How does ModuleEngines' List<Propellants> work in the editor?

[ialdabaoth]

Somehow, ModuleEngines manages to create a List<Propellants> that gets loaded from the part.cfg file, and this List<Propellants> is successfully copied from the part in VAB's PartLoader.LoadedPartsList into the part that gets created to stick on your ship in the editor.

I cannot replicate this behavior in my own modules. I've done everything Mu presented in this thread, but when I click on my part and add it to the ship, my List<FuelTanks> is empty. I have confirmed that my List<FuelTanks> in PartLoader.LoadedPartsList has multiple entries, but none of them get copied to the new part. I have also confirmed that ModuleEngines' List<Propellants> DOES get copied correctly in the editor, so clearly what I want to do is possible.

Help?

I've just had a thought, we may be able to stop the list being destroyed by using DontDestroyOnLoad.

Tried it. referencing the part and partmodule's GameObject doesn't work, because the editor-part isn't at all the same part as the launchpad-part.

The ship gets rebuilt from a temporary save file on the launchpad, so all you'd succeed in doing with DontDestroyOnLoad is having parts floating somewhere that never get cleaned up, leading to a memory leak.

I meant use it on the List object rather than the entire part.

Same problem - you now have a list that isn't attached to anything.
