Staff asked for permanent lore vehicles and emplacements, such as the Zerratoris ruins, that belong to no faction and cost no upkeep. This adds a server owner value.

What changes

  • /vf server, then right-click a vehicle within 60 seconds: converts it to owner server. Admin only. The conversion goes through the normal ownership events with the new staff reason SERVER, so SimpleFactions can veto it or clean up. It also clears the whitelist, group switches and tickets.
  • /vf server list lists live and stored server vehicles. Console can run it too.
  • Use is gated on vf.server.use or vf.admin. Otherwise the new synchronous ServerVehicleUseEvent runs; it is denied by default, and plugins may allow the player (for example SF for a battle side staff assigned). The gate covers interaction, seats, the ticket and direct mount, entity seats and pending creature mounts, and the outside hold. Coupled cars also check their locomotive.
  • Server vehicles cannot be claimed. Whitelist, ticket and group edits are refused. Owner-only actions stay owner-only, and nobody owns a server vehicle.
  • Revert: /vf takeover [character] (reason TAKEOVER), or the staff release button (CLEAR).
  • plugin.yml declares vf.server.use and vf.admin, both default op. vf.admin behaves as before.
  • The owner value displays as "Server".

Testing

  • mvn clean verify: 1997 tests pass and line coverage stays at 100%.
  • Dev server test to follow before merge.

🤖 Generated with Claude Code

Staff can convert a vehicle to the owner value `server` with /vf server
and a right-click. A server vehicle has no player owner, whitelist, group
access or tickets. Players with vf.server.use or vf.admin may use it, and
the new ServerVehicleUseEvent lets other plugins admit more players, such
as a battle side. /vf server list lists them; /vf takeover or the staff
release button reverts the conversion.

Summary

Summary by CodeRabbit

  • New Features
    • Added support for server-owned vehicles, including commands to convert vehicles and list server-owned vehicles with their locations.
    • Added permission-based access and an event that lets plugins approve or deny use of server-owned vehicles.
    • Server-owned vehicles are identified as “Server” and are protected from ownership and access changes, except clearing ownership.
  • Documentation
    • Added guidance on server-owned vehicle commands, access rules and ownership events.

The PR adds server-owned vehicle identification, staff conversion and listing commands, and permission- or event-based use checks. It applies access checks to vehicle interactions, mounts, seat access, ticket access, and outside containers. Conversion clears existing whitelist, group, and ticket settings.

Changes: Server-owned vehicle support

The admin command starts a pending conversion or lists server-owned vehicles and locations. Conversion checks the actor and session, updates ownership, clears access settings, and logs the previous owner.

Server vehicle checks now apply to interactions, mounts, seat menus, ticket seats, and outside containers. Server-owned data does not grant access through existing owner, whitelist, group, or ticket rules. Ownership-menu actions are refused except for clearing ownership.

Merge Risk: Moderate · previous review c810d

Server-owned vehicles can still be entered through the deferred mount-retry path without the new permission or event check. Starting server conversion while a takeover is pending also assigns the takeover owner instead of the server. Both are small fixes and should land before merge.

src/main/java/net/tfminecraft/vehicleframework/managers/VehicleManager.java:1107
Major · Security & Privacy · Quick win

Check server access before the deferred player mount retry.

When a mount is rejected, recoverRejectedMount schedules retryMount. If staff convert the vehicle to a server vehicle before that retry runs, retryMount calls takeSeat without a ServerVehicles.check. A player who lacks vf.server.use and does not pass ServerVehicles.ServerVehicleUseEvent can then be mounted into the server vehicle. The ticket check in allowTicketSeat is a separate, pre-existing gap and is not part of this fix.

Check the current access against fresh before calling takeSeat:

Suggested fix

 		if (rider instanceof Player player && player.isOnline()) {
+			if (!ServerVehicles.check(player, fresh)) return;
 			takeSeat(player, fresh, seat);
 			return;
 		}

…unt retry

Arming /vf server now cancels a pending takeover and the reverse, so the
next click does what the staff member last asked for. A rejected-mount
retry rechecks server-vehicle access before seating the player.

@coderabbitai Both findings are fixed in 3dec5e1:

  • The pending SERVER and TAKEOVER actions now cancel each other (inline thread).
  • The outside-diff finding (VehicleManager.retryMount): the retry now calls ServerVehicles.check(player, fresh) before takeSeat. Covered by the new server-denied case of rejectedMountReloadEitherRetriesTheSavedSeatOrReportsWhyItCannot.

Full verify passes: 1999 tests, 100% line coverage. Please re-review.
