[FIXED] Lags on a camera movement (or a player movenent)

Hello All,

Unfortunately, I have faced an issue that looks quite tricky for a beginner.
When a player moves along the scene It seems a playground periodically lags.
I guess the root cause is related to a player movement approach or to a camera that follows the player.

The cinemachine is used as a camera.
Please, take a look below for the camera settings and the movement script:




Player's RigidBody2D:

Code (CSharp):

1. public class PlayerController : MonoBehaviour
2. {
3.     [SerializeField]
4.     private float speed = 1;
5.     [SerializeField]
6.     private Vector2 lookDirection = new Vector2(1, 0);
7.  
8.     private Rigidbody2D rigidbody2d;
9.     private Animator animator;
10.  
11.     // Start is called before the first frame update
12.     void Start()
13.     {
14.         rigidbody2d = GetComponent<Rigidbody2D>();
15.         animator = GetComponent<Animator>();
16.     }
17.  
18.     void FixedUpdate()
19.     {
20.         float horizontalMovement = Input.GetAxis("Horizontal");
21.         Vector2 movement = new Vector2(horizontalMovement, 0.0f);
22.         Vector2 position = rigidbody2d.position + movement * speed * Time.fixedDeltaTime;
23.  
24.         if (!Mathf.Approximately(horizontalMovement, 0.0f))
25.         {
26.             lookDirection.x = horizontalMovement;
27.             lookDirection.Normalize();
28.         }
29.  
30.         animator.SetFloat("Speed", movement.magnitude);
31.         animator.SetFloat("Direction", lookDirection.x);
32.  
33.         rigidbody2d.MovePosition(position);
34.     }
35. }
36.  

PS: I have tried to google the issue and saw a lot of topics but neither of them has helped.

Thanks All in advance.

SOLUTION:
The root cause was that I have not tried to build and run with enabled Interpolation.
Due to I have enabled Interpolation and tried it only with Unity emulator It produced jerking and I have thought Interpolation has not fixed the issue.

So that, Guys, I would recommend trying to build with enabled Interpolation and run your game.

 

Is your camera movement in LateUpdate rather than Update?

 

Hi orchard800,

There is a screenshot with the camera settings above.
The camera update is set to Smart Update.
I have tried to change it to Late Update and Fixed Update but it produces more stutters.

 

Hopefully fixed the issue!
