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.

The spawn can be set in the config. If you set the config to 150 it will then go 150 in each direction making the spawn 300x300 from the coordinates X=0 Z=0. If you want the spawn the same size as your island then you need to set the spawnSize in the config to "half" the island distance.
With the updates to new versions I would suggest to make island sizes in multiples of 32 (and same for the protectionRange) EG. 128(4x32) or 160 (5 x 32) or maybe 320 (10x32). Now for example we take the 320 sized islands (distance), to make the spawn island the same size you have to set spawnSize to 160.
(The reason we are starting to use sizes in multiples of 32 is because of adding a Nether feature which wont generate otherwise.)

I need more info, do "/usb version" and post those details here, a startup log is a good point for me to see to what is going wrong, so if you post that through pastebin would be great.

Yes, that's what I meant. The only economy plugin I have installed on my server is PlayerPoints and it's the only plugin that Valut hooks into. Does uSkyblock not work with PlayerPoints as economy system?

The challenges do not debit the players account they credit the players account. Vault hooks into many plugins, not only "PlayerPoints".
Besides Vault you have to have an economy plugin like EG. Essentials.

Posted Oct 27, 2015Hello! I have uSkyBlock installed on my server, along with all required dependencies. Vault hooks into PlayerPoints for economy, but no money are debited when a player, for example, has completed a challenge. No error in the console.
Is this issue related to uSkyBlock, Vault or to PlayerPoints?

We have not done anything to increase the speed of the crops growing.
There are, as far I know, some settings in Spigot that can be changed but as this is not a uSkyblock issue I'm not sure were to look for this.

I know were the idea is coming from and seen it myself. I don't know how it's done and it looks like a combination of the "plotme" plugin and uSkyblock.
if I knew how he done this I would tell you but unfortunately I don't.

Posted Oct 23, 2015Hello,
I have version Ultimate SkyBlock v2.4.7-b3cf18-361 on my server. Vault: 1.5.6-b49 World edit: Version: 6.1; WorldGuard:: Version 6.1.
I want to make a bridge on the border of the island region, but I dont know how it works. It must be a wooden bridge with fences, so that players can visit the islands of other players without a command. Does someone know how I can make that?
(Sorry for my bad english, I'm dutch ;) )

you can still use the older system to add items to the gui.to do this you need to re-add the following:
Were 7 is the slot number.
The rest is self explanatory to change how you like. In the "command" line change it to your shop command.
Make sure when updating the server with a new uSkyblock version you backup this.

testing this at the moment, but the razorax told me it will always default back to +1 so 2 apples will default to 3 apples. More in an hour as I set my timer on 1 hour (minimum)
EDIT:
After the hour has past the challenge was reset back to 3 apples from 11 (in my case) which worked then as it should.
Take for example the cobblestonegenerator you need 66 for the second time and 68 for the 3rd time, this will be reset back to 66 then after the time is expired.
Hope this makes sense now for you.
@MrFiliper
I have no clue what you mean.
