About this project
What does [Myarry] Frontier add?
🌎 Frontier
> **Start with almost nothing. Expand your boundaries. Build your world.**
Ever wanted to play Minecraft with a world that **grows alongside your progress**?
**Barrier Expansion** changes the way exploration works by placing you inside a small, restricted area and giving you multiple ways to gradually expand its boundaries. Every expansion opens up more of the world, turning progression into a constant struggle between what you can reach now and what lies beyond your current limits.
Whether you want a challenging progression system, a unique survival experience, or simply a new way to explore Minecraft — **Barrier Expansion gives you the tools to build it.**
✨ Features
📦 3 Ways to Expand
The mod currently provides **three different expansion methods**, each designed to give you control over how your barrier grows.
⌚ Unusual Watches
Use **Unusual Watches** to expand your barrier by a configurable amount.
How much should one Watch expand your world?
**You decide.**
🔮 Expanding Ball
The **Expanding Ball** provides another way to push your boundaries further.
Its expansion amount can be completely customized, allowing you to make it as powerful — or as restrictive — as you want.
🏆 Achievement Expansion
Your achievements can also become a source of expansion.
Configure the mod to automatically expand your barrier whenever an achievement is completed. Different types of achievements can reward you with **different expansion amounts**, allowing more difficult accomplishments to grant greater rewards.
⏳ Automatic Expansion
Don't want to manually expand your barrier?
Enable **Automatic Expansion** and let your world grow with time.
Configure how often the barrier expands and how large each automatic expansion should be. You can create a slow and challenging progression, or let your playable world grow rapidly.
**Your world keeps growing even while you're busy exploring it.**
🔒 Expansion Limit
Looking for an additional challenge?
Frontier includes an optional **Limit System** that restricts how much you can expand your barrier within a certain period of time.
When the limit is reached, further expansions are blocked until the limit resets.
You can configure:
* Maximum expansion limit
* Current limit
* Limit reset time
* Expansion amounts
* And more
This makes it possible to create a progression system where **every expansion counts**.
⚙️ Extremely Configurable
One of the core ideas behind Frontier is **customization**.
The mod is heavily configuration-driven, allowing you to fine-tune almost every aspect of the experience.
Change expansion sizes.
Adjust timers.
Configure achievement rewards.
Set automatic expansion intervals.
Customize the expansion limit.
Enable or disable individual features.
Want a tiny barrier that takes hours to expand?
**You can.**
Want the barrier to grow dramatically every few minutes?
**You can do that too.**
Want to completely disable a mechanic you don't need?
**Absolutely.**
Frontier is built to adapt to **your** progression system rather than forcing you into one.
🖥️ Informative Overlay
Keeping track of your progression is easy with the built-in **Barrier Expansion Overlay**.
The overlay can display useful information such as:
🔹 **Expansion notifications** — know whenever your barrier grows.
🔹 **Limit notifications** — get notified when your expansion limit has been reached.
🔹 **Current limit** — see how much expansion remains available.
🔹 **Maximum limit** — see the maximum amount of expansion available.
🔹 **Limit reset timer** — know exactly when your limit will refresh.
🔹 **Automatic expansion timer** — see when the next automatic expansion will happen.
And if you don't want all that information on your screen...
**Everything can be individually disabled.**
Keep the interface clean and minimal, show only the information you care about, or turn the overlay off completely.
🧩 Create Your Own Experience
Frontier isn't built around a single progression style.
You can combine its mechanics however you want:
**⌚ Use special items** to expand your world.
**🏆 Complete achievements** to earn additional space.
**⏳ Wait for automatic expansions** to happen over time.
**🔒 Manage your expansion limit** to control progression.
Combine everything together or use only the mechanics you need.
🌱 From a Tiny Beginning to a Massive World
At the beginning, your world is small.
Every block beyond your barrier is unreachable. Every expansion gives you access to something new. Every achievement, item, and timer can bring you one step closer to the world beyond.
What starts as a **tiny playable area** can eventually become an enormous world.
**How far will you expand? 🌎**
