[solved] [1.12.2] getting offline player capability on different online client

Posted September 5, 20196 yr

First of all I have been modding for just over a year now, but this is my first post. With that out of the way, on to the problem.

I have a gui that lists players that have joined in a team with you (the teams are saved in a world capability), and it displays their aura (saved as a capability on the player). This works fine as long as every member of the team is on the server, however if there is a member of the team that is not on the server, opening this gui will cause a crash because the client can not find the player.

the current offending line of code (line 254 of Team Capability class)

this.world.getPlayerEntityByUUID(UUID.fromString(teamnbt.getString(teamkey)))

when the team capability is being deserialized from nbt (after being sent from the server to the client)

(world can be either a client world or server world)

so my main question is, can you get an EntityPlayer instance of an offline player on the client? Can you get the data of an offline player on a client (similar to using player.dat on a server)? Is there another way to display the capability data on the client of the offline player?

similar thread (but this only works on the server instead of the client I think)

also completely unrelated but
Player404

(which is a random player generated by the IDE) is actually registered to a real player

Not really.

Yes you can do this. I've done it recently you need to create an EntityPlayerMP instance on the server and load it's nbt. With a little digging you'll find where the nbt is loaded. Then you need to send the data to the client via a packet. Then store the data until the client player no longer needs it.

alright, so I got a solution

so what I did was when trying to save a client I've been just sending the UUID, now when the client is offline and trying to be saved, I also send the nbt data of the client as well as the username.

then on the receiving side, if the player is not found with the UUID, I call a proxy method to generate a "fake player" to take it's place.

Common Proxy:

	public EntityPlayer loadPlayer(NBTTagCompound teamnbt, String key, World world) {
		
		GameProfile profile = FMLCommonHandler.instance().getMinecraftServerInstance().getPlayerProfileCache().getProfileByUUID(UUID.fromString(teamnbt.getString(key)));
		EntityPlayerMP member = new EntityPlayerMP(FMLCommonHandler.instance().getMinecraftServerInstance(), (WorldServer) world, profile , new PlayerInteractionManager(world));
		FMLCommonHandler.instance().getMinecraftServerInstance().getPlayerList().setPlayerManager(new WorldServer[] {(WorldServer) world});
		member.deserializeNBT(FMLCommonHandler.instance().getMinecraftServerInstance().getPlayerList().getPlayerNBT(member));
		member.mountEntityAndWakeUp();
		
		return member;

	}

Client Proxy:

	@Override
	public EntityPlayer loadPlayer(NBTTagCompound teamnbt, String key, World world) {
		EntityPlayer member;
		if (world.isRemote) {
			GameProfile profile = new GameProfile(UUID.fromString(teamnbt.getString(key)), teamnbt.getString(key + "name"));
			TileEntitySkull.updateGameprofile(profile);
			member = new EntityOtherPlayerMP(world, profile);
			member.deserializeNBT(teamnbt.getCompoundTag(key + "data"));
			member.setEntityId(teamnbt.getInteger(key + "id"));
		}
		else {
			member = super.loadPlayer(teamnbt, key, world);
		}
		
		return member;
	}

Serializing:

	@Override
	public NBTTagCompound serialize() {
		
		requests.removeIf(request -> (request.getSender() == null || request.getReceiver() == null));
		teams.removeIf(team -> team.size() < 2);
		
		NBTTagCompound nbt = new NBTTagCompound();
		NBTTagCompound teamsnbt = new NBTTagCompound();
		NBTTagCompound requestsnbt = new NBTTagCompound();
		
		Integer i = 0;
		for (List<EntityPlayer> team : teams) {
			NBTTagCompound teamnbt = new NBTTagCompound();
			Integer j = 0;
			for (EntityPlayer player : team) {
				if (player != null) {
					teamnbt.setString(j.toString(), player.getCachedUniqueIdString());
					if (player instanceof EntityPlayerMP && ((EntityPlayerMP)player).hasDisconnected()) {
						teamnbt.setTag(j.toString() + "data", player.writeToNBT(new NBTTagCompound()));

Edit your original post.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

Forge and vanilla BlockState generator.

hi i'm new to this. where does "--enable-native-access=com.sun.jna" go?

Hold on, wait a minute. So are you saying that the server you are trying to run is crashing or failing to work properly? If this is the case, then it should have nothing to do with a warning message. Could you be a little more specific as to what's going on? Are you just annoyed that there are some warning messages being displayed? (I mean, if that's the case then I can totally understand.) Again, I notice that you use the word "attempted" when referring to launching the forge server. This gives me the impression that something is going much more wrongly than a warning.

hi i'm new to this. where does "--enable-native-access=com.sun.jna" go?

i am playing on a linux mint distro, and am attempting to run a forge 1.20.1 server

this seems to be the relevant warning message:

WARNING: A restricted method in java.lang.System has been called
WARNING: Java.lang.System::load has been caused by com.sun.jna.Native in module com.sun.jna (union:libraries/net/java/dev/jna/jna/5.12.1/jna-5.12.1.jar%2391!/)
WARNING: Use --enable-native-access=com.sun.jna to avoid a warning for callers in this module
WARNING: Restricted methods will be blocked in a future release unless native access is enabled
