Multiple Vehicle Wheel problems

#1 In your the .cs file for each vehicle, e.g. car.cs, it specifies what wheel is loaded. I assume you just copied the current file and changed the body to your dts shape.

#2 Nope.

datablock WheeledVehicleTire(BuggyTire)
{
   // Tires act as springs and generate lateral and longitudinal
   // forces to move the vehicle. These distortion/spring forces
   // are what convert wheel angular velocity into forces that
   // act on the rigid body.
   shapeFile = "~/data/shapes/Buggy/wheel.dts";
//
//
datablock WheeledVehicleTire(Redcar)
{
   // Tires act as springs and generate lateral and longitudinal
   // forces to move the vehicle. These distortion/spring forces
   // are what convert wheel angular velocity into forces that
   // act on the rigid body.
   shapeFile = "~/data/shapes/redcar/wheel.dts";

as far as I can tell I did everything right.

#3 Make sure you are using the Redcar datablock when you are creating your redcar model, and you aren't accidentally attaching the BuggyTire to the car instead of your new one.

#4 OK now I see thee is a difference when I chose a different car to spawn mounted in. I use a variable that gets transfered with the client data.

function GameConnection::spawnPlayer(%this)
   {
      // Combination create player and drop him somewhere
      %spawnPoint = pickSpawnPoint();
      %this.createvehicle(%spawnPoint);
   }   

   function GameConnection::createvehicle(%this, %spawnPoint)
   {
      error("inside onNewDataBlock");
      if (%this.vehicle > 0) 
      {
         // The client should not have a player currently
         // assigned. Assigning a new one could result in
         // a player ghost.
         error( "Attempting to create an angus ghost!" );
      }

      %player = new Player()
      {
         dataBlock = PlayerBody;
         client = %this;
      };

      error("created player");

      MissionCleanup.add(%player);
      error("added driver to missionCleanup");

      // player setup
      %player.setTransform(%spawnPoint);
      %player.setShapeName(%this.name);

      %this.camera.setTransform(%player.getEyeTransform());
      %this.player = %player; 
      //%this.setControlObject(%player);

      // Starting equipment
      %player.setInventory(Crossbow,1);
      %player.setInventory(CrossbowAmmo,10);
      %player.mountImage(CrossbowImage,0);

      // Create the vehicle object
      %vehicle = new WheeledVehicle() 
      {
         dataBlock = %this.clientVehicle;
         mountable = true;
         client = %this;
      };

      error("created vehicle");

      MissionCleanup.add(%vehicle);
      error("added vehicle to missionCleanup"); 

      //attempt to mount player 
      error("Attempting to mount player to vehicle");

      %node = "mount0";
      //%this.player.onMount(%this,%player,%vehicle,%node);
      %vehicle.mountObject(%player, 0);
      //%player.Armor.onMount(%this,%player,%vehicle,%node);

      // Player setup...
      %vehicle.setTransform(%spawnPoint);
      %player.setShapeName(%this.name);

      // Update the camera to start with the player
      %this.camera.setTransform(%vehicle.getEyeTransform());

      // Give the client control of the player
      %this.vehicle = %vehicle;
      %this.setControlObject(%vehicle);

      error("leaving racing.game.cs");
   }

Whatever car I select is the car whose wheels are showing up. The body is the same as it should be, but not the wheels.

#5 I may be mistaken but I believe it is because the wheels are not being sent with the vehicle data block. Has anyone dealt with this before and had a solution?

I guess what I need to know is if there is someway to reconstruct the car datablock so that everything (wheels, springs, emitters,..) is contained within the one datablock.

#6 OK my problem lies within my function WheeledVehicleData::onAdd(%this,%obj). It needs to be able to load the correct wheels, springs, or anything else I add on to it based upon the vehicle that the player has chosen.

Let me add some more details. My player spawns with a vehicle of his chosing that he can exit and enter into any other vehicle that is available. The cars bodies are loading just fine. However, anything that is not within the vehicles primary datablock is being set to what ever the individual client had slected for their vehicle.

Help!!

#7 OK I came up with a solution that works very well. It also allows lots of other customizations.

First I created a vehicle.cs file to keep functions universal to all vehicles and added:

function WheeledVehicleData::onAdd(%this,%obj)
{
   // Setup the car with custom tires & springs
   %obj.setWheelTire(0,%this.RFTire);
   %obj.setWheelTire(1,%this.LFTire);
   %obj.setWheelTire(2,%this.RRTire);
   %obj.setWheelTire(3,%this.LRTire);
   %obj.setWheelSpring(0,%this.Spring);
   %obj.setWheelSpring(1,%this.Spring);
   %obj.setWheelSpring(2,%this.Spring);
   %obj.setWheelSpring(3,%this.Spring);
   %obj.setWheelPowered(0,false);
   %obj.setWheelPowered(1,false);
   
   // Steer front tires
   %obj.setEngine(CarEngine);
   %obj.setWheelSteering(0,1);
   %obj.setWheelSteering(1,1);

   // Only power the two rear wheels...
   %obj.setWheelPowered(2,true);
   %obj.setWheelPowered(3,true);

