Subject: [PATCH] Avoid hopper searches if there are no items
|
|
|
|
Hoppers searching for items and minecarts is the most expensive part of hopper ticking.
|
|
We keep track of the number of minecarts and items in a chunk.
|
|
If there are no items in the chunk, we skip searching for items.
|
|
If there are no minecarts in the chunk, we skip searching for them.
|
|
|
|
Usually hoppers aren't near items, so we can skip most item searches.
|
|
And since minecart hoppers are used _very_ rarely near we can avoid alot of searching there.
|
|
|
|
Combined, this adds up a lot.
