This hook is called whenever a hopper transfers an item from its own internal storage into another block entity. A plugin may decide to disallow the move by returning true. Note that in such a case, the hook may be called again for the same hopper and block, with different slot numbers.


Callback function

The default name for the callback function is OnHopperPushingItem. It has the following signature:

function MyOnHopperPushingItem(World, Hopper, SrcSlot, DstBlockEntity, DstSlot)

Parameters:

NameTypeNotes
WorldcWorldWorld where the hopper resides
HoppercHopperEntityThe hopper that is pushing the item
SrcSlotnumberSlot in the hopper that will lose the item
DstBlockEntitycBlockEntityWithItems The block entity that will receive the item
DstSlotnumber Slot in DstBlockEntity's internal storage where the item will be stored

If the function returns false or no value, the next plugin's callback is called. If the function returns true, no other callback is called for this event and the hopper will not push the item.


Code examples

Registering the callback
