• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Hello,
Does STRUCT LATLONALT return the same set of values as
PLANE LATITUDE, PLANE LONGITUDE and PLANE ALTITUDE?
For the code below, i got matching values for latitude and longitude but altitude values were different. Could anyone guide me on what to set right?
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)]
struct Struct1
{
// this is how you declare a fixed size string
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 256)]
public String title;
public double lat;
public double lon;
public double alt;
public SIMCONNECT_DATA_LATLONALT latLonAlt;


};

enum DEFINITIONS
{
Struct1
}


enum DATA_REQUESTS
{
REQUEST_1,

}


simconnect.AddToDataDefinition(DEFINITIONS.Struct1, "Title", null, SIMCONNECT_DATATYPE.STRING256, 0.0f, SimConnect.SIMCONNECT_UNUSED);
simconnect.AddToDataDefinition(DEFINITIONS.Struct1, "PLANE LATITUDE", "degrees", SIMCONNECT_DATATYPE.FLOAT64, 0.0f, SimConnect.SIMCONNECT_UNUSED);
simconnect.AddToDataDefinition(DEFINITIONS.Struct1, "PLANE LONGITUDE", "degrees", SIMCONNECT_DATATYPE.FLOAT64, 0.0f, SimConnect.SIMCONNECT_UNUSED);
simconnect.AddToDataDefinition(DEFINITIONS.Struct1, "PLANE ALTITUDE", "feet", SIMCONNECT_DATATYPE.FLOAT64, 0.000f, SimConnect.SIMCONNECT_UNUSED);
simconnect.AddToDataDefinition(DEFINITIONS.Struct1, "STRUCT LATLONALT", null, SIMCONNECT_DATATYPE.LATLONALT, 0, SimConnect.SIMCONNECT_UNUSED);


simconnect.RegisterDataDefineStruct<Struct1>(DEFINITIONS.Struct1);

simconnect.OnRecvSimobjectDataBytype += new SimConnect.RecvSimobjectDataBytypeEventHandler(simconnect_OnRecvSimobjectDataBytype);

simconnect.RequestDataOnSimObjectType(DATA_REQUESTS.REQUEST_1, DEFINITIONS.Struct1, 0, SIMCONNECT_SIMOBJECT_TYPE.USER);
simconnect.ReceiveMessage();


Thank you
 
The altitude value being returned in the struct might be quoted in meters rather than feet. Just a thought.
 
Thank you. You are right.
My other doubt is for the line:
simconnect.AddToDataDefinition(DEFINITIONS.Struct1, "STRUCT LATLONALT", null, SIMCONNECT_DATATYPE.LATLONALT, 0, SimConnect.SIMCONNECT_UNUSED);

Don't we put any units in the third parameter? is leaving it as null ok?

Thanks
