Subject: [PATCH] Optimize Hoppers
|
|
|
|
* Removes unnecessary extra calls to .update() that are very expensive
|
|
* Lots of itemstack cloning removed. Only clone if the item is actually moved
|
|
* Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items.
|
|
However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on.
|
|
* Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory
|
|
* Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration
