NBT's are not saving or saving too soon when the game is quit

Hello there,

 

I have implemented a gui to a block that sets it's height for which launches you in the air on contact with the block. When I run the game, I can set different height levels for different blocks, but when I save and quit then reload, they are not saved and are reset to the default value

 

Is there any way for me to save the nbt data when the gui is closed, or when the game is quit? Because I checked, and the tile entities are reading and writing too early.

 

Examples

Any help would be much appreciated

Sorry if I'm no help (I'm still learning), but possible suggestions to try:

 

Perhaps adding @Override just above your initialization of the tile entity within the block class:

@Override
public TileEntity createNewTileEntity(World par1World)

 

Or maybe setting the data to be saved from within the tile entity class:

public void somethingelse(Double newheight)
{
     this.height = newheight;
}

And then calling that method in your GUI class in the onGuiClosed():

public void onGuiClosed()
{
	Keyboard.enableRepeatEvents(false);
	Double theNumber = Double.parseDouble(gravLiftHeight);
	tileEntity.somethingelse(theNumber);
}

 

If I had my dev environment handy, I would test for you before replying to ensure it works, but I'm at work.

All the tutorials on NBT I have read suggest that the Tile Entity itself has to save the data.  Perhaps just passing the data to it does not call the writeToNBT method?

I believe the problem you are having is that you aren't telling the server what is changing in the nbt data, you're doing everything client side, which, upon log out, is discarded. What you will want to do is send a packet to the server, then have it execute the changes as a result of what packet it receives.

Read through these two tutorials:

http://www.minecraftforge.net/wiki/Packet_Handling

http://www.minecraftforge.net/wiki/Advanced_Packet_Handling

(I suggest you do not change any part of your code until after you've read through these, and understand packet handling)

 

Once you get a grip on packet handling, it might become clearer. Basically, where ever you want to change a value in the tile entity of a block, you want to send a packet to the server that tells the server to change the value of the block. That way, you make sure the server knows you're making a change, not just the client. After you've read through both tutorials, if you still are unclear on what you should do, I can try to walk you through getting it to change.

I'm sorry, but I have already looked through those tutorials, and I still don't know what to do, or where I should implement everything. It should be much simpler than this shouldn't it? Thank you already for the help you have given me, it is much appreciated. I will mention you in the mod's credits.

No need to put me in the mod's credits! Packet handling is a bit confusing at first, but once you actually get one working it's simple. I can try to figure out what needs to be done, but it is quite late where I am, so I will take a look at your code tomorrow, sound good?

OK, thank you so much

 

Just a heads up with my code, some of it might be pointless or unccessesary, just ignore them, unless they are of utmost importance

Okay, so first thing you want to do is get the packet framework in place before you change any of your existing code. Create a new class, this will be our base for any packets we send, call it something like PacketBase. In this class you will want to follow the Making the Base for our Packet classes part in the Advanced Packet Handling tutorial I linked to earlier.

 

This class basically implements all the basic stuff needed to create a packet, and it will be the parent class to any custom packets we send. This is also where we will register any custom packets we made. Do this, and post a reply when you are done with this step. If you run into any problem, post here and I will help you figure them out.

OK, the PacketBase class is all figured out, what next?

 

Here is the code for the PacketBase

Okay, next we need a way to receive packets, this is our packet handler, create a new class call CustomPacketHandler and follow the receiving packets section of the tutorial. You will need to change some class names in the code (namely from DemoPacket to PacketBase).

 

This class basically determines when a packet is sent, and determines what it should do with it.

Next is the method that actually sends our packet.  Add the following to your BasePacket class:

        public final int getPacketId() {
                if (idMap.inverse().containsKey(getClass())) {
                        return idMap.inverse().get(getClass()).intValue();
                } else {
                        throw new RuntimeException("Packet " + getClass().getSimpleName() + " is missing a mapping!");
                }
        }
       
        public final Packet makePacket() {
                ByteArrayDataOutput out = ByteStreams.newDataOutput();
                out.writeByte(getPacketId());
                write(out);
                return PacketDispatcher.getPacket(CHANNEL, out.toByteArray());
        }

 

These methods make it so that you can actually send a packet to the server.

Okay, now it is time to make your custom packet. Make a new class named something like, BlockChangePacket, so you know what the packet is doing later without having to look at the actual class. Follow the making our first class part of the tutorial. Under the execute method is where you will want to tell it to change the block. My suggestion is after you finish that part, create a constructor for that class that takes in an integer array, which you would use to send the x, y, and z coordinates of the specific block you want to change the values of, and set three variables (name them what you would like, but x, y and z would be the least confusing) to the values accordingly.

 

Under execute if where will out your code for changing the block's variables. This is where it gets a little involved, so do what you can, and then post here if you get stuck.

Hmm, well I tried to look through your code but I was a bit confused, in your current code where do you change the height of how high the block lifts you?

 

The way I would do it is have an NBT tag called height, which stored and integer. Then for the packet I'd send an integer array that help 4 numbers, the X, Y, and Z coordinates of the block, and the height I want it to change to. Under the execute I would retrieve the tile entity at the X, Y, and Z coordinates, and then set the NBT tag height to the fourth number I sent. Then I would have the block read the NBT tag to get what height it should be lifting to.

Well, either way would work I believe, but basically take your actionPerformed method, and replicate it under the execute command in you custom packet. You will need to first retrieve the tile entity from the correct block, since it's not passed in the packet. After you've done that, post your custom packet code.

I have made all of the files, and tested it out. When I try it out, the game crashes with a null pointer exception. I know it is doing this because there is no tile entity defined, but can't figure out where it is being initialized to null. Here are all of the files that have been updated, focus on the part in the gui where it creates a new packet, and the packet files

Tell me if you need any other files

 

And again, thanks for the help you have given me so far.

Well, I don't think this will solve the nullpointer (could you post the stacktrace?), but here are two things that definately are needed:

 

1. In the GUI class where you send the packet, you're using "PacketDispatcher.sendPacketToAllPlayers()". However, this method is used to send data from the server to all the clients (players). You obviously need the opposite. Use "PacketDispatcher.sendPacketToServer()" instead.

2. Do you have your PacketHandler registered? Make sure you have the @NetworkMod annotation on top of your main mod class (under or above the @Mod annotation). This should work:

 

@NetworkMod(clientSideRequired = true, serverSideRequired = false, channels = {PacketBase.CHANNEL}, packetHandler = PacketHandler.class)

I have all of the required fields under NetworkMod, and if I try using the sendPacketToServer() method, the game just crashes and says that a packet cannot be sent to a server.

 

Here is the stacktrace for using the sendPacketToAllPlayers() method
