Slash Command optional parameter [Answered]

Hi, I'm currently working on a poll command where I'm using SelectMenuBuilder and I want for there to be 2 required answers to create the poll. I want the rest of the answers to be optional. Is it possible to make parameters optional or will they always be required?

So far I've only been able to find the [Optional] but it only hides it when using the command, but I'm still required to enter all 8 answers to make the command work...

[SlashCommand("poll", "Create a poll where people can vote")]
        public async Task PollAsync(string Question, string answer1, string answer2, [Optional] string answer3, [Optional] string answer4, 
            [Optional] string answer5, [Optional] string answer6, [Optional] string answer7, [Optional] string answer8)
        {
            var pollBuilder = new SelectMenuBuilder()
                .WithPlaceholder("Select an option")
                .WithCustomId("menu-1")
                .WithMinValues(1)
                .WithMaxValues(1)
                .AddOption(answer1, "answer-1")
                .AddOption(answer2, "answer-2")
                .AddOption(answer3, "answer-3")
                .AddOption(answer4, "answer-4")
                .AddOption(answer5, "answer-5")
                .AddOption(answer6, "answer-6")
                .AddOption(answer7, "answer-7")
                .AddOption(answer8, "answer-8");

            var builder = new ComponentBuilder()
                .WithSelectMenu(pollBuilder);

            await RespondAsync(Question, components: builder.Build());

Wouldn't that just make the unused answers pre-filled? rooThink

pip•10/20/22, 1:42 PM

I think OP's question is more referring to Discord command arguments. To answer your question, is it possible to have 2 required answers, then each subsequent answer optional? The answer is no, all of this information is registered at the Discord level as a part of the command itself. There's no dynamic checks on the Discord level to see if the parameters match your logic

pip•10/20/22, 1:43 PM

Notice how your bot's logic doesn't receive the command until it is actually executed, but Discord knows all of your parameters. This is because you register the parameters of the command initially, and when the command itself is executed then you're able to perform your logic

REAPEROP•10/20/22, 1:51 PM

What I'm looking for is something like this bot. When using the Slash command you can enter different answers but you can leave the unwanted once blank.
@pip If I'm understanding your message correctly then it's not possible for me to do this with my variables as parameters, is that correct? rooThink

pip•10/20/22, 1:54 PM

well isn't that just using MaxValues(2)? in your example

pip•10/20/22, 1:54 PM

that's maybe slightly different from what you described

pip•10/20/22, 1:54 PM

of creating optional parameters after hitting max values

REAPEROP•10/20/22, 1:55 PM

If I use MaxValues(2) then I will allow the user to vote for 2 things in the poll

pip•10/20/22, 1:56 PM

Ok I think i see the problem

pip•10/20/22, 1:56 PM

Yea so you want all parameters optional, but you need at least one parameters for the command to execute

Ppip Yea so you want all parameters optional, but you need at least one parameters fo...

REAPEROP•10/20/22, 1:57 PM

I need the Question and at least 2 answers and then the rest of the answers are optional

pip•10/20/22, 1:59 PM

So just use MinValues(2)? I'm following with you

pip•10/20/22, 1:59 PM

I'm sorry if I'm misunderstanding the point, but I've read everything you've written so far

REAPEROP•10/20/22, 2:00 PM

I might be explaining things a bit weird some times

pip•10/20/22, 2:00 PM

REAPEROP•10/20/22, 2:01 PM

The MinValues forces the user to select at least 2 things to vote for right?

pip•10/20/22, 2:02 PM

allow me to fix your code

REAPEROP•10/20/22, 2:02 PM

I'm perfectly happy with my pollBuilder but I'm having issues with the answer3,4,5,6,7,8 in the parameters if I don't enter something in them when using the slash command

pip•10/20/22, 2:03 PM

public async Task PollAsync(string Question, string answer, [Optional] params string[] options)
{

var pollBuilder = new SelectMenuBuilder()
.WithPlaceholder("Select an option")
.WithCustomId("menu-1")
.WithMinValues(1)
.WithMaxValues(1).AddOption(answer);

foreach(var option in options) { pollBuilder = pollBuilder.AddOption(option); }

var builder = new ComponentBuilder()
.WithSelectMenu(pollBuilder);

await RespondAsync(Question, components: builder.Build());
}

pip•10/20/22, 2:04 PM

this worked a year ago or so

pip•10/20/22, 2:04 PM

i'm not sure if it still does with slash commands

pip•10/20/22, 2:04 PM

so try that out, see if that fixes your problem

pip•10/20/22, 2:05 PM

the other way to do it is with the parameters you have, then just do null checks on each one. if not null, add to selectmenubuilder

REAPEROP•10/20/22, 2:08 PM

REAPEROP•10/20/22, 2:08 PM

It's apparently not happy with the type

pip•10/20/22, 2:11 PM

pip•10/20/22, 2:13 PM

and yea, keep your stuff with answer1 and 2 at the top

REAPEROP•10/20/22, 2:15 PM

This is what I currently have

REAPEROP•10/20/22, 2:15 PM

When I run the bot I get this error?

pip•10/20/22, 2:16 PM

hmm so it doesn't like the optional params

pip•10/20/22, 2:16 PM

let me check the docs rq

REAPEROP•10/20/22, 2:17 PM

Gotta admit sometimes the written commands were easier to make

pip•10/20/22, 2:17 PM

They for sure are much easier. Slash commands are rough to work with

REAPEROP•10/20/22, 2:17 PM

On the other hand they are way smoother to use rooEZ

pip•10/20/22, 2:18 PM

yea better for users

pip•10/20/22, 2:18 PM

pip•10/20/22, 2:18 PM

just use your initial solution

pip•10/20/22, 2:18 PM

and do null checks

REAPEROP•10/20/22, 2:19 PM

REAPEROP•10/20/22, 2:19 PM

Like this?

pip•10/20/22, 2:19 PM

nah remove the params thing I told you to add. use your initial optional stuff.

if(option3 is not null) { pollBuilder = pollBuilder.AddOption(option3, "option3"); }
