Manual physics update Not Applying

hello,

i am having an issue with my applying manual physics update..

in my script i have a ball and when i choose to shoot the ball a function StrikeBall() is called..

this adds a velocity to the ball.. i do not want to add a force. i want to directly decide the velocities..

in my update function i have a something which decreases the velocity of the ball a certain amount every FixedDeltaTime..

and then i call Physics.simulate(time.FixeddeltaTime);

but the ball is not moving..

the in the debug the ball velocities are correct.. (it gives the velocity and decreases as expected)

but the ball is not moving..

here is my code:

Code (CSharp):

1. void Update()
2.     {
3.         if (!gotCueRotationManager)
4.         {
5.             GetCueRotationManager();
6.         }
7.  
8.         DecreaseVelocities();
9.         print(ballRB[0].velocity);
10.        
11.        
12.         Physics.Simulate(Time.fixedDeltaTime);
13.     }
14.  
15.  
16.  
17.  
18.     public void StrikeBall()
19.     {
20.         print("striking Ball - Gamephysics");
21.         ballRB[0].velocity = cueRotationManager.getForce();
22.         BallDirections(cueRotationManager.getForce());
23.     }
24.  
25.     public void DecreaseVelocities()
26.     {
27.         if(ballRB[0].velocity.magnitude >= 0.5f)
28.         {
29.             ballRB[0].velocity = new Vector3(ballRB[0].velocity.x - (ballDirections[0].x*Time.fixedDeltaTime), ballRB[0].velocity.y - ballDirections[0].y * Time.fixedDeltaTime, ballRB[0].velocity.z - ballDirections[0].z * Time.fixedDeltaTime);
30.         }
31.     }

 

Found the Solution i was linking the RB Prefab not the Instantiated Version..
