v18.4.13: claimed sulfur cubes can no longer be hit, lit or reeled in

GriefPrevention3D v18.4.13

Wiki: https://github.com/castledking/GriefPrevention3D/wiki

Fixes

• Sulfur cubes in claims are protected like other creatures (#12). Minecraft 26.2's sulfur cubes got past claim protection in three ways. All three now need container trust in the cube's claim, which is what hurting any claimed creature already needs:

  • Hits. A cube holding a block takes no damage from a hit. The hit knocks it away instead, and fire aspect lights a TNT cube's fuse. Neither fires a damage event, so creature protection never saw them. On Paper and servers built on it, the hit is now stopped before it lands. That covers knockback, fire aspect and a sword killing an empty cube. Spigot has no event for this, so there a hit cube is still put back where it stood, as before.
  • Arrows and other projectiles. A projectile shot by a player without container trust stops when it hits a claimed cube, so a burning arrow can no longer prime a TNT cube.
  • Fishing rods. Reeling in a claimed cube now takes container trust, as reeling in animals and armor stands already did.

  The protection follows Claims.ProtectCreatures: turn that off and sulfur cubes are no more protected than other creatures. Staff using /ignoreclaims get through as usual.

• New claims reach down to everything built under them. When a claim is created, GriefPrevention looks under it for player-built blocks and storage, and lowers the claim's floor to cover them. If the claim's west or north edge was at a negative coordinate, that search skipped the chunks along that edge. Chests and builds under that part of the claim could end up below the claim's floor, unprotected. Ported from upstream GriefPrevention (#2659). 3D claims are not affected, since they keep the heights they were drawn with.

Upgrade notes

Nothing to migrate and no new options. Sulfur cubes only exist on Minecraft 26.2 and later, so older servers only get the claim depth fix.

The experimental Fabric version in the same jar gains /scrollresize, /trapped, claim alerts and several new protections. They're listed in the Fabric version's changelog on Modrinth.

Both versions still ship in one GriefPrevention3D.jar: 1.8 through the latest release on Spigot, Paper, Purpur and Folia, and 1.21.2 through 1.21.11 and 26.1 through 26.3 on Fabric.
