About this Mod

NBT XP Storage is a mod that allows XP bottles to store NBT containing the amount of XP they will yield once broken. This mod is fully server-side, so no client installation is required.

XP bottles now contain an optional xp NBT tag, which specifies the amount of XP points that the XP bottle will yield once it is thrown and breaks. If enabled, players can shift + right-click while holding an empty bottle to convert it into an XP bottle with a configurable amount of XP stored in it.

Commands

/nbtxp amount - returns the current XP consumption amount
/nbtxp amount set - sets the current XP consumption amount
/nbtxp consumption - returns whether consumption is enabled or not
/nbtxp consumption enable - enables XP consumption by shift + right-clicking
/nbtxp consumption disable - disables XP consumption by shift + right-clicking
