[Solved]How to get altitude from specified transform

[flywlyx]

I want to figure out the altitude from one transform on the model but not the vessel center.

Following code didn't give a reasonable reading. I want to calculate the altitude beyond the sea so raycast can not help(Maybe?).

Any help will be appreciated.

Transform[] detectorTransform = part.FindModelTransforms(detector); //Get the transform position
vector3 relativeposition = detectorTransform.position - vessel.Transform.position; // calculate the distance between detector and vessel center
float height = vessel.altitude + relativeposition.y; //give out result

The issue is that relativeposition.y has no relation to the body a vessel is above, rather it is probably straight up in World space co-ordinates that everything orbits in.

If you are in a roughly equatorial orbit, relativeposition.y will be roughly 'north' as relative to the body you are orbiting.

For what you want, I think there is a method you can call to get altitude directly, something like FlightGlobals.GetAltitude(Vector3) if I remember right.

I think you want a single transform, not an array.

Transform detectorTransform = part.FindModelTransform(detector); //FindModelTransform without the s
float height = mainBody.getAltitude(detectorTransform.position);

You are right, FlightGlobals.getAltitudeAtPos(Vector3) is more easier.

I always make more silly mistake like thsi:blush:thank you
