ProjectionBoundary

ProjectionBoundary is a plugin for Minecraft 1.21 (Paper) that introduces a configurable "world edge" mechanic where the simulation begins to fail. As players approach the configured world limits, they enter increasingly unstable zones — with both gameplay and visual effects — until reaching the final boundary where they are "erased" and teleported away.

What this plugin adds:

A system of three configurable zones near the world border:

Warning Zone: Begins to apply minor status effects (darkness, slowness, weakness), sends rare atmospheric messages, and plays ambient sounds.

Glitch Zone: Applies stronger effects like nausea and blindness, deals periodic magic damage, and creates a sense of visual and audio instability.

Reset Zone: Fully resets the player by clearing their inventory, teleporting them to a random location, and applying confusion effects, simulating memory loss.

Message throttling to prevent chat spam, with cooldown settings in the configuration.

Full configuration support via config

Customize the coordinate thresholds for each zone

Control how frequently players receive messages

Optionally expand or reduce the size of each zone

Use cases:

This plugin is especially well-suited for lore-based, survival, or sci-fi themed servers. It enhances immersion by creating a clear but mysterious boundary that fits into stories involving simulations, corrupted worlds, or artificial projections.
