Airbrake

[Vlad. Just Vlad.]

My first plugin - airbrake. Turns on with 'B' key. It uses the way to activate that similar to the MuMech code.

Will be useful when return from space for additional brake in atmosphere.

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using UnityEngine;

namespace AirB
{
  public class Airbrake : Part
  {
    private bool Active = false; //Toggle bool
    private float on_drag = 5F; 
    private float on_drag_min = 4F;
    private float off_drag = 0.1F; //Drag parameters

    protected override void onPartStart() //Turn off when start
    {
      transform.FindChild('model').FindChild('off').renderer.enabled = true;
      transform.FindChild('model').FindChild('on').renderer.enabled = false;
    }

    protected override void onPartUpdate()
    {
      base.onPartUpdate();

      if (Input.GetKeyDown(KeyCode.)
      {
          if (Active == false) //Turn on
          {
            transform.FindChild('model').FindChild('on').renderer.enabled = true; //Make 'on' model visible, and make 'off' model invisible
            transform.FindChild('model').FindChild('off').renderer.enabled = false;
            maximum_drag = on_drag; //Change drag
            minimum_drag = on_drag_min;
            Active = true; //Change toggle bool
          }


        else //Turn off
        {
          transform.FindChild('model').FindChild('off').renderer.enabled = true; //Make 'off' model visible, and make 'on' model invisible
          transform.FindChild('model').FindChild('on').renderer.enabled = false;
          maximum_drag = minimum_drag = off_drag; //Change drag
          Active = false; //Change toggle bool
        }
      }
    }
  }
}

Sweet! I was waiting for one of these to come around, thanks Vlad!

[zack2014]

So how would we change this to be a different part in the .cfg?

What would the parameters be?

Nevermind, forgot I could look in the cfg file

[Douglasdtlltd]

Why are you making it have drag when it\'s closed? That doesn\'t make sense at all, can you/we change it?

[cardgame]

This looks pretty cool, I\'ll be keeping my eye on it.

[Vlad. Just Vlad.]

I\'m working now on smooth animation.

Why are you making it have drag when it\'s closed? That doesn\'t make sense at all, can you/we change it?

Because every part has drag, even if it\'s between 2 others.

[Majiir]

Very nice. Might I suggest something more complex as a next project?

Many planes are fitted with control surfaces that could be used as airbrakes themselves, if only the game would control them accordingly. Many setups would impart a translation force on the plane, but for some situations this is okay, and some planes could cancel that translation force entirely. The trick is to adjust the control surfaces so that the torque produced isn\'t changed, but a large force is applied to slow down the plane.

[Emilio]

@Majiir I think it could be done by derivating from the ControlSurface class.

Anyway, great mod ! I\'ll use it for slowing down my deep space cargoship

[Volt]

This looks too good. What a great thing to return to after a week in a muddy, cold campsite!

Can\'t download just yet so I must ask: can you change the brake toggle from the \'B\' key?

[Kreuzung]

Nope, it\'s hardcoded.

[Vlad. Just Vlad.]

I can change it, but why? And I should change all plugin.

When I shall understand how to make part rotate around it\'s axis, I\'ll make key binding with part.cfg. I had not thought about it.

[Kreuzung]

Change

Input.GetKeyDown(KeyCode.

to

Input.GetKeyDown(key.ToLowerInvariant())

and add

string key = 'b';

to your params list at the top.

This way, it could be configured in the part.cfg!

[Lazurkri]

This is awesome for my ballistic Minimus return probes! I usually mount just barely enough engines to put them into a return trajectory, but the downside of that sometimes is insufficient thrust to slow down enough for parachutes to slow the ship down; now I can watch my probe hurtle in nose first, pop aerobrakes, and slow down enough to survive landing!

[Vlad. Just Vlad.]

Change

Input.GetKeyDown(KeyCode.

to

Input.GetKeyDown(key.ToLowerInvariant())

and add

string key = 'b';

to your params list at the top.

Thanks, but I knew it

I can\'t make my airbrake rotate around it\'s Z-axis. I\'ll try to make it with Transform.InverseTransformDirection.

I\'m working now on Shuttle airbrake. It will look like Space Shuttle rudder brake, and yes, there will be cuctom key binding And there will also rudder turning.

[Volt]

Yep, tested this out and it is absolutely perfect in terms of crude, basic speed-braking in midair. I can now do diving approaches a la C-130 on KSP! Thank you!

[colmo]

These also perform excellently as landing flaps. Well done.

[theflyingfish]

Drag in KSP is still a little too powerful for these to be very useful. However, in the future when energy management becomes a little more crucial, these will be great.

[TheCarrot]

Hey with the .rar do i put it in the parts or plugins? Thanks

[KAO]

you know, how about we necropost in ALL the dead threads, it seems to be all the rage nowadays

[Festivefire]

He was asking for help. I think that's a little different than necroing "hey guys his sucks!" three months after the last post.

But anyways, after you extract the .rar with winzip or something like it, tere will be a parts folder and a plugins folder. Drop them in your main ksp folder and say yes if it asks you to merge the folders.

[CrashnBurn]

I used this mod in Eve's very dense atmosphere, it seems to work fine in .17.
