Zeus

Zeus is a multi-purpose JDA command framework designed to make creating bots easier!

Contents

Setup

Setting up Zeus is done via a setup function. Once you have created your discord bot, setup Zeus with the setup() method.

Example:

val jda = JDABuilder.createDefault("token").build()
Zeus.setup(
    api = jda,
    globalMessagePrefix = "!",
    prefixGuildMap = mutableMapOf(
        GUILD_ID_HERE to "."
    ),
    guilds = listOf(
        GUILD_ID_HERE
    )
)

Let's break that down:

  • api: Your JDA instance
  • globalMessagePrefix: For message commands, the prefix that is accepted bot-wide, unless another prefix is set for a guild
  • prefixGuildMap: A map of guild (server) IDs to their own prefix. This will bypassglobalMessagePrefix
  • guilds : A list of guild (server) IDs to set the guild-only commands to. (See Registering Commands)

Commands

Zeus creates and registers commands via objects and annotations (@Annotation). To create a command, you must create an object and inherrit from Command:

import org.bspoones.zeus.command.Command

object MyCommand: Command() {}

Registering commands

Once you have created your command object, head over to your main bot declaration class and add the object to the command registry:

// See setup guide above

CommandRegistry.registerCommands(
    MyCommand::class,
    guildOnly = true
)

Let's break that down:

  • MyCommand::class class of your command, this is a vararg input so you can add as many command objects as you want, seperated by a comma (,)
  • guildOnly default to false, this will decide if all commands you make are guild-only (they will register at a guild level). This is really useful for personal bots or for testing purposes, as commands are registered instantly. Set to false (or don't set it at all) to register all commands globally. This may take a few minutes to register.

Creating a Slash Command

Slash commands are registered via the @SlashCommand annotation. This will register and map the function to a slash command:

object MyCommand: Command() {
    
    @SlashCommand("ping","Send a pong to the chat")
    fun onNameCommand(
        event: SlashCommandInteractionEvent
    ) {
        event.reply("Pong!").queue()
    }
}

As long as you have registered the parent object (in this case MyCommand), any @SlashCommand function will automatically be registered in Zeus' Command Registery.

IMPORTANT: Each Slash command MUST have a name and a description. The name must be lowercase. Here are the following character limits for a Slash Command:

Type Max length
Name 32
Description 100

Creating a Message Command

Message commands are registered via the @MessageCommand annotation. This will register and map the function to custom registry that hooks onto Message Received Events, allowing for more customisation.:

object MyCommand: Command() {
    
    @MessageCommand("ping","Send a pong to the chat")
    fun onNameCommand(
        event: MessageReceivedEvent
    ) {
        event.channel.sendMessage("Pong!").queue()
    }
}

As long as you have registered the parent object (in this case MyCommand), any @MessageCommand function will automatically be registered in Zeus' Command Registery.

IMPORTANT: Each Message Command MUST have a name, and will be the string that is checked whenever a message is sent with a guid's chosen or set prefix

Creating a User Context Command

User Context commands are registered via the @UserContextCommand annotation. This will register and map the function to custom registry that hooks onto User Context Interaction Events.

To use a User Context command, right click any user that shares a server with your bot and select Apps.

object MyCommand: Command() {
    
    @UserContextCommand("ping")
    fun onNameCommand(
        event: UserContextInteractionEvent
    ) {
        event.reply("Pong!").queue()
    }
}

As long as you have registered the parent object (in this case MyCommand), any @UserContextCommand function will automatically be registered in Zeus' Command Registery.

IMPORTANT: Each User Context Command MUST have a name. This will appear in the context menu when you right-click a user >> App

Creating a Message Context Command

Message Context commands are registered via the @MessageContextCommand annotation. This will register and map the function to custom registry that hooks onto Message Context Interaction Events.

To use a Message Context command, right click any message and select Apps.

object MyCommand: Command() {
    
    @MessageContextCommand("ping")
    fun onNameCommand(
        event: MessageContextInteractionEvent
    ) {
        event.reply("Pong!").queue()
    }
}

As long as you have registered the parent object (in this case MyCommand), any @MessageContextCommand function will automatically be registered in Zeus' Command Registery.

IMPORTANT: Each User Context Command MUST have a name. This will appear in the context menu when you right-click a message >> App
