Posted Jun 24, 2016I've set /island spawn to my regular spawn in World, so I'm not using /island spawn in skyworld. Could I remove the bedrock or should uSkyblock break? I'm using 2.5.7

This might be fixed in a later version then. See if the v2.6.12 has the fix, that version is compatible with 1.8, 1.9 and 1.10

Posted Jun 16, 2016Just to report that party members don't have access to the nether, only the leader. I saw the region info and it only adds the leader as the owner of the island in the nether.

Not much info to go on what you do or what depended plugins you have.
Read the Installation page or read the Bug Report page and then try again. If that doesn't help report back.

I'm not 100% sure that if set to "allow" islands can be griefed, but you can find that out when changing that in the file and do /WG reload

Thank you for your answer. Is there any way I can make it work or not:S? if I set the global flag to build true then the islands will not be protected?

By default players cant break/build outside their island as the "global" region of the skyworld has a "build deny" flag (WorldGuard). This is part of the protections that is needed.

Both thanks for the awnsers.
I dont have skyblock server and skygrid server combined, I have used the uskyblock plugin in my skygrid server. So when the world generated both where on 128 (island size and protection range).
So, players can only break skygrid blocks in there own protection range of 128. Outside these 128 they can't break anything. If the "outside"is owned by another island owner , then its logical. But parts of the skygrid world that are not claimed/has no island protection range on it, still can't be broken. And that is the issue I have.
So I've I get this message in my chat, it's normal. Both pieces of the map are owned by players so you can't break anything. https://gyazo.com/d93ad908c45fc2642a4033546d3a4c56
But if you leave somebody's piece of land, and u arrive and nobody's land you still cant break blocks? https://gyazo.com/9f6c811056e26428074b109f01eca5d0

You can't combine the skyblock and skygrid worlds into 1 world. Each game mode must has to have their own "bungee" server.
However.....
You can create the size of your region a skygrid island and use that as an island they can choose from in the GUI, but with my personal tests this caused lag due to the size and amount of blocks it had to create/paste.
An other downside is that it will always be the same grid which can be abused if players know were to get the good blocks and share them with "normal" islands.

if you have a different number between this 2 settings the border and the distance to the next island yes then there is a "safe" zone also the number must be divided trough /16 and if there are the same then the island connects ..

Posted Jun 6, 2016Hi,
How do I make it so that when people want to build/break outside their island/ If u have skyblock and skygrid combined. players can't build nor break things in inclaimed parts of the map ( where no other island is)
They do get the message "you are leaving ... island"
They do not get the message "you are entering ... island"
So they are in a unclaimed part of the map, but they cant break blocks there?

IF you delete your challenges file does uskyblock not generate a new one ?
like I said I don't have much experience with 1.7 versions ..
