Question to Devs: What do NozzleLength and NozzleRadius in Porpulsion.xml do?

@AnotherFireFox I missed your previous comment, sorry about that. I was wrong, actually NozzleRadius is used in flight calculations to calculate exit area. NozzleLength is not. It's only used in mass calculation. The game does not detect mesh and auto-calculate dimensions. There is a script that we attach to rocket engine parts, EngineComponentScript, that defines the size of the mesh that is used to calculate collider dimensions. Sorry about that. I should have looked more closely last time.

@AndrewGarrison What I meant was a user-modded nozzle, not stock resizable nozzle, if it wasn't clear. I can understand if you implemented some complicated calculations to deal with the stock resizable nozzles. However with a user-modde nozzle I can't understand. Does the game detect model mesh and calculate dimensions?

@AnotherFireFox they are extrapolated. It’s a bit more complicated.

@AndrewGarrison then how the game determine the nozzle length/diameter with custom nozzles?

Those params aren't used in any flight calculations. They are used in the calculation of the mass of the nozzle and its collider size.

@NoIDontWanna I apologize if I sound rude. I'm currently writing some mods so I need exact equation or at least something similar to that. I might be able to find the information by decompiling the game source, but having some clue would be greatly helpful.

@NoIDontWanna I want to know how the game works. I know real life physics to some degree
