## 🎯 **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 — 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** — 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.

---

## ✅ **Prerequisites Check**

**Before you start, make sure you have:**

1. **A computer** (Windows, Mac, or Linux — 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**

---

## 📥 **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! ✅

#### 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! ✅

#### Linux (Ubuntu/Debian):

```bash
sudo apt update
sudo apt install openjdk-21-jdk
java -version
```

You should see: `openjdk version "21.0.x"` ✅

---

### 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 — 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 — we'll use it in Phase 2

---

## 🏗️ **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. Open File Explorer
2. Navigate to a location you'll remember (e.g., `C:\Users\YourName\Documents\`)
3. Right-click → New → Folder
4. Name it: `FirefrostRules`

**Option B: Using Terminal (Mac/Linux):**
```bash
cd ~/Documents
mkdir FirefrostRules
cd FirefrostRules
```

**Write down this path** — you'll need it in a minute.

Example:
- Windows: `C:\Users\Michael\Documents\FirefrostRules`
- Mac: `/Users/michael/Documents/FirefrostRules`
- Linux: `/home/michael/Documents/FirefrostRules`

---

### Step 2.2: Create Folder Structure

Inside `FirefrostRules`, we need to create this structure:

```
FirefrostRules/
├── src/
│   ├── main/
│   │   ├── java/
│   │   │   └── com/
│   │   │       └── firefrostgaming/
│   │   │           └── rules/
│   │   └── resources/
│   │       └── META-INF/
```

**Windows (Command Prompt):**
```cmd
cd C:\Users\YourName\Documents\FirefrostRules
mkdir src\main\java\com\firefrostgaming\rules
mkdir src\main\resources\META-INF
```

**Mac/Linux (Terminal):**
```bash
cd ~/Documents/FirefrostRules
mkdir -p src/main/java/com/firefrostgaming/rules
mkdir -p src/main/resources/META-INF
```

**Why these weird folder names?**
- `src/main/java/` — where Java code lives
- `com/firefrostgaming/rules/` — your "package name" (like an address for your code)
- `src/main/resources/META-INF/` — where mod metadata lives

---

### Step 2.3: Open Project in IntelliJ

1. **In IntelliJ's Welcome Screen:**
   - Click **Open**

2. **Navigate to your project:**
   - Find the `FirefrostRules` folder you just created
   - Select it
   - Click **OK**

3. **Trust the project:**
   - IntelliJ will ask "Trust and Open Project?"
   - Click **Trust Project**

4. **Wait for indexing:**
   - IntelliJ will spend 1-2 minutes "indexing" the project
   - You'll see a progress bar at the bottom
   - Wait for it to finish

---

## 📝 **Phase 3: Adding the Code**

Now we copy/paste all the files into the project.

### Step 3.1: Create Build Files (Root Level)

These files go in the **root** of your project (the `FirefrostRules` folder itself).

#### File 1: `gradle.properties`

1. In IntelliJ, right-click on **FirefrostRules** (the project root in the left panel)
2. Click **New → File**
3. Type: `gradle.properties`
4. Press Enter
5. Copy/paste this content:

```properties
org.gradle.jvmargs=-Xmx3G
org.gradle.daemon=false

# NeoForge 1.21.1 versions
minecraft_version=1.21.1
neo_version=21.1.61

mod_id=firefrostrules
mod_name=Firefrost Rules
mod_version=1.0.0
mod_group_id=com.firefrostgaming.rules
```

6. Press **Ctrl+S** (Windows/Linux) or **Cmd+S** (Mac) to save

---

#### File 2: `build.gradle`

1. Right-click on **FirefrostRules** again
2. Click **New → File**
3. Type: `build.gradle`
4. Press Enter
5. Copy/paste this content:

```gradle
plugins {
    id 'java-library'
    id 'net.neoforged.moddev' version '2.0.74-beta'
}

version = mod_version
group = mod_group_id

repositories {
    mavenCentral()
}

dependencies {
}

neoForge {
    version = neo_version
    
    runs {
        server {
            server()
            systemProperty 'neoforge.enableGameTest', 'true'
            systemProperty 'neoforge.showVulnerabilities', 'true'
        }
    }

    mods {
        "${mod_id}" {
            sourceSet sourceSets.main
        }
    }
}

tasks.withType(JavaCompile).configureEach {
    options.encoding = 'UTF-8'
    options.release.set(21)
}
```

