FlightGlobals.Vessels has more than just vessels

[linuxgurugamer]

I've come across a problem where the following code gets a lot more than the existing vessels:

            foreach (Vessel vessel in FlightGlobals.Vessels)

A number of the vessels returned are actually null, and apparently asteroids are also considered to be vessels.  Also, some not-null vessels returned don't seem to have a rootPart (it's null).

So is there an easy way to determine if a vessel returned from the list is a valid vessel?

I will point out that in my testing, there is only 1 vessel, yet this list has 8 or more entries.

I am looking at the vesselType, which seems to be helpful.  Is there any other way?

vessel.state ?

vessel.protoVessel.*** (lots of info here)

Parts and root part may be null/empty if the vessel is not loaded, protovessel should contain data.

Unity overloads the equals operator, and returns a fake null for deleted game objects..

Thanks, this will be very helpful

I've never seen a null entry in FlightGlobals.Vessels
But yup, beside asteroids, it also have all debris, flags, breaking grounds surface parts, etc...
