[SOLVED] SimEthereal object not being updated in the current frame

asser_fahrenholz · January 1, 2021, 10:09am

Hello users of SimEthereal

Happy new year, hope you all got through it safely.

I’m trying to track down a bug that I hope you can help me with. As I’m flying through my game world adding forces to my avatar body, suddenly my avatar ship is removed from view. I’m thinking, what the… It seemingly happens at random, I can’t seem to find a pattern when re-trying, but it does happen ever game session at some point - trying to track this down, I work my way backwards and find that the reason it disappears from view is that the BodyPosition is null - This is weird, because I’m moving about, adding forces to the body etc.

I switch on DEBUG level logging for SimEthereal and I get this out in the console just before my ModelViewState removes the avatar:

For some reason, the zone of my entity is being marked inactive. Now, from here I’m not sure where to go. If you have any idea where I should look I’d be grateful. I can’t remember setting zones decidedly inactive/active in my code - that I leave for SimEthereal (I think)

I’ll try to work out how SimEthereal keeps track of active zones

This is where the log message comes from:

github.com

          //

          // Here we only care about the version and not whether it actually

          // moved or not.  So as long as the zones update the version of objects

          // that aren't moving we are clear here.  (And we avoid redoing processing

          // per-client that's perhaps best done globally.) 

          if( !so.isMarkedRemoved() && so.getVersion() < time ) {

              if( log.isDebugEnabled() ) {

                  log.debug("Object no longer in active zones, marking removed:" + so.getEntityId() );

              }

              so.markRemoved(time);

          }

              

          stateWriter.addState(so.getDelta());

          

          if( so.isFullyMarkedRemoved() ) {

              if( log.isDebugEnabled() ) {

Don’t be too focused on the zone part of the message. That log message is just trying to guess how we got there.

Without looking any deeper:

so.getVersion() < time

…to me says “this object wasn’t updated this frame”. I thought I fixed that problem, though.

What version of SimEtheral are you using?

asser_fahrenholz · January 1, 2021, 10:24am

I am on 1.6.0-SNAPSHOT. Thats what I have in my build.gradle at least. I’ll verify to make sure.

asser_fahrenholz · January 1, 2021, 10:27am

Yea, gradle install version of SimEthereal is 1.6.0-SNAPSHOT, and the files are up-to-date with github.

pspeed · January 1, 2021, 10:49am

If it’s always the same object then you might try logging it’s position/orientation to see if it goes wonky right before that.

…NaN position could cause weird issues, for example.

asser_fahrenholz · January 1, 2021, 11:38am

Its always the same mob (my avatar of the player) - I only have one active mob besides some static objects.

Physical body, BodyPosition and spatial info looks to be okay up till the point:

Dont know if this is anywhere near something… but, i’m wondering why the location of the “self” in the NSL is being removed from the entered zone keys:

Driving me nuts

asser_fahrenholz · January 1, 2021, 3:40pm

Edit: nope, that wasnt it

pspeed · January 1, 2021, 7:33pm

Do you set the self ID once and then never mess with it?

it’s been a while since I’ve had issues with SimEthereal but my memory tickles that in one case it was because I was doing weird things with self instead of just setting it during initialization and letting it update zones on its own. I don’t remember exactly what, though. Sometimes when I’m getting an app setup for the first time, I don’t have an entity to hook ‘self’ to and so end up doing something strange… then I forget and it bites me later.

That it still does it with trace logging on is at least something. Means it’s probably not timing related as trace logging should slow things down quite a bit.

P.S.: How long does the game have to run before this happens?

pspeed · January 1, 2021, 7:37pm

I know you deleted this but:
re: “I was sending world positions+rotation to NetworkStateListener - sending local ones instead now.”

Did you mistype? My recollection is that the application code shouldn’t be interacting with NetworkStateListener at all. You send your object updates to ZoneManager (and in world space).

asser_fahrenholz · January 1, 2021, 7:58pm

It varies from run to run unfortunately, can’t find a pattern to it. I am calling the setSelf all the time. I will try only setting it once connection is setup and then leaving it at that.

asser_fahrenholz · January 1, 2021, 8:12pm

The reason I am doing this is a leftover from your demo apps I think. In your CameraMovementState of net-demo (MOSS ref here), you call setView on gameSession, which in turn does this on the server session:

            // Force our viewpoint to the network view.
            // This is a bit of a hack and not officially supported to keep
            // resetting yourself... but it works.
            NetworkStateListener nsl = getService(EtherealHost.class).getStateListener(conn);
            //nsl.setMaxMessageSize(2000);
            if( nsl != null ) {
                nsl.setSelf(avatarEntity.getId(), location);
            }

asser_fahrenholz · January 1, 2021, 8:17pm

Well, it happens when I switch zones and it has to reload, but there’s no pattern to when this is triggered yet

pspeed · January 1, 2021, 9:17pm

I think those two things are related.

I think I hit problems with net-char and ended up fixing it there but I can’t remember.

And yeah, zone crossing is specifically the issue in those cases. I’d randomly see objects come in and out of view because zone transfer wasn’t happening correctly.

Edit: as far as I know, the sim-ethereal examples in simslica/examples still work… so they should be considered ‘canon’ until we discover otherwise.

asser_fahrenholz · January 2, 2021, 4:09pm

This seems to have fixed it (fingers crossed, no BodyPosition disappearing yet). Thanks for the help!