6. Save (Ctrl+S / Cmd+S)

---

#### File 3: `settings.gradle`

1. Right-click on **FirefrostRules** again
2. Click **New → File**
3. Type: `settings.gradle`
4. Press Enter
5. Copy/paste this content:

```gradle
pluginManagement {
    repositories {
        mavenCentral()
        gradlePluginPortal()
        maven { url = 'https://maven.neoforged.net/releases' }
    }
}

rootProject.name = 'firefrostrules'
```

6. Save (Ctrl+S / Cmd+S)

---

### Step 3.2: Create Mod Metadata File

This file goes in `src/main/resources/META-INF/`

1. In IntelliJ's left panel, expand: **src → main → resources → META-INF**
2. Right-click on **META-INF**
3. Click **New → File**
4. Type: `neoforge.mods.toml`
5. Press Enter
6. Copy/paste this content:

```toml
modLoader="javafml"
loaderVersion="[21,)"
license="All Rights Reserved"
issueTrackerURL="https://firefrostgaming.com/support"
showAsResourcePack=false

[[mods]]
modId="firefrostrules"
version="${file.jarVersion}"
displayName="Firefrost Rules"
displayURL="https://firefrostgaming.com"
authors="Firefrost Gaming"
description='''

Built for long-term stability and easy community management.
'''

[[dependencies.firefrostrules]]
modId="neoforge"
type="required"
versionRange="[21.1.61,)"
ordering="NONE"
side="SERVER"

[[dependencies.firefrostrules]]
modId="minecraft"
type="required"
versionRange="[1.21.1,1.22)"
ordering="NONE"
side="SERVER"
```

7. Save (Ctrl+S / Cmd+S)

---

### Step 3.3: Create Java Files

Now we create the 7 Java classes. These all go in:
`src/main/java/com/firefrostgaming/rules/`

**For each file below:**
1. Right-click on the **rules** folder
2. Click **New → Java Class**
3. Type the class name (e.g., `ServerRules`)
4. Press Enter
5. **Delete everything** IntelliJ auto-generated
6. Copy/paste the full code from below

        }

        return rootComponent;
    }

                   .replace("💜", "[Arcane]")
                   .replaceAll("[\\x{1F300}-\\x{1F9FF}]", "");

### Step 3.4: Let IntelliJ Load Gradle

1. **You should see a notification** at the top-right saying "Gradle build scripts found"
2. Click **Load Gradle Project**
3. **Wait** (this takes 5-10 minutes the first time)
   - IntelliJ is downloading NeoForge and all dependencies
   - You'll see a progress bar
   - Be patient — this is normal

4. **When it's done:**
   - The progress bar disappears
   - You see a "Build" tab at the bottom
   - No error messages (if you see errors, see Troubleshooting section)

---

## 🔨 **Phase 4: Building the Mod**

Time to compile the code into a `.jar` file.

### Step 4.1: Open Gradle Panel

1. Look at the **right side** of IntelliJ
2. Click the **Gradle** tab (vertical text on the right edge)
3. The Gradle panel opens
4. Expand: **FirefrostRules → Tasks → build**

### Step 4.2: Run the Build

1. **Double-click** on **build**
2. A "Run" panel opens at the bottom
3. You'll see lots of text scrolling
4. **Wait** (first build takes 3-5 minutes)

**What you're looking for:**
- At the end, you should see: `BUILD SUCCESSFUL`
- Total time will show (e.g., `BUILD SUCCESSFUL in 3m 24s`)

**If you see `BUILD FAILED`:**
- Go to the Troubleshooting section
- Read the error message carefully
- Common issues are listed there

### Step 4.3: Find Your JAR File

1. In IntelliJ's left panel, expand: **build → libs**
2. You should see: `firefrostrules-1.0.0.jar`
3. **Right-click** on it
4. Click **Show in Explorer** (Windows) or **Reveal in Finder** (Mac)
5. This is your mod! 🎉

**File location:**
`FirefrostRules/build/libs/firefrostrules-1.0.0.jar`

---

## 🧪 **Phase 5: Testing Locally**

Before deploying to production, test it locally.

