Re: How to convert CSV file to FGTAPE file?

Several days ago,I used a flight data analysis tool that is Tacview. I just found I can write a program to control the data import to FGFS through UDP,and control the play progress,speed,loop through a GUI. But that means I have to learn more C++,I'm considering to find similar program's source code...

Re: How to convert CSV file to FGTAPE file?

What exactly would you like to control via Nasal ? There's really just a handful of fgcommands related to the instant replay system otherwise the whole thing is a "black box" that can only be configured via XML/properties. The whole serialization mechanism isn't exposed at all, also it isn...

Re: How to convert CSV file to FGTAPE file?

At present I just work on the minimal flight data ie Lon,Lat,Alt,Pitch,Roll,Heading.
I wonder is there possibility to control the file in stream with Nasal?

Re: How to convert CSV file to FGTAPE file?

I guess, it's your best chance - unless you are willing to tinker with the underlying code. But even then, you will want to make sure that you understand the approach outlined above, and where its limitations are coming from. Realistically, it is going to be more work to write a converter from scrat...

Re: How to convert CSV file to FGTAPE file?

Yeah,it's easy and I realized.
But the problem is that when the simulation speed-up get to x128, the playback duration would reduce to 1/128 in turn.In such case I speed-down the FGTAPE playback,the signal distortion can be very serious,the vision simulation looks so bad!

Re: How to convert CSV file to FGTAPE file?

... merely open the file, remove/adapt the hard-coded constant and then see if your system can handle replaying the CSV file while converting it to a fgtape file.

Re: How to convert CSV file to FGTAPE file?

... you mean If I don't use c++ and rebuild FGFS,I have to use Nasal script to set a fastest sim speed despite of hardware limit and covert it into FGTAPE file automatically. Unfortunately I'm poor at c++,I learned a little Nasal recently through FGFS,now I'm thinking how to write such a Nasal script ...

Re: FG Promotional Video

One note--if you want to make the recording a little easier, try making others do the flying, save as fgtape, then send it to you so that you can just record while the plane is flying.

Re: How to convert CSV file to FGTAPE file?

... of fgcommands to load other CSV files, and control the flight recorder subsystem accordingly - in fact, you could even append CSV to the same fgtape that way. If the 32x speed-up is working properly, you could remove the hard-coded restriction to see if your system can speeding up beyond that. ...

... the time x32 speed, I have to wait too long to save the whole progress manually. I wonder is there any convenient method to convert CSV file to FGTAPE file directly or how can I write such a program to realize that. Thanks again.

Re: How to tell if you are CPU or GPU limited (split)

... could be executed in 2-3 minutes. Concerning pre-recorded flights, those should work for starters, but it does make sense to consider using the fgtape approach instead, because that can be also extended to cover other properties, including those that control other aspects of the simulator, e.g. ...
