How to disable patched conics for a vessel

[pydude]

How can I disable rendering patched conics for a vessel? I want it to look like before you upgrade the tracking station, with just the grey orbit lines. Examples:

(I got the images by taking a screenshot without/with the tracking station upgraded.)

I need to be able to switch back and forth between the two modes, so nothing permanent. 

How can I do this via code?

Switch to another craft. Non-active craft have no patched conics.

[pydude]

@Tex_NLYes, I know that, but I need to still be able to control the vessel. Switching doesn't work here.

Maybe something along the lines of Vessel.PartialControl or something?

[pydude]

@Benjamin Kerman That just changes the control amount. Even if you have no control, the vessel is still tracked, and patched conics are rendered. So that won't work.

There might be something in the Tracking class... i can check

[pydude]

@Benjamin Kerman Did you find anything? Also, what Tracking class are you talking about?

[Benjamin Kerman]

I did find one thing in the Vessel class, https://kerbalspaceprogram.com/api/class_vessel.html#a69e1ba66ab9de6f946adc75b46dbfb19

Vessel.PatchedConicsUnlocked miht help you out a little bit. 

Edit: if you need to find something in the api, just do a search with relevant search terms. I looked up Patched and this was the last result.

@Benjamin Kerman Vessel.PatchedConicsUnlocked apparently doesn't exist . It's listed in the documentation, but doesn't seem to actually be there. 

'Vessel' does not contain a definition for 'PatchedConicsUnlocked' and no extension method 'PatchedConicsUnlocked' accepting a first argument of type 'Vessel' could be found (are you missing a using directive or an assembly reference?)

Seems odd. I tried patchedConicsUnlocked, too, with a lowercase p. Still no luck.

That member is marked as private. That means that members of the Vessel class can use it, but no one else can. It's one of the ways object-oriented programmers protect internal functionality from external dependencies (SQUAD can change or remove private class members, and no mods will break since no mod can use them).

However, Vessel.patchedConicRenderer is public. What happens if you set vessel.patchedConicRenderer.renderEnabled = false, or mess with the other properties of that object?

Oh. I'm such a noob at c#.

Setting renderEnabled to false doesn't work. It seems to change back to true by itself every frame. I had actually already tried that before starting this thread. I'll have look at some of the other properties, though.

[Benjamin Kerman]

Yeah, that would make sense becuase it looks like it is set as a constant in the program... 

@HebaruSan, would it work if @pydude made a new instance of a vessel and changed that private value? Are private values hidden from even members of their own class?

Sorry but do you throw dart on a board to generate your replies ?

I dont know what you mean.

@sarbian I believe @Benjamin Kerman is talking about this quote when he says " it is set as a constant in the program.."

He wasn't responding to your post.

Okay, so I've made a little bit of progress. Using this code

for (var i = 0; i < vessel.patchedConicRenderer.patchRenders.Count(); i++)
                {
                    vessel.patchedConicRenderer.patchRenders[i].visible = false;

                }

, I have stopped the conics from rendering. However, there are some problems.

First, the conics sometimes flicker in if you zoom in and out in the map view. They only show up for a split second, but for my intended use, this would be a problem. How do I stop this from happening?

Second, the orbit lines are not rendering. I don't know how to draw the orbit, but not the encounters. How can do this?