### Option A: Test on Your Pterodactyl Server

If you have a test/dev server:

1. **Upload the JAR:**
   - Go to your Pterodactyl panel
   - Navigate to your test server's **Files**
   - Go to the `mods/` folder
   - Upload `firefrostrules-1.0.0.jar`

2. **Start the server**
3. **Check logs** for: `Firefrost Rules Mod Initialized`
4. **Join the server**
5. **Type:** `/rules`
6. **You should see:** Fallback rules (since Discord isn't configured yet)

### Option B: Skip Local Testing

If you don't have a test server, you can deploy directly to production (we'll configure Discord first).

---

## 🚀 **Phase 6: Deploying to Server**

### Step 6.1: Upload to Production Server

**Via Pterodactyl Panel:**
1. Log into your Pterodactyl panel
2. Select your Minecraft server
3. Go to **Files**
4. Navigate to `mods/` folder
5. Click **Upload**
6. Select `firefrostrules-1.0.0.jar`
7. Wait for upload to complete

**Via SFTP (if you prefer):**
```bash
scp FirefrostRules/build/libs/firefrostrules-1.0.0.jar user@your-server:/path/to/mods/
```

### Step 6.2: Restart Server

1. In Pterodactyl, click **Console**
2. Type: `stop`
3. Wait for server to shut down
4. Click **Start**
5. Watch the console logs

**What to look for:**
- `[firefrostrules]: Firefrost Rules Mod Initialized`
- `[firefrostrules]: Registered /rules command`

**If you see these, the mod loaded! ✅**

---

## 🔧 **Phase 7: Configuring Discord**

The mod is installed, but it doesn't know where to get rules yet.

### Step 7.1: Create Discord Rules Channel

1. **In your Discord server:**
   - Create a channel called `#server-rules` (or use existing)
   - Make it read-only for `@everyone`
   - Only staff can post

2. **Post your rules:**
   - Write your rules in a message
   - You can use Discord markdown:
     - `**Bold**` for headers
     - `- Bullet points`
     - Emojis: 🔥 ❄️ 💜 (these auto-convert)

**Example rules message:**
```
**🔥 FIREFROST GAMING — SERVER RULES**

**Community & Respect**
- Be kind and welcoming to all players
- No harassment, hate speech, or discrimination
- Keep chat appropriate for all ages

**Gameplay**
- No griefing, stealing, or intentional destruction
- No cheating, hacking, or exploiting bugs
- Respect server resources (no lag machines)

**The Foundation**
- Follow staff instructions
- Report issues via Discord ticket system
- Have fun and build something amazing!

Questions? discord.gg/firefrost
```

### Step 7.2: Get Channel ID and Message ID

**Enable Developer Mode:**
1. Discord → User Settings (gear icon)
2. Advanced
3. Enable **Developer Mode**
4. Close settings

**Get Channel ID:**
1. Right-click on `#server-rules` channel
2. Click **Copy Channel ID**
3. Paste somewhere safe (e.g., Notepad)
   - Example: `1260574715546701936`

**Get Message ID:**
1. Right-click on your rules message
2. Click **Copy Message ID**
3. Paste somewhere safe
   - Example: `1234567890123456789`

**Get Bot Token:**
- Use The Arbiter's bot token (you already have this)
- **OR** create a new Discord bot (see "Creating a Discord Bot" below)

### Step 7.3: Edit Config File

1. **On your server, find the config:**
   - Path: `config/firefrostrules-server.toml`
   - (This file is created the first time the server starts with the mod)

2. **Stop your server** (to edit the config)

3. **Edit the file:**

```toml
[discord]
bot_token = "YOUR_ARBITER_BOT_TOKEN_HERE"
channel_id = "1260574715546701936"  # Your channel ID
message_id = "1234567890123456789"  # Your message ID

[performance]
cooldown_seconds = 60
cache_minutes = 30
```

**Replace:**
- `YOUR_ARBITER_BOT_TOKEN_HERE` with your actual bot token
- `1260574715546701936` with your actual channel ID
- `1234567890123456789` with your actual message ID

4. **Save the file**

5. **Start your server**

### Step 7.4: Test It!

1. **Join your Minecraft server**
2. **Type:** `/rules`
3. **You should see:**
   - "Fetching latest rules..." (brief message)
   - Then your rules from Discord, formatted in Fire/Frost/Arcane colors!

