I don't think it would display your new position on your screen if you simply sent the packets. Most trainers source code I have seen simply edit the memory address for the player's x and y coordinates, and leave it up to the Graal Client to send the packets with the new position, so the memory editing is probably vital to the whole 'warping around' action.
