Drop Proyectile Physics Effect

Hi! I am trying to shoot a shell from a cannon and play with the drop, but I dont know how to make the Xample2 image efect, becase I cant modify the center of mass.

Xample1 is the efect that I have now in Unity.

I was trying to use this code but doesnt works.

public class Center_Of_Mass : MonoBehaviour
{

public Vector2 CenterOfMass2;
public bool Awake;
public float AngularSpeed;

protected Rigidbody2D r;

// Start is called before the first frame update
void Start()
{
r = GetComponent();
}

// Update is called once per frame
void Update()
{
r.centerOfMass = CenterOfMass2;
r.WakeUp();
Awake = !r.IsSleeping();
}

private void OnDrawGizmos()
{
Gizmos.color = Color.red;
Gizmos.DrawSphere(transform.position + transform.rotation * CenterOfMass2, 0.1f);
}
}

I tried to use another code, but I do not reach my objetive.

The new code rotate de Shell / time, but it doesnt work with the distance or angle of the shoot. The shell rotate at the same speed, doesnt matter the other features.

I have reached a similar effect, but it is far to be perfect:


public class P1_Mover : MonoBehaviour
{

public float speed;
public Rigidbody2D rb;
public float turnSpeed;

// Start is called before the first frame update
void Start()
{
rb = GetComponent();
rb.velocity = transform.right * speed;

//Vector2 force = new Vector2(speed, 0);
//rb.AddForce(force);
}

private void Update()
{
transform.rotation = Quaternion.Euler(Vector3.forward * rb.velocity.y * turnSpeed);
}

}


The problem:


This is the effect I want to reach

Why are you multiplying by velocity.y?
Just set ‘transform.forward’ to ‘velocity.normalized’.

I want to reach the curve drop efect. [Example2]

In the video I am showing that I have reached a similar effect, but it is far to be perfect.

Still no have solution
