Combining Part Parameters

[njmksr]

Hey everyone!

Does anyone here know how to make a part that draws some of its parameters from the part directly above it?

I'm working on a modular engine mod and I need to know how to pass parameters between the parts.

Thanks!

From within a PartModule you can do: this.part.parent to get the parent part in the hierarchy.

So if you had an engine split between a fuel pump and exhaust bell, would you be able to make the fuel pump determine stuff like isp?

In principle. Real Fuels does this based on chosen settings within the engine part itself but there's no reason you couldn't get your custom engine module to read values from another part instead. You would of course need robust error handling for a case where user forgot to add a needed part to the vessel or tried to configure things out of the intended sequence.

So could I base the plugin off of RealFuels?
