My TileEntity stores an Integer called "storedpower". This integer is loaded from NBT on game start, and written to NBT on the game save. when I read it from NBT, my integer only loads on the server side, and not on client side.

Now, this TileEntity has a GUI, which can display this "storedpower" Integer. But since GUI is on the client, and the Integer is on the server, I cant get it to display the proper value. Now I am wondering, how I should go about syncing the client with the server, that I can display the proper value. I tried onDataPacket, but I can't quite understand how to use that properly.

Side note: I only want to sync the data in TileEntity#readFromNBT.

solved!

@Override
    public S35PacketUpdateTileEntity getDescriptionPacket() {
        NBTTagCompound tagCompound = new NBTTagCompound();
        this.writeToNBT(tagCompound);
        S35PacketUpdateTileEntity pack = new S35PacketUpdateTileEntity(xCoord, yCoord, zCoord, 0, tagCompound);
        return pack;
    }
    @Override
    public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt) {
        this.readFromNBT(pkt.func_148857_g());
    }

 

this did the trick!
