    • getBlockEntity

      @Nonnull public static <T extends net.minecraft.world.level.block.entity.BlockEntity> Optional<T> getBlockEntity(net.minecraft.world.entity.player.Player player, net.minecraft.core.BlockPos pos, Class<T> cls)
      Get the relevant target block entity for packet purposes. When the packet is being received on the server, the player's open container is used to determine the BE; don't trust a blockpos that the client sent, although we'll check the sent blockpos is the same as the BE's actual blockpos.

      Important: cannot be used to sync changes after the server-side container could be closed, i.e. don't use this in packets sent from a GUI onClose() method.

      Parameters:
      player - the player, will be null if packet is being received on client
      pos - the blockpos, ignored if packet is being received on server
      cls - the desired block entity class
      Returns:
      the relevant block entity, or Optional.empty() if none can be found

    • getBlockEntity

      @Nonnull public static <T extends net.minecraft.world.level.block.entity.BlockEntity> Optional<T> getBlockEntity(net.minecraft.world.entity.player.Player player, Class<T> cls)
      Server-only variant of getBlockEntity(Player, BlockPos, Class)
      Parameters:
      player - the player
      cls - the desired block entity class
      Returns:
      the relevant block entity, or Optional.empty() if none can be found

    • writeNullableBlockState

      public static void writeNullableBlockState(net.minecraft.network.FriendlyByteBuf buf, @Nullable net.minecraft.world.level.block.state.BlockState state)
      Write a blockstate, which may be null, to the network
      Parameters:
      buf - the packet buffer
      state - the state to write

    • readNullableBlockState

      @Nullable public static net.minecraft.world.level.block.state.BlockState readNullableBlockState(net.minecraft.network.FriendlyByteBuf buf)
      Read a (possibly null) blockstate from the network
      Parameters:
      buf - the packet buffer
      Returns:
      the blockstate, may be null
