Crash when SE_GetRoadInfoAtDistance method called for a vehicle created by SE_AddObject method

[Genco2]

Hello Everyone;
I am working to create a new vehicle(2 vehicles were already existing, new one is the 3rd one) at a given time. I am using SE_AddObject function with no problem.
When following code block executed ;
`

                insertedID = SE_AddObject("insertedVehicle", 1, 0, 1);
		printf("ID : %d \n",insertedID);
		y = SE_ReportObjectPosXYH(insertedID, 0, vehicleState.x, vehicleState.y, vehicleState.h, 10.0);
		SE_GetObjectState(insertedID, &insertedObjectState);
		insertedVehicleHandle = SE_SimpleVehicleCreate(vehicleState.x, vehicleState.y, vehicleState.h, 4.0, 10.0);
                    ...
		SE_SimpleVehicleGetState(insertedVehicleHandle, &insertedVehicleState);

`

I obtain the new vehicle just where I wanted which is the same location as the vehicle with vehicleState struct and can reach insertedObjectState struct. However when I tried to call SE_GetRoadInfoAtDistance function to obtain steer angle for the newly added vehicle;
y = SE_GetRoadInfoAtDistance(2, 5 + 0.75f * insertedVehicleState.speed, &roadInfo, 0, true);
simulation crashes without a message. May first idea is maybe the vehicle created by the "SE_AddObject" method does not have "pos_.GetHRelativeDrivingDirection() " . Does anyone have any idea ?
Thanks a lot.

Thanks for this report, sorry for delayed response.

You sure found a bug. Root cause was a reference to a member in the not yet created visual model. The problem is that when adding a vehicle, the actual 3D model is not created until the SE_Step() method is called. And actually, even when created it was not done fully correct (bug).

This should be fixed by commit 084f57d. However, the commit only fixes:

1. Avoid referring to non existing 3D model
2. Create 3D model correct after AddEntity()

So you still need to run SE_Step() at least once to 1. have the model created and 2. update the sensor info. So i suggest you add a SE_StepDT(0.0) somewhere before SE_GetRoadInfoAtDistance(), or postpone that call to next frame.

Thanks a lot for the help, always happy to use Esmini :) Closing this issue.
