HopperSleeper

HopperSleeper

HopperSleeper reduces server tick load by stopping idle hoppers from polling every tick.

When a hopper is empty and has nothing to pull, it is put to sleep.
The hopper is woken instantly when a real vanilla event occurs, such as:

• an item entity entering the hopper area
• a container above changing contents
• items being inserted into the hopper

This preserves vanilla behavior while removing unnecessary block entity work.

Improvements

• Lower MSPT in hopper-heavy worlds
• Reduced tick-time spikes
• More stable TPS on servers and singleplayer

_Note: tested in a superflat, peaceful difficulty world with over 100 hoppers present._

The mod does not add blocks, items, or configs, and does not modify world data.
It only changes how often idle hoppers run their logic.
