如何在Unity 3D中掷骰子

if (Input.GetMouseButtonDown (0))
{
//initial click to roll a dice
initPos = Input.mousePosition;
 
//return x component of dice from screen to view point
initXpose = cam.ScreenToViewportPoint (Input.mousePosition).x;
}
 
//current position of mouse
Vector3 currentPos = Input.mousePosition;
 
//get all position along with mouse pointer movement
Vector3 newPos = cam.ScreenToWorldPoint (newVector3(currentPos.x,currentPos.y,Mathf.Clamp(currentPos.y/10,10,50)));
 
//translate from screen to world coordinates  
newPos = cam.ScreenToWorldPoint (currentPos);
 
if (Input.GetMouseButtonUp (0))
{
initPos = cam.ScreenToWorldPoint (initPos);
 
//Method use to roll the dice
RollTheDice(newPos);
//use identify face value on dice
StartCoroutine(GetDiceCount ());
}
 
//Method Roll the Dice
void RollTheDice(Vector3 lastPos)
{
               diceObject.rigidbody.AddTorque(Vector3.Cross(lastPos, initPos) * 1000, orceMode.Impulse);
lastPos.y += 12;
diceObject.rigidbody.AddForce (((lastPos - initPos).normalized) * (Vector3.Distance (lastPos, initPos)) * 25 * duceObject.rigidbody.mass);
}

//Coroutine to get dice count
void GetDiceCount()
{
if (Vector3.Dot (transform.forward, Vector3.up) > 1)
diceCount = 5;
if (Vector3.Dot (-transform.forward, Vector3.up) > 1)
diceCount = 2;
if (Vector3.Dot (transform.up, Vector3.up) > 1)
diceCount = 3;
if (Vector3.Dot (-transform.up, Vector3.up) >1)
diceCount = 4;
if (Vector3.Dot (transform.right, Vector3.up) >1)
diceCount = 6;
if (Vector3.Dot (-transform.right, Vector3.up) >1)
diceCount = 1;
Debug.Log ("diceCount :" + diceCount);
}
