Frequent disconnects from realms and dungeons

[iremnant]

Version info

• nrelay version: 8.8.6
• RotMG version: X31.0.1

Plugins

• Follow (unreleased)
  • Uses features
    • ResourceManager.objects
    • PlayerTracker
  • Uses packets
    • MapInfoPacket
    • UpdatePacket
    • NewTickPacket
    • TextPacket
    • UsePortalPacket
    • TeleportPacket

Steps to reproduce

1. Start nrelay
2. Enter realm or dungeon
3. Walk around for a couple of seconds, shoot enemies etc
4. Suddenly get kicked out

Result

The bot is disconnected with no error except:

[XX:XX:XX | Main Client]        Received failure 0: "Lost connection to server"
[XX:XX:XX | Main Client]        Received socket error: read ECONNRESET`

Seems like an object getting hit multiple times in a small period of time triggers it? Almost certainly related to hits in some way. I can walk around as much as I like but when enemies are near they tend to disconnect after a while. Happens in all dungeons. I'll keep you posted as I look into this.

Perhaps related: The client and specifically autonexus seems not to take external healing into account. After taking a bunch of 20dmg hits and repeatedly being healed by a maxed out priest, the client thinks its at hp levels way lower than they really are (client thinks 120, but really its at 840). This isn't corrected in any way and might be the cause of these disconnects (desync?)

Dealing with projectiles has been a long running effort in the development of nrelay. As you can see, it's still not quite perfect. This is probably something that will require a lot of time and effort in order to debug and fix properly, and unfortunately I don't have the time right now. I'll leave this issue open as it is something I would really love to fix eventually. Thanks for the insight into the priest healing, I'll keep that in mind when I have some time to work on this!

Fantastic. I'll keep you posted in case I look into it myself.

Just to add to this issue it is directly related to whether or not autoaim is enabled or disabled.
