Bifrost Usage Guide

Welcome to the Bifrost Usage Guide, a comprehensive resource for integrating the Bifrost framework into your Minecraft Bukkit plugins. Bifrost appears to be a powerful framework that enables developers to send requests to an AI service, generating structured data (e.g., JSON) for dynamic content creation. This guide, inspired by the PersonalThoughts plugin, covers setup, usage, best practices, and theoretical use cases to help you harness Bifrost’s capabilities.

Introduction to Bifrost

Bifrost is a framework designed to bridge Minecraft Bukkit plugins with an AI service, allowing developers to generate dynamic, context-aware content. In the example PersonalThoughts plugin, Bifrost is used to create humorous or event-specific messages for players based on in-game events (e.g., respawning, entering the Nether). The framework handles asynchronous requests to an AI, returning structured data (e.g., JSON) that matches a predefined Kotlin data class.

This guide assumes Bifrost is a custom or third-party library integrated into a Bukkit server environment. While specific details about Bifrost’s internals are not provided, we’ll extrapolate from the code to offer a practical and user-friendly guide.

Prerequisites

Before using Bifrost, ensure you have:

• Java/Kotlin Development Environment: A working setup with Java (or Kotlin) and an IDE like IntelliJ IDEA.

• Bukkit/Spigot Server: A Minecraft server running Bukkit or Spigot (compatible with your plugin’s target version).

• Bifrost Plugin: The Bifrost plugin must be installed on your server

• Basic Kotlin Knowledge: Familiarity with Kotlin data classes, lambdas, and Bukkit event handling (Java developers can adapt with minor changes).

Setting Up Bifrost

Step 1: Add Bifrost Dependency

Ensure the Bifrost library is included in your project. If Bifrost is a plugin, place its JAR in your server’s plugins folder. If it’s a library, add it to your project’s dependencies (e.g., via Maven/Gradle):

// Maven

<repository>
    <id>jitpack.io</id>
    <url>https://jitpack.io</url>
</repository>

<dependency>
    <groupId>com.github.VoxelSquid</groupId>
    <artifactId>bifrost-api</artifactId>
    <version>1.2</version>
    <scope>provided</scope>
</dependency>

Step 2: Initialize Bifrost in Your Plugin

In your plugin’s onEnable method, access the Bifrost instance and verify it’s enabled:

private lateinit var bifrost: Bifrost

override fun onEnable() {
    bifrost = Bifrost.pluginInstance
    if (!bifrost.isEnabled) {
        logger.severe("Bifrost is not enabled or misconfigured. Disabling plugin.")
        server.pluginManager.disablePlugin(this)
        return
    }
    // Proceed with plugin initialization
}

• Bifrost.pluginInstance provides access to the singleton Bifrost instance.

• Check bifrost.isEnabled to ensure Bifrost is operational before proceeding.

Core Concepts

Bifrost Instance

The Bifrost class is the entry point for interacting with the framework. It provides a client object with a sendRequest method to communicate with the AI service. The instance is typically accessed via Bifrost.pluginInstance.

Data Classes for Response Structure

Bifrost expects a Kotlin data class that defines the structure of the AI’s response. For example, in PersonalThoughts, the DynamicPhrases data class specifies four lists of strings:

data class DynamicPhrases(
    val onRespawnPhrases: List<String>,
    val onNetherEnterPhrases: List<String>,
    val onDiamondOreBreakPhrases: List<String>,
    val onCreeperNearbyExplodePhrases: List<String>
)

• The data class must match the JSON structure expected from the AI.

• Use descriptive property names to align with the prompt sent to the AI.

Sending Requests

The bifrost.client.sendRequest method sends a prompt to the AI and handles the response asynchronously. It takes:

• prompt: A string describing the desired output, including the JSON structure and any specific instructions (e.g., tone, content type).

• responseType: The Kotlin data class (e.g., DynamicPhrases::class) to deserialize the AI’s response.

• onSuccess: A lambda to handle the parsed response.

• onFailure: A lambda to handle errors.

Example:

bifrost.client.sendRequest(
    prompt = "Your task is to generate the Minecraft player's thoughts after various events and place them in JSON with specified keys: " +
            "‘onRespawnPhrases’ (array of 15 strings; [try to be humorous]), " +
            "‘onNetherEnterPhrases’ (array of 15 strings), " +
            "‘onDiamondOreBreakPhrases’ (array of 15 strings), " +
            "‘onCreeperNearbyExplodePhrases’ (array of 15 strings [try to be humorously (or sarcastically aggressive) annoyed, joke about creepers (you can do capslock and even swear)])",
    responseType = DynamicPhrases::class,
    onSuccess = { phrases ->
        // 5. Make sure you handle the result. Save it somewhere or.. well.. your choice.
        this.phrases = phrases
    },
    onFailure = { error ->
        println("Error during phrases generation: ${error.message}.")
        error.printStackTrace()
    }
)

• The prompt should clearly define the JSON structure and desired content characteristics.

• The onSuccess lambda receives the deserialized data (e.g., DynamicPhrases).

• The onFailure lambda handles errors, such as network issues or invalid responses.
