edox677 Posted December 4, 2014 Report Share Posted December 4, 2014 Hi there, I'd like to change the position as well as bank, pitch and roll angles of the aircraft. I managed to write the desired angles but I cann't change Lat/Lon/ Alt There is this remark [Can be written to move aircraft: in FS2002 only in slew or pause states]. Does this mean at can be written only to FS2002 OR only in slew mode in FS2002 meaning does it work in FS2004 at all. Heres is the code I used in C++ void FS9WriteInterface::writeLatitudeDeg(double latDeg) { long long Latitude; DWORD dwResult; Latitude = latDeg /90.0 * (10001750.0 * 65536.0 * 65536.0); if (FSUIPC_Write(0x0560, 8, &Latitude, &dwResult)) { FSUIPC_Process(&dwResult); } } Cheers Maik Link to comment Share on other sites More sharing options...
Pete Dowson Posted December 4, 2014 Report Share Posted December 4, 2014 I'd like to change the position as well as bank, pitch and roll angles of the aircraft. I managed to write the desired angles but I cann't change Lat/Lon/ Alt You can change all at once, and (in FSX at least) even set the airspeed at the same time. You write from offset 055C (or 0558 with airspeed) and set LLAPBH (Lat Lon Alt Pitch Bank Heading), all in one structure. In FSX you can alternatively write individual values. There is this remark [Can be written to move aircraft: in FS2002 only in slew or pause states]. Does this mean at can be written only to FS2002 OR only in slew mode in FS2002 meaning does it work in FS2004 at all. It means that it only works in FS2002 when you first set slew or pause mode. That didn't apply to FS98 and FS2000 (which is when FSUIPC's interface first appeared). I'm afraid I don't actually recall whether that also applies to FS2004 -- it may well do. I haven't been involved with FS2004 for many years. Try it and see. Have you checked that the right value is being written? Use logging (Monitor offset 0560), or use FSInterrogate -- that latter utility is an essential for debugging FSUIPC applications.

mgh Posted December 4, 2014 Report Share Posted December 4, 2014 I cannot offhand remember the precedence rules for C/C++ but have you tried this: Latitude = latDeg * (10001750.0 * 65536.0 * 65536.0) /(90.0); Link to comment Share on other sites More sharing options...
