I've just downloaded the newest version of Stendhal and whenver I walk around the world my character seems to studder and jitter all over the map, as if being teleported really fast. This bug occurs while using both the arrow keys (which arent as responsive as they should be) and with click walking. Also, whenever I click to move to a location, sometimes the character doesnt go to that location and just gets stuck walking in the same direction.

    Hello, please give us some more information around your OS, your current Java version and if these lags really just started with the latest client or if they happened earlier as well (like if they became stronger than before or if they didn't show up at all before the update).

    Thank you in advance!

    Greetings

    Do you see high ping times on https://stendhalgame.org/stats/net.html ?

    Yesterday there were reports from our hosting provider about them being under a denial of service attack. While the target of the packet flood was in another datacenter, they warned about a negative performance impact on all data centers.

    I can verify that I also have this same problem too. It is usually worst at times when there is a lot of server lag. This is not a new problem. It has been an ongoing problem in Stendhal for a very long time. I do not think this is a new problem in the latest version, it is probably an issue with network latency or dropped packets or something.

    I think it happens on poor network connections when the client receives multiple than one perception in a too short time frame. First the client needs to move the player backwards because the position from server is too far away from the one where the client would have predicted it to be. Then at the next perception(s) the player needs to be moved again since it's again too far from the new position.

    I don't know how doable a workaround is. If the perceptions are received during one client turn then it might be possible try to coalesce the position changes so that only the last one is taken in account. If not, then probably nothing can be done short of playing on a server that's closer. This would need to be investigated by someone with a somewhat reliably unreliable connection. I have seen it only on mobile net and not too often then either.