**If it works: 🎉 YOU'RE DONE!**

## 🛠️ **Troubleshooting**

### Common Build Errors

#### Error: "Java version mismatch"
**Symptom:** Gradle fails with "Java 21 required"
**Fix:**
1. Verify Java 21 is installed: `java -version`
2. In IntelliJ: File → Project Structure → Project → SDK → Select Java 21
3. Re-run build

#### Error: "Cannot resolve symbol"
**Symptom:** Red underlines in code, imports don't work
**Fix:**
1. File → Invalidate Caches → Invalidate and Restart
2. Wait for IntelliJ to re-index
3. Re-run Gradle: Gradle panel → Reload All Gradle Projects

#### Error: "BUILD FAILED" with cryptic Gradle errors
**Fix:**
1. Check your internet connection (Gradle needs to download dependencies)
2. Delete `.gradle` folder in your project root
3. Re-run build

### Common Runtime Errors

#### "/rules command not found"
**Cause:** Mod didn't load
**Fix:**
1. Check server logs for: `Firefrost Rules Mod Initialized`
2. If not found, mod isn't in `mods/` folder
3. Re-upload the JAR

#### "Invalid Discord Message ID"
**Cause:** Config has wrong message ID format
**Fix:**
1. Message IDs are 17-20 digits
2. Check you copied the full ID (no spaces)
3. Verify with: https://discordlookup.com/message-id

#### "Discord API returned status: 401"
**Cause:** Bot token is invalid
**Fix:**
1. Verify token is correct
2. Regenerate token in Discord Developer Portal
3. Update config

#### "Discord API returned status: 404"
**Cause:** Message or channel doesn't exist / bot can't see it
**Fix:**
1. Verify message ID is correct
2. Verify channel ID is correct
3. Ensure bot is in your Discord server
4. Ensure bot has "Read Message History" permission

#### Rules show as fallback text
**Cause:** Discord fetch failing, using hardcoded fallback
**Fix:**
1. Check server logs for errors
2. Verify bot token, channel ID, message ID
3. Test bot permissions in Discord

## 👩‍💼 **Holly's Editing Guide**

Once everything is working, here's how Holly updates rules:

### How to Edit Rules

1. **Go to Discord `#server-rules` channel**
2. **Find the message** with the rules for the server
3. **Right-click the message**
4. **Click "Edit"**
5. **Make your changes** (use Discord markdown)
6. **Click "Save"**

**That's it!** Next time someone types `/rules` in-game (or after 30 minutes when cache expires), they'll see the new version.

### Discord Formatting Tips

**Headers:**
```
**This is a header**
```

**Bullet points:**
```
- First point
- Second point
```

**Emojis that auto-convert:**
- 🔥 becomes `[Fire]` in orange
- ❄️ becomes `[Frost]` in cyan
- 💜 becomes `[Arcane]` in purple

**Other emojis are removed** (Minecraft can't display them)

### Multi-Server Setup

**If you have multiple servers (Fire Path, Frost Path, etc.):**

1. **Create separate messages** in `#server-rules`
   - Message 1: Fire Path Server Rules
   - Message 2: Frost Path Server Rules
   - Message 3: Creative Server Rules

2. **Each server's config points to its message:**
   - Fire Path config → Message 1's ID
   - Frost Path config → Message 2's ID
   - Creative config → Message 3's ID

3. **Holly can edit each independently**

---

## 📚 **Appendix: Creating a Discord Bot**

If you need a new bot (instead of using The Arbiter):

### Step 1: Create Application

1. Go to: https://discord.com/developers/applications
2. Click **New Application**
3. Name it: `Firefrost Rules Bot`
4. Click **Create**

### Step 2: Create Bot User

1. Click **Bot** in the left sidebar
2. Click **Add Bot** → **Yes, do it!**
3. Under **Token**, click **Reset Token** → **Yes, do it!**
4. **Copy the token** — save it somewhere safe
   - **This is your bot token** (only shown once!)

### Step 3: Set Bot Permissions

1. Still on Bot page
2. Scroll to **Privileged Gateway Intents**
3. **DISABLE** all three (you don't need them)
4. Save Changes

### Step 4: Invite Bot to Server

1. Click **OAuth2** → **URL Generator** in sidebar
2. Under **Scopes**, check: `bot`
3. Under **Bot Permissions**, check: `Read Message History`
4. **Copy the generated URL** at the bottom
5. **Paste in browser** → Select your Discord server → Authorize
6. Bot joins your server!

### Step 5: Use Token in Config

Copy the bot token into `config/firefrostrules-server.toml`:

```toml
bot_token = "YOUR_BOT_TOKEN_HERE"
```
