Questions About Asteroids (and the Orbit Class)

[ve2dmn]

I'm trying to find which Asteroid are on a collision course for Kerbin and I can't seem to get the info from the orbit Class.

Vessel.orbit.closestEncounterLevel always seems to be None for not active vessel;

Similar results for (all return false, none, null, etc...) :

• orbit.closestEncounterBody
  
• orbit.closestEncounterPatch
  
• orbit.nextPatch
  

The only information I need is the altitude at periapsis around Kerbin, if there is one. (Then set to Asteroid to be auto-tracked, Which I know how to do thanks to http://forum.kerbalspaceprogram.com/threads/75376-Asteroid-Spawn-API )

But so far, if the vessel is OnRail (AKA not the active one), I cannot get any orbit information besides the current orbit. (and I can't get Orbit.SolveClosestApproach to work)

Any idea?

To reply to my own post, This is code that made Patches possible.

if (!v.PatchedConicsAttached) {
				print("No PatchedConicSolver. Creating a New One. ");
				v.patchedConicSolver = new PatchedConicSolver ();
				v.AttachPatchedConicsSolver ();
				v.patchedConicSolver.Update ();
			}

I still have to figure out why it works Sometimes, and sometimes, it gives my a NullReference Exception for AttachPatchedConicsSolver ()...

But at least now I have Encouters and NextPatch in the robit of each vessel (just need to remember to run v.DetachPatchedConicsSolver () once I have the info I need....)

Career mode ? Fail when the tracking station is not upgraded ?

Asteroids do not spawn if the tracking station is not upgraded...

These are exactly the 2 questions I came to this sub-forum to ask.

However I can't see on the linked thread anything about making an asteroid tracked. I want to start tracking an asteroid at the moment that the player accepts a contract involving it. At the moment I have the regretable situation that a player can accept a contract only to find that the asteroid involved gets deleted immediatly afterwards.

edit:

Found this discovery line

vessel.DiscoveryInfo.SetLevel(DiscoveryLevels.StateVectors | DiscoveryLevels.Name | DiscoveryLevels.Presence);

Will this be enough to prevent it from being deleted?
