I’ve tried using other peoples solutions, but they’re either outdated and not formatted right for my version of unity or they just dont work for me.
#pragma strict
var rotationSpeed = 100;
var jumpHeight = 8;

private var isFalling = false;

function Update () 
{
	//Ball Rotation 
	var rotation : float = Input.GetAxis ("Horizontal") * rotationSpeed;
	rotation *= Time.deltaTime;
	GetComponent.<Rigidbody>().AddRelativeTorque (Vector3.back * rotation);
	if (Input.GetKeyDown(KeyCode.W) && isFalling == false) {
		Rigidbody.velocity.y = jumpHeight;
		isFalling = true;
	}
}

function onCollisionStay ()
{
	isFalling = false;
}

The solutions you found are not outdated or formatted incorrectly. It’s just that they’ve declared OnCollisionStay(col : Collision ) correctly, with a capital “O” and the correct parameter signature.

It’s all in the manual…
