Asteroid Warning Plugin.

[Robotengineer]

This should be a simple plugin that stops time warp and delivers a message that there is an imminent impact to Kerbin. I have little programming experience, and help would be be appreciated. I have done some looking around and should have a prototype soonâ„¢. My current idea of how the plugin will work is it will get the vessel type, determine if that vessel is a space object. Then get the Kerbin periapsis of the Vessel. If anything is in error with that idea please tell me and I will try to correct it.

Like idea, but there currently aren't any asteroids that interact with kerbin SOI, right.........?

I believe that for asteroids to spawn in stock, they have to have a Kerbin intercept.

I don't think this is true.

Believe such a mod may be really helpful.

Of course every game is different, but... with 0.23.5 I started a new career game, and the first three asteroids (C, C, and D class) to enter Kerbin's SoI were all going to hit (and all within 2 days). And, I only knew when they actually entered the SoI, what info I got with initial discovery wasn't giving any close pass. An early warning of such dangers would have made it somewhat easier (I could just about catch them and save Kerbin).

If I may suggest, could you consider making some references to B612 in your mod? B612 has exactly the same purpose in reality, and its reps have often shown interest with KSP.

Thanks, as it is I am going to be learning C# as I make the plugin I will probably not be able to make it to complicated. I am not sure if it is possible to get the periapsis of a vessel if it is not in the SOI of Kerbin, I.E. get the periapsis of an asteroid for Kerbin, when it is in orbit around the sun. And any help in development of this would be greatly appreciated. This is what I have so far.

using System;
using UnityEngine;
using System.Collections.Generic;

namespace Asteroid_Warning
{
	public string type
	public bool isAsteroid
	public double periapsis

	public class asteroidWarning
	{

}

Not much.

I don't know if you already use this mod: PreciseNode. It has the ability (among many other things) to predict the periapsis that occurs in a conic patch after the current one for the active vessel (after a SoI change). Its sourcecode is available (almost all written by regex!) and you will certainly learn a lot from it.

I will check it out, I don't use it currently as I typically don't use nodes that much.

Ok, did some looking into linq and other things. I now have an idea for how it will work.

heres the idea for the flow of the plug-in.

 AllVessels --> Vessels.SpaceObject --> Asteroids that enter Kerbins SOI --> Asteroids that have a periapsis < 30,000 --> warning message

This is what I have for code so far.

 using System;
using UnityEngine;
using System.Collections.Generic;
using linq;

namespace Asteroid_Warning
{
	public class asteroidWarning
	{
		List<Vessel> allVessels = new List<Vessels>;
		foreach(VesselType.SpaceObject in Vessels);
		{

		}
	}

Not sure if I should use IEnumerable or foreach or something else. Suggestions on code would be greatly appreciated.
