Jump Script (Always Up)

Question

I am using a sphere in a 3D Side-Scroller (no forward or backward) and therefore using my own controls, when I jump I can just hold it and keep going up. I need it to be like you cant jump unless on the floor. Here is my script:

 var JumpSpeed = 100.0f;
 
 function FixedUpdate() 
 {
     //Left
     if(Input.GetKey(KeyCode.LeftArrow) )
     {
         rigidbody.AddForce(Vector3.left*5);
     }
     if(Input.GetKey(KeyCode.A) )
     {
         rigidbody.AddForce(Vector3.left*5);
     }
     //Right
     if(Input.GetKey(KeyCode.RightArrow))
     {
         rigidbody.AddForce(Vector3.right*5);
     }
     if(Input.GetKey(KeyCode.D))
     {
         rigidbody.AddForce(Vector3.right*5);
     }
     //Jump
     
     if(Input.GetKey(KeyCode.W))
     {
         Jump();
     }
 }
 function Jump()
 {
         animation.Play("jump_pose");
         rigidbody.velocity += Vector3.up * JumpSpeed;
 }

For an object with rigidbody

     if(Input.GetKeyDown(KeyCode.W))
     {
         Jump();
     }
  }
         
  function Jump()
  {
     animation.Play("jump_pose");
     rigidbody.AddForce(Vector3.up * JumpSpeed, ForceMode.Impulse);
  }

Won't this just make the ball keep moving upwards if the player keeps tapping W?

Yup. Its a nudge in the right direction :)

If people want to make games they need to work things out. If we spell it out, people won't learn anything!

Yes but that is the problem, I can't use a character controller because im using a sphere. That means no isGrounded.

 if ( rigidbody.velocity.y == 0 )
 
 if ( rigidbody.velocity.y != 0 )
