TileEntity Datawatchers

[david476]

Is there a way to use Datawatchers in a Tile Entity, I think my variable might not be loaded clientside on world load.

[david476]

how would I go about doing that

 

[david476]

just a float, it gets set after Tile Entity creation and should stay the same until the Tile Entity is deleted. The variable does get set client side on creation but not on world load.

[david476]

If it matters the variable could actually be anything but a float would lessen the amount of programming I have to do

[david476]

How do I set it's NBT, there is a function that uses nbt but it does not have a proper name.

[david476]

could someone refence me to a vanilla example of this, I can't figure out how to search through the forgesrc library.

I would assume that the furnace would be a good place to look for it.

 

Oops.. Scratch that. The furnace doesn't use it.

[david476]

how do I pass or receive the nbttagcompound? so far I have:

 

public class TileEntityController extends TileEntity {
public float rotation;

@Override
public void writeToNBT(NBTTagCompound nbt) {
	super.writeToNBT(nbt);
	nbt.setFloat("rotation", rotation);
}

@Override
public void readFromNBT(NBTTagCompound nbt) {
	super.readFromNBT(nbt);
	rotation = nbt.getFloat("rotation");
}

@Override
public Packet getDescriptionPacket() {
	new NBTTagCompound().setFloat("rotation", rotation);
        return new S35PacketUpdateTileEntity();
    }

@Override
public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt) {

}
}

 

(sorry, new to all this)

A vanilla example is a sign.

Ok, figured it out! I was trying to use a method named the same thing but with different parameters. Finished code for people with the same problem:

 

package com.deb.debmodularships.tileentities;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.network.NetworkManager;
import net.minecraft.network.Packet;
import net.minecraft.network.play.server.S35PacketUpdateTileEntity;
import net.minecraft.tileentity.TileEntity;

public class TileEntityController extends TileEntity {
public float rotation;

@Override
public void writeToNBT(NBTTagCompound nbt) {
	super.writeToNBT(nbt);
	nbt.setFloat("rotation", rotation);
}

@Override
public void readFromNBT(NBTTagCompound nbt) {
	super.readFromNBT(nbt);
	rotation = nbt.getFloat("rotation");
}

@Override
public Packet getDescriptionPacket() {
	NBTTagCompound nbttagcompound = new NBTTagCompound();
	nbttagcompound.setFloat("rotation", rotation);
        return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord, this.zCoord, 1, nbttagcompound);
    }

@Override
public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt) {
	rotation = pkt.func_148857_g().getFloat("rotation");
}
}

notice how you have fancy pants writeToNbt and readFromNbt methods. You supply them a tag compound and they will write data to the compound, or take the data and read it. Use them.

[brandon3055]

As Alix said you already have methods to read and write your nbt data so just change what you have to

package com.deb.debmodularships.tileentities;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.network.NetworkManager;
import net.minecraft.network.Packet;
import net.minecraft.network.play.server.S35PacketUpdateTileEntity;
import net.minecraft.tileentity.TileEntity;

public class TileEntityController extends TileEntity {
public float rotation;

@Override
public void writeToNBT(NBTTagCompound nbt) {
	super.writeToNBT(nbt);
	nbt.setFloat("rotation", rotation);
}

@Override
public void readFromNBT(NBTTagCompound nbt) {
	super.readFromNBT(nbt);
	rotation = nbt.getFloat("rotation");
}

@Override
public Packet getDescriptionPacket() {
	NBTTagCompound nbttagcompound = new NBTTagCompound();
	writeToNBT(nbttagcompound);
        return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord, this.zCoord, 1, nbttagcompound);
    }

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

 

Edit: Fixed typo

 

[david476]

Good call! (note, Brandon put tagCompound instead of nbttagcompound if anyone copies) Thank yous for EVERYONE!!!!

[brandon3055]

oops i just copied that from one of my classes

[david476]

s'OK! Thanks again!
