Gravity.FixedUpdate C# (CSharp) Méthode

    void FixedUpdate()
    {
        Vector3 r = transform.parent.position-transform.position;

        acceleration = r.normalized * (G * p_Rigidbody.mass / r.sqrMagnitude);

        velocity += acceleration * Time.deltaTime;
        transform.position = transform.position+velocity*Time.deltaTime;
    }
