Nucleus released this version on Feb 2, 2017

3.2 MB

Nucleus 0.21.0 is available for Sponge API 5.1 and is compatible with current builds for Sponge API 6-SNAPSHOT.

This build is for Minecraft 1.11.2/Sponge API 6. Use this version for Minecraft 1.10.2/Sponge API 5.1

Documentation can be found at http://nucleuspowered.org/docs (command and permission references should already be up to date). Developer documentation is available at http://jd.nucleuspowered.org.

Note that there are now two builds for Nucleus. Use S5.1 for 1.10.2 servers, S6 for 1.11.2 servers.

NucleusMixins, an optional companion plugin for Nucleus, is available for Sponge API 5 (Minecraft 1.10.2) servers, and will provide a workaround for /invsee not working as intended, and enhanced world generation by hooking into Minecraft internals (known as “NMS” to some players). It is entirely optional, and may not work on heavily modded servers. If you wish to turn off either the /invsee or enhanced world generation mixins, you can do so by setting the relavent option in mixins.conf.

I’ve tightened an item ID check, so some items that you may have used in the shop module, for example, may no longer work and need to be redefined. Indeed, they may not be, but this is to ensure consistency in the future. Sorry for any inconvenience.

Developers: The API now has its own jar file

In order to combat problems with dependencies, you can now include a smaller API jar via Gradle!

Repository: ‘http://repo.drnaylor.co.uk/artifactory/list/minecraft’. Dependency (for this version): ‘io.github.nucleuspowered:nucleus-api:0.21.0-S5.1-PR2’

In future, the API version will match the format Nucleus Version-S{Sponge API Version}-{Modifiers}. I’ll try to remember to put the version numbers in release notes.

Home and Warp APIs

Nucleus has undergone a rebuild of the Home and Warp systems to allow for integration with other plugins. The NucleusHomeService and NucleusWarpService services, and the NucleusHomeEvent and NucleusWarpEvent events. This is in additon to what is already available, and is slowly being documented.

The Home and Warp APIs will be considered stable for Nucleus 0.x & 1.x once 0.21.x is released.

This will initially integrate with GriefPrevention, but any plugin is welcome to use these events.

List has been turbocharged

List was good. List worked. List wasn’t great. Now it is.

  • Groups can have a weight, determining which one is used as a display group if a player has more than one group. This is controlled by permission options on the group: nucleus.list.weight - apply this to GROUPS not users.
  • Groups can be given an alias, and multiple groups can have the same alias. This can be defined in main.conf, playerinfo.list.list-grouping-by-permission.group-aliases.
  • The group ordering can be defined in main.conf, playerinfo.list.list-grouping-by-permission.group-order. Note that you must keep the [], and it’s a comma separated list, where the names are enclosed in " characters.
  • There is an option to only display a group if it has an explicit alias, else collapse into the default group.

More flags for the /world create command

To recap, the available flags are now:

  • -d/–dimension : the dimension to use as a base world type. Defaults to the overworld.
  • -g/–generator : the world generator to use. Defaults to the default generator.
  • -m/–modifier : a world generator modifier to use. Can be specified multiple times for multiple modifiers.
  • –di/–difficulty : the initial world difficulty. Defaults to normal.
  • –gm/–gamemode : the default game mode for players in the world. Defaults to survival.
  • -s/–seed : The seed to use to generate the world. If not specified, a random seed will be used.
  • -i: Indicates that this world might exist and can be imported.
  • -n/–nostructures: If specified, will not generate structures in the world.
  • -l/–loadonstartup <true|false>: If false, the world will not be loaded on startup. Defaults to true.
  • -k/–keepspawnloaded <true|false>: If false, the spawn will not be kept loaded. Defaults to true.
  • -c/–allowcommands <true|false>: If false, commands will not be allowed on the world. Defaults to true.
  • -b/–bonuschest <true|false>: If false, the bonus chests will not be generated. Defaults to true.

More text tokens

You may now use {{ipaddress}} to get the player’s IP address, and {{uniquevisitor}} to get an estimated visitor count, in places such as the MOTD and info files. If you think the unique visitor count seems to be off, run /nucleus debug refreshuniquevisitors. This will update the count in the background.

Sponge Timings support

Now, if you use /sponge timings, Nucleus will appear a lot more - but this isn’t a bad thing! Nucleus breaks down the timings for commands and any save/load operations on the main thread that might cause lag. This will help you and us in the future trying to pinpoint server lag problems, and whether it’s Nucleus causing them.

Other minor features are:

  • Nicknames now can use most characters, and a regex can be used to restrict what characters and forms nicknames can use.
  • /world create now does not require minecraft: prefixes.
  • Some commands now hide vanished players when pressing tab to complete a command.
  • Added per-world permissions for /spawn (but this is off by default)
  • /kits now shows costs
  • Added the permission nucleus.home.other.exempt.target to allow admins to prevent homes from being disclosed.
  • Add /itemsellall (/sellall)
  • Added ability to warp other players to named warps
  • Add /ping [player]
  • Add /rtp [player]
  • Added clickable location on /seen for players, allows players with the /tppos command to warp to them. This will be expanded upon in a future release.

There has also been a few bugfixes in this release:

  • Sometimes, a server that has two users that have had the same name at different points may have prevented some Nucleus commands from functioning properly. This has been fixed.
  • Some formatting has been cleaned up
  • Some errors have been cleaned up
  • Fixed some link options having the opposite effect to what they should have done.
  • URLs can now include hyphens in their domain names.
  • &r really should work properly now!

There are some known issues and things that you should be aware of:

  • /invsee does not work unless you are within 8 blocks of the target player. Use NucleusMixins to workaround this - though this currently doesn’t work for some heavily modded servers (#506). If you have more information, please add it there.
  • Some players are finding that enhanced pre-generation isn’t giving output (#528). This will work fine in 1.11.x and beyond once I add support for it.
  • While we don’t plan to make changes to the data files, things might change. These will be stabilised by 1.0
  • There is an API, but this is subject to change.
  • Sometimes, an incorrect custom prefix might be selected. Nucleus uses whatever the permission plugin hands back, check your inheritance with the permissions plugin.

A note on GeoIP

GeoIP is disabled by default, and once enabled, will require you accept the third party library licences that are now included in the Jar. We ask that you use the feature responsibly, while we display public data, we understand the privacy concerns.

To use GeoIP, set modules.geo-ip to ENABLED and restart, then set geo-ip.accept-licences to true and run /nucleus reload. The command /geoip update and /geoip <player> will be available to you, requiring the nucleus.geoip.base permission. To display information on login to staff, grant the permission nucleus.geoip.login.

See http://nucleuspowered.org/thirdparty/geoip.html
