Adding a curvature to the Movement of A Player when moving horizontally

Hey. I'm a pretty big noob when it comes to unity.
I'm self taught when it comes to programming, I finally got myself to work on a game, or better said a character controller.

I wanted to mimic the controlls of a game called Nier:Automata, atleast the basic feel of moving around and how the camera behaves. So far I've been able to move the character in relation to the camera.

I calculate the angle this way:

Code (CSharp):

1. void Update () {
2.  
3.         Vector2 input = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
4.         input.Normalize();
5.  
6.         if (input != Vector2.zero)
7.         {
8.             float targetRotation = Mathf.Atan2(input.x, input.y) * Mathf.Rad2Deg + cameraBase.transform.eulerAngles.y;
9.             targetRotation = Mathf.SmoothDampAngle(transform.rotation.eulerAngles.y, targetRotation, ref turnSmoothVelocity, turnSmoothTime);
10.  
11.             transform.rotation = Quaternion.Euler(0f, targetRotation, 0f);
12.         }
13.      
14.         bool running = Input.GetKey(KeyCode.LeftShift);
15.         float speed = ((running) ? runSpeed : walkSpeed) * input.magnitude;
16.         rigidbody.MovePosition(transform.position + transform.forward * speed * Time.deltaTime);
17.      
18.     }

As you can see I just move the character by turning him in the apropriate direction and then adding a forward force.

This however has one major difference looking at my inspiration Nier:Automata - When you move horizontally in my "game" the character just moves on the horizontal axis. However in Nier:Automata, the Character runs in a big circle.

My camera is focused on the character by just this code

transform.position = target.position - offset * currentZoom;

I can rotate the camera around the character with this code

Code (CSharp):

1.  
2.         mouseX = Input.GetAxis("Mouse X");
3.         mouseY = Input.GetAxis("Mouse Y");
4.  
5.         inputX = Input.GetAxis("Joystick Horizontal");
6.         inputY = Input.GetAxis("Joystick Vertical");
7.  
8.         rotationY += (mouseX + inputX) * inputSensitivity * Time.deltaTime;
9.         rotationX += (mouseY + inputY) * inputSensitivity * Time.deltaTime;
10.  
11.         rotationX = Mathf.Clamp(rotationX, -clampAngle, clampAngle);
12.  
13.         Quaternion localRotation = Quaternion.Euler(rotationX, rotationY, 0.0f);
14.         transform.rotation = Quaternion.Lerp(transform.rotation, localRotation, smoothRotation);

So do you have any idea on how I can rotate the character like in nier:automata in my script?

 

Took a glimpse, you need to gradually change your rotation I think.

Code (CSharp):

1. //new variable
2. public float rotaPerSec;//in degrees
3.  
4. //within your rotation "if" statement
5. //transform.rotation = Quaternion.Quler(...)//replaced with:
6. transform.rotation = Quaternion.RotateTowards(transform.rotation, targetRotation, rotaPerSec * Time.deltaTime);
