Solved PacketPlayOutBlockChange in Bukkit 1.13.2

Hello there!

I'm currently implementing PacketPlayOutBlockChange in Bukkit 1.13.2 for my plugin, but the way how the implementation of blocks in the new version changed I don't know how to use this packet anymore.

Could please someone help me out; maybe with a short code snippet?

EDIT: I'm trying to intercept the packet with ProtocolLib when needed and change the block so right-clicking on the fake block won't make it disappear. I somehow have to check what block would be sent and then change the block. I got this working for 1.8.

I have figured it out:

CraftMagicNumbers is a very important helper class that can convert NMS Blocks to Bukkit Blocks in both directions.

Code:

ProtocolLibrary.getProtocolManager().addPacketListener(new PacketAdapter(Plugin.plugin, ListenerPriority.NORMAL, PacketType.Play.Server.BLOCK_CHANGE) {
  @Override
  public void onPacketSending(final PacketEvent e) {
  // [...]
  if(CraftMagicNumbers.getMaterial(packet.block.getBlock())==fakeBlock.getType())
    return;
  packet.block = ((CraftBlockData) fakeBlock.getData()).getState();

fakeBlock is an instance of my own container class. It holds the Material and BlockData of a block.

I figured this out by loking into the source: (CraftPlayer.java)

Code:

@Override
public void sendBlockChange(Location loc, BlockData block) {
    if (getHandle().playerConnection == null) return;

    PacketPlayOutBlockChange packet = new PacketPlayOutBlockChange(((CraftWorld) loc.getWorld()).getHandle(), new BlockPosition(loc.getBlockX(), loc.getBlockY(), loc.getBlockZ()));

    packet.block = ((CraftBlockData) block).getState();
    getHandle().playerConnection.sendPacket(packet);
}
