On a creative mode server I play on, there are custom barrels players can use that when placed already have some items in them. I believe this is done with modifying NBT data. How can I achieve this, with plugins or in vanilla?
For reference, the server uses the following plugins: CoreProtect, Essentials, LuckPerms, NBTAPI, PlotSquared, WorldEdit. I can't use
/give but can use
/powertool. It is on version 1.16.4.
