uSkyBlock
This DevBukkit page is being updated again with current releases and links to the maintained uSkyBlock project. We had lost access to the DevBukkit project page for some time, but have now regained it and are bringing it back up to date.
uSkyBlock is an open-source Skyblock plugin for Paper and Spigot.
Start on a small floating island, build it into something thriving, complete challenges, and team up with other players to push your island further.

Why uSkyBlock
uSkyBlock gives you a complete Skyblock foundation with island progression, deep customization, and a maintained open-source codebase you can build on long term.
Complete Skyblock gameplay. Build your server around islands, progression, challenges, and party play.
Deep customization. Shape the experience with focused configuration including challenge design, biome options, custom islands, and more.
Integrates with your server. Extend uSkyBlock through its public API and placeholder support so it fits cleanly into your server.
Open source with proven lineage. uSkyBlock is fully open source under GPLv3, free to run, and backed by more than a decade of project history.
Maintained for modern servers. Continues to evolve for current Paper and Spigot versions, with new features, docs, support, and maintenance.

Yea we figured out not to go in while in gm1, I do have a question though for the nether I made a portal on my island went through was below nether rack and above lava, is that the way it's to be? We are using usb 2.6.4 on spigot 1.9.4. We followed the directions from the uskyblock.net page. Anyway you're able to come into game and test it for me

If you have read the localization page then you know you can change any aspect of text in the game. Messages and GUI text are all included.
When using one of the programs listed you then need to find the lines you like to be changed.

The /summon Slime or /mob Slime are not uskyblock commands.
When I try these on my server they work normally (saying this, I do have OP). There default MC commands.
A full list can be found here

Hello
If you wanne upgrade yo 1.9 or 1.9.x version yes you do have to update your plugins some will work but most need updating the dependencies are the most imported ; WorldEdit, WorldGuard, Multiverse(core, netherportals and portals) and vault. the chance is big you need to update most of your plugins to 1.9.x compatible versions.
for customization of the output (text) of uskyblock) you can find information on : http://dev.bukkit.org/bukkit-plugins/uskyblock/pages/localization/
and yes there is in uskyblock to clear inventory island and ederchest on island restart of the island.
If you wane clear inventory outside the uskyblock or in other situation there are several plugins that clear inventory on command. the latest dev release has no nether problems, there is a island in the over world and at the same location a island in the nether the portals are working. there is only 1 netportal problem don't enter the nether portal in gm 1 its a know bug of multiverse.
to report any issue's when upgrading have a look at : http://dev.bukkit.org/bukkit-plugins/uskyblock/pages/bug-report/

Posted May 28, 2016Hi, I'm still using 1.8.8 and I really like it, I just have some questions about 1.9 (or latest). Can I use it for my 1.8.8 spigot server, can you change the messages (just want to change the colorcode), what's new in the update, do I have to update worldedit & worldguard and wouldn't that be a problem for my plugins and is there a nether problem? And is there such a command that clear the players their inventory?
Thanks, Mac

I have tested this and as SgtLegoTown already said,
visitors:
is working for me too.
You don't want to protect the visitors from mobs so the config needs to be set to "false"
You want the animals protected so visitors can't kill them then that is set to "true"

Posted May 27, 2016Hey dutchy,
it has been a while,
i have the following problems, players can't kill the Mobs on other player islands while the config has been set to true for mob and animal killing, only animal killing works, after i gave a player the usb.* (only on a testserver) he was able to kill the mobs, so my question is, could you tell me which permission allows to attack mobs on other islands, or what i can change in the config file ?
Best regards, HALOween.
