spinning wheels?

[Almeida 12]

Greetings!

Im developing a car for arma 3. I'm having trouble to make the wheels spin. Thanks for any help.

heres the animation in model.cfg:

class Wheel_1_1

{

type="rotationX";

source="wheel";

selection="wheel_1_1";

axis="wheel_1_1_axis";

memory=1;

sourceAddress="loop";

minValue=0;

maxValue=1;

angle0=0;

angle1="rad -360";

};

#1 Make sure you have this at the top of your model.cfg

class Rotation
{
type = "rotation";
memory = 1;
minValue = 0;
maxValue = 1;
angle0 = 0;
angle1 = 1;
};

#2 Make sure your PhysXLOD is completely correct. Named selections. Spelling is critical.

You only need this if one of your classes inherits from it

(e.g. class Something : Rotation {}). If no class does, you dont need it.

Woops, forgot about that....

As well read through this.

And remember Download Arma 3 tools from steam, there is samples of A3 Vehicles in there.

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
// General parameters
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

// <Description>: Name of the bone, used for wheel and suspension animations.
// <Type>: string
// <Default>: ""
boneName = "wheel_1_1_damper";

// <Description>: If true, wheel is steerable, false - wheel is fixed.
// <Type>: bool
// <Default>: (required)
steering = true;

// <Description>: Defines if wheel is on the right or left side of the vehicle
// <Type>: string
// <Default>: "right"
side = "left";

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
// Wheel PX parameters
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

// <Description>: Center of the wheel (axis)
// <Type>: memory point
// <Default>: (required)
center   = "wheel_1_1_axis";

// <Description>: Point on the outside rim of the tire, used to calculate radius of the wheel (distance between center and boundary).
// <Type>: memory point
// <Default>: (required)
boundary = "wheel_1_1_bound";

// <Description>: This is the weight in kg of wheel including both rim and tyre.
// <Type>: float
// <Default>: 10.0
mass = 20;

// <Description>: This is the wheel's moment of inertia about the rolling axis. Smaller values result in more slips in aggresive driving
// while larger hamper the gain of speed. Good base to start with is this formula:
// MOI = 0.5 * Mass * Radius * Radius
// Some tweaking is needed after the computation, but it is still better than nothing.
// <Type>: float
// <Default>: 0.5 * WheelMass * WheelRadius * WheelRadius
MOI = 3.3;

// <Description>:The damping rate describes the rate at which a freely spinning wheel loses rotational speed. 
// Values in range (0.25, 2) seem like sensible values. Experimentation is always a good idea, even outside this range.
// <Type>: float
// <Default>: 0.1
dampingRate = 0.5;

// <Description>: This is the value of the torque applied to the wheel when the brakes are maximally applied. Higher torques will lock the wheel 
// quicker when braking, while lower torques will take longer to lock the wheel.
// A value of around 1500 is a good starting point for a vanilla wheel but a google search will reveal typical braking torques. One difficulty is 
// that these are often expressed by manufacturers as braking horsepower or in "pounds inches". The values required here are in "Newton metres".
// <Type>: float
// <Default>: 2500
maxBrakeTorque = 2000;

// <Description>: This is the same as the max brake torque except for the handbrake rather than the brake. Typically, for a 4-wheeled car, 
// the handbrake is stronger than the brake and is only applied to the rear wheels. A value of 4000 for the rear wheels is a good starting point, 
// while a value of 0 is necessary for the front wheels to make sure they do not react to the handbrake.
// <Type>: float
// <Default>: 2*maxBrakeTorque
maxHandBrakeTorque = 0;

// <Description>: This is the direction of the suspension in the downward direction in the rest configuration of the vehicle. A vector that 
// points straight downwards is a good starting point.
// <Type>: Array[3]
// <Default>: {0, -1, 0}
suspTravelDirection[] = {0, -1, 0};

// <Description>: This is the application point of the suspension force.
// <Type>: memory point
// <Default>: center
suspForceAppPointOffset = "wheel_1_1_axis";

// <Description>: This is almost the same as the suspension force app point except for the lateral and longitudinal forces that develop on the tire.
// A good starting point is to duplicate the suspension force application point.

// <Default>: suspForceAppPointOffset
tireForceAppPointOffset = "wheel_1_1_axis";

// <Description>: This is the mass in kg that is supported by the suspension spring.
// <Type>: float
// <Default>: vehicleMass/numberOfWheels
sprungMass = 350.0;

// <Description>: This is the strength of the suspension spring in Newtons per metre.
//   springStrength = naturalFrequency * naturalFrequency * sprungMass
// <Type>: float
// <Default>: sprungMass*5,0*5,0
springStrength = 22600;

// <Description>: This describes the rate at which the spring dissipates the energy stored in the spring.
// Basic equiation for this is
//  springDamperRate = dampingRatio * 2 * sqrt(springStrength * sprungMass)
// where dampingRatio = 1 mean critical damping (critically damped pendulum should get back to start point in every swing)
// <Type>: float
// <Default>: 0,4*2*sqrt(springStrength*sprungMass)
springDamperRate = 8680;

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
// Tire parameters
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

// <Description>: Increasing this value will result in the tire attempting to generate more longitudinal force when the tire is slipping.  
// Typically, increasing longitudinal stiffness will help the car accelerate and brake. The total tire force available is limited by the 
// load on the tire so be aware that increases in this value might have no effect or even come at the expense of reduced lateral force.
// <Type>: float 
// <Default>: 10000
longitudinalStiffnessPerUnitGravity = 100000;

// <Description>: These values together describe the lateral stiffness per unit lateral slip (in radians) of the tire.
// <Type>: float, float
// <Default>: 25, 180
latStiffX = 25;
latStiffY = 18000;

// <Description>: These six values describe a graph of friction as a function of longitudinal slip. 
// A good starting point for this is a flat graph of friction vs slip with these values:
// frictionVsSlipGraph[0][0]=0.0
// frictionVsSlipGraph[0][1]=1.0
// frictionVsSlipGraph[1][0]=0.5
// frictionVsSlipGraph[1][1]=1.0
// frictionVsSlipGraph[2][0]=1.0
// frictionVsSlipGraph[2][1]=1.0
// <Type>: Array[3][2]
// <Default>: {{0, 1}, {0.5, 1}, {1,1}}
frictionVsSlipGraph[] = {{0, 1}, {0.5, 1}, {1,1}};

Thanks for the tips guys.
