As noted by John in February, but I did not see it addressed in this thread, is the chase view issue in 2.0. (chase view does not follow heading, and if you select chase while in a turn the viewpoint holds that angle until you leave the viewpoint) I sincerely hope it's not a feature, as there

Has anybody used the --generic record/playback feature recently? It seems to have some very noticeable bugs: When using the --generic record/playback feature, I observe numerous view-related problems: * Helicopter view: the size of the aircraft throbs at a high rate, getting bigger and

Hi John, The first thought that comes to mind is to double check the precision (significant digits) of the data you are writing out. If you are writing out heading for instance with 0 or 1 decimal digits or position with 4 decimal digits, that could account for this sort of thing. Regards,

Right, I wouldn't consider playback.xml to be the most well conceived generic protocol configuration file, but it serves as an interesting example and starting point at least. lon/lat are being written out as a float. This should be switched to double. The format specifier is %f but it might be

A while back I was trying to read in lat/long and found a lot of jitter. I finally found that FG generic was actually only able to read in floats. At that time I found that the designation in the format was just being used for output of variables. But for input they were being put into the

I've only started using the generic protocol stuff very recently. I think there have been some recent (v2.0) patches to fix some of these issues we've been discussing. Originally there was some missing double support, etc. Personally I've never tried the record/playback stuff this using the
