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

We didnt erase the versions, we revived the last version and started updating from there.
The older versions are still available on the "Curse" website but you have to do some searching for that.
We "the new team" do not support the older versions then from were we started to update.
Personally I dont see any reason why you cant update to 1.8 and use the current version.
PS. posting here and in my private box is not needed, I answer when I can (but I might start to ignore inpatient ppl)

I went through the challenges.yml and found 2 small mistakes.
In La_petite_sirène you had displayItem: 3496 and it should be displayItem: 349
In Vitrier you had requiredItems:2264 and it should be requiredItems:2264:1
After these were changed the challenges config worked fine for me (see here updated challenges.yml)
PS. It's not Gomez, it's Uncle Fester from the Addams Family

I know what your saying. I'm waiting for the last few fixes to release a new version with many performance updates. As I do not code myself I'm depended on the rest of the team.

Posted Aug 25, 2015Each time someone uses /island restart, the server uses up all my cpu usage and takes up so much ram. Is there a way to prevent it from using all the cpu? Even if it uses less and takes longer. I just don't want it to use all the cpu usage each time... Thanks

Using winrar is not the way it works, you need to do it with the right programs like IntelliJ IDEA or Eclipse. You need to know about coding to use those kind of programs.
However you can use the config.yml and overwrite the existing menu. The first location is 0 and the last on the second row is 17. You will see that 7 and 16 are used already (for the buy and donor perks) but can easily be changed, just keep the format used there.
One of the disadvantage is that when using a return command/button it will go back to the default USB menu. This is trial and error till you get what you want.
The default biome (Ocean) can not be changed in a menu, that is hard coded in the plugin.

Can you post the challenges.yml through pastebin and tell me what version of uSkyblock you use? (do /usb version command)
This will help me to help you.
@MrFiliper
How are you changing the menu.yml? Do you open the .jar and change it in the code or do you use the config.yml?

That would not be possible, the command is for a new island, not a new world. I can say for sure that it wont be added either.

There is not a choice atm for this. You still can have multiple islands with the use of schematics and permissions.
As this was asked before in one of the forums I do think it might be a good idea to have something like this added to uSkyblock. How to go about it will be up to our team of developers.
