How to get ship and ship Delta-V in VAB/SPH?

I've been tearing my hair out over this for the past 2-3 days. I'm currently making a simple mod that calculates if a flight is possible given current delta-v's. However, I cannot figure out how to get the delta-v's of a ship in an editor, nor able to even get any sign of a ship being detected.

I think it has to do with ShipConstruct, but I can't figure out how to get current vessel as a Ship. It could also be Vessel that handles editor, but I found nothing suggesting that to be the case. I've skimmed through the class index on the API site, and found nothing.

Does anyone know about this? I'm very new to C# modding.

Take a look at @DMagic's Basic DeltaV - along with MechJeb and Kerbal Engineer code. All these mods (IIRC) have their source code on GitHub. SpaceDock and Forum threads usually have links. Good Luck!

Subscribe to the DeltaVCalcsCompleted event to be notified every time the user changes the ship:

GameEvents.onDeltaVCalcsCompleted.Add(OnDeltaVCalcsCompleted);

In that event's handler, you can get the complete delta V analysis from EditorLogic.fetch?.ship?.vesselDeltaV:
