About those grabbing claw devices…

[TIMEFORSPACEPEOPLE]

Hello hello. So about these things, are they similar in some ways to docking ports? Like can they exchange fuel with another ship once you latch on to one with them? Just curious.

Two ships become one.  Resources (including kerbals) may be exchanged.  (I have my "difficulty level" set at: Fun & Imagination.)

Oh cool, thanks!

kerbals can always be exchanged. As for fuel, it depends on the difficulty level. At normal, it can be exchanged. Any higher, it cannot.

The claw does not allow fuel crossfeed, while a docking port does. If your engine was on one ship while your fuel was on the other, it won't work. (It's like a decoupler; engines below the decoupler can't drain tanks above it)

Fuel transfer is different from fuel crossfeed. That's dependent on the difficulty level, as said above; look for the "Resource transfer obeys crossfeed rules" option in the settings. This lets you move fuel from one tank to another through the right-click menu.

Difficulty settings affect this, but if you’re playing on a difficulty which doesn’t allow transferring fuel etc. then you could always send an engineer up to attach a fuel line via EVA construction and pump the fuel that way.
