[PART, 1.0.2] Anatid Robotics / MuMech - MechJeb - Autopilot - Historical thread

[Artophwar]

Nope. 1080p here, the tab covers up the resource menu. Has since 2.0.7. Don't know why. Just know it needs to be fixed or it needs to be moveable. There is already a Global MJ config file. Add an adjustment. For this problem to continue is rather annoying when it could be have been fixed a long time ago. People have been reporting this since the fist version after 1.9.8.

I run 1080p as well and the tab is almost near the top of the screen. I am surprised we have gone through a few updates and this issue still hasnt been fixed.

Sarbian's new .dll works great. I only have one issue with it. When using the autodocking. it sometimes fails to orient the craft for the docking. I've had the same ship try to dock nearly backwards (roughly 270 degrees off in orientation) sometimes, other times it does orient properly. To answer the obvious questions, yes, the command pod on the ship is facing the right direction, i.e, not mounted upside down, and yes, in both situations I have clicked "control from here" on the craft's docking port before activating the autopilot. In the cases where it's come in backwards I have deactivated the autodock and manually swung the ship around and once it is facing very roughly in the right direction (maybe 20 degrees out of alignment) and reactivated autodock it will then complete the orientation and proceed to dock. Sample images:

Also, what recourse do we have if r4m0n has lost interest in Mechjeb? Does his license provide for someone taking over or forking the project? I ask because it seems he's not active anymore besides the one quick update when .21 came out.

[Gaius]

Does his license provide for someone taking over or forking the project?

It's GPL3, so, yes.

[sojourner]

Cool, I can't tell a GPL from a hunting license. Was never good at the lawyerly stuff.

In the pictures it seems that the "SAS" modules are activated. You've tried with them off?

[beev20vtq]

Not sure if anyone has came across this issue. I'm using mostly B9 Aerospace parts for my space plane. When I attach mechjeb my controls appear to be switched around. For example, S/W for pitch is now yaw, A/D keys are pitch, Q/E appear to be working fine. I'm also using a pair of VTOL engines from B9. When toggling "VTOL" the left side ends up being reversed(engine exhaust pointing up). Once I remove mechjeb and back to launch, things are normal. I first noticed this when I updated KSP and my mods to the latest version. So I decided to rebuild my craft from scratch thinking something happen during the update. Not so.

Running MechJeb 2.0.9, KSP 21.1

Ok. I did some more testing. The control surfaces were moving correctly on a stock KSP craft along with a stock B9 craft. It's only happening on the craft I made.

Hmmm, that could be the problem. Shouldn't Mechjeb be turning off the SAS itself? It does in every other situation.

[Rassa Farlander]

Question, is it normal for mechjeb to induce a slight roll durning launch? Ive had problems with it rolling and then losing stability after launch. I dont think its my rockets they seem to work fine when I fly them myself

You may need to right click on the tip of your rocket and select control from here as the module is likely on an angle and MJ is getting its initial orientation from there.

I have the same issue. from some of the posts that I read, it seems that NovaPunch is affecting the docking autopilot system. dont know why though. does anyone have a fix for this?

[Toyotawolf]

I don't think Nova Punch is at fault here I think it's MJ2, have you tried a clean install of KSP and docking with MJ2?

For all of you that are having problems, try this.

Go into mechjebs plugindata folder and delete all of the cfg files but the global one. See if that doesn't fix some of your problems. I haven't really had a single problem with it since I did that. I even tried the docking auto-pilot. It worked, but of course it is still super slow and wigs out if you have too much cat physics. AKA reaction wheel torque. Try shutting some of them down.

Does it also remove the throttle fluctuations on auto-ascent?

If that's not the problem try to check the Roll checkbox. I may have broken something

I have noticed that the orientation of the mechjeb part itself is the orientation it thinks is `up` so to speak. I have had to place my mechjeb vertical and facing the right way or my craft burns 180 degrees from the way it should...

I placed it on a probe core and it was slightly off vertical so my craft was always 15 degrees out from the course I wanted.

[King Arthur]

To all of you having so-called angle/orientation "problems", right click your command pod/probe core/remote guidance and click "Control From Here". I'm surprised so many people are not aware of this nor confirming where their ship's point of reference is.

Congrats on the 1,000,000+ Views on this thread guys!! wow, new milestone right there

[John FX]

I have also noticed that sometimes the landing autopilot does a plane change burn then just sits there saying it needs to do a plane change burn of 0m/s and then continues to do nothing else no matter how long I wait. This may be to do with me putting in figures like 25.6 and -9.5 into the landing coordinates (one thing that did it that I noticed is putting a 0 in front like 09.5 which I did once in error). It does not seem to happen if I click a point on the map to select the landing place or select a target to land at like a lander or flag. I`ll try to nail it down.

Does this happen to anyone else?

That is the workaround I figured out also. I, like many people I suspect, did not expect mechjeb to take over as the orientation part and ignore the orientation set by the VAB. I am of the opinion that whichever part/pod/capsule would have been the dominant part should stay that way with a mechjeb unless the user selects otherwise. I`d like to be able to place a MJ wherever I like and not have to manually reset the orientation every time I fly that particular craft.

[sarbian]

MJ don't change the capsule in control by himself. The game changed its way to chose the default command pod.

I wouldn't call it a work-around, that's just how MJ functions. It doesn't do it with crew pods as far as I've seen (but I've not mounted any in weird orientations). It does it with probe and robotic cores though take MJ off and put the rocket on the pad - your navball shows E where E should be. It'd be nice if that got fixed true.

I've built lander missions with 3 or 4 different control nodes though, how should MJ decide which one is 'dominant' at any one point in time? It can't, I have to click the one it needs to be using next and 'control from here'. Same with the docking autopilot - 'control from here' on your docking port so it can orient properly and it docks no bother.

As I said, whichever would have been the dominant part should stay the dominant part. If you change normally by changing `control from here` then that function should not change. If you don`t need to `control from here` to launch your ship then adding mechjeb should not change that.

I've been having the same problem. I tried different probes and got the same reaction every time.

Yeah, that's not it. As stated, I do a "control from here" before activating the autopilot. I think it's the SAS not getting turned off when autopilot is activated. Besides, my MJ unit is on a vertical surface.

So you are trying to launch a space plane with MJ? If so ascent guidance doesn't work for planes, you just....take off and then engage a heading hold if you want....
