“SplineTrack->ScaleVisualizationWidth = 70.f;”
why ?


It looks like there may be an issue with the build a flight tracker tutorial. We are looking into it, thanks for bringing this problem to our attention!


I’m not sure why that line is causing an issue. However, it’s not necessary for the tutorial or for the flight tracker functionality. Removing or commenting out SplineTrack->ScaleVisualizationWidth = 70.f; from the .cpp file should allow you to package without issue.

I’ll update the tutorial to remove that line, thank you again for bringing it up. Let me know if you have any further issues with the project.

a new problem: how to change spline line color to package?
Spline color is red in Editor, but spline color is white, why?
In Editor:

to package:

I’m not sure how to change the spline color in the packaged version. The spline color in editor is set to red in the following lines in PlaneTrack.cpp:

  // Set the color of the spline
  SplineTrack->SetUnselectedSplineSegmentColor(FLinearColor(1.f, 0.f, 0.f));

However, as far as I can tell, SetUnselectedSplineSegmentColor() only applies in editor. You could change the color in editor to white in order to match the color in the packaged version, but I’m not sure how you would change the spline color in the packaged version. The documentation page for USplineComponent may be able to tell you more.
