Ball Jittering Problem !!

Hello, I am a newbee in Unity world, I am building a simple pong game where user serves the ball and scores a point if the ball reaches the opponent’s goal post. However I have a problem in the ball movement. The ball movement is not smooth, it is jittering dinn know why. Here are the methods I used.

  1. Used Interpolate.
  2. Used fixed frame rate in the code.
  3. Used the code in fixed update.

Attributes attached to the ball are -

  1. bounciness Material.
  2. ball gets a velocity when collides with the paddles
  3. Velocity is normalised.
  4. Sphere collider.

Any help is highly appreciated.

Don’t set the velocity every frame, just addforce or set the velocity ONCE and not every frame that it’s moving
