Middle Click Pearl
Minecraft Gameplay Impact
In high-pace PvP situations, throwing an Ender Pearl requires manually selecting the item in the hotbar, right-clicking to throw, and switching back to weapons. AutoPearl / FastPearl exploits automate this sequence upon pressing a hotkey (such as the middle mouse button): the module searches the player's hotbar for an Ender Pearl, swaps the active slot, calls interactItem to throw the projectile immediately, and restores the previously equipped slot within 1 tick.
