[1.1.2] Kerbal Attachment System (KAS) 0.5.8

Recommended Posts


Last updated 12 June 2016 - v0.5.8 for KSP 1.1.2

KAS introduces new gameplay mechanics by adding winches and eva attachable struts/pipes. It gives some purpose to EVA and can be used for many things:

  • Resource transfer
  • Towing parts
  • Base/vessel interconnections
  • Vessel consolidation
  • Cranes
  • Airship anchoring
  • Skycranes
  • Elevators
  • ...and more

! Important note !

Since KAS v0.5.4, KIS is no more mandatory (only highly recommended).

However by using KAS without KIS, take note that you will not be able to :

  • Attach/detach connectors from EVA
  • Store hooks in containers
  • Mount hooks on winches from EVA
  • Attach hooks from EVA
  • Attach ground pylon on the ground

To get all this features, You need to install KIS. You can download it here.

Notes for user upgrading from KAS 0.4.X

As KAS v0.5 now use KIS and KSP 1.0 is out, I took some time to reduce the part count by removing/merging some parts.

To avoid loosing a ship because of a missing part, you can download old parts from KAS v0.4 from the curse mod page.

The old parts will still work, but I will not maintain them, so I recommend to trash them.

Here is some methods to safely trash them :

  • Put them in a container (missing part will be ignored after part removal)
  • Let them alone on the ground or in orbit
  • Destroy old parts with the new KIS explosives :)

This old parts will not be available from the editor, so if you want to continue to use them, you need to change the line "category = none" to "category = Utility" in the corresponding cfg file.

Hello, i'm trying to add the KASModuleGrab on KAS_ContainerBay. it' works (I tried 2 ways. via addModule.cfg and editing the cfg part file), but it attaches behind the surface. I mean, half of the mesh is hidden inside the part or ground. I don't see any surface distance code or attach z position (only EVA) to fix this. I've tried changing the node name. but no changes.

Any idea how to fix this?

this is the code i'm using (addModule.cfg):

///////// KAS_ContainerBay1 ///////



stockPartName = KAS_ContainerBay1

evaPartPos = (0.0, 0.40, -0.10)

evaPartDir = (0,0,-1)

attachNodeName = bottom

attachOnPart = True

attachOnEva = False

attachOnStatic = True

attachSendMsgOnly = False

I hope I didn't miss something with the fix. It's been a while since I did not touch the source code !

Keep me informed if something else is broken on the x64 version. I can't play a lot right now...

Also, the changelog for v0.4.8 :

- 0.24.2 compatibility

- Fixed explosions when grabbing a part with x64 version of KSP

- Fixed kerbal teleportation to zero velocity when grabbing a part in space (ex : orbiting moon)

- Fixed NRE when grabbing a stateful part from a container (Thanks to Angavrilov)

- Some Spelling/grammar fixes for part descriptions (Thanks to Dennovin)

KospY: awesome! Glad things are going ok and you had a chance to pop back on here for a bit!

One problem, though: <mod hat on> due to the new addon rules, the zip file also needs to contain a copy of the license or, if it's a common one like CC-* or LGPL, a reference to it. </mod hat>

Thank you :)

I didn't know for the licence, I uploaded a new version with it.

YAY! So to confirm, we can just download it above and everything should more or less work now, regardless of our version, right? No other fixes needed? (again, with only perhaps minor hiccups, but nothing game-breaking?)

It should work as before on 0.23 at least :) If not, keep me informed.

Hopefully this will fix the problems I was having last night on the Win32 version. Trying to put some mono tanks onto a ship in orbit. Got two placed but then it acted up on the third. Saving and reloading sorted it out for that but not for the 4th one. Didn't try quitting and restarting KSP, was nearly 4 AM by then.

Bob was sliding down the ladder (instead of staying put) and after pulling the tank from the bin it would drift away. Could attach it to the ship but it was also still attached to Bob, same right click menu with it on the ship as with it on Kerbalback.

From there the route was either an explosion or strange forces twisting the ship apart.

Will test the new release tonight to see if I can get the other 5 tanks mounted.

I am getting an error with KAS now that I have the newest upload and it is saying that it is incompatible with the 24.2 version of KSP. Any idea why? It is also triggering on the KSPAPIextensions and aaa_Toolbar as well all for the same thing.
