Error sending waypoints array

[Tom@FlagMountain]

I am attempting to send an array of waypoints to FSX via SimConnect.

fsxSimConnect.SetDataOnSimObject(Microsoft.FlightSiimulator.SimConnect,SIMCONNECT_DATATYPE.WAYPOINT,MooneyID,SIMCONNECT_DATA_SET_FLAG.DEFAULT, objv)

I have checked (and researched) all the parameters several times and can't find any problems with the args, but I am getting an FSX Exception 3 every time. There is some forum traffic which suggests that this may be a known issue.

I have done the forum search suggested by FlapsOut, but didn't find any relevant code samples. Anyone got any C# or VB code samples that would help?

Hi Tom

Thanks for going through the posts!

Did you see the application that I kept adding too?

I'll be more than happy to give you the complete Source code for all of that...HOWEVER! It seems your doing something different, and in that regard?

I'll be happy to help develop the C#/.Net code to enable that too?

I sent you a private note too

Thanks,
FlapsOut

Problem solved

All:

I have resolved the problem and now am successfully sending waypoints to FSX via SimConnect using managed code (VB.NET). I believe in sharing, so anyone struggling with this and needing help, just ask.

Yes please

I have created a simulated object succesfully, but can't figure out how to set an array of waypoints on it. I'm using C#.

I have this:

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)]
struct MyWayPoints
{

public SIMCONNECT_DATA_WAYPOINT [] waypoint;​

};

This:

simconnect.AddToDataDefinition(DataDefinition.WAYPOINT,

"AI Waypoint List",
"number",
SIMCONNECT_DATATYPE.WAYPOINT,
0.0f, SimConnect.SIMCONNECT_UNUSED);
​

simconnect.RegisterDataDefineStruct<MyWayPoints>(DataDefinition.WAYPOINT);

And try to do this:

MyWayPoints wps = new MyWayPoints();
wps.waypoint = new SIMCONNECT_DATA_WAYPOINT[fsx.NumberOfPoints];

for ( int i=0; i<NumberOfPoints; i++ )
{

SIMCONNECT_DATA_WAYPOINT wp = new SIMCONNECT_DATA_WAYPOINT();
wp = mywaypointstuff
wps.waypoint= wp;​

}
simconnect.SetDataOnSimObject(DataDefinition.WAYPOINT, targetid, SIMCONNECT_DATA_SET_FLAG.DEFAULT, wps);

My app just crashes, even within VS2005, so I guess something goes wrong in the de/marshaling phase.

Ok, I just found it in the general notes about managed Simconnect clients:

// Step 4: The managed wrapper marshaling code expects a polymorphic array

Now I can set the WP's. My object just doesn't move yet, it does when I set a single WP...

Edit: Ok, also solved, my own plane was blocking it

C# waypoints

Do you have the code for C# to sending waypoints to FSX via SimConnect

From the SDK:

simconnect.AddToDataDefinition(DEFINITIONS.1,"AI WAYPOINT LIST",
       "number", SIMCONNECT_DATATYPE.WAYPOINT, 0.0f,
       SimConnect.SIMCONNECT_UNUSED);

SIMCONNECT_DATA_WAYPOINT[] waypoints = 
                new SIMCONNECT_DATA_WAYPOINT[2];

waypoints[0].Flags = (uint)SIMCONNECT_WAYPOINT_FLAGS.SPEED_REQUESTED;
waypoints[0].ktsSpeed = 100;
waypoints[0].Latitude = 10;
waypoints[0].Longitude = 20;
waypoints[0].Altitude = 1000;

waypoints[1].Flags = (uint)SIMCONNECT_WAYPOINT_FLAGS.SPEED_REQUESTED;
waypoints[1].ktsSpeed = 150;
waypoints[1].Latitude = 11;
waypoints[1].Longitude = 21;
waypoints[1].Altitude = 2000;

Object[] objv = new Object[ waypoints.Length ];
waypoints.CopyTo(objv, 0);

simconnect.SetDataOnSimObject(DEFINITIONS.1, AIAircraftID,
                       SIMCONNECT_DATA_SET_FLAG.DEFAULT, objv);

How to get AI aircraft to show on the radar screen

Thanks for the code Denial. I was able to compile and run the waypoint code, however I want the AI aircraft to show up on the radar screen. Any ideas on how to do that?

 

[Daniel]

I don't know what the criteria are FSX uses to display a plane on the screen or not.

It could be planes added through SimConnect won't show up, maybe only planes with a Flightplan will show up.

What call do you use to create the plane? I suppose all the 'Create....AtcAircraft' versions should work, but maybe they will only show in case they have a Flightplan assigned using SimConnect_AISetAircraftFlightPlan.

Hi,

Sorry for bringing this topic up but I thought it will be pointless creating a new post..

I have created an object and after that applied him 2 waypoints with the above code but doesn't seems to be moving for some reason...

Anyone have an idea what am I doing wrong?
Thanks in advance,

Anyone? ?
