  • Method Details

    • onButtonClick

      public boolean onButtonClick(PlayerEntity player, int id)
      Called when player clicks a button with id.

      "Button click" is an abstract concept; it does not have to be triggered by a button. Examples of button clicks include selecting a recipe for a stonecutter, turning a page of a lectern's book, or selecting an enchantment on an enchanting table. Buttons are identified by an integer.

      Overrides:
      onButtonClick in class ScreenHandler
      Returns:
      whether the button click is handled successfully

    • 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

    • setProperty

      public void setProperty(int id, int value)
      Sets the property with ID id to value.

      Subclasses can call ScreenHandler.sendContentUpdates() to manually sync the change to the client.

      Overrides:
      setProperty in class ScreenHandler

    • 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
