LockShulker plugin
includes the mechanics of opening a shulker in the air, and the shulker also has mechanic levels, namely
First-level shulkers, where there are only 9 slots for maintenance Second-level shulkers, where there are a little more slots
Third-level shulkers, you have an almost full-fledged shulker Fourth-level shulkers, this is the most common shulker Now what does the
Command plugin consist of! Well, how can we do without them? /lockshulker reload - reloads the /lockshulker give shulker configuration plugin (shalker level 1 to 4)
Features Plugin for opening a shulker in the air Allows you to open a shulker without placing it, yes, I know, there are many such plugins, but this one, when opening a shulker, it is replaced by a barrier, which in my opinion protects against duplicates a little better (and should look nice) the item material can be completely changed in the plugin configuration Protection from duplicates As I said above, the plugin also provides protection from duplicates, it is always being improved, because if someone found a bug or a duplicate, I immediately fix it Config.yml. Here you can configure everything that is there, in the plugin messages of each material and so on.

If you found a bug, please contact me so that I can fix it.
