What Is McMMOExtras?
McMMOExtras is a companion plugin designed to supercharge your mcMMO server experience. While mcMMO itself brings RPG-like skill progression to Minecraft, McMMOExtras adds a visual layer that keeps players engaged and motivated. The centerpiece is a dynamic experience bar that tracks every mcMMO skill in real time, giving your community a clear, satisfying sense of advancement without cluttering the screen or conflicting with vanilla boss bars.
Core Features
The plugin focuses on delivering one polished feature that changes how players interact with mcMMO’s skill system. Here’s what you get when you install McMMOExtras.
The Dynamic Exp Bar
At the heart of the plugin lies a custom experience bar that uses the boss health bar mechanic. Unlike many HUD additions, this bar is designed to feel native to Minecraft. It supports every existing mcMMO skill—and if a new skill is introduced in a future mcMMO update, the bar will automatically work with it. This forward compatibility means server admins never need to worry about the plugin falling behind.
The bar appears seamlessly above the action bar, showing exactly how much experience you’ve earned toward the next level in your currently active skill. It does not interfere with the Ender Dragon or Wither health bars, because McMMOExtras carefully manages bar priorities. After a configurable amount of time, the bar fades away, keeping the interface clean until you need it again. This subtle touch encourages players to keep grinding, as they can always check their progress with a quick glance.
Permissions and Commands
McMMOExtras keeps things simple on the admin side. Permissions are minimal, making it easy to roll out to your entire player base or restrict to certain ranks.
- mcmmoextras.* — Grants access to every feature of the plugin.
- mcmmoextras.expbar — Allows a player to view the experience bar.
Players can toggle the bar on or off using any of these three commands:
/expbar/mcmmoextras/mcme
This flexibility means even players who prefer a minimal HUD can hide the bar when they want to focus on building or exploring, then bring it back when they’re ready to train skills again.
Requirements and Compatibility
Before you add McMMOExtras to your server, make sure you have the necessary foundation. The plugin depends on a few other pieces to function smoothly.
- mcMMO — The core RPG plugin that handles skill mechanics. You can find it on Bukkit Dev.
- Spigot 1.9 or higher (including all forks like Paper).
- A boss bar API. You have two options:
- barAPI — Available on Bukkit Dev.
- BossBarAPI — An alternative found on SpigotMC.
Installing one of these bar APIs is essential because McMMOExtras hooks into them to render the visual experience bar. Without one, the plugin simply won’t display anything. For those who prefer a streamlined experience, the foxygame.net launcher provides a modern interface where you can install mods like McMMOExtras directly from its built-in menu, saving time and hassle when setting up your client or server pack.
Configuration and Customization
The plugin ships with a straightforward configuration file that lets you adjust how the exp bar behaves. You can set the duration the bar remains visible after gaining experience, fine-tune the display style, and ensure it fits your server’s pace. An example configuration is available on Pastebin, giving you a quick reference to understand all the options. Because the bar relies on the boss bar system, you can also control its color and segments indirectly through the bar API you choose.
Planned Features and Future Updates
The developer has outlined several additions on the roadmap, showing that McMMOExtras is far from a one-off tool. Upcoming features include:
- Permission-based max levels, allowing you to cap skills for different player ranks.
- An auto updater to keep the plugin current without manual file replacement.
- WorldGuard flag integration for specific skills, giving region-based control over training.
These planned features hint at a plugin that will grow alongside your server’s needs, making it a worthwhile long-term investment for any mcMMO-powered world.
Open Source and Community
McMMOExtras is fully open source and hosted on GitHub. You don’t need to decompile anything to see how it works—the source code includes comments and build utilities. If you encounter a bug, have a suggestion, or want to contribute, you can open an issue or submit a pull request directly on the repository. The project welcomes forks, stars, and community involvement. Special thanks go to contributors chasechocolate and SoThatsIt for their early support.
Bringing It All Together
McMMOExtras fills a small but crucial gap in the mcMMO ecosystem. By adding a clean, configurable experience bar, it transforms the way players perceive skill progression. Instead of typing a command or opening a menu to check their stats, they see immediate feedback after every action. That tiny psychological boost can keep a server lively and competitive. With minimal permissions, simple commands, and compatibility with both major bar APIs, the plugin slots into almost any Spigot-based setup without hassle. Whether you run a hardcore survival world or a casual community, McMMOExtras gives your players one more reason to keep mining, fighting, and crafting.
