Storage and XP

Item storage

Items are kept separately by item type and NBT data. The largest quantity appears in the top-left slot of the first page. Visual slots show one item while a custom label shows the actual quantity, so the vanilla stack count is not displayed.

A newly unlocked spawner starts with one page of 36 slots. Once a slot reaches capacity, the same item continues in the next eligible slot.

When storage is full

If every allocated virtual slot is full, virtual spawning continues but excess item drops are not stored. XP storage continues.

XP and Liquid Experience

• The Withdraw XP button gives stored XP to the player.
• The same XP is stored as apotspawner:liquid_experience.
• The conversion rate is 1 XP = 20 mB.
• Liquid Experience cannot be placed with a bucket; it is intended for tank and pipe automation.
