TileEntity Sync problems [SOLVED]


Bedrock_Miner

Recommended Posts

Hey Guys!

 

I created a new Sign for my mod. The problem is, that I can't sync the sign after exiting the gui, because the method I tried leads to an error.

 

If i click on done in the gui, the game crashes.

 

onGuiClosed

 

@Override
public void onGuiClosed()
    {
        Keyboard.enableRepeatEvents(false);
        NetHandlerPlayClient nethandlerplayclient = this.mc.getNetHandler();

        if (nethandlerplayclient != null)
        {
        	NBTTagCompound comp = new NBTTagCompound();
        	this.te.writeToNBT(comp);        	
        	nethandlerplayclient.addToSendQueue(new S35PacketUpdateTileEntity(te.xCoord, te.yCoord, te.zCoord, te.blockMetadata, comp));
        }
    }

 

 

Important parts of the TileEntity:

 

public class TileEntityLargeSign extends TileEntity {

[...]

@Override
public void readFromNBT(NBTTagCompound comp) {
	super.readFromNBT(comp);
	for (int i = 0; i < 6; i ++) {
		text[0][i] = comp.getString("off" + i);
		if (((ModBlockLargeSign)this.getBlockType()).isRedstoneSign)
		text[1][i] = comp.getString("on" + i);
	}
}

@Override
public void writeToNBT(NBTTagCompound comp) {
	super.writeToNBT(comp);
	for (int i = 0; i < 6; i ++) {
		comp.setString("off" + i, text[0][i]);
		if (((ModBlockLargeSign)this.getBlockType()).isRedstoneSign)
		comp.setString("on" + i, text[1][i]);
	}
}

@Override
public Packet getDescriptionPacket() {
	NBTTagCompound comp = new NBTTagCompound();
	writeToNBT(comp);
	return new S35PacketUpdateTileEntity(xCoord, yCoord, zCoord, getBlockMetadata(), comp);
}

@Override
public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt) {
	readFromNBT(pkt.func_148857_g());
}
}

 

 

And the error screen:

Maybe....

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

 

1.12 -> 1.13 primer by williewillus.

 

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

Well, I now created a class that extends Packet. But how can I get access to the world or the Tile Entities in  processPacket to commit the sended changes?

 

 

package com.bedrockminer.signcraft.client.client.packet;

import java.io.IOException;

import net.minecraft.network.INetHandler;
import net.minecraft.network.Packet;
import net.minecraft.network.PacketBuffer;
import net.minecraft.network.play.INetHandlerPlayServer;

public class PacketSign extends Packet {

public int xPos;
public int yPos;
public int zPos;
public String[][] text;

public PacketSign() {}

public PacketSign(int x, int y, int z, String[][] text) {
	super();
	this.xPos = x;
	this.yPos = y;
	this.zPos = z;
	this.text = text.clone();
}

@Override
public void readPacketData(PacketBuffer buf) throws IOException {
	this.xPos = buf.readInt();
	this.yPos = buf.readShort();
	this.zPos = buf.readInt();
	this.text = new String[2][6];
	for (int i = 0; i < 2; i ++)
		for (int j = 0; j < 6; j ++)
			text[i][j] = buf.readStringFromBuffer(64);
}

@Override
public void writePacketData(PacketBuffer buf) throws IOException {
	buf.writeInt(xPos);
	buf.writeShort(yPos);
	buf.writeInt(zPos);
	for (int i = 0; i < 2; i ++)
		for (int j = 0; j < 6; j ++)
			buf.writeStringToBuffer(text[i][j]);
}

@Override
public void processPacket(INetHandler net) {

}

}

    • There's a scheme I got into where they promised to trade Bitcoin for me and take a cut as a commission. Seemed like a good idea at the time. But then, things went south real fast. They ended up transferring   $190,000 worth of my Bitcoin. I was devastated and felt completely helpless. That's when I stumbled upon the Wizard Web Recovery Tool. It was like a beacon of hope amid chaos. With this tool, I could finally start digging into what went wrong and hopefully get my Bitcoin back. Using Wizard Web was surprisingly easy. I just had to plug in some details about my Bitcoin account and let it do its thing. It started scanning the internet, looking for any clues about what happened to my Bitcoin. It felt like having a detective on my side, searching for answers. And guess what? Wizard Web found some leads. It uncovered evidence of the scheme's shady dealings and helped me track down the people responsible for losing my Bitcoin. Armed with this information, I took the case to court. After a long and hard-fought legal battle, the court ruled in my favor. The perpetrators were held accountable for their actions and faced criminal charges for their involvement in the scheme. It was a victory not just for me, but for anyone who's been taken advantage of by these kinds of scams. Thanks to Wizard Web Recovery, I was able to get justice and reclaim what was rightfully mine. It showed me that even in the face of adversity, there's always a way to fight back. And with the right tools and determination, anything is possible.   The following is the contact information for Wizard Web Recovery.   Email: wizard web recovery((@))programmer . net
    • Hello, good morning. I know some programming and I'm interested in mod creation. That's why I've decided to follow a tutorial guide on YouTube by TurtyWurty. https://www.youtube.com/watch?v=DhoX9cmAZqA&t=160s&ab_channel=TurtyWurty I've followed the tutorial perfectly. The problem is that when checking the food, the texture doesn't load for me. However, everything seems fine no matter how much I check. I'm sure it's something trivial, the problem is that I can't find it. Could you help me solve it, please? I leave a zip of my file so you can edit it freely. forge-1.20-Civicraft.rar
    • If you have nvidia graphics, it's important that you make sure Minecraft (and anything Minecraft-related) is set to prefer high performance graphics first. If you only update your AMD drivers it might fix the issue but cause severe performance loss vs Vanilla as it'll be running on the integrated graphics instead of dedicated nvidia graphics
    • Update your drivers: https://www.amd.com/en/support/downloads/drivers.html/processors/ryzen/ryzen-5000-series/amd-ryzen-5-5600g.html
