Server Waypoint Reworked

3.0.4-reworked

Unofficial fork of Server Waypoint 3.0.4 by 2676959 for Forge 1.20.1.

Fixed

• Waypoints stopped syncing after a player died or respawned (for example after kill @a). On Minecraft 1.20.1, respawning replaces the server-side player object, and the player's language was not copied to the new one. Every waypoint chat message sent to that player then crashed with a NullPointerException. The broadcast loop stopped at that player, so no one received the update, and a function such as set_red_spawn stopped after wp remove, so wp add never ran.
  • The player's language is now kept across respawns (ServerPlayer.restoreFrom).
  • A missing language falls back to the server's default instead of crashing.
  • A failure for one player no longer stops the waypoint update from reaching the others; the update packet is also sent before the chat message.

Changed

• Server waypoints show in Xaero's Minimap and World Map for every player, right away. They are added as Xaero server waypoints (Xaero's third-party waypoint API, the same one it uses for Waystones) instead of being copied into a separate waypoint set named after the list.
  • Every list (for example Spawns) appears in the main (default) waypoint tab, so players don't have to switch sets or turn on "render all sets".
  • Players who are online see a new waypoint as soon as it is added, and players who join later get all of them when they connect. The World Map refreshes immediately, even if it is open.
  • They are rebuilt from the server on every sync and never written into the player's own sets, so waypoints a player adds from a shared message are no longer wiped by the next sync.
  • Players can still hide a server waypoint in Xaero's waypoint menu; the choice is remembered.
  • Old copied sets are cleaned up automatically: a set with the same name as a server list is removed only if it contains nothing but that list's waypoints. If it was the selected set, the player is switched back to the default set.
  • New client option xaerosServerWaypoints in config/server_waypoint/client-config.json (default true). Set it to false for the old behaviour, which is also used automatically with Xaero's Minimap versions that don't have the server waypoint API.
  • Built against Xaero's Minimap forge-1.20.1-26.5.0.
• Waypoints are stored per world on dedicated servers. They are saved in <world>/server_waypoint/waypoints/ instead of the shared defaultconfigs/server_waypoint/waypoints/ folder, so each world (map) has its own waypoints. Singleplayer already worked this way.
  • One-time migration: the first world started with this version gets a copy of the old shared waypoints, and the old folder is renamed to waypoints_moved_to_world so other worlds start empty.
  • Each world gets its own id (<world>/server_waypoint/server_id.txt), sent to clients, so a client never shows the previous world's waypoints from its cache.
  • New server option Features.waypointsInWorldFolder in defaultconfigs/server_waypoint/config.json (default true). Set it to false for one shared set of waypoints for every world. Takes effect after a server restart.

No network protocol change: original 3.0.4 clients can still join, but every player needs this version for the Xaero changes.
