Method Details

canUse

public boolean canUse(PlayerEntity player)

Returns whether the screen handler can be used.

Subclasses should call #canUse(ScreenHandlerContext, PlayerEntity, Block)} or implement the check itself. The implementation should check that the player is near the screen handler's source position (e.g. block position) and that the source (e.g. block) is not destroyed.

Specified by:

canUse in class ScreenHandler

Returns:

whether the screen handler can be used

quickMove

public ItemStack quickMove(PlayerEntity player,
 int slot)

Quick-moves the stack at slot to other slots of the screen handler that belong to a different inventory or another section of the same inventory. For example, items can be quick-moved between a chest's slots and the player inventory or between the main player inventory and the hotbar.

Subclasses should call ScreenHandler.insertItem(net.minecraft.item.ItemStack, int, int, boolean), and if the insertion was successful, clear the slot (if the stack is exhausted) or mark it as dirty. See the vanilla subclasses for basic implementation.

Quick-moving is also known as "shift-clicking" since it's usually triggered using Shift+left click.

Specified by:

quickMove in class ScreenHandler

Parameters:

slot - the index of the slot to quick-move from

Returns:

ItemStack.EMPTY when no stack can be transferred, otherwise the original stack

See Also:

• ScreenHandler.insertItem(net.minecraft.item.ItemStack, int, int, boolean)

onClosed

public void onClosed(PlayerEntity player)

Called when this screen handler is closed.

To close a screen handler, call PlayerEntity.closeHandledScreen() on the server instead of this method.

This drops the cursor stack by default. Subclasses that have slots not backed by a persistent inventory should call ScreenHandler.dropInventory(net.minecraft.entity.player.PlayerEntity, net.minecraft.inventory.Inventory) to drop the stacks.
