Describe the question
I'm trying to send a packet to update the player's location at the execution of a command.
The onCommand method Overrided works fine, but the packet creation or sending din't works... The player remain in his exact location...
API method(s) used
getProtocolManager(), createPacket(), write() and sendServerPacket().
Expected behavior
Not the error...
Code
If applicable, add relevant code from your project
Additional context
ProtocolManager manager = ProtocolLibrary.getProtocolManager();
Player p = event.getPlayer();
Location l = p.getLocation();
container.getIntegers().write(0, p.getEntityId());
container.getShorts().write(0, (short) 5);
container.getShorts().write(1, (short) 5);
container.getShorts().write(2, (short) 5);
container.getBooleans().write(0, !p.isFlying());
manager.sendServerPacket(p, updatedPacket);
And then, nothings happens...
Please share the code calling createPacket().
Also, please share the complete stack trace of the error you get in the console.
And you should be the latest dev build of ProtocolLib (https://ci.dmulloy2.net/job/ProtocolLib/661/) for MC 1.20.1. Version 5.0.0 is not compatible with MC 1.20.1!
Sure!
This is the compile stack trace:
[14:03:15] [Server thread/INFO]: [ProtocolLib] Loading ProtocolLib v5.0.0
[14:03:15] [Server thread/WARN]: [ProtocolLib] Version (MC: 1.20.1) has not yet been tested! Proceed with caution.
[14:03:15] [Server thread/INFO]: [ProtocolLib] Enabling ProtocolLib v5.0.0
This is the complete method:
@Override
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
ProtocolManager manager = ProtocolLibrary.getProtocolManager();
Player p = Bukkit.getPlayer(sender.getName());
PacketContainer container = manager.createPacket(PacketType.Play.Server.REL_ENTITY_MOVE);
// updatedPacket.getId() return (43 == 0x2B) (Packet ID on the wiki)
// -> REL_ENTITY_MOVE is Update_Entity_Position on the wiki (cientbound)
container.getIntegers().write(0, p.getEntityId());
container.getShorts().write(0, (short) 5);
container.getShorts().write(1, (short) 5);
container.getShorts().write(2, (short) 5);
container.getBooleans().write(0, !p.isFlying());
manager.sendServerPacket(p, container);
return true;
}
At the execution of that method, nothings show up, and the player executor stay in the same location.
And oh... The latest version is compativile with mc 1.20.1?
Yes, you need the ProtocolLib version I linked for 1.20.1 support.
So you are not getting a "FieldAccessException"? I was curious because you mentioned it in the title.
I actually do not think sending REL_ENTITY_MOVE has an affect on the player. It is used to update the position of another player relatively. If you want to move the player you are sending the packet to to another location, use ENTITY_TELPORT.
This will take absolute coordinates though. Here is an example on how to use this packet in 1.20.1: https://github.com/lukalt/PacketWrapper/blob/master/src/main/java/com/comphenix/packetwrapper/wrappers/play/clientbound/WrapperPlayServerEntityTeleport.java
Ok, I tried to import the version you linked me, and rewrite the method to send the packet...
Here is the method with the PacketType.ENTITY_TELEPORT:
@Override
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
ProtocolManager manager = sadLibrary.generics().getProtocolManager();
Player p = Bukkit.getPlayer(sender.getName());
Location l = p.getLocation();
PacketContainer container = manager.createPacket(PacketType.Play.Server.ENTITY_TELEPORT);
// container.getId() return (104 == 0x68) (Packet ID on the wiki)
// -> ENTITY_TELEPORT is Teleport_Entity on the wiki (cientbound)
container.getIntegers().write(0, p.getEntityId());
container.getDoubles().write(0, l.getX() + 5D);
container.getDoubles().write(1, l.getY() + 5D);
container.getDoubles().write(2, l.getZ() + 5D);
container.getBytes().write(0, (byte) (l.getPitch() * 256.0F / 360.0F));
container.getBytes().write(1, (byte) (l.getYaw() * 256.0F / 360.0F));
container.getBooleans().write(0, !p.isFlying());
manager.sendServerPacket(p, container);
return true;
}
By sending the command, running the method, nothing works... Also, in the console no error show up.
I attach also the /protocol dump

Also, I have tried the same method in 1.19.4 and it didn't work...
Please help...
