S_EVENT_PLAYER_LEAVE_UNIT

[FlightControl]

Anybody having any idea why sometimes the initiator field in the event S_EVENT_PLAYER_LEAVE_UNIT is empty???

 

This happens only in multi player.

 

@Grimes, is this a reported bug?

 

See the serialized unmodified EventData that i receive (element 2 of the array):

 

EVENT00000.onEvent({[1]="S_EVENT_PLAYER_LEAVE_UNIT",[2]={["id"]=20,["time"]=28237.301,},[5]=-1,})

 

There is no way to know which player has left which unit?

There is an old bug report where it was occurring if people are selecting slots, though I think it was a SP only issue when it was reported. Any instances of it occurring earlier than 7 hours into a mission that might give a better idea of what could be causing it?

Hi Grimes, thanks for reaching out.

 

I ran this morning a test for the new tasking engine in the framework with another person and also using his server.

 

So we ran a MP mission on 1 dedicated server, 2 players logged on as a client to the server. And this situation appears soon, when we changed slots.

 

DCS version 1.5.6.

 

I also saw this in the logging on the server:

 

01318.206 INFO    NET: onPlayerSlot(3, 144)
01318.206 INFO    NET: passed onPlayerTryChangeSlot
01318.206 INFO    NET: release unit 140
01318.206 INFO    SCRIPTING:   5123(    13)/E:               EVENT00000.onEvent({[1]="S_EVENT_PLAYER_LEAVE_UNIT",[2]={["id"]=20,["time"]=28237.301,},[5]=-1,})

 

To my current understanding, there wasn't an slmod or something like that running on the server. (Wasn't my server).

 

I will do some more testing on this issue here at home, until I better understand the scenario when this occurs. Maybe you can do this kind of test also?

I don't have a second PC capable of running DCS to test stuff like that on my own. If it occurs as host it is easy enough to reproduce.

I will do some more tests in a MP setup (server and client), and will report back. I am currently installing a server on my machine (under another user).

 

You can run a DCS server on the same machine, just create another windows user and logon, install dcs, and run as a server with 3D render disabled. No mods or anything.

 

Then back on your normal windows user, you can connect to the server using IP 127.0.0.1. (localhost).

 

The only thing you need is sufficient memory, like 12GB. CPU is not an issue if your PC has 4 cores, DCS only uses 1.

It is a bit of a hassle to switch between users, but it is functional.

 

An alternative could be to install a VM, but that works slower and costs extra f.e. a new windows install license.

It is really strange. So I've been doin tests on my local machine.

So run a DCS Server on a local Windows user session (3D off etc), and then connect to this server using IP 127.0.0.1 from a full DCS Client.

 

And guess what... Now it works, and I just cannot resimulate this problem.

The initiator field is correctly provided and no problem finding all the relevant fields, including player name...

 

Note that this is a test with one remote player connected on a local host...

 

But I do see the same messages appearing (the 3 lines of NET in the front)... So that is not the issue neither ...

Talked too soon... Here is a problem situation ...:

 

Initiator is nil !!! And this without any network, just on localhost.

Found it!

 

The event S_EVENT_PLAYER_LEAVE_UNIT is also fired when the player

is connected to the server from a client machine, and when he does

the following actions:

 

1. Select from spectators a slot (plane).

2. Don't press "Briefing", but immediately select another slot (plane).

 

Then the S_EVENT_PLAYER_LEAVE_UNIT will be fired when switching slots, but no initiator field will be populated!

 

So, this is something that is worth sharing to the community.

Don't consider this to be a bug. I can easily fix this in the framework in the event dispatcher, now I know why this happens.

 

There is no loss of information neither. When a player joins a unit and flies, and then does Quit, Back to Spectators or just leaves the sim, the S_EVENT_PLAYER_LEAVE_UNIT is correctly fired with the initiator field populated.

 

@Grimes; Don't submit a ticket, not needed! Sorry for disturbing.

Sounds like it is just an evolution of the existing bug anyways.
