How to make the player a movable RigidShape?

Ok, I'm new here, but I'm making a game for class where I would like the player to be a sphere (yes, somewhat like Marble Blast, but not exactly the same thing). I found the Rigid Shape class and recompiled the engine with that, but now I can't seem to figure out how to modify the base tutorial to use a Rigid Shape sphere for the player instead of that green alien guy. I got it to load the sphere, but hitting the WASD keys doesn't move the sphere around at all. I can pick it up and it will roll away on its own if it's on a slope, but you can't control it.

Here are the only parts of the scripts I've changed:

datablock RigidShapeData(BouncingBall)
{   

   category = "RigidShape";
   
   shapeFile = "~/data/shapes/player/sphere.dts";
   emap = true;

   // Rigid Body
   mass = 500;
   massCenter = "0 0 0";    // Center of mass for rigid body
   massBox = "0 0 0";         // Size of box used for moment of inertia,
                              // if zero it defaults to object bounding box
   drag = 0.2;                // Drag coefficient
   bodyFriction = 0.2;
   bodyRestitution = 0.1;
   minImpactSpeed = 5;        // Impacts over this invoke the script callback
   softImpactSpeed = 5;       // Play SoftImpact Sound
   hardImpactSpeed = 15;      // Play HardImpact Sound
   integration = 4;           // Physics integration: TickSec/Rate
   collisionTol = 0.1;        // Collision distance tolerance
   contactTol = 0.1;          // Contact velocity tolerance
   
   minRollSpeed = 10;
   
   maxDrag = 0.5;
   minDrag = 0.01;

   triggerDustHeight = 1;
   dustHeight = 10;

   dragForce = 0.05;
   vertFactor = 0.05;

   normalForce = 0.05;
   restorativeForce = 0.05;
   rollForce = 0.05;
   pitchForce = 0.05;
 
   computeCRC = true;
  
   canObserve = true;
   cmdCategory = "Clients";

   cameraDefaultFov = 90.0;
   cameraMinFov = 5.0;
   cameraMaxFov = 120.0;
 
   minLookAngle = -1.4;
   maxLookAngle = 1.4;
   maxFreelookAngle = 3.0;

   jumpForce = 8.3 * 90;
   jumpEnergyDrain = 0;
   minJumpEnergy = 0;
   jumpDelay = 15;
   
   minJumpSpeed = 20;
   maxJumpSpeed = 30;


};

And...

function GameConnection::createPlayer(%this, %spawnPoint)
{
   if (%this.player > 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!" );
   }

   // Create the player object
//   %player = new Player() {
//      dataBlock = PlayerShape;
//      client = %this;
//   };

 
   // Create the player object
   %player = new RigidShape() 
   {
      dataBlock = BouncingBall;
      client = %this;
   }; 

   MissionCleanup.add(%player);

   // Player setup...
   %player.setTransform(%spawnPoint);
   %player.setShapeName(%this.name);
   
   // Update the camera to start with the player
   %this.camera.setTransform(%player.getEyeTransform());

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