AI vehicles stucked at waypoints on dedicated server
New, WishlistPublic

Description

AI vehicles get randomly stucked at editor placed waypoints when playing a mission on a dedicated server.
When a vehicle reach a waypoint it will either move immediatly to the next waypoint or stay on position at waypoint for a random time (from 2 to 5 minutes) before moving to the next waypoint. {F27990}

Steps To Reproduce

A repro mission is provided.
In the mission,
The slammer should move after 100 seconds
The Marshall should move after 200 seconds
The Hunter should move after 300 seconds

If you run the mission in the editor, vehicles will respect the times
But once you run it on a dedicated server, most of the time they stay stucked for a few minutes before moving to the next waypoint.

I had this as well, although it was random and the next time we played the same mission it didn't happen. Units would get stuck at a waypoint for a couple of minutes (two or so) before continuing on. This was on a dedicated server as well.

Just to clarify, this happens regardless of how the waypoints are created.

Scripted / Editor placed both have the same issue, assume it's a engine problem somewhere.

Single player with helicopters - helis are floating in one place and ignoring enemy fire.

That happens when they are fleeing

That happens when they are fleeing

Is that expected behavior? Seems counter to the actual act of fleeing, standing still is the polar opposite?

I'm sorry for we're unable to reproduce the issue (AI doesn't take longer than e.g. 5 sec)

AI vehicles get randomly stucked at editor placed waypoints when playing a mission on a dedicated server.

What is the approx. repro rate?
Does it happen only with the delays? Or should it happen when we just let them cycle few waypoints?

Oukej, what server/client version were you using for the tests?

oukej added a comment.Feb 17 2016, 5:38 PM

Internal 1.57.134593 (numbering is basically the same as in Dev branch)

Honestly it's been a while since I was on dev branch but I didn't think there was a proper dedicated server build available (this only occurs in dedicated environments).

Is there an appID I can use in steamcmd to build a test box?

Edit: Did some more reading and got it working, seems to work fine on dev branch, no issues at all. Guess we wait for 1.56 tomorrow in stable and see how it works out there.

Tested in 1.56 stable, working as expected!
