interactWithFluidHandler
public static boolean interactWithFluidHandler(@Nonnull Player player, @Nonnull InteractionHand hand, @Nonnull Level world, @Nonnull BlockPos pos, @Nullable Direction side)Used to handle the common case of a player holding a fluid item and right-clicking on a fluid handler block. First it tries to fill the item from the block, if that action fails then it tries to drain the item into the block. Automatically updates the item in the player's hand and stashes any extra items created.- Parameters:
player
- The player doing the interaction between the item and fluid handler block.hand
- The player's hand that is holding an item that should interact with the fluid handler block.world
- The world that contains the fluid handler block.pos
- The position of the fluid handler block in the world.side
- The side of the block to interact with. May be null.- Returns:
- true if the interaction succeeded and updated the item held by the player, false otherwise.

If the player is in creative mode, the container will not be modified on success, and no additional items created. If the input itemstack has a stacksize > 1 it will stow the filled container in the given inventory.

getFluidHandler
Helper method to get anIFluidHandlerItem
for an itemStack. The itemStack passed in here WILL be modified, theIFluidHandlerItem
acts on it directly. SomeIFluidHandlerItem
will change the item entirely, always useIFluidHandlerItem.getContainer()
after using the fluid handler to get the resulting item back. Note that the itemStack MUST have a stackSize of 1 if you want to fill or drain it. You can't fill or drain multiple items at once, if you do then liquid is multiplied or destroyed. Vanilla buckets will be converted to universal buckets if they are enabled. -
