Could you please show me how I would implement this, I'm sorry, I've tried my best, but I am really stuck, not a good day for me. Please reply soon, or message me on the forge forums, as this topic is getting too long

I have made the PacketOutputStream and the PacketInputStream, but I don't understand where I should put the rest. Where should I declare a new PacketWriteStream object and put the tileEntity x, y, and z coordinates in it? Do I declare it in the gui file, or the PacketHandler file?

I try to use the packet to send a message to the server to change it's tile entity when the buttons of the gui are clicked, but it crashes with a protocol exception when I try. I know I coded it to do this, but it was in the tutorial with advanced packet handling. How would you suggest I send a packet to the server with the x y z coordinates when I click a button on the gui?

You solved the problem why it wasn't writing to it's tile entity, so I gave you a thank you. However, I do believe that packet handling would be neccessary, so MineMarteen also helpedd solve this problem. The thing that solved it was I forgot to use the hasTileEntity(int meta) method in my block class. I'll experiment around with some stuff, let you know how the results turned out and if the block successfully reads the stored nbt. Here is some code explained I used a double object to store the height value in the tile entity class so I can call the .toString() method in the GuiGravityLift class. I didn't know you could do that with a primitive. I intend to use the same tile entity for the gravity lift block, so saying which other tile entities I am using isn't neccessary I do know java, quite well actually, but not fully how Minecraft and Forge works. Thanks so much for your help, and MineMarteen's help with the packet handling

Amazingly, this actually works, when the value is changed, the tile entity saves the new height to it's nbt. However, it doesn't read it when I reload the world. Is there anything I have missed, or need to change?

Nope that did not work, but it could explain the nullpointer exception before.

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.

Interesting, I have not thought about making a NBT tag variable. The height variable is changed in the GuiGravityLift.java file under the actionPerformed method when the buttons are clicked, and when the Done button is clicked.

How would you suggest to change the height, should I sent it to the tile entity of the block at the x y z coordinates?

Done, then what?

OK, the PacketBase class is all figured out, what next? Here is the code for the PacketBase PacketBase.java package kris91268.lbd; import net.minecraft.entity.player.EntityPlayer; import com.google.common.collect.BiMap; import com.google.common.collect.ImmutableBiMap; import com.google.common.io.ByteArrayDataInput; import com.google.common.io.ByteArrayDataOutput; import cpw.mods.fml.relauncher.Side; /** * * @author Arbiter * */ public abstract class PacketBase { public static final String CHANNEL = "lbd"; private static final BiMap<Integer, Class<? extends PacketBase>> idMap; static { ImmutableBiMap.Builder<Integer, Class<? extends PacketBase>> builder = ImmutableBiMap.builder(); idMap = builder.build(); } public static PacketBase constructPacket(int packetId) throws ProtocolException, ReflectiveOperationException { Class<? extends PacketBase> theClass = idMap.get(Integer.valueOf(packetId)); if (theClass == null) { throw new ProtocolException("Unknown packet id"); } else { return theClass.newInstance(); } } public static class ProtocolException extends Exception { public ProtocolException() { } public ProtocolException(String message, Throwable cause) { super(message, cause); } public ProtocolException(String message) { super(message); } public ProtocolException(Throwable cause) { super(cause); } } public abstract void write(ByteArrayDataOutput out); public abstract void read(ByteArrayDataInput in); public abstract void execute(EntityPlayer par1EntityPlayer, Side par2Side); }

I don't think you can, if there is, I have never heard of it.

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

And how would I do this? Or should I just remove the check for a remote server?

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.

Thank you so much, you are amazing. I would of figured this out myself, but I did not see that the other method was a new one (notch changed the onBlockPlacedBy method), but anyway, thanks so much. +Thank you

Sorry, but I am not that good with annotations, it never occurs to me to use the @Override annotation. But I do feel stupid about myself because I didn't see this

Please can someone reply to this/help me out, as this is a very urgent bug.

Hello to anyone reading this, I am kris91268, the creator of Light bridges and doors, if you may know On a previous version of Minecraft (1.5.2) My light door rotated correctly when you place it on the underside of a block. But in the 1.6 versions, it doesn't do this anymore, and only can rotate in one way (I would of said one direction, but I don't want to).

Hello, When I run my set of custom Tile Entities with my mod, during game time, it spams the console with errors saying that the tile entity is missing a mapping. What does this mean, and what methods do I need to implement in order to solve this? Any help would be much appreciated

So if anyone knows, how do you register textures that are used for an entity or model block texture?

Never mind, I figured out why Minecraft was throwing a NullPointerException at me, I was refrencing the player as a new object, which was set to null. So I just refrenced Minecraft and called an EntityPlayer message straight from here like this. Minecraft mc = Minecraft.getMinecraft(); instead of Minecraft mc = Minecraft.getMinecraft(); EntityPlayer player = mc.theplayer; And when I needed to display a message in the chat, I went mc.theplayer.addChatMessage("blahblahblah"); I guess you learn from your mistakes
