xLimbo

A rewrite. Replace the jar and restart: your 1.x config is carried forward, and the old file is kept as config.yml.bak-v1. xLimbo 2 takes over the world 1.x made, builds and all if you kept it saved.

Needs Paper 1.21.11 or newer (or Purpur) and Java 21. 1.x ran on 1.18.2 and newer. Still not for Folia, which can't create worlds.

New

• Send everyone back when the main server is up. With server-check on, xLimbo asks your main server for its status every few seconds, and sends players back the moment it's fully started.
• A paced return. Automatic returns go out a few players a second (queue.per-second), so the main server isn't flattened the moment it's back, and each player sees their place in line on the action bar.
• A player the main server keeps refusing, such as one banned there, is sent back automatically at most three times in five minutes, so they aren't bounced forever.
• The console says when the world is ready, and how long its spawn area took to load.
• A theme at the top of the config: a prefix and four colours xLimbo's messages use. If you never changed a 1.x message, it gets the new look; any you changed are kept.
• An update checker, and bStats anonymous usage statistics. See Privacy for exactly what each sends, and how to turn them off.

Faster arrivals

• Players can't see each other by default (player.hide-others). With hundreds arriving in one spot, everyone tracking everyone else is a limbo's biggest load.
• Players are placed before they're in the world, rather than teleported straight after joining, so each arrival loads one spot, once.
• The land where players arrive is kept loaded, so a whole network landing at once never waits for world generation.
• Arrivals spread up to 64 blocks from the centre by default, rather than 4000. 1.x's spread gave nearly every player fresh land to generate and send. A 1.x config still on 4000 gets 64; one you changed is kept.
• No weather, and no advancement messages.

Everything applies on reload

• /xlimbo reload now applies every setting, /join's aliases included.
• Changing the world's name, floor-block or floor-y rebuilds the world on reload: players are moved out for a moment and put back.
• A config file that isn't valid YAML no longer loses your settings: xLimbo says where the error is and keeps running with the settings it had (or the defaults, at startup) until it's fixed.

Changed

• The floor is purple stained glass by default, easier to see against the void. A 1.x config still on plain glass gets purple; any other block you chose is kept.
• floor-block takes a block as Minecraft names it, such as white_stained_glass; 1.x's GLASS still works.
• With auto-save: false, the world is deleted and made fresh on every startup, so nothing is ever kept on disk.
• With server-check on, players go back as soon as the main server is up, and auto-join isn't used.
• xLimbo marks the worlds it makes, and only ever deletes or rebuilds one it marked. A world of the same name it didn't make is left alone.
• The floor must be a solid block that doesn't fall. It can't be blown up, even with explosions allowed, and it doesn't melt or decay.
• The stray-entity sweep leaves armour stands, item frames, paintings, display and marker entities, and anything tagged xlimbo.keep.
• /join can be turned off.
• Protections that are off no longer listen for events at all.
