kOS Scriptable Autopilot System 0.9

[doubleg]

Hey love the plugin! I've been automating everything haha! I'm not sure if this is the place but I've found a small bug that you might be interested in. As you know volume 0 can be accessed when in close proximity to Kerbin. As such, i often launch my ships then work on a landing script from LKO. Apparently however if you have an eliptical orbit (my new launching script needs some work ) then you can start writing a script to volume 0 at the low point of the orbit, however if you drift out of range of volume 0 while writing said script then when you save and exit your script will have been lost since the file can't be saved to volume 0. Unfortunately you don't get an error or anything so you assume your script was saved until you try to use it and find it missing from volume 0.

Also, on the readme it says "prograde" "up" and "retrograde" return vectors, however vector commands don't work on them (i.e. prograde:x). Although it looks like "directions" are a way to bypass this.

Once again, awesome job on this mod. I really like how I can automate tasks without feeling like I'm cheating. I can't wait to see what comes in the future.

Also I'm running 0.7 so if any of these are fixed in .82 ignore my post. For some reason .82 doesn't allow me to lock steering or thrust as I've seen a number of people report.

hey, could you make a part for probes or a radial part? that would be amazing!!!

I'd like to see this as well.

Something of similar form factor to an AR202 style mechjeb, where it can be easily attached to an existing vessel or used on an ultralight probe assembly without having to make structural changes.

I was playing with it last night and managed to automate my kethane scanner such that the sensor automatically turns off as the battery runs down, and turns back on as the battery recharges. KOS is apparently able to fire action groups while a vessel is warping, making it quite the solution for my 1000x kethane scanner.

I'll probably add other power management tasks to it tonight, and possibly even a 'phototropism' mode where it attempts to orient the vessel for maximum attainable sun exposure.

Heh... I like that idea. Would be nice to bring the drill in automatically when the tanks are full.

For a radial part, I add the kOS module to the Kerbal Engineer tape drive.

For a radial part, I add the kOS module to the Kerbal Engineer tape drive.

There's some stuff Bizz added to the wiki about how you can go about making any other part in the game into a KOS computer by using another mod that lets you alter the configs of parts.

I'm not using it because I'd rather design craft that work "out of the box" and can be shared, but it does look like a good solution if you don't have that as one of your goals.

[csanders]

Is there an older version available anywhere until there's an update? .82 doesn't seem to work (i.e. "lock throttle to 1.")

[OdinYggd]

Heh... I like that idea. Would be nice to bring the drill in automatically when the tanks are full.

I was thinking even further- making it so that on hitting an action group key it automatically cycles through each kethane converter output in order until all tanks are full.

Along those lines though, can the action groups be set or reset instead of just toggled. Now it may be that I had my action group set to use the toggle action on the parts I was controlling, but I had to do some fudging around with using ints as bools to make it properly track states. Plus it is rather easy to mess it up- the program can only be started with the vessel in a known condition or it ends up having inverted outputs and depriving the ship of power.

Also is the file storage device accessible outside KSP, so that I can make backups of programs that work well when experimenting.

In the wiki http://kos.wikia.com/wiki/Mods I described a way to make all stock drone cores a kOS computer.

That would work for radial parts like flight engineer, too

Well, since the problems the current version has I have uploaded every version I had to google drive. Link in the wiki http://kos.wikia.com/wiki/Issues

I have tried for thirty minutes to find an answer somewhere, but I'm completely stuck.

I find I'm unable to lock throttle. I'm able to set steering, stage, set and print variables, but I can't lock the throttle. I've copied the first few lines from the tutorial video, but no dice.

Shouldn't a simple

lock throttle to 1.

send my rocket flying when I run the program? I've tried setting a variable to 1 and locking the throttle to that, I've tried throttling up and locking my throttle to zero.

I'm really confused.

Edit: I'm running the most recent versions of KSP and kOS on a Mac.

Edit: The issue was running version .82. If you're having the same problem, you can download earlier versions here.

I've read a few pages, but didn't see anything applicable. Can you point to a specific post you think would be helpful?

[Sma]

Wait.. What? There are reddit challenges for kOS?

Just one so far, get into orbit with the least amount of parts, and the least amount of lines (going by the . terminator).

Seeing as that some how you've missed the multiple posts saying lock throttle to 1 isn't working....In the 0.82 update this got broken and isn't working. Look at the post by Bizz right above your post saying you've searched for 30minutes.

I'm aware that it is posted there I'm posting it here as well in hope that it is seen and fixed.

Oh ... I haven't seen that 0.83 is out..

edit found out throttle fixed (at least kevin says that) and eta: still broken.

Did this update do anything with reaction wheels or SAS? I'm having some steering trouble.

[Cheaterman]

Haven't tested the mod yet - love you already for being an IT engineer and would have had developed this myself if time constraints allowed! THANKS A LOT!!!

[dlrk]

Ever since .8, steering doesn't work. Mechjeb steering works fine, so it's not the rocket, and I'm using the same program I used in .7, so it's not that either.

can't confirm that. Made a program to test the eta: problem in 0.82 and used manual throttle (cause I had known that that was broken)

and it had 3 lock steering commands.

• lock steering to up + R(0,0,180).
  
• lock steering to heading 90 by 90.
  
• lock steering to heading 90 by 45.
  

That worked like a charm... So not broken for me. Maybe only with mechjeb?

I believe the "LOCK TO" code breaks a bit further with every new version. In 7.0, every LOCK TO that isn't locked to altitude seems to stop working as soon as any loop or wait is started. And it sounds as if the problem got worse with the 0.8x series.

Also locked variables also get only updated outside from loops when called.

When not they stay at the last value.

Edit: There is something really wired going on.

While a in a program that I wrote eta:apoapsis works perfectly fine.

It doesn't work in space computer anymore... in 0.7 it has!

A moment I thought it has to do something with single and multiple lines, but that's also not true.

stage.
wait 10.
print "after wait.".
if eta:apoapsis > 10 {print "if 1 line ok". }.
when eta:apoapsis > 10 then {print "when 1 line ok". }.
wait 10.
if eta:apoapsis > 10 {
	print "if multi line ok".
	}.
when eta:apoapsis > 10 then {
	print "when multi line ok".
	}.
wait 50.

All lines were executed.

Nice!

For me, in 0.82 pretty much all locks were broken, although it seemed like lock steering would work sometimes, but not all the time, like after a certain time/altitude (when controlling throttle manually).

Also, I'd like to add, it might be a good idea for anyone reading this, to save the previous version zip files you download, so incase you do run into bugs like in that last few updates, you can go back to a previous version that was working. I've got 7 versions from 0.46 to 0.82 (missed 0.8 and 0.81 though) and it takes up less than 3mb. Though you could keep just one previously known working version and delete the others I guess.

Lol from Kevins Dev Blog: "Wheel throttle could be set to 100 with hilarious results" Makes me wish I was testing rovers now.

Ok, so does anyone know where these "flagrant errors" are logged to?
