Vessel Length?

[Fengist]

Ok, this shouldn't be buried this deep.  Is there any way to get the vessel length of the flightglobals.activevessel???   I know how to get this in the editor but there doesn't seem to be an easy way to do this once it's out and about.

Thanks

I was not able to find this myself either when I looked for it.

If there is something, it's probably going to be something in the underlying Unity stuff, rather then the KSP stuff.

The one method I did find was the .closestPointOnBounds method which I was able to finagle for my purposes, but I'm not sure how you'd go about using that to get vessel length.

 PartGeometryUtil.GetPartRendererBound or then PartGeometryUtil.GetPartColliderBounds and then PartGeometryUtil.MergeBounds ?

(they returns array so I would not call those each frame)

Thanks @sarbian but... wow... just wow.  That would be an absolute mess to figure out the way I see it.  If you want to get the volume of a vessel, that would work because you end up with a Vector3.  But the length?

That seems like a LOT of work to figure out how long a vessel is.  Isn't there something like this?  

Vector3 dimensions = this.vessel.GetComponent<Collider>().bounds.size;

I know that gives a null ref but isn't there anything like that?

this is how SQUAD calculates ship height (lenght) in VAB.   public static Vector3 CalculateCraftSize(ShipConstruct ship)

	Bounds bounds = default(Bounds);
	Vector3 orgPos = ship.parts[0].orgPos;
	bounds.center = orgPos;
	List<Bounds> list = new List<Bounds>();
	foreach (Part current in ship.parts)
	{
		Bounds[] partRendererBounds = PartGeometryUtil.GetPartRendererBounds(current);
		Bounds[] array = partRendererBounds;
		for (int i = 0; i < array.Length; i++)
		{
			Bounds bounds2 = array[i];
			Bounds bounds3 = bounds2;
			bounds3.size *= current.boundsMultiplier;
			Vector3 size = bounds3.size;
			bounds3.Expand(current.GetModuleSize(size));
			list.Add(bounds2);
		}
	}
	return PartGeometryUtil.MergeBounds(list.ToArray(), ship.parts[0].transform.root).size;

if change ship to vessel we can teoretically get vessel lenght in flight, but, i guess, usefull results will be only when it goes vertically.

Thanks @DennyTX but didn't work.

Put that into a function and got the x,y,z of the Vector3 it returns and I get this.

Vessel x: 46.6925 y:22.34021 z:74.10925

In the SPH, the vessel is listed at 

h:19.4, w:22.2 and l:80.2

The good news is, the vessel orientation didn't really affect those numbers.

 

And I was right.  That's an absolute mess of a methodology for getting the vessel size.

the previous example was for  VAB only

for SPH, SQUAD has another branch, as well as for subassemblies

Right, but I'm not looking to get the size in any editor.  I need it outside.  And when the vessel is out there I shouldn't have to ask where it was created in order to determine it's dimensions.  My god this is ridiculous.  I shouldn't have to be jumping through hoops to get a basic vessel size.  It should be right there along with it's mass.

It s a matter of origin when merging the bounds. The calls I gave you are the right method to do it...
