    • findOrCreateItem

      public static void findOrCreateItem(GeyserSession session, org.geysermc.mcprotocollib.protocol.data.game.item.ItemStack itemStack)
      See findOrCreateItem(GeyserSession, String). This is for finding a specified ItemStack.
      Parameters:
      session - the Bedrock client's session
      itemStack - the item to try to find a match for. NBT will also be accounted for.

    • findOrCreateItem

      public static void findOrCreateItem(GeyserSession session, String itemName)
      Attempt to find the specified item name in the session's inventory. If it is found and in the hotbar, set the user's held item to that slot. If it is found in another part of the inventory, move it. If it is not found and the user is in creative mode, create the item, overriding the current item slot if no other hotbar slots are empty, or otherwise selecting the empty slot.

      This attempts to mimic Java Edition behavior as best as it can.

      Parameters:
      session - the Bedrock client's session
      itemName - the Java identifier of the item to search/select
