ball the roll

please help me with it script

var Fspeed = 250.0;
var Tspeed = 250.0;
var jump = 250;
var gravitypull = 0;


function Start(){
	Screen.lockCursor = true;
}

function FixedUpdate() {
	rigidbody.AddForce (Vector3(0, gravitypull, 0));
	
	var cameraTransform = Camera.main.transform;
	
	// Forward vector relative to the camera along the x-z plane
	var forward = cameraTransform.TransformDirection(Vector3.forward);
	forward.y = 0;
	forward = forward.normalized;
	
	// Right vector relative to the camera
	// Always orthogonal to the forward vector
	var right = Vector3(forward.z, 0, -forward.x);
	
	
	if (Input.GetKey ("r")) {
		Application.LoadLevel(0);
	}
	
	if (Input.GetKey ("a")) {
		
		rigidbody.AddTorque(forward * Tspeed * Time.deltaTime);
		rigidbody.AddForce(right * -Fspeed * Time.deltaTime);
		
	}
	
	
	if (Input.GetKey("d")) {
		rigidbody.AddTorque(forward * -Tspeed * Time.deltaTime);
		rigidbody.AddForce(right * Fspeed * Time.deltaTime);
		
	}
	if (Input.GetKey("w")) {
	
		rigidbody.AddTorque(right * Tspeed * Time.deltaTime);
		rigidbody.AddForce(forward * Fspeed * Time.deltaTime);
		
	}
	
	if (Input.GetKey ("s")) {
		rigidbody.AddTorque(right * -Tspeed * Time.deltaTime);
		rigidbody.AddForce(forward * -Fspeed * Time.deltaTime);
		
	}
	if (Input.GetKeyDown ("space")) {
		rigidbody.AddForce(0,jump,0);
		
	}
	
}

but it is no realistik
it is sample http://www.wooglie.com/playgame.php?gameID=292
sorry for my english

anyone help me create roll the ball similar this http://www.wooglie.com/playgame.php?gameID=292 ?
sorry for my english

I am about to go into a meeting. I wrote something similar but without the force added. That may help you in teh long run.

I believe my script had camera problems. They could be overcome but I did not have the time to complete it.

Thanks,I look it now!

thanks, but your script have similar problem with my script, is slow rotation of the ball when I press “w” or “up” and rotatate camera
it is my script:

var force=10;

var torque = 10;

var _IsJumping = false;

var jump = 300;



function Start(){

	Screen.lockCursor = true;

}



function OnCollisionEnter(collision : Collision) {

for (var contact : ContactPoint in collision.contacts) {

_IsJumping = false;

}

}



function FixedUpdate() {

	

	var cameraTransform = Camera.main.transform;

	

	// Forward vector relative to the camera along the x-z plane

	var forward = cameraTransform.TransformDirection(Vector3.forward);

	forward = forward.normalized;

	

	// Right vector relative to the camera

	// Always orthogonal to the forward vector

	

	var right = Vector3(forward.z, 0, -forward.x);

	var TorqueRight = Vector3(forward.x, 0, forward.z);

	

	

	if (Input.GetKeyDown ("r")) {

		Application.LoadLevel(0);

	}

	

	if (Input.GetKey ("a") !_IsJumping || Input.GetKey ("left") !_IsJumping) {

		

		rigidbody.AddForce(right * -force, ForceMode.Acceleration);

		

	}

	if (Input.GetKey ("a") || Input.GetKey ("left")) {

		

		rigidbody.AddTorque(TorqueRight * torque);

		

	}

	

	if (Input.GetKey("d") !_IsJumping || Input.GetKey("right") !_IsJumping) {

		rigidbody.AddForce(right * force, ForceMode.Acceleration);

		

	}

	if (Input.GetKey("d") || Input.GetKey("right")) {

		rigidbody.AddTorque(TorqueRight * -torque);

		

	}

	if (Input.GetKey("w") !_IsJumping || Input.GetKey("up") !_IsJumping) {

		rigidbody.AddForce(forward * force, ForceMode.Acceleration);

		

	}

	if (Input.GetKey("w") || Input.GetKey("up")) {

		rigidbody.AddTorque(right * torque);

		

	}

	

	if (Input.GetKey ("s") !_IsJumping || Input.GetKey ("down") !_IsJumping) {

		rigidbody.AddForce(forward * -force, ForceMode.Acceleration);

		

	}

	

	if (Input.GetKey ("s") || Input.GetKey ("down")) {

		rigidbody.AddTorque(right * -torque);

		

	}

	if (Input.GetKey ("space") !_IsJumping) {

		_IsJumping = true;

		rigidbody.AddForce(0,jump,0);

		

	}

	

}

Ramp up the torque. If you specifically want forward faster, multiply it.

rigidbody.AddForce(forward * force * 10.0, ForceMode.Acceleration);

Other than that just change your torque or force to something bigger.

It doesn’t help.
I mean - if you do not use “a” and “d” and manage interpretation “w” and “s” and turn the camera - the ball does not have time to change direction.

The fact that I use a low rate of acceleration and rotation.
I reconfigured physics.

I have Max Angular Velocity = 100;

But I have slow rotates when use w or up and camera and don’t use a,d or left,right

If i use high addforce and addtorque a ball no roll it slides and it’s drags on the surface

sorry for my poor english
