From aaffffe987f34a5e1ccc51aa6d1827a12519f936 Mon Sep 17 00:00:00 2001 From: "Claude (Chronicler #46)" Date: Sun, 29 Mar 2026 03:57:39 +0000 Subject: [PATCH] docs: complete zero-to-hero guide for Firefrost Rules mod WHAT WAS DONE: Created comprehensive beginner's tutorial for building the Firefrost Rules mod from absolute zero experience. Assumes no prior Java or Minecraft modding knowledge. WHY: Michael requested "sub zero to hero" level guide - he has no prior Java development experience and needs to learn everything from scratch. Guide covers (1,700+ lines): - What Java/JDK/IDE/Gradle/NeoForge are (plain English) - Installing Java 21 JDK (Windows/Mac/Linux) - Installing IntelliJ IDEA Community Edition - Creating project structure from scratch - Understanding folder organization (src/main/java, package names) - Copy/paste all 10 files (3 build + 1 metadata + 7 Java) - Running Gradle build (first-time setup) - Finding the compiled JAR - Deploying to Pterodactyl server - Configuring Discord (channel ID, message ID, bot token) - Testing the /rules command - Troubleshooting common errors (build failures, runtime issues) - Holly's editing workflow - Creating a Discord bot (appendix) Accessibility features: - Plain English explanations (no jargon without definition) - Step-by-step with screenshots described - Common errors with exact fixes - Analogies for complex concepts - Checkpoints after each phase FILES CHANGED: - docs/guides/firefrost-rules-mod-beginner-guide.md (new, 1,741 lines) NEXT STEP: Michael follows guide on desktop, builds first Java mod from zero.

[Holly's Editing Guide](#hollys-editing-guide) + +--- + +## 🎯 **What You're Building** + +You're creating a **Minecraft server mod** that: +- Adds a `/rules` command players can type in-game +- Fetches the rules from a Discord message (so Holly can edit them easily) +- Displays the rules in chat with pretty Fire/Frost/Arcane colors +- Works on all your Minecraft 1.21.1 NeoForge servers + +**Why this is cool:** +- Holly never needs to SSH into a server or edit files +- She just right-clicks a Discord message, edits it, and saves +- Next time someone types `/rules` in-game, they see the updated version +- Zero server downtime, zero technical knowledge needed + +--- + +## 🧠 **Understanding the Basics** + +Before we start, let's demystify what everything is: + +### What is Java? +**Java** is a programming language. Minecraft is written in Java, so mods are also written in Java. + +Think of it like: if Minecraft speaks Spanish, mods need to speak Spanish too. Java is that language. + +### What is a JDK? +**JDK** = Java Development Kit. It's the software that lets you write and compile Java code. + +**Analogy:** If Java is Spanish, the JDK is the dictionary and grammar book you need to write in Spanish. + +**You need:** Java 21 JDK (Minecraft 1.21.1 requires this specific version) + +### What is an IDE? +**IDE** = Integrated Development Environment. It's a fancy text editor made for writing code. + +**Analogy:** You *could* write code in Notepad, but an IDE is like Microsoft Word for programmers β€” it highlights mistakes, auto-completes words, and makes everything easier. + +**We're using:** IntelliJ IDEA Community Edition (free, industry standard for Minecraft mods) + +### What is Gradle? +**Gradle** is a build tool. It takes your Java code (which humans can read) and compiles it into a `.jar` file (which Minecraft can run). + +**Analogy:** You write a recipe (Java code). Gradle bakes it into a cake (the mod file). + +**You don't need to install Gradle** β€” it comes bundled with your project. + +### What is NeoForge? +**NeoForge** is the mod loader for Minecraft 1.21+. It's the framework that lets mods talk to Minecraft. + +**Analogy:** Minecraft is a restaurant kitchen. NeoForge is the system that lets new cooks (mods) work in that kitchen without breaking everything. + +### What is a .jar file? +**JAR** = Java Archive. It's a zip file containing compiled Java code. + +When you "build" the mod, Gradle creates a `.jar` file. You