}

#8 Then in each of the vehicle's *.cs files I did this:

datablock WheeledVehicleTire(CarRFTire)
{
   // Tires act as springs and generate lateral and longitudinal
   // forces to move the vehicle. These distortion/spring forces
   // are what convert wheel angular velocity into forces that
   // act on the rigid body.
   shapeFile = "~/data/shapes/car/wheel.dts";
   staticFriction = 4;
   kineticFriction = 3;

   // Spring that generates lateral tire forces
   lateralForce = 18000;
   lateralDamping = 4000;
   lateralRelaxation = 1;

   // Spring that generates longitudinal tire forces
   longitudinalForce = 18000;
   longitudinalDamping = 4000;
   longitudinalRelaxation = 1;
};

datablock WheeledVehicleTire(CarLFTire)
{
   // Tires act as springs and generate lateral and longitudinal
   // forces to move the vehicle. These distortion/spring forces
   // are what convert wheel angular velocity into forces that
   // act on the rigid body.
   shapeFile = "~/data/shapes/car/wheel.dts";
   staticFriction = 4;
   kineticFriction = 3;

   // Spring that generates lateral tire forces
   lateralForce = 18000;
   lateralDamping = 4000;
   lateralRelaxation = 1;

   // Spring that generates longitudinal tire forces
   longitudinalForce = 18000;
   longitudinalDamping = 4000;
   longitudinalRelaxation = 1;
};

datablock WheeledVehicleTire(CarRRTire)
{
   // Tires act as springs and generate lateral and longitudinal
   // forces to move the vehicle. These distortion/spring forces
   // are what convert wheel angular velocity into forces that
   // act on the rigid body.
   shapeFile = "~/data/shapes/car/wheel.dts";
   staticFriction = 4;
   kineticFriction = 3;

   // Spring that generates lateral tire forces
   lateralForce = 18000;
   lateralDamping = 4000;
   lateralRelaxation = 1;

   // Spring that generates longitudinal tire forces
   longitudinalForce = 18000;
   longitudinalDamping = 4000;
   longitudinalRelaxation = 1;
};

datablock WheeledVehicleTire(CarLRTire)
{
   // Tires act as springs and generate lateral and longitudinal
   // forces to move the vehicle. These distortion/spring forces
   // are what convert wheel angular velocity into forces that
   // act on the rigid body.
   shapeFile = "~/data/shapes/car/wheel.dts";
   staticFriction = 4;
   kineticFriction = 3;

   // Spring that generates lateral tire forces
   lateralForce = 18000;
   lateralDamping = 4000;
   lateralRelaxation = 1;

   // Spring that generates longitudinal tire forces
   longitudinalForce = 18000;
   longitudinalDamping = 4000;
   longitudinalRelaxation = 1;
};

datablock WheeledVehicleSpring(CarSpring)
{
   // Wheel suspension properties
   length = 0.73;             // Suspension travel
   force = 3000;              // Spring force
   damping = 600;             // Spring damping
   antiSwayForce = 3;         // Lateral anti-sway force
};

datablock WheeledVehicleEngine(CarEngine) {
   // Default Engine info...
   MinRPM = 500.0;

   throttleIdle = 0.1;

   gearRatios[2] = 1.35;
   gearRatios[3] = 0.97;
   gearRatios[4] = 0.74;
   
   diffRatio = 3.39;
   reverseRatio = 3.60;
   
   shiftUpRPM = 2300.0;
   shiftDownRPM = 1100.0;

   numTorqueLevels = 8;
   
   rpmValues[0] = 500.0;
   torqueLevel[0] = 70.0;
   
   rpmValues[1] = 1000.0;
   torqueLevel[1] = 100.0;
   
   rpmValues[2] = 1500.0;
   torqueLevel[2] = 130.0;
   
   rpmValues[3] = 2000.0;
   torqueLevel[3] = 150.0;
   
   rpmValues[4] = 2500.0;
   torqueLevel[4] = 140.0;
   
   rpmValues[5] = 3000.0;
   torqueLevel[5] = 125.0;
   
   rpmValues[6] = 3500.0;
   torqueLevel[6] = 120.0;
   
   rpmValues[7] = 4000.0;
   torqueLevel[7] = 105.0;
   
   rpmValues[8] = 4500.0;

};

#9 That replaced the spring info and wheel info, oh yeah and I am trying to get a working transmission. heheh.

Remember to change the part like CarSpring and the "Car" labelled wheel datablocks to names for each of your vehicles.

Finally, add this to the bottom of your vehicle's main datablock. Again remember to change the "Car" references for each of your vehicles.

RFTire = "CarRFTire";
   LFTire = "CarLFTire";
   RRTire = "CarRRTire";
   LRTire = "CarLRTire";
   Spring = "CarSpring";

#10 Oh and don't forget to make that vehicle.cs file or what ever you use executed at the game.cs file.

#11 Function WheeledVehicleData::onAdd(%this,%obj)

adds the same tires to every WheeledVehicleData dataBlock, so you just need to change it to something like

function DefaultCar::onAdd(%this,%obj)

where DefaultCar is the name of your vehicle's dataBlock.
