Action Group Activation

[KerbOrbiter]

Is there a method to activate action group? Something like this:

void actionGroupActivate(string name);

[Michael Kim]

Vessel.ActionGroups.SetGroup(KSPActionGroup, bool)

[KerbOrbiter]

Thanks Michael!

âo avoid doing a lot of topics, I'll ask here: is there a method that returns true or false, depending on lightness?

[Michael Kim]

depending on lightness?

What exactly does this mean?

For action groups, you can also use the indexer, and it is { get; set; }

Like this:

Vessel.ActionGroups[KSPActionGroup]

[KerbOrbiter]

I mean that when the part / vessel illuminated by the Sun, the method returns true, and vice versa.

I mean that when the part / vessel illuminated by the Sun, the method returns true, and vice versa.

I'm not sure but I don't think there's a method specifically doing that, since lighting of a part is handled directly to the part model instead of the part as a whole.

I don't have a good idea how to do what you want - it would require some knowledge on Unity Engine - but I did find something that might be helpful: http://docs.unity3d.com/Documentation/ScriptReference/Light.html

[KerbOrbiter]

using System;
using UnityEngine;
using KSP;

public class ModuleAutomatedLight : PartModule
{
	bool isActive;

	public override void OnAwake()
	{
		Debug.Log("Part with ModuleAutomatedLight succesfully loaded.");
	}

	public override void OnUpdate ()
	{
		isActive = false;
		if (isActive == false && FlightIntegrator.underDirectSunlight == true)   //error!
		{
			Vessel.ActionGroups.SetGroup(KSPActionGroup.Light, true);   //error!
			isActive = true;
		}else if (isActive == true && FlightIntegrator.underDirectSunlight == false)   //error!
		{
			Vessel.ActionGroups.SetGroup(KSPActionGroup.Light, false);   //error!
			isActive = false;
		}
	}
}

Mono returns 4 errors to me. I did not write errors because MonoDevelop wrote them in Russian. Why, I do not know.

[Michael Kim]

Oh man...

I wrote "Vessel" because it's the class name. You need to use the object. Should be "vessel" here

Same with FlightIntegrator, it is a class. The object should be (haven't tried) vessel.flightIntegrator

I would suggest you learn more about C# before writing a plugin. And get an English version of C# compiler so that you know what happens when you get an error.

[KerbOrbiter]

Thank you again! I'm just doing this plugin at leisure using my Java knowledge and a bit of knowledge about C #, so I'm now just learn the language.ÑÂ

I know what compiler writes me, I'm just talking in Russian.

Hi everybody

For some time, I have wanted a "solar wind sail" for deep space missions, but in my attempt to create it (by extending ModuleDeployableSolarPanel), I have ran into the problem, that KSP won't allow me to modify the ships speed when warping is active, neither through directly modifying rigidbody.velocity or by rigidboyd.AddForce.

The solar sail should barely produce any force, so any speed change would be very slow.

Does anyone have any suggestions, except not warping?

Best regards

Perhaps you can do some maths with the orbit. Never tried myself, so don't ask me how to do it, but I think you may find the source code of HyperEdit interesting

AFAIK all rigidbodies whithin a vessel will be kinematic while timewarping (except if you use physics timewarp), hence physics will not be applied to the vessel while timewarping.

You could possibly modify the orbit directly. You could calculate acceleration from the vessel mass and whatever force the sail should apply.

I quickly threw together a small proof of concept plugin, you can view the source here.

Since the sail wont be generating power, you don't need to be running all the stuff in ModuleDeployableSolarPanel, so I just extended ModuleAnimateGeneric and did the obstruction detection and area-facing-the-sun calculations myself.

Note that the plugin I've linked is very much something I threw together, I haven't tested it in-game, so it might very well have some bugs, and modifying the orbit velocity in the way I've done was just an idea, I don't really know whether it will work or not (it might be entirely impossible or, more likely, something different/more needs to be done with the orbit). Maybe you'll be able to get a couple of hints from the HyperEdit source.
