Experienced Worlds
by Drathonix
On a server running Experienced Worlds, the world border grows as players earn advancements, gather blocks and defeat mobs.
What it does
Experienced Worlds is a server-side minigame mod for Fabric and NeoForge. Its world border expands in steps: each time a tracked statistic reaches a power of ten, the border grows by a set amount of blocks, and advancements add to that growth through a multiplier. The growth is shared across the server, so combined player statistics drive it. Required dependencies are Architectury API and Fabric API.
The mod is intended for creating new worlds that are built around the experience of growing outward, rather than adding to an existing one. It can be applied to a new singleplayer or multiplayer world or to an old one, and a world can be started with a seed that only produces a limited set of possible seeds. Most mod mechanics can be configured, and the border shows information about its current state. Released under the MIT License, the source code is open source, and the issue tracker is public.
Key features
Border growth from statistics
Mining blocks and killing mobs count toward statistics, and the border grows each time a statistic reaches a power of ten.
Advancement multiplier
Each advancement earned for the first time raises a multiplier, so later growth from advancements becomes larger.
Border status display
The border shows information about its current state, so players can see how far it has grown.
Configurable mechanics
Most mechanics are configurable, including the growth amount and the advancement multiplier base.
Fairness spawn search
A spawn system looks for fair starting locations and keeps a minimum amount of nearby trees in place.
