writeGlobalPos

public static void writeGlobalPos(net.minecraft.network.PacketBuffer buf,
                                  net.minecraft.util.math.GlobalPos gPos)

getTE

@Nonnull
public static <T extends net.minecraft.tileentity.TileEntity> java.util.Optional<T> getTE(net.minecraft.entity.player.PlayerEntity player,
                                                                                                   net.minecraft.util.math.BlockPos pos,
                                                                                                   java.lang.Class<T> cls)

Get the relevant target tile entity for packet purposes. When the packet is being received on the server, the player's open container is used to determine the TE; don't trust a blockpos that the client sent, although we'll check the sent blockpos is the same as the TE'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 tile entity class

Returns:

the relevant tile entity, or Optional.empty() if none can be found

getTE

@Nonnull
public static <T extends net.minecraft.tileentity.TileEntity> java.util.Optional<T> getTE(net.minecraft.entity.player.PlayerEntity player,
                                                                                                   java.lang.Class<T> cls)

Server-only variant of getTE(PlayerEntity, BlockPos, Class)

Parameters:

player - the player

cls - the desired tile entity class

Returns:

the relevant tile entity, or Optional.empty() if none can be found

writeNullableBlockState

public static void writeNullableBlockState(net.minecraft.network.PacketBuffer buf,
                                           @Nullable
                                           net.minecraft.block.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.block.BlockState readNullableBlockState(net.minecraft.network.PacketBuffer buf)

Read a (possibly null) blockstate from the network

Parameters:

buf - the packet buffer

Returns:

the blockstate, may be null
