I got a TileEntity that has also a Container and a Gui.

 

That said, it has only one slot and i write the contents to NBT and also read it.

 

When i put the itemstack inside all works perfectly. But when i log out and relog in, the server seems to be working fine (things are happening) but the client is not recognising the item inside unless i open the gui. Then all the animations that depend on that item can trigger after that.

 

Anything i missed? Packets? Sever or client only things? "!world.isRemote"?

 

EDIT: this is the TileEntityCode. I'll explain a bit.

People recommended S35PacketUpdateTileEntity.

 

Look at TileEntityFlowerPot@getDescriptionPacket for example.

Okay! thanks! gonna explore that.

SOLVED

 

Thank you very much.

 

This is what i added to the TileEntity:

 

public Packet getDescriptionPacket() {
	NBTTagCompound nbttagcompound = new NBTTagCompound();
	this.writeToNBT(nbttagcompound);
	return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord,
			this.zCoord, 5, nbttagcompound);
}

public void onDataPacket(NetworkManager net,
		S35PacketUpdateTileEntity packet) {

	readFromNBT(packet.func_148857_g());
}
