🌍 Better World Border — A Growing, Player-Driven World Limit

A fully dynamic world border system that expands based on player survival, achievements, and progression. Your world now reacts to how well you play.

 



🔷 What Is the World Border?

The World Border is Minecraft’s outer limit that defines where players can exist and build.
In this datapack, it becomes an active gameplay mechanic:

  • Displayed as a blue-red grid;
  • Approaching it causes visual distortion;
  • Outside the border the world does not generate, but in this datapack, stepping beyond the border = instant death.


⚙️ What the Datapack Adds

🛡 Two Game Modes

 

Normal Mode (default):

  • Every 2 days of survival → +1 block to the world border.
  • The longer you survive, the higher the reward. For example: on day 10 the player receives +5 blocks.
  • Rewards are given at 6:00 in-game time.
  • If the player dies, the world border shrinks by 30% (shrink happens at the start of the day).
  • A timer HUD appears at the top of the screen showing time left until the next border change.

Hardcore Mode

  • Rewards are granted every day instead of every two.
  • Scaling is the same: Survive 10 days → +10 blocks.
  • Death ends the run completely unless cheats are used.


🏆 Achievement Rewards

Completing advancements expands the world border:

  • Advancement (frame) → +5 blocks
  • Goal → +50 blocks
  • Challenge → +100 blocks

Achievement rewards are issued at 21:00 in-game time.

 



🔄 Resetting the World Border

Players can restore the default border size by crafting a special item.

Reset Recipe:

1 × Dragon Egg

4 × Phantom Membrane

1 × Ominous Bottle (any level)

1 × Nether Star

1 × Echo Shard

1 × Dragon’s Breath

 

Using the item resets the world border to its original size.
