both buttons

[viral bluff]

so what happens when someone clicks the button? a modal pops up and then eventually the user clicks on submit on the modal, right?

and thats when u want to send the DM?

or already when the staff/freelancer button is clicked?

oh, the modal creates even more, right?

[onyx quartz]

when a user clicks the button staff/freelancer which opens a modal. After submitting a modal it sends another embed in a different channel with the values of the modal. If the another person clicks on the button attechted to the embed send by the modal I want the bot to send a dm to the user that clicked the staff/freelancer button

[viral bluff]

ah i see

okay. so heres the thing

when the freelancer/staff button is clicked, u have the member u want to DM here:

https://i.imgur.com/YLWfVqE.png

notice the "when the freelancer/staff button is clicked"

not ur other button

but thats the user u want to DM

[onyx quartz]

yes

[viral bluff]

also, u have him in the modal

since he is the one submitting the modal

so here:

https://i.imgur.com/PjEkPuv.png

thats also ur DM-user

[onyx quartz]

okay understood

[viral bluff]

the flow from here is that this piece of code sends some messages with button in that other channel u mentioned

the accept-button

the button is then clicked by someone else, like a moderator or so

[onyx quartz]

correct

[viral bluff]

and the flow continues here:

https://i.imgur.com/t0Rz0UV.png

i.e. in ur button handler again

but this time in the other if block

in ur button handler, u have the possibility to access the so called component ID of the button

ur doing that at the very top already

String butttonId = event.getButton().getId();

now, this ID can be choosen freely by u

which u did here for example:

https://i.imgur.com/v1fNYsF.png

so nothing would hold u back from storing actual information in there

other than just the name of ur button

such as for example the id of the user u want to DM

https://i.imgur.com/ddugrTF.png

Button.success("accept;" + member.getId(), "Accept Application")...

[onyx quartz]

ohh like that that makes sense

[viral bluff]

now ur button id is sth like accept;1291249129412393 in practice

[onyx quartz]

okay and then I retrieve that id how?

[viral bluff]

so when its later clicked and u end up here: https://i.imgur.com/i8Fgctv.png

u can now extract that id

String userId = buttonId.split(";")[1];

after extraction, u need to somehow retrieve a proper user object from that id

like a User or Member

for that, u can write jda.retrieveUserById(userId)

[onyx quartz]

well jda. doesn’t work I tried it like that already

[viral bluff]

it does

u can get hands on JDA everywhere

event.getJda()

for example

event.getJda().retrieveUserById(userId)

[onyx quartz]

oh right

[viral bluff]

u could also retrieve a member via the guild

doesnt matter

server.retrieveMemberById(userId)

but if u go with former, u can also message users who arent in ur guild anymore

[onyx quartz]

okay I think I understand now

[viral bluff]

now, this is a rest action. so u have the user now in ur async "future"

RestAction<User>

and can flatMap from there

event.getJda().retrieveUserById(userId)
  .flatMap(User::openPrivateChannel)
  .flatMap(channel -> channel.sendMessage("huhu"))
  .queue();

[onyx quartz]

why twice : between User::openPrivateChannel?

[viral bluff]

its called a method reference

its the same as writing user -> user.openPrivateChannel()

[onyx quartz]

ahh

I see I still have a bit to learn😅

but thank you I will try when I get home

[viral bluff]
