Velocity at a given point

[Teilnehmer]

Is there a plugin showing the vehicle’s velocity at the point the user hovers/clicks on the map?

I’m totally new to making KSP mods. I know C# and I succeeded at modifying some existing mods, but I’m stuck trying to write a new one.

I want to add the orbital velocity value to the ‘Add maneuver / Warp here’ popup window. What should I inherit and override to do that?

I don't think you can ask KSP "what's this ship's velocity at x point in the future"; you'd have to do the math yourself.

Look at the current orbit and speed, then query how far ahead in the future the 'warp to' button is, and then calculate what the ship's velocity would be at that point based on the planet's gravity and your altitude.

I have no idea why this would be useful.

Could be useful for aerobraking maneuvers (at Jool for example).

With a minor modification you could ask KSP what your velocity at a future point is. So long as there are no SOI changes the process is simple. SOI changes make it only slightly harder. Just use energy. Eg = mgh and Ek = 1/2 mv^2. hover over a point on the orbit and it would give you altitude. From that and your current altitude and velocity the new velocity could be calculated. SOI changes require iteration at the point where the change occurs but is still doable.

The Orbit class should already handle all of that, you just need to create a display. If the Orbit class doesn't provide the bit of information you want, just extend it and add the math.
