How to add parts to a active vessel midflight?

[TheLunaticist]

I'm trying to add parts to a active vessel and have spend quite some time on research.

I only found people recommending reading the KAS/KIS mod github, but I am not able to make any sense of what is done in the mod to add new parts because the mod is split up in so many different text documents which makes it impossible to read for me. (A terrible amateur coder) 

 Could you tell me what it takes to add new parts to vessels? (I don't need a super detailed explantation but a list of requirements or an example would be nice)

Use docking ports for a Stock option.
Use Kerbal Attachment System (KAS) mod to build outside of the editor.

If you prefer a Kludge-fix, create a Module Manager cfg file to add a docking port module to all parts, referencing their attachment nodes.

I believe OP was talking about via code, as in a mod adding parts.

1 - Create an object to contain the transform of the part you wish to attach something to (Transform parentTransform = parentPart.transform)

2 - instantiate the part you want to attach and then make its transform the child of parentPart.transform (childPart.transform.parent = parentTransform)

3 - Be sure to adjust the childPart.transform.localPosition before attaching to the parent transform or things can get 'splodey 

This is just 3 things off the top of my head that you will need to know how to do in order to attach parts in the flight scene ... and there is a bunch of other stuff you will need to know (waiting a couple fixed updates before unpacking so the Kraken doesn't show up, getting the mesh bounds of the parent part, adjusting part orientation, set part temp to a positive value, declaring initial part spawn location, etc..., etc..., etc...)

TL;DR - it's a bit more complicated than writing a few lines of code ... just look at KIS and KAS, more than a few lines of code there
