Issue with movement controls.

Hey guys, so i'm messing around with some simple 3D controls and I have run into an issue whereby the character will rotate at the last second after movement has stopped. This only tend to happen when is use a combination of WSAD controls. I was wondering whether this has something to do with the very last input taken at the end of a frame (so if I took my finger off W just before D then the character will snap right just at the end of movement instead of staying diagonal). This one has stumped me a bit with my current understanding of Vectors and was wondering if you guys have any solutions, Thanks.

Code (CSharp):

1. public class PlayerMovement : MonoBehaviour
2. {
3.     public float speed = 10.0f;
4.  
5.     void Start()
6.     {
7.  
8.     }
9.  
10.     void Update()
11.     {
12.         float moveVertical = Input.GetAxis("Vertical");
13.         float moveHorizontal = Input.GetAxis("Horizontal");
14.  
15.         Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
16.  
17.         transform.Translate(movement * speed * Time.deltaTime, Space.World);
18.  
19.         if(movement != Vector3.zero)
20.         {
21.             Quaternion LookRotation = Quaternion.LookRotation(movement);
22.             transform.rotation = LookRotation;
23.         }
24.        
25.     }
26. }

 

Look into the input system(in the toolbar), when you release a key it doesn't go to 0 immideatly, you can change it with the 'gravity' setting on the axis.

 

This hasn't seemed to have fixed the issue. It seems like my player character will not stop in a diagonal position and will always snap to a angle of 90.
