HOW TO LOAD THE CAR WITH WHEEL

#1 Lots of things wrong with your code.

You need to call something like this in GameConnection::createPlayer

%player = new WheeledVehicle() {
      //dataBlock = %this.playerDB;
      dataBlock = "DefaultCar";
      client = %this;
   };
   MissionCleanup.add(%player);

Also, you should probably buy T3D if you are going to use it.

#2 Here i am giving the proper code.. but still wheel is not loading.please spot error in the code.
