NTB Daten speichern

[ErfinderLabyrinth]

Hi

I have a TileEntity and want to save NBT data

for this I have the following methods

@Override
public CompoundNBT getUpdateTag() {		// TODO Auto-generated method stub
	return this.save(new CompoundNBT());
}

@Override
public SUpdateTileEntityPacket getUpdatePacket() {
	CompoundNBT compoundnbt = this.getUpdateTag();
	return new SUpdateTileEntityPacket(this.worldPosition, 2, compoundnbt);
}
@Override
public CompoundNBT save(CompoundNBT p_189515_1_) {
	super.save(p_189515_1_);
//	if (!this.trySaveLootTable(p_189515_1_)) {
//		ItemStackHelper.saveAllItems(p_189515_1_, this.items);
//	}
	LogManager.getLogger().info("save-start");
	java.lang.System.out.println("save-start");
	ListNBT listnbt = new ListNBT();
	LogManager.getLogger(System.modid).info(listnbt.getElementType());
	int i = 0;
	for (String s:list) {
		System.out.println("save-write-" + i);
		CompoundNBT compoundnbt = new CompoundNBT();
		compoundnbt.putInt("id", i);
		i++;
		compoundnbt.putString("message", s);
		listnbt.add(compoundnbt);
	}
	System.out.println("save-save");
	p_189515_1_.put("Text", listnbt);
	System.out.println("save-finished");
	return p_189515_1_;
}
@Override
public void load(BlockState p_230337_1_, CompoundNBT p_230337_2_) {
	super.load(p_230337_1_, p_230337_2_);
//	this.items = NonNullList.withSize(getContainerSize(), ItemStack.EMPTY);
//	if (!this.tryLoadLootTable(p_230337_2_)) {
//		ItemStackHelper.loadAllItems(p_230337_2_, this.items);
//	}
	ListNBT lnbt = p_230337_2_.getList("Text", 10);
	for(int i = 0; i < lnbt.size(); ++i) {
		 CompoundNBT compoundnbt = lnbt.getCompound(i);
		 String ms = compoundnbt.getString("message");
		 list.add(compoundnbt.getInt("id"), ms);
	}
	
}

However, the save method is not called

What am I doing wrong

Use the predefined tag type constants, don't hardcode random magic numbers here.

How do I get the predefined tag type constants

Show more of your code, specifically the whole TileEntity class, your Block class and the registration for both.

Thank you

Why not new ItemStack(Items.ACACIA_BOAT)?

Expand  

Didn't know this was possible

  Quote

Uh, what?

Expand  

This was only temporary to get to the super method getUpdatePacket (I noticed the green arrow to the left of the method afterwards)

  Quote

Why is this static? It makes no sense for it to be.

Expand  

For the static method getTileEntity()? (PS: I have to look here again in the tutorial, because I think that I made a mistake here)

  Quote

You must also call TileEntity#setChanged after changing any data that is saved to disk.

Expand  

What does the method do? Does it send the NBT data to the server? If so, how can I check the NBT data from the server?

Neither should be static.

Expand  

However, the getTileEntity() method from the constructor in code

this(window, inv, getTileEntity(inv, data));

is called and without the static Java would complain

2.Question: How do I save the NBT(i.e. how do I run the save() method), setChanged() did not work

And again: Please keep this forum in English.

Sorry, forgot it again, but I just translated it again

[ErfinderLabyrinth]

  Quote

You must set the data on the server side

Expand  

? How does that work?

[ErfinderLabyrinth]

  Quote

You must send a packet to the server with the data. The server must then validate that the player can do this (the client can lie, never trust it blindly). Then the server must save this data.

How?????

[ErfinderLabyrinth]

Thanks for the link, but I don't understand which parameters to pass on registerMessage() (see Registering Packets)

Where can I find Forge's code?

Edited February 12, 2022 by ErfinderLabyrinth
Translation from German to English

[ErfinderLabyrinth]

Under which link are the codes of the tutorial in Github or where can I find the code in the IDE

 

PS: Sorry that I forget to translate some Reply into English, but as soon as I notice this I change it to English

[ErfinderLabyrinth]

And what is the name of the sample file? According to Eclipse, there is no SimpleImpl class

[ErfinderLabyrinth]

One more question: How can I check if the code is running at the client or at the server

[ErfinderLabyrinth]

For the Level class I have the class io.netty.util.ResourceLeakDetector.Level, java.lang.System.Logger.Level, java.util.logging.Level, org.apache.logging.log4j.Level and org.spongepowered.asm.logging.Level, but none of the classes has the method isClientSide(). What am I doing wrong or is the class a subclass of another class?

[ErfinderLabyrinth]

Sorry I forgot this. I'm still programming on 1.16.5, but will soon switch to 1.18.1+.

[ErfinderLabyrinth]

But how do I get a world instance(I dont programming this in a class extends TileEntity).

[ErfinderLabyrinth]

I have now solved the problem like this:

DistExecutor.unsafeRunWhenOn(Dist.CLIENT, () -> () -> /*CODE to execute when the method is executed on the client*/);
DistExecutor.unsafeRunWhenOn(Dist.DEDICATED_SERVER, () -> () -> /*CODE to run when the method is executed on the server*/));

Can you solve the problem in this way or does this cause problems?

[ErfinderLabyrinth]

What is a distribution and what is a logical side?

[ErfinderLabyrinth]

Thanks for the link. I have now improved the code a bit and I want to know if the code is still causing problems

DistExecutor.unsafeRunWhenOn(Dist.CLIENT, () -> () -> {
	if (Thread.currentThread().getThreadGroup() == SidedThreadGroups.SERVER) {
		SimpleChannelMessage.handleServer(msg, ctx);
	} else {
		SimpleChannelMessage.handleClient(msg, ctx);
	}
});
DistExecutor.unsafeRunWhenOn(Dist.DEDICATED_SERVER, () -> () -> SimpleChannelMessage.handleServer(msg, ctx));

 

[ErfinderLabyrinth]

The only problem is that I build this module-based and I can't be sure if the packet is sent to the server or to the client.

[ErfinderLabyrinth]

Because of code that I have already programmed or will program

Das bedeutet nichts. Sie sind derjenige, der die Nachricht sendet. Dieselbe Nachricht sollte immer vom Client zum Server oder vom Server zum Client gesendet werden, niemals beides.

Unfortunately, I can't prevent this, because you should also write mods on this mod again
