Attaching things in subassembly loader?

[Skorpychan]

I installed the mod, and now can't stick my mun rover onto the lift rocket. It won't become solid and stick on with the green spheres.

I've copied the .craft file straight over into the subassemblies folders. Is that how it works?

If you load something from the subassambly, you can only attatch it to something else at the root of the craft.

The root is the part you started with.

So you might need to rebuild the rover, or the rocket. I'd rebuild the rocket, since you can reuse the rocket for different crafts

I don't believe so, which version are we talking about here?

Is this the new version or the patched Deadbeef version? Because that's not true for the latter.

v0-1-2, according to the .zip file.

If he means the root of the subassembly rather than the main craft, it was still true for the patched Deadbeef version, and something that people complained about regularly.

That's what I mean yes.

And I imagine it'd be very dificult to work around, as you basicly pull 1 gigantic part out of the loader. So you can't have every single possible connection point out already. Also I think the tree build mechanism of this game basicly means you have no other option

There's plenty of space available. It just won't snap to any of it.

AHA

It'll only snap to the root of the subassembly! That's what I was doing wrong. Durp.

Sorry I didn't make that more clear, but yes, that's what we were discussing. Basically, a craft in KSP is a tree of parts. When you attach a part to a craft, the part you attached the part to becomes that part's parent, so the attachment doesn't create a symmetrical relationship. Because of the tree structure, while several parts can share a single parent, each part can have at most a single parent part. A side effect of this is that any craft can only have a single node that has no parent, as there's no way to create a tree that has two "root" parts.

So, when you're trying to attach a subassembly, with or without any of the mods or versions of mods that do this, you can only attach a subassembly by its root piece, because that's the only part of the subassembly that doesn't already have a parent. It would be theoretically possible to restructure the subassembly to change what piece is its root, allowing you to use any of the attachment points present, but that has proven to be more difficult than it sounds, and I'm not sure if it would be possible for a mod to decide which node you're trying to use and rearrange the subassembly in response.
