This has been annoying me for the past months, well since I've been playing Dungeons & Dragons Online, that paralyzed characters still move around when getting "paralyzed". Not sure if it's the game, my client installation, my connection, or God punishing me for playing so much. Anyone have a clue?
Part of the problem is lag between the player using an effect that causes paralysis, that instruction being sent from the client to the server, then the server updating the monster, and finally the server sending the updated data back to the client.
This is why the monsters appear to 'slide' to their updated position.
There's no real way to cure lag problems without letting the client override the server update, and that would open up endless avenues for hacks.
