Wheels

[linuxgurugamer]

I'm working on updating an old mod for 1.2.  So far it's mostly working, except for two parts.

These parts are truck bases, and each one has two wheels, one on each side.

Here is the old code from the cfg file (I've commented it out in the file):

//	MODULE
//	{
//		name = ModuleWheel
//		hasMotor = true
//		resourceName = ElectricCharge
//		resourceConsumptionRate = 0.7
//		canSteer = true
//		controlAxisType = Forward
//		steeringModeType = AutomaticSteer
//		brakeTorque = 35
//		brakeSpeed = 0.1
//		impactTolerance = 800
//		overSpeedDamage = 50
//	
//		WHEEL
//		{
//		    wheelName = wheel
//		    wheelColliderName = wheelCollider
//		    suspensionTransformName = suspensionTraverse
//		    suspensionNeutralPointName = suspensionNeutralPoint
//		    damagedObjectName = BustWheel
//		    rotateX = 1
//		    rotateY = 0
//		    rotateZ = 0
//		}
//		WHEEL
//		{
//		    wheelName = wheel001
//		    wheelColliderName = wheelCollider001
//		    suspensionTransformName = suspensionTraverse001
//		    suspensionNeutralPointName = suspensionNeutralPoint001
//		    damagedObjectName = BustWheel001
//		    rotateX = 1
//		    rotateY = 0
//		    rotateZ = 0
//		}
//		steeringCurve
//	 	{
//	   	 key = 0 20
//		 key = 10 5
//	  	 key = 30 2
//		 key = 50 1
//	 	}

When I tried to add 2 ModuleWheelBase modules, I get the following error:

Can't add 'KSPWheelController' to KSCTruckAxleNarrowComplex because a 'KSPWheelController' is already added to the game object!
A GameObject can only contain one 'VehicleBase' component.
 
(Filename:  Line: 97)

NullReferenceException: Object reference not set to an instance of an object

  at UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress) [0x00000] in <filename

Since I can't add two ModuleWheelBase modules, is there any way to control the two wheels, or are these parts dead and unrecoverable?

Also, if someone could point me to the wheel documentation, that would be helpful.

 

Thanks in advance

Stock wheel modules absolutely will not support multiple wheels.

Your only option is to split the wheels into separate part(s); might need one each for left and right wheels.

 

On a related note, I'm still working on getting a replacement wheel-collider solution implemented that -will- allow for multiple wheels/legs/etc in a part, and remove all of the rigidbody orientation constraints from wheels; sadly still likely a few weeks/months out.  (See the KerbalFoundries thread for more info / updates)
