Detailed Description

The following vehicle functions can be used to to control a physX vehicle, either created from an action or from script.
Some commands can be used as setup functions, or others can be used as Control functions in most situations.
Use as vehicle.function()

create a new scripted vehicle to work on. It will need setup with the correct functions.

Order of scripted vehicle creation

  • spawn entity or use entity in scene.
  • call vehicle.createVehicle function to create a new base vehicle.
  • Call setup commands like addChassis, addWheel, setWheelMesh.
  • create the vehicle physics body with vehicle.createPhyicsBody( vehicleID);
  • create the wheels physics with vehicle.createWheels( vehicleID );

Note: this function should be called first before any other vehicle setup commands.

Parameters
vehicleName: The name of this vehicle. it must be unique.
sceneEntityID: The ID of the sceneEntity you wish to make into a vehicle.
posX: Set the position Axis X of where to place the vehicle.
posY: Set the position Axis Y of where to place the vehicle.
posZ: Set the position Axis Z of where to place the vehicle.
rotW: Set the Orientation of the vehicle on the W axis.
rotX: Set the Orientation of the vehicle on the X axis.
rotY: Set the Orientation of the vehicle on the Y axis.
rotZ: Set the Orientation of the vehicle on the Z axis.
Returns
vehID The following is a Small Example on how to use this function: 
function onInit(objID)
    vehID = vehicle.createVehicle( "vehicleName", obj, 0, 0, 0, 0, 0, 0, 0);
end
void vehicle::createWheels ( int  vehicleID)
void vehicle::decelerate ( int  vehicleID)
void vehicle::destroy ( int  vehicleID)

Destroy and cleanup a vehicle in the scene by the vehicle ID passed through this function You should only destroy id's that are active in the scene.

The following is a Small Example on how to use this function: 

function onInit(objID)
    vehID = vehicle.destroy( vehID );
end
void vehicle::enableAutoMaxSteer ( int  vehicleID,
int  state 
)

Sets the steering to auto adjust based on speed and reduce the steering angle.

Parameters
vehicleID: The ID of the vehicle.
state: 1 = true, 0 = false

The following is a Small Example on how to use this function: 

function onInit(objID)
    vehicle.enableAutoMaxSteer( vehID, 1 );
end
void vehicle::followPath ( int  vehicleID,
string  pathName,
float  throttle 
)

follow a path simply by calling this function in an update loop.
The movement will automatically be smoothed out based on the setPathAccuracy() accuracy variable.

Parameters
vehicleID: This is the id of the vehicle.
pathname: The path to follow, change the name on the fly to start following another path without position stepping.
throttle: How far the throttle on the car is pressed. 1 - full speed, 0 - no speed This variable already uses timedelta in the system to keep framerate in check.

Here is a Small Example of how to use this function: 

function onUpdate(timeDelta)
    vehicle.followPath(vehicleID, pathName, 5);
end

Yes, thats all thats needed to follow a path accurately and very fast. =)

void vehicle::followPathPosition ( int  vehicleID,
float  x,
float  y,
float  z 
)

Override the default path follow and enter your own point to move to.
In order for this to take effect, you need to pass a "" in the follow path function. See the example below.

Calling this function on its own will result in nothing happening, it has to be used in conjunction with vehicle.followPath()

Parameters
vehicleID: This is the id of the vehicle.
x: This is the x world position axis. Is defined as a float
y: This is the y world position axis. Is defined as a float
z: This is the z world position axis. Is defined as a float

Here is a Small Example of how to use this function: 

function onInit(objID)
    vehicle.followPathPosition(vehicleID, posArray[0].x, posArray[0].y, posArray[0].z );
end

function onUpdate(timeDelta)
    if(vehicle.isDestinationReached(vehicleID) == 1)then
        posIndex = posIndex + 1;
        newPos = newType.vec3(posArray[posIndex].x, posArray[posIndex].y, posArray[posIndex].z);
        vehicle.followPathPosition(vehicleID, newPos.x, newPos.y, newPos.z );
    end
    
    vehicle.followPath(vehicleID, "", 5.0f); -- set path blank as you do not need one.

end
int vehicle::getActiveVehicleID ( )
int vehicle::getAutoMaxSteerEnabled ( int  vehicleID)

Gets whether the steering angle auto reduces based on speed.

Parameters
vehicleID: The ID of the vehicle.
Returns
isEnabled : This is 1 or 0 value for true or false

The following is a Small Example on how to use this function: 

function onInit(objID)
    isEnabled = vehicle.getAutoMaxSteerEnabled( vehID );
end
int vehicle::getCurrentGear ( int  vehicleID)
float vehicle::getCurrentThrottle ( int  vehicleID)
