0.15 Landing Gear

[mossman]

The cfg file for the new landing gear that made it in the 0.15 update has no option for adjusting braking torque. However, the way I understand how the cfg files work, they simply modify any existing public variable in the part\'s respective code. How could I obtain the specific variable name to modify, however? I\'ve no experience at all with decompiling code, which makes that particular avenue somewhat daunting for me. Does anyone know the name for that specific (braking torque) value?

[Cykyrios]

Yes it does:

breakingForce = 50

breakingTorque = 50

C7 said he wanted us to be able to easily modify any parts, so he made this

EDIT (\'cause there\'s no point in posting): My bad, didn\'t read correctly >.<

There\'s a different between \'break\' and \'brake\'. Those values modify what it takes to destroy the part.

The line is currently missing, C7 is going to add it, see here.

If we knew the missing line we could add it now ourselves.

Yes, I know, that\'s what the basis for the OP here is. What I\'m asking here is if anyone\'s decompiled the code and looked into seeing what the syntax for the braking-force variable is.

[sal_vager]

Try this line from the cart mod, maybe it\'s the same as KSP uses? C7\'s old part uses the same line.

brakeTorque = 2.5 (this is the carts value)

[mossman]

No, that doesn\'t seem to do the trick.

[sal_vager]

What values did you try? Tosh\'s cart uses 2.5 and even that seems too much.

[mossman]

What values did you try? Tosh\'s cart uses 2.5 and even that seems too much.

The values I tried are irrelevant, because the ones I did try had no effect on how the wheels behaved, thus brakeTorque is not the correct name for the variable (it didn\'t work).

Ask and ye shall receive

Anything in the public namespace is able to overridden in the part.cfg files. So you can completely adjust the handling of the gear, down to frictions and braking forces. So have fun. Just make sure you exactly match case, or it will not work. brake != Brake

  

  public string gearObject = 'DamperCylinder';
  public string wheelObject = 'Wheel';
  public string suspensionObject = 'ShockCylinder';

  public float suspensionExtensionLimit = -0.3512708f;

  public float deployedDragMin = 0.7f;
  public float deployedDragMax = 0.7f;

  // Wheel Traction Behavior / Friction Controls (f) forward, and (s) sideways values

  public float retractedTime = 1f;

  public string brakeKey = 'b'; // key that controls brakes on the gear
  public GearStates gearState = GearStates.DEPLOYED; // starting state of the gear
  public GameObject Gear;

  public float wheelRadius = 0.18f; // Wheel radius
  public float suspensionDistance = 0.7f; // suspension distance
  public float suspensionSpring = 1000f; // suspension spring rate
  public float suspensionDamper = 25000f; // suspension damper
  public float suspensionTarget = 0f; // suspension target

  public float BrakeTorque = 100; //Landing gear brake Torque

  public float MaximumSteeringAngle = 2; // Steering amount
  public float WheelMass = 1.0f; // Wheel mass

Thanks Just one thing I\'d like to know though, is there a way to make the brakes only activate on rear mounted wheels?

Nosewheels aren\'t known for having brakes on airplanes, mainly because they can\'t handle the weight.

[C7Studios]

You would need to make an alternate part and part.cfg file for the nose gear. Then set the BrakeTorque to 0. Should work just fine.

[thorfinn]

Very nice, C7, but I don\'t understand the braketorque and the 'extremum', 'asymptote' etc. values (all the traction block, actually)

I was expecting just the three friction coefficients (static, dynamic and rolling)

[sal_vager]

Zero BrakeTorque front wheels does work, cool, makes it hard to share the designs that use it though.

But another thing I just found which I don\'t think has come up before, is that the wheels still work fully when retracted, I wanted a smaller wheel for the tails of aircraft and now it seems I can use the new stock wheels for this, all I have to do is retract the ones on the tail

Thanks C7.

Ps, is there any way to make two rudders/ailerons split to act as airbrakes?

[mossman]

Yes, this is exactly what I wanted. Many thanks C7.

[Cykyrios]

Sorry for the confusion mossman, I misread your OP >.<

And thank you C7 for these! So we just have to copy/paste those lines in the part.cfg?

And a little question that goes along the same idea: how do I setup the part.cfg to make a part multi-module? I guess that\'s what Mu explained in one of his posts, but I\'m not really sure.

[Charzy]

Would it be possible to get longer landing gear for bigger planes?
