Delta-V

[hugopeeters]

Delta-V is not calculated and sent to the controller. Should be possible to loop through all the parts on the vessel to get the mass. An alternative way would be to rely on a different mod to do the calculations, but I would prefer not to depend on other mods.

For what it's worth, I've had a long standing wishlist item to remove most of the calculations, and instead integrate with VOID. My take on it is that avoiding duplication of effort (both in writing code, and in execution time with multiple plugins running their own code to do the same thing every update) is a bigger win.

The game (as of 1.8?) calculates the d-V of each stage. I don't know if that information is available through the API.

Edit: Okay, that was surprisingly easy to find. ShipConstruct objects have a property named vesselDeltaV. That's an instance of VesselDeltaV, which seems to contain all of the relevant information.
