[1.7.2]Sending/Receiving Packets

[memcallen]

I'm trying to use packets to relay NBT data from the client to the server and vice versa, is there a mistake i'm making in the code or is there an easier way to do this?

(sidenote: it's supposed to save an integer "speed")

 

packet code:

 

int Speed;

 

public Packet getDescriptionPacket() {

        NBTTagCompound nbtTag = new NBTTagCompound();

        this.writeToNBT(nbtTag);

        return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord, this.zCoord, 1, nbtTag);

}

 

public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity packet) {

        readFromNBT(packet.func_148857_g());

}

 

@Override

public void writeToNBT(NBTTagCompound nbt){

super.writeToNBT(nbt);

nbt.setInteger("Speed", Speed);

 

}

 

@Override

public void readFromNBT(NBTTagCompound nbt){

super.readFromNBT(nbt);

nbt.getInteger("Speed");

}

In your read from NBT you're not doing anything. You have to set the variable, not just get it.

 

this.speed = compound.getInteger("Speed");

oh yeah i forgot about that part but is there any easier way to do this? also is this the correct way to send and receive packets?

[shieldbug1]

It's how to update information for TileEntities. Another way is to use the SimpleNetworkWrapper.

 

You can take a look at pahimar's EE3 code on GitHub for some examples.

Don't know about shieldbug's method, but that's what I used, works fine!

Ty I will check EE3
