Barrier world
by Dastych
Barrierworld is a Fabric adventure mod that ties the world border to achievements, so each completed advancement widens the playable area.
What it does
Each completed achievement raises the border radius by 50 blocks, measured in Overworld coordinates. The increase is applied to the Overworld, the Nether and the End at the same time, so the three dimensions stay synchronized. The Overworld starts with a base border size, and the Nether border is scaled down by a factor of 8 so that one block in the Nether matches one block of travel in the Overworld. The End is given a border of the same size.
The mod creates a progression system in which players explore farther as they earn more advancements. It suits adventure maps and survival worlds where a border gives structure to exploration, and on a server it applies to every player's world. Barrierworld requires Fabric API. Every player and the server need a copy of the mod. It is published for Fabric only, across three release versions: 1.21.1, 1.21.7 and 26.2, under the MIT License.
