[CLOSED] My rigidbody jitter

I have a rigidbody with WASD movements, which rotates according to the point where it looks at the camera. When I start the scene, however, the rigidbody trembles. I tried to mark it "interpolate" and put the movements in FixUpdate (), but the result does not change.
Can someone help me?
This is the code of my rigidbody:

Code (CSharp):

1. public class movimento : MonoBehaviour
2. {
3.  
4.    [SerializeField] float walk = 1;
5.    [SerializeField] float run = 2;
6.     private Rigidbody rig;
7.  
8.     // Start is called before the first frame update
9.     void Start()
10.     {
11.       rig = GetComponent<Rigidbody>();
12.     }
13.  
14.     // Update is called once per frame
15.     void Update()
16.     {
17.         if (Input.GetKeyDown(KeyCode.LeftShift)) walk = (walk + run);
18.         if (Input.GetKeyUp(KeyCode.LeftShift)) walk = (walk - run);
19.      }
20.  
21.      void FixedUpdate ()
22.     {
23.         float Horizontal = Input.GetAxis("Horizontal");
24.         float Vertical = Input.GetAxis("Vertical");
25.         Vector3 movement = new Vector3(Horizontal, 0f, Vertical);
26.          rig.rotation = Quaternion.Euler(0f, Camera.main.transform.eulerAngles.y, 0f);
27.          rig.position += rig.rotation * movement * walk * Time.deltaTime;
28.     }
29.   }
30.  

 

Hi, very thanks for the reply. Unfortunately I am studying C# but not I still know the terms of unity well.
However using MovePosition or MoveRotation, I get these error message :

error CS1656: Cannot assign to 'MovePosition' because it is a 'method group'
error CS0019: Operator '*' cannot be applied to operands of type 'method group' and 'Vector3'


So I can't just replace them, but should I use these by changing my script?

 

Thanks for the info. I understood the mistake, but despite this once inserted, the object shakes the same.
Please, could you show me how you would use them on my script? ... I would like to understand if I am wrong or if this is not the problem.

 

With your advice, I tried to create an object with MovePosition but I can't make it move in the direction it is rotated. What should I add to implement axes on WASD based on rotation?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. public class movimento : MonoBehaviour
5. {
6.    [SerializeField] float walk = 1;
7.    [SerializeField] float run = 2;
8.     Vector3 movement = Vector3.zero;
9.     private Rigidbody rig;
10.     // Start is called before the first frame update
11.     void Start()
12.     {
13.       rig = GetComponent<Rigidbody>();
14.     }
15.     // Update is called once per frame
16.     void Update()
17.     {
18.         if (Input.GetKeyDown(KeyCode.LeftShift)) walk = (walk + run);
19.         if (Input.GetKeyUp(KeyCode.LeftShift)) walk = (walk - run);
20.         float Horizontal = Input.GetAxis("Horizontal");
21.         float Vertical = Input.GetAxis("Vertical");
22.         movement = new Vector3(Horizontal, 0f, Vertical);
23.     }
24.      private void FixedUpdate ()
25.     {
26.    
27.         rig.MovePosition(rig.position + movement * walk * Time.fixedDeltaTime);
28.      
29.     }
30.   }

 

Based on what I see,

And based on melvmays suggestion

Have your tried adding in

"transform.forward" instead of "transform.right"
?

This is just my take on implementing his suggestion, I'm not sure if it works

 

hello, thanks for the reply. You could tell me, how to use MoveRotation to make the object turn in the direction it walks with WASD (I tried a lot but the rigidbody walks but it doesn't rotate in the direction it moves). I think if in addition to moveposition I apply moverotetion the situation can improve (to rotate it I used a script without quaternions at this moment).
