Problems with Sky Dolly on replaying Cessna 152 WBSim flights

Hello,

I am happy with Spy Dolly as replay device, only one thing I cannot figure out.

When playing back a flight with the Cessna 152 WBsim mod, the door are opened in flight and the cocks are on the wheels.

I tried everything I can think of, but I never see a Cessna with closed doors or chocks off etc in replay. I cannot alter this during the replay flight. It does not matter if I start recording and then close the doors etc.

While other planes work fine, as I tried the TBM 930, and that one did not have this problem, while these doors also can open.

Can anybody help with a tips or know why this is possible and what I can do about it?

Greetings,

Boudewijn

Funny, tried the exact Same model Yesterday and Sky Dolly.
I think it has to do with simvars the Programm cannot handle

Ok, thanks for the reply. Sad, but nothing we can do about it I guess then.

That‘s essentially correct: „custom animations and simulations“ are most often implemented using „local variables“ and hence not reported via the official SimConnect „simulation variables“:

https://docs.flightsimulator.com/html/Programming_Tools/SimVars/Simulation_Variables.htm

(If a corresponding variable exists in the first place).

And even if such a customised aircraft would report simulated values (that is, during recording), reacting to such value changes (during replay) is written on an entire different page of the book (same for events).

So if you know the name of the specific „simulation variable“ or IF your aircraft allows to bind the door open/close action to some keyboard or hardware button („event“) - let me know!

That‘s strange. I have to verify this with SU 12 again, but anything that is NOT under control by Sly Dolly (press key V in Sky Dolly to open the „simulation variables“ dialog - that should give you a feeling of what is supported/recorded and what not) you SHOULD be able to change during replay.

In fact, even - to some extend - what IS under control by Sky Dolly, e.g. flaps and gears: Sky Dolly will only control / change them once the recorded value actually changes. Sky Dolly will then simply (re-)set the value once the next „value change“ occurs (of the „simulation variable group“, that is).

(Sky Dolly applies a clever recording/replay algorithm that not only makes it possible to skip backwards and forwards and start/pause replay anytime you wish, WITHOUT first having to reload the entire flight - but this „on value change“ strategy also hugely saves on disk storage, RAM (once the flight is loaded) and valuable CPU cycles).

But Sky Dolly does „freeze“ the „physics calculations“ (during replay only), specifically those which would affect the aircraft position and attitude (otherwise the flight physics would constantly „fight“ the replay position - every replay tool does that). Again, you should be able to control levers and knobs (as described above) - but perhaps your aircraft also (wrongly?) „freezes“ custom simulation logic, such as „open door“ and / or „remove chocks“?

Thanks for the effort, but you are speaking programmer language, and I am just a flightsim enthusiast.

So lets leave it at this. Greetings, Boudewijn

No worries :hugs: I just wanted to be thorough and fully transparent in my reply.

In general, if any „aircraft builder“ or otherwise technical interested person would know about / want to have additional support for any additional „simulation variable“ and/or „event“, please do let me know.
