Possible v5 traffic limiter problem

[vgbaron]

Hi Pete - 

I have both P3d3 & 4 on the same system. I have MyTraffic6 installed in it's own location and the path is installed in both v3&4.

Starting at the same location, same flight, same date and time, same % traffic. Running registered FSUIPC 4 & 5 respectively with this in the ini file:

[Traffic Limiter]
TrafficLimit=100
AirportPreference=70
GroundPreference=20
NearerPreference=70

 

In v3 I see 6-8 AI parked next to my a/c - in v4 I see 0-2.

If I change to TrafficLimit=0 and nothing else -  then I see 6-8 in v4 also.

Whether it's V4 or FSUIPC - I haven't a clue but there it is.

Thanx,

Vic

Hi,

the code base for that will not have changed in FSUIPC5 compared to FSUIPC4. Did you try the MyTraffic forum first to make sure there is no change in P3Dv4 with MyTraffic because of AI change in P3Dv4?

As well as what Thomas suggests, use the Traffic Explorer from the SDK to check the actual total number of aircraft and their distributions. Depending where you are and the numbr of nearby airports the parked traffic could vary a lot. The difference in 0-2 and 6-8 in a limit of 100 is not significant when the elmination performed by the Traffic Limiter algoithm is randomised in any case. The numbers for the parameters are only biassing the random selection, so it would need larger numbers or a long period of changing traffic (comings and goings) for that to amount to those exact relationships.

ok, I see what you're saying - I'll dig a little further. Burkhard has been recovering from an illness so there's been no changes to MYT6 for a while.

My puzzlement comes from the fact that I can repeat the process with both sims and get the same results. I'll look at the Traffic Explorer and see if it provides any clue.

Not a big deal, just curious.

I understand that, but I've got no other answer. Sorry. Maybe it is timing related, because the random number generation is seeded from the elapsed time in milliseconds when the facility is initialised.

I can look to make it a bit less repeatable by adding time of day and date and so on to the seed, if it will help make more sense?

No Problem Pete. I'll dig into my system more and see if something else is causing the issue.
