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.

I had the same issue when initially starting to use WG 6 - it turned out (for me at least) to be the Factions plugin, that had no monsters spawn in Wilderness.
So, I blamed WG for a week, then fixed Faction and all was working. Just a possible cause.

I had creepers and spiders spawning while in the ocean biome and when changing to forest the rest spawned, see pic here. This all in 1 mc night.
@MineLab

Yes I know about that, so why uSkyblock doesn't update for WG 6 (on 1.7.9) ?

I checked all my files again and I changed my island to each biome and went a full night cycle, still nothing. I'm using WG 6.0 with the latest skyblock on a 1.8.1 spigot.. Mobs spawn in the main world, just not in the skyblock one. Just curious as to whether there was any more insight you could give me, you've been great so far, prior to this, wasn't really even aware the island biome affected mob spawning. Tried that though, and still nothing. If i have to try downgrading to WG 5.9 or something to see if it works then I will.

If you had WG v6 then it not supose to happen indeed (if you were on a 1.8 server) these settings can be changed in the config, when using WG v5.9 they can grief that way.
Only thing I do know you can stop in WG 5.9 is the creeper explotions/damage and crop trampoling is by adding this
into the plugin/worldguard/worlds/skyworld/config.yml were the { } is. This some little protection but better then nothing.

Actually I have a bungee server. I use WG 6.0 on my PVP server and it's working fine, but on my Skyblock server I still use WG 5.9 for protecting islands.
But visitors of any island are able to "trample crops, kill animals, shear sheep and kill mobs", are you saying to me that it is not expected ?

Nice to know, but some flag handling is different then the v5.9.
Can you check a few thing like "trampeling of crops, killing animals, shearing sheep and killing mobs" by visitors of the island (when warps are enabled for example).

Well, I use WorldGuard 6.0 Beta 5 on my server, which is running on 1.7.10, and it seems to work correctly..

Yes, it suports the UUID. WorldGuard v5.9 isnt compatible with Craftbukkit/Spigot 1.8 as of many updated features and WorldGuard v6 doesnt work properly with Craftbukkit/Spigot 1.7.x because of those updated features. This is the main reason we had to bring out 2 versions. So the WG in 1.7 doesnt use the UUID.
@NightHavoc
We havent changed anything to do with the mobspawning (as far I know of), you might need to check the biome your in as that can influance the spawning of mobs. I will look into this sometime later today.

Posted Jan 27, 2015Was just curious as to whether this plugin blocks mob spawning or not? I have all my worldguard, multiverse, server, spigot, and essentials files all to allow mob spawning, yet nothing spawns in skyblock worlds... this is a major issue for my players.. lol
Just wondering whether that's a feature/bug with this plugin.. I don't have any other plugins that are preventing it though. Thanks

So uSkyblock now supports UUID in 1.7.9, but what about WorldGuard 6.0 ?
Because WG 5.9 still use playernames..

We have added a new version for servers running 1.7.9/10.
New in this version:
Both versions are updated the same only the 1.7 version has different WorldEdit/Guard dependecies with different set of flags.
EDIT: The command /is top or /island top is broken and will be fixed soon with a hotfix A simple fix is to add in the config: options:

- The latest versions have UUID implemented.
- Updating from V2.0.0 beta should not be a problem as the configs are automatic updated now ( do check when your not using the default value's, just incase)
- We are working on a 1.7 build but as explained it was not ready for release.

Posted Jan 25, 2015Thanks for answering me, but I have one more question to be sure:
Will there be / is there a version that is:
- 100% compatible with UUID
- migrate from BETA 2.0.0
- compatible with spigot 1.7.x (with protocol 1.8) ?
Keep up the good work !! :D

The current version has been tested - and should work - but, as always proceed with caution. And... don't use /plugman load/reload/unload with uSkyBlock for the time being.

Depending on from what version you update. let us know what you use is the best way for us to tell you then.
Make sure you have all the dependencies.
Were working (with haste) on a update that will have an option to protect all island with WG as this seemed to give some problems.

I know Dutchy has made some guides as to how to configure a skyworld_nether. But currently, no, we don't have support for "nether-islands". See https://github.com/rlf/uSkyBlock/issues/10
Edit: The nether-guide on debo is located here: http://debocraft.x10.mx/skyblock/troubleshoot.html
