MechJeb Autom8 Scripts Megathread

[Corovaneer]

Is it possible to make such a script that would produce the effect of a button pressed?

For example, if I use Damned Robotics in ascent stage, and I need automatic control on hinges that are with 0 and 9 by default?

[olex]

I have scripts working and will post a few when they are polished. Am I able to do

print vessel.altitudeASL

and 'report' to the window the vessel's current height? How would I do this (assuming it's even possible).

If you print something that isn't a string, you need to enclose the argument in ():

print(vessel.altitudeASL)

[togfox]

Thanks for that - the next obvious question is string concatenation. print "craft altitude is now " & (vessel.altitudeASL)

(I haven't tried that btw!)

Is it possible to expose total fuel on board or total fuel in current stage? Loving the scripts.

String concatenation operator is "..", example:

print("Altitude is "..vessel.altitudeASL)

No functions for total fuel yet afaik, you need to find and access the single tanks to get fuel amounts.

I'm having a problem with the mun script, i have named it to just mun and when i enter dofile "(mun)" it says:

What's wrong?

dofile("mun")

make sure the "" are inside the brackets and your file is in the right place. If you post your script then we can check it out for you.

Here are four scripts, all basically modifications of R4m0n's FlyMeToTheMun.

With <a href="http://pastebin.com/C4nDeKEk">KMun</a> I changed the name, typing in FlyMeToTheMun (capitalization required) got real old, real fast. I added a variable to input Kerbin Orbit Altitude and it adjusts Pe (one time using the original, it warped me into Mun).

<a href="http://pastebin.com/VQJrQXgg">KMin</a> was just the next logical step. Lands on Minmus.

<a href="http://pastebin.com/82iTeTrW">KMunO</a> gets you into Mun orbit at the input altitude.

I'll let you figure out for yourself what <a href="http://pastebin.com/Qfnp6YVw">KMinO</a> might do.

To use, open autom8 and type in dofile("filename") then click execute.

This will give you "usage". Hopefully that is clear. Capitalization and spaces are required. Click execute.

<font color="red">Warning:</font>

On both Minmus scripts insure that you will not be caught in Mun's SOI. If you don't know how to do that, from the launch pad go to the orbital map (default M) and if necessary time warp until Mun is out of the way. Strange things happen if you are caught in Mun's SOI on the way to Minmus.

I'm also attaching a zip file (because that's what I know) that you can just unzip into KSP\plugindata\mumechlib.

Finally, if the scripts aren't working for you, try cleaning up your system. After uncountable times running and rerunning the scripts to make sure they worked the way I wanted, one more try didn't work. WTF! I ran <a href="http://www.wisecleaner.com/wisecare365.html">Wise Care 365</a> , defraged and rebooted and the script magically worked again.

The haters are going to love me now.

<font color="Orange">Edits</font>

Cleaned up some code.

Added error catch.

Added immediate landing option, example - KMun(75,"il","il"), quotes are required.

And, after having my ship topple over for no apparent reason, added stabilization.

Update zip file

A few questions:

First, is there a better documentation link? It seems to be missing the concatenation operator, as well as things like the wait() function (i.e. wait(function() return (vessel.altitudeASL <= 75000) end ), per the Shuttle Autopilot Library by olex. In particular, Wait and Warp to seem to be absolutely critical, and I'd like to know how to control waits and warps other than Pe, Ap, and Sol.

In particular, how can I Warp to just after a certain point in orbit (say, the point as far from KSP as is possible?

FlyMeToTheMun is a good start, but when I tried FlyMeToTheMun(35,35), and once in Munar orbit, the LandTo doesn't appear to be warping ("Cannot warp faster than 1x while the ship is under acceleration"). My orbit is Pe 200836 Ap 200986km Inclination 1.25 Semimajor Axis 400.870km, LAN 145.36, LPe <varies wildly). Stock parts except for MechJeb 1m on top of the 1 kerbal capsule, plenty of fuel left, and I'm at the "Landing" step. EDIT: Just as I posted, my rocket apparently hit the right orbital point, and began its inclination change burn. Still, I'd much rather it have "cut acceleration" and warped.

The reference does not mention concatenation because it is a feature of Lua, the language the scripts are written in, not Autom8. A guide to using Lua can be found here: http://www.lua.org/pil/

[Nadrek]

Thank you for the reference; if I'd seen that Lua guide in the Autom8 wiki, I would have read it.

Is there a trick to using C functions inside Lua with Autom8, per:

http://stackoverflow.com/questions/1034334/easiest-way-to-make-lua-script-wait-pause-sleep-block-for-a-few-seconds

?

[mager42]

How is meaning of this numbers /mechjeb.attitudeTo({0,0,0,0}, "ORBIT")/

If i put anything to second place example- /mechjeb.attitudeTo({0,0.2,0,0}, "ORBIT")/ shutle aim straigth up.

I want set somethhing about 20 degrees pitch.

You can't use C functions is the Lua console directly. If all you want to do is to pause the script for a given time, use the provided wait(ms) function.

How is meaning of this numbers /mechjeb.attitudeTo({0,0,0,0}, "ORBIT")/

It's a quaternion, look it up here: http://en.wikipedia.org/wiki/Quaternion

Setting them manually is tricky and is actually not recommended. For a manual pitch setting, you cann pass a 3-dimensional vector instead of the quaternion - I only used a direct quaternion there because I needed to turn the ship wings-level, too.

I'm not gonna lie but non of this ever works for me can someone give me a step by step on flymetothemun!

There is a step-by-step in the first post. What exactly doesn't work for you? We can't help you not knowing the issue.

Can't make this any easier.

[Leon_Brooks]

looking forward to more scripts from you,togfox. I use the ones you posted quite often.

[mager42]

There is my script for get HTOL spaceplane with atmosferic and clasic engines to orbit.

It is need to manualy start end shut down engines due to i cant turn off Ascent Autopilot staging.

[FlexGunship]

Is there a function to enable or disable RCS?

[Jontu]

I'm trying to access vessel.Longitude but I get an exception. It says "Cannot get Longitude from MuMech.VesselState. Is this not implemented yet? Can I get longitude somewhere else?

Thanx

[togfox]

There is my script for get HTOL spaceplane with atmosferic and clasic engines to orbit.

... i cant turn off Ascent Autopilot staging.

mechjeb.autoStageDeactivate()

[mager42]

I try it but not work for Ascent Autopilot, and even not work mechjeb.stage() when ascent autopilot is active /i try power up main engine during fligth/.

But is not big problem even if that working i cant deactivate jet engines by autom8 so there is still something needed control manualy.

[togfox]

so if I enter the line

mechjeb.attitudeTo({0,0,0}, "ORBIT")

where exactly will that take me to and does it matter on my current soi? Is 0,0,0 relative or absolute? Relative to what?

[togfox]

My script file is attached for those that like my methods. Can't say I did it all on my own though.

File is v1.0 and says so inside the script. File has a .txt name so the forum can accept the attachment. Save to PC and remove the .txt.

type

dofile("orbitops")

full instructions displayed.

The heading you enter is always relative, and it's relative to the second argument, in this case "ORBIT" meaning relative to your orbital prograde heading. Check the wiki for other possible values - you can enter headings relative to orbit, surface, absolute world coordinate system, target vessel/body, and a few more things.
