External flight model

Question

Hi,
I wont use ESP only for graphics rendering and i have external flight model. In input to ESP i have only  alt,lat,lon,Pitch,Bank and Heading. What is best way do it please? I try it via SIMCONNECT_DATA_INITPOSITION but it invite progress dialog.

Answer 1

You need to define your own data struct with the variables you need to set, and then use that data struct to set the position and orientation.  Using the INITPOSITION structure, as you've found out, causes the sim to do a partial reset (reloading terrain, AI aircraft, etc) and is designed specifically to set the Initial Position for an object.

Define my own data structure is not problem, but how set it? Please can you give me some example?

First, set up your structure definition in ESP:

		hr = SimConnect_AddToDataDefinition(_hSimConnect,DEFINITION, "Plane Altitude", "feet",					SIMCONNECT_DATATYPE_FLOAT64, 0.0f, SIMCONNECT_UNUSED);
		hr = SimConnect_AddToDataDefinition(_hSimConnect,DEFINITION, "Plane Latitude", "degrees",				SIMCONNECT_DATATYPE_FLOAT64, 0.0f, SIMCONNECT_UNUSED);
		hr = SimConnect_AddToDataDefinition(_hSimConnect,DEFINITION, "Plane Longitude","degrees",				SIMCONNECT_DATATYPE_FLOAT64, 0.0f, SIMCONNECT_UNUSED);
		hr = SimConnect_AddToDataDefinition(_hSimConnect,DEFINITION, "Plane Heading Degrees True",	"degrees",	SIMCONNECT_DATATYPE_FLOAT64, 0.0f, SIMCONNECT_UNUSED);
		hr = SimConnect_AddToDataDefinition(_hSimConnect,DEFINITION, "Plane Pitch Degrees",			"degrees",	SIMCONNECT_DATATYPE_FLOAT64, 0.0f, SIMCONNECT_UNUSED);
		hr = SimConnect_AddToDataDefinition(_hSimConnect,DEFINITION, "Plane Bank Degrees",			"degrees",	SIMCONNECT_DATATYPE_FLOAT64, 0.0f, SIMCONNECT_UNUSED);
	

.and have a struct for it:

struct PLANE_XYZ_HPR
	{
		double altitude;
		double latitude;
		double longitude;
		double heading;
		double pitch;
		double roll;

	} _PlanePos;

populate the above, then call

	res = SimConnect_SetDataOnSimObject(_hSimConnect,DEFINITION, SIMCONNECT_OBJECT_ID_USER, 0, 0, sizeof(_PlanePos),&_PlanePos );

to set the data.

I have more code if you want to PM me.
