So, I'm having a little trouble with NBT.

 

I want to have this TileEntity store 3 values that it'll need in order to run how I want it to.

However, it doesn't seem to want to save and/or load the values for some reason.

 

This is my code:

	@Override
public void writeToNBT(NBTTagCompound nbt)
{
	super.writeToNBT(nbt);
	nbt.setFloat("powerPrev", this.prevPower);
	nbt.setFloat("powerLevel", this.power);
	nbt.setByte("powerState", this.state);
}

@Override
public void readFromNBT(NBTTagCompound nbt)
{
	super.readFromNBT(nbt);
	this.prevPower = nbt.getFloat("powerPrev");
	this.power = nbt.getFloat("powerLevel");
	this.state = nbt.getByte("powerState");
}

 

I really don't see what's wrong with it. This is what vanilla TileEntities seem to use as well.

Are you sure it's not saving correctly, or are you trying to use these values on the client side? If you need the values client side, then you must override the getDescriptionPacket and onDataPacket methods:

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

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

}

@Override

readFromNBT(packet.func_148857_g());
}

 

Thanks for the quick reply! That fixed my problem.
