public class InventoryUtils extends Object

  • Field Details

    • LAST_RECIPE_NET_ID

      public static int LAST_RECIPE_NET_ID
      Stores the last used recipe network ID. Since 1.16.200 (and for server-authoritative inventories), each recipe needs a unique network ID (or else in .200 the client crashes).

    • REFRESH_ITEM

      public static final org.geysermc.mcprotocollib.protocol.data.game.item.ItemStack REFRESH_ITEM

    • MAGIC_VIRTUAL_INVENTORY_HACK

      public static final long MAGIC_VIRTUAL_INVENTORY_HACK
      An arbitrary, negative long used to delay the opening of virtual inventories until the client is likely ready for it. The BedrockNetworkStackLatencyTranslator will then call openPendingInventory(GeyserSession), which would finish opening the inventory.

  • Method Details

    • openInventory

      public static void openInventory(GeyserSession session, Inventory inventory)
      The main entrypoint to open an inventory. It will mark inventories as pending when the client isn't ready to open the new inventory yet.
      Parameters:
      session - the geyser session
      inventory - the new inventory to open

    • openPendingInventory

      public static void openPendingInventory(GeyserSession session)
      Called when the Bedrock client is ready to open a pending inventory. Due to the nature of possible changes in the delayed time, this method also re-checks for changes that might have occurred in the time. For example, a queued virtual inventory might be "outdated", so we wouldn't open it.

    • displayInventory

      public static void displayInventory(GeyserSession session, Inventory inventory)
      Prepares and displays the current inventory. If necessary, it will queue the opening of virtual inventories.
      Parameters:
      inventory - the inventory to display