put that `.jar` file in your server's `mods/` folder, and Minecraft loads it. + +--- + +## βœ… **Prerequisites Check** + +**Before you start, make sure you have:** + +1. **A computer** (Windows, Mac, or Linux β€” all work) +2. **Administrator access** (you'll need to install software) +3. **Internet connection** (to download Java, IntelliJ, etc.) +4. **At least 4GB free disk space** (for tools + project) +5. **A Minecraft 1.21.1 NeoForge server** (running and accessible) +6. **Discord bot token** (from The Arbiter, or create a new bot) +7. **Patience** (first time takes longer, but you'll learn!) + +**Time you'll need:** +- Software installation: 30-60 minutes +- Project setup: 15-30 minutes +- Building the mod: 10-15 minutes +- Testing: 15-30 minutes +- **Total: 2-4 hours** + +--- + +## πŸ“₯ **Phase 1: Installing Software** + +We need to install 2 things: Java 21 and IntelliJ IDEA. + +### Step 1.1: Install Java 21 JDK + +#### Windows: + +1. **Download Java 21:** + - Go to: https://adoptium.net/temurin/releases/ + - Select **Version: 21** + - Select **Operating System: Windows** + - Click **Download .msi** (not .zip) + +2. **Install:** + - Run the downloaded `.msi` file + - Click "Next" through the installer + - **IMPORTANT:** Check the box that says "Set JAVA_HOME variable" + - **IMPORTANT:** Check the box that says "Add to PATH" + - Click "Install" + - Wait for it to finish + +3. **Verify it worked:** + - Open Command Prompt (press Win+R, type `cmd`, press Enter) + - Type: `java -version` + - You should see something like: `openjdk version "21.0.x"` + - If you see this, Java is installed! βœ… + +#### Mac: + +1. **Download Java 21:** + - Go to: https://adoptium.net/temurin/releases/ + - Select **Version: 21** + - Select **Operating System: macOS** + - Click **Download .pkg** + +2. **Install:** + - Run the downloaded `.pkg` file + - Follow the installer prompts + - Enter your password when asked + +3. **Verify it worked:** + - Open Terminal (Cmd+Space, type "Terminal", press Enter) + - Type: `java -version` + - You should see: `openjdk version "21.0.x"` + - If you see this, Java is installed! βœ… + +#### Linux (Ubuntu/Debian): + +```bash +sudo apt update +sudo apt install openjdk-21-jdk +java -version +``` + +You should see: `openjdk version "21.0.x"` βœ… + +--- + +### Step 1.2: Install IntelliJ IDEA Community Edition + +#### Windows: + +1. **Download IntelliJ:** + - Go to: https://www.jetbrains.com/idea/download/ + - Click **Download** under "Community Edition" (the free one) + +2. **Install:** + - Run the downloaded `.exe` file + - Click "Next" through the installer + - **IMPORTANT:** Check these boxes: + - "Create Desktop Shortcut" + - "Add 'Open Folder as Project'" + - "Add launchers dir to PATH" + - Click "Install" + - Restart your computer when it finishes + +#### Mac: + +1. **Download IntelliJ:** + - Go to: https://www.jetbrains.com/idea/download/ + - Click **Download** under "Community Edition" + +2. **Install:** + - Open the downloaded `.dmg` file + - Drag "IntelliJ IDEA CE" to your Applications folder + - Open IntelliJ from Applications + +#### Linux: + +**Option A: Snap (easiest):** +```bash +sudo snap install intellij-idea-community --classic +``` + +**Option B: Manual:** +- Download from: https://www.jetbrains.com/idea/download/#section=linux +- Extract the `.tar.gz` file +- Run `bin/idea.sh` + +--- + +### Step 1.3: First-Time IntelliJ Setup + +1. **Open IntelliJ IDEA** + - First time you open it, it'll ask some questions + +2. **Theme:** + - Choose Dark or Light theme (personal preference) + - Click "Next" + +3. **Plugins:** + - It'll suggest plugins β€” click "Skip Remaining and Set Defaults" + - (We don't need extra plugins for this project) + +4. **Welcome Screen:** + - You should see "Welcome to IntelliJ IDEA" + - Leave this open β€” we'll use it in Phase 2 + +--- + +## πŸ—οΈ **Phase 2: Creating the Project** + +Now we create the folder structure for your mod. + +### Step 2.1: Create Project Directory + +**Option A: Using File Explorer (Windows):** +1.
