Unity 3D - Rotate (smoothly) towards a target

Question

I wanted to know if there is a method on which I can rotate an object with an angle given (a float to be precise), I use trigonometry to calculate the angle between the two objects in a (x, z) plane perspective (using y as the height coordinates).

This is the code I use to calculate the angle, but I want to know if a float would be anough data (then pass a Vector3 with that angle calculation as the Y parameter, since I want to rotate the Y axis).

//Makes the player heads to the direction the ball is...
public float headOnBall()
{
    Vector3 playerPos = this.transform.position;
    Vector3 ballPos = ball.transform.position;

    float angle;
    float x = (playerPos.x - ballPos.x);
    float z = (playerPos.z - ballPos.z);

    if(playerPos.z < ballPos.z || playerPos.x < ballPos.x && playerPos.z < ballPos.z)
    {
        angle = (Mathf.Atan2(z, x) + (Mathf.PI * 2)) * Mathf.Rad2Deg;
    }
    else
    {
        angle = Mathf.Atan2(z, x) * Mathf.Rad2Deg;
    }

    return angle;
}

Thanks in advance.

There's a few functions for this already in Unity 3D:

• Vector3.RotateTowards https://docs.unity3d.com/ScriptReference/Vector3.RotateTowards.html
• Quaternion.RotateTowards https://docs.unity3d.com/ScriptReference/Quaternion.RotateTowards.html
