float inputX = Input.GetAxis(“Horizontal”);
float inputY = Input.GetAxis(“Vertical”);
if(inputX > 0 && inputY < 0)//D and S
{
rotatationY += inputXturnSpeed;
rotatationY = Mathf.Clamp (rotatationY, 0, 135);
}
else if(inputX < 0 && inputY < 0)//A and S
{
rotatationY += inputXturnSpeed;
rotatationY = Mathf.Clamp (rotatationY, 225, 360);
}
else if(inputX > 0 && inputY > 0)//D and W
{
rotatationY += inputYturnSpeed;
rotatationY = Mathf.Clamp (rotatationY, 0, 45);
}
else if(inputX < 0 && inputY > 0)//A and W
{
rotatationY -= inputYturnSpeed;
rotatationY = Mathf.Clamp (rotatationY, -45, 0);
}
else if(inputX > 0 || inputX < 0)//A or D
{
rotatationY += inputXturnSpeed;
rotatationY = Mathf.Clamp (rotatationY, -90, 90);
}
else if(inputY > 0 || inputY < 0)//W or S
{
rotatationY -= inputYturnSpeed;
rotatationY = Mathf.Clamp (rotatationY, 0, 180);
}

			dir.y = rotatationY;
			transform.localRotation = Quaternion.Slerp(transform.localRotation, Quaternion.Euler(dir.x,dir.y,dir.z), Time.deltaTime * speed);

This code here makes the player rotate and face its direction.
Is there another way to make this code lesser and better? or is this fine which I highly doubt it.

I’m guessing a bit on your desired behavior. Here is a different way to do what I believe you are doing in this script. Note it depends on the object having a “normal” rotation where the front is facing positive ‘z’ and up is facing positive ‘y’.

using UnityEngine;
using System.Collections;

public class Facing : MonoBehaviour {

	public float speed = 2.0f;
	private Quaternion qTo;

	void Start() {
		qTo = transform.rotation;
	}
	
	void Update () {
		Vector3 direction = new Vector3(Input.GetAxis("Horizontal"), 0.0f, Input.GetAxis("Vertical"));

		if (direction != Vector3.zero)
			qTo = Quaternion.LookRotation (direction);

		transform.rotation = Quaternion.Slerp (transform.rotation, qTo, Time.deltaTime * speed);
	}
}
