Problem with basketball game

Questions & Answers
1

I’m creating a basketball game. I have a problem where if the user presses r, it returns the ball back to the user. The problem is after multiple tries, the ball has a physic problem and I’ve noticed the thrust increases more and more after I press r. Can someone help me?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour
{

    public GameObject basketball;
    Rigidbody basketballRB;

    Camera FPSCam;

    private bool holdingBall;
    public float thrust;

    void Start()
    {
        basketballRB = basketball.GetComponent<Rigidbody>();
        FPSCam = GetComponentInChildren<Camera>();

        holdingBall = true;
    }

    void FixedUpdate()
    {

        if (holdingBall)
        {
            basketballRB.useGravity = false;
            basketball.transform.position = FPSCam.transform.position;
        }

        if (Input.GetKeyDown("mouse 0") && holdingBall)
        {
            Shoot(thrust);

            holdingBall = false;
            basketballRB.useGravity = true;
        }

        if (Input.GetKey("r"))
        {
            holdingBall = true;
        }
    }

    public void Shoot(float thrust)
    {
        basketballRB.AddForce(FPSCam.transform.forward * thrust);
    }

}

If you don’t need the basketball to collide with the player, you can set a different layer to them and go to “Edit - Project Setting - Physics” to make sure basketball layer will not collide with the player layer at “Layer Collsion Matrix”.
