How to send Embed

[N0m4n904]

Hi, I have this EmbedBuilder:

fun buildNormalEmbed(
    buildData: BuildData?,
    color: Color,
    thumbnail: EmbedBuilder.Thumbnail,
    description: String
){
    val embedBuilder = EmbedBuilder()
    embedBuilder.author?.name = "Build 2"
    embedBuilder.author?.url = "https://halogenos.org"
    embedBuilder.author?.icon = null
    embedBuilder.color = color
    embedBuilder.thumbnail = thumbnail
    embedBuilder.description = description
}

How do I send this now to a specific channel?

Or am I doing it completely wrong? The documentation is not helping here.

With Discord4j I am doing it like this:

fun sendEmbedMessage(embed: EmbedCreateSpec, channelId: String) = reportBotError {
        gateway.getChannelById(Snowflake.of(channelId))
            .ofType(GuildMessageChannel::class.java)
            .flatMap { channel -> channel.createMessage(embed) }
            .subscribe()
    }

But I can't seem to get it to work on Kord.

With kord, you don't have to create builder instances yourself (i.e. calling the EmbedBuilder constructor in your case). Instead we have DSL-like functions.

Here you would call channel.createEmbed which takes a lambda which gets a EmbedBuilder passed as its receiver. So the final code would look something like this:

channel.createEmbed {
    color = TODO()
    description = "..."
    author {
        name = "..."
        url = "..."
        // ...
    }
    thumbnail {
        // ...
    }
    // ...
}

If you want to extract the logic of filling the embed out of the lambda, you can make use of extension functions:

fun EmbedBuilder.buildNormalEmbed(
    color: Color,
    description: String,
    // ...
) {
    this.color = color
    this.description = description
    author {
        // ...
    }
    thumbnail {
        // ...
    }
}

// ...
channel.createEmbed {
    buildNormalEmbed(...)
}

You need a MessageChannel as the channel object in the code above. You could get one by its ID e.g. like this:

val channel = kord.getChannelOf<MessageChannel>(channelId)

thanks, will try that this evening.

Okay, it seems to work, but I have one more question.
I have this Map:

val buildMessages = mutableMapOf<Int, Message>()

on discord4j I can use this code to store a message in that list inside the send function:

fun sendBuildEmbed(buildData: BuildData, embed: EmbedCreateSpec, channelId: String) =
        reportBotError {
            gateway.getChannelById(Snowflake.of(channelId))
                .ofType(GuildMessageChannel::class.java)
                .flatMap { channel -> channel.createMessage(embed) }
                .map { message -> buildMessages[buildData.buildNumber] = message }
                .subscribe()
        }

is it possible to do this in kord?

My function right now looks like this:

suspend fun sendBuildEmbed(buildData: BuildData, embedBuilder: EmbedBuilder, channelId: String) {
        val channel = sharedKord?.getChannelOf<MessageChannel>(Snowflake(channelId))

        channel?.createEmbed {
            embedBuilder
        }
    }

so, am I able to get the message object out of this code to store it inside the map?

createEmbed returns the newly created message, you can simply use it like any function return value
