Summary0000976: Actor action not triggering properly
DescriptionJust like in that report :'http://zandronum.com/tracker/view.php?id=841 [^]'
When lagging/missing packet, actor actions (ex : actor hit fake floor) will not trigger properly..

This is what's causing the famouse flying glitch in whodunit because they used a special script to make people flying when entering/leaving actor.
Steps To ReproduceHost a skulltag server
Load the map
Make you somehow lag
Enter and leave the ladder sector repeatly until the bug appear and you'll fly.

 I don't think that this is related.. in 0000841 the server misses a packet from the client, while in this one it's clearly something that the server decides on.

Anyway I'm testing this with emulated lag of ~600ms and can't reproduce, all I get from jumping off the ladder at the "ceiling" is a desync, not true flight. This is with both 98d and 1.0.

Maybe packet loss is needed for this to happen and skullproxy doesn't seem to be able to emulate that.

 When i try on gv uk server i'm unable to reproduce but torrenting seems to help making the bug, after launching utorrent, it takes 3/4 try to get it.

 How much ping and packet loss do you have when you are able to reproduce this?

 I've had this happen without lag. It was either offline or a LAN server; I can't remember. I was never able to reproduce it.

 I can confirm the issue. There seems to be 2 different desyncs:

* Client thinks that it didn't trigger one of the sector action things. Client and server disagree. Seems to be caused by packet loss.
* Server thinks that the client didn't trigger one of the sector action things. Client and server agree. This can also happen offline. The smaller the sector, the more likely it is to happen.

So this might actually be a ZDoom issue.

 I just tested it with the ladder test 2 wad and it is much easier to reproduce and i found that it works in zandronum without lag online, with multiplayer emulation and just in single player and that this actually works in zdoom 2.6.1.
Should i report this in zdoom tracker ?
