GPFlags

GPFlags (Folia port)

A Folia-compatible fork of GPFlags — the GriefPrevention/GriefPrevention3D add-on that lets you set per-claim, per-world and server-wide flags.

This fork keeps the original feature set, but reworks the internals so the plugin runs on Folia's regionized multithreaded architecture. It is designed to pair with GriefPrevention3D, the first GriefPrevention fork with Folia support, and has been tested together with GriefPrevention3D on Folia 26.1.2.

Requirements

What changed from upstream

• Scheduler migration — all BukkitScheduler / BukkitRunnable usage replaced with Folia's GlobalRegionScheduler and per-entity EntityScheduler, wrapped in a small util/FoliaScheduler helper.
• Async teleports — every teleport goes through teleportAsync(), as required for cross-region teleports on Folia.
• Thread safety — shared state moved to concurrent collections (ConcurrentHashMap, ConcurrentLinkedQueue); periodic player tasks collect on the global thread and delegate the actual work to each player's entity scheduler.
• folia-supported: true declared in plugin.yml.
• Built against folia-api 26.1.2.build.8-stable, compiled with Java 25.
• Removed the EliteMobs flag and the bundled legacy bStats metrics class.
• Added a new AllowAnvils flag.

Building
