Use cooldown

The use cooldown (also known as recharge, item cooldown, or simply cooldown) is a mechanic that delays using an item for a given time. It is represented by a transparent white bar that appears over the item in the hotbar and inventory.
Mechanic
For most items that are affected by it, the use cooldown triggers after using the item, and is represented by a transparent white bar that decreases in height as the cooldown nears the end of its duration. The use cooldown affects all instances of a given item type that a player has, not just the one that was used. For shields specifically, the use cooldown activates when the shield has been disabled by an axe. For spears[upcoming Mounts of Mayhem] in Bedrock Edition specifically, the use cooldown activates after performing a jab attack.
