Drifting away from the camera?


Recommended Posts

I have a real head scratcher here for you today...

My ship is drifting away from the camera, uncontrollable. AGAIN.

Situation that led to this instance is as follows:

-Launch two probes to Duna on a high energy trajectory in the first few days of the save.

-MCC about 160 days in for both. Low dV on both MCCs.

-First ship arrives, burns into an intercept with Ike, where it will use Ike to perform a reverse gravity assist (to slow down further and save me about 100 m/s dV)

-Ship passes through Ike's SoI without issue, and returns to Duna's SoI.

-Ship begins to drift away from the camera, uncontrollable.

All SoI shifts were done at 1x speed, and all time warps were completed at least 10 seconds before each Soi shift.

Relaunching KSP and using the previous quicksave did NOT clear the issue.

 

Anyone know what causes this and/or how to fix it?

Can't help you with your actual question, sorry (it really is quite a head-scratcher). But, I noticed this bit:

This is not the best practice for SoI changes. They should be done at low "on-rails" time warp (5x-50x), per taniwha's response in a thread talking about patched comics accuracy (third paragraph). 

Anyway, very curious problem, but it honestly sounds more like a bug than a gameplay problem. Maybe try the tech support forum?

Hmm I was having the same problem and determined it was better burn time. But seeing as you don't have that I'm just going to scratch my head and be useless. Do your orbit lines look a bit off when this is happening?

... Didn't know that. I'll rerun the mission in a fresh save.

In older versions of KSP, some parts had problems when you decouple them. They're considered to be a part of your ship, and the camera tries to follow the center of mass as that part moves away.

I don't know if that's what's happening here, but a part pack may be to blame.

VERY interesting. I was unaware of this quirk. I'm going to try again with a non-corrupted save and see what happens.

Yes i'm getting this too, I decouple the previous stage and the camera still focuses on the "center of gravity", despite everything cleanly separated. It even rotates the remaining craft at the edge of the screen in an arc like motion - like as though the mass of the previous stage is still attached. It only seems to correct itself when you speed up the time a bit and the craft returns to the camera center in the middle of the screen again. Sometimes when separating stages as I begin landing the craft, the lander will fall away from the camera and appear to go off in the distance. Again, a brief timewarp will fix this (though not advisable in this instance :wink:

I had this problem on my first 1.1 launch. I time warped and the camera re-focused on my ship again. Then I reset and it hasn't happened since. It was quite interesting.

What do you mean by reset?

It seems that the source of  this issue is MechJeb. - My vessels like to fly out of the screen, every speed change causes this (staging, throttle). The only Mod i have installed is MechJeb ...

... this is sad, because i'm such an awesome bad pilot that i need his assistance :blush:

I don't have Mj and it happened to me.

I dunno if real chute is the problem here, but I do recall it causing similar effects long ago following a ksp update.  Cam stayed centered as if the discarded parts were still teathered.  Usually ending in a kraken attack.  

Point is, make sure your mods are up to date.

Since I can't seem to edit my previous post, I'll do a double. 

The problem still exists in 1.1.2, even after removing MechJeb and Kerbal Joint Reinforcement. Unmanned probes are unaffected, crewed vessels with docking ports either drift or shoot away. The phenomenon is less evident in Kerbin orbit. My Soyuz 7K-LOK/LK, however, is effectively marooned in Munar orbit.
