Need help with getting 1.9.x and beyond's orbits to work like 1.7.3 and before.

[Borv413]

Ok, So I just got started in a new 1.9.1 modded save after mostly staying in version 1.7.3 pretty much since 1.7.3 was released. When I was planning a maneuver node to transfer to another body, the patched conics were showing encounters several orbits in the future. This is the reason why I don't play versions past at most 1.8.1. In my opinion, it makes KSP unplayable for all Intents and Purposes. I hugely prefer for the orbital predictions to show what happens on the first and only the first orbit. I have done many, many, gravity assists in versions 1.8.1 and before, and how the game predicts orbits is perfect for what I want to do. For me It makes the best sense to me. I have no clue why SQUAD did away with this feature.

So, does anyone know how to make 1.9+ orbits work like 1.8.1( preferably 1.7.3) and before?

 

Also this is my first real thread

Can you show an example of what you're referring to? I don't think anything like that was changed since the 1.7.3 version.

Here's what I'm talking about.  Note: this video is in 1.10 in a personal dev version of NH.

Sorry, but I can't really understand anything in that video. The font is unreadably small, and it's not clear what the context is. Is that Kerbin?

I cropped out everything else/

 Also this is not the install that i was having problems on, It would take like 30mins to boot up the install that I had problems on. But it is on a version after 1.9.

Have you tried changing the patched conic settings? Maybe they're set differently in your 1.7.3 install as compared to your 1.9.1 install.

(Apologies for the ugly screenshot, the ones I found in an image search were photos of screens.)

[Borv413]

no, They are both set at 6, and the draw mode is relative

Just to be clear, you're saying that on 1.7.3, you would not see this encounter?

"no" you would not see it, or "no" my interpretation is wrong?

So, recently, I just started playing in 1.9.1 after playing in 1.7.3 since it released, and For some reason the map screen shows encounters even after after the current orbit. this makes it ultimately unplayable for me. Is there anything I can do to fix this?

Overlapping threads have been merged.

Something definitely changed in 1.9: the changelog says they messed around with time warping and a pretty nasty trajectory bug (engaging timewarp rounds something down in the orbital calculations, causing just enough of the craft's current orbital energy to vanish into the ether to make precise interplanetary encounters impossible due to the closest approach changing every single time timewarp is turned on and with enough timewarp on/off toggling miss the target body's SOI entirely) appeared around the same version as well, so I wouldn't be surprised if an undocumented change, possibly performance-oriented, messed things up.

So yes, something is definitely wrong with the orbits in the game. Haven't seen this particular issue you're pointing at, though, as my patched conic setting is too low for it.

install principia, problem solved.
