Question RandomRange in void update

Hello, ist it possible to put randomrange in void update() im trying to obtain a new random value everytime an event happens,, but its only letting me put Random.Range in void (start) , thank you! Code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using System.Runtime.CompilerServices;
4. using Unity.VisualScripting;
5. using UnityEngine;
6.  
7. public class CharacterCtrl : MonoBehaviour
8. {
9.     public int Speed;
10.     public int JumpForce;
11.     public GameObject Character;
12.     public GameObject Coin;
13.     public Rigidbody2D rb2D;
14.     public float Countdown = 3f;
15.     public float Coinx = Random.Range(10f, 100f);
16.     public float Coiny = Random.Range(10f, 100f);
17.     // Start is called before the first frame update
18.     void Start()
19.     {
20.         rb2D.Sleep();
21.     }
22.  
23.     // Update is called once per frame
24.     void Update()
25.     {
26.        
27.         void Timer ()
28.         {
29.             Countdown = Countdown - Time.deltaTime;
30.         }
31.  
32.         Timer();
33.  
34.         if (Countdown <= 0)
35.         {
36.             rb2D.WakeUp();
37.         }
38.         if (Input.GetKeyDown(KeyCode.A) && Countdown <= 0 || Input.GetKeyDown(KeyCode.LeftArrow)&& Countdown <= 0)
39.         {
40.             rb2D.velocity = Vector2.left * Speed;
41.         }
42.  
43.         if (Input.GetKeyDown(KeyCode.D) && Countdown <= 0 || Input.GetKeyDown(KeyCode.RightArrow) && Countdown <= 0)
44.         {
45.             rb2D.velocity = Vector2.right * Speed;
46.         }
47.  
48.         if (Input.GetKeyDown(KeyCode.Space) && Countdown <= 0)
49.         {
50.             rb2D.velocity = Vector2.up * JumpForce;
51.         }
52.  
53.     }
54.  
55.     void OnTriggerEnter2D(Collider2D collider)
56.     {
57.         if (collider.gameObject == Coin)
58.         {
59.             Instantiate(Coin, new Vector2(Coinx,Coiny), transform.rotation);
60.         }
61.     }
62. }
63.  
64.  
65.  

Error message: UnityException: Range is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'CharacterCtrl'.

This has nothing to do with Update()
You can NOT call Random.Range when declaring a value. You need to declare it and then fill the value with Random.Range in Start((

 

Keep the declaration at the top, without setting a value.

Set a value, using Random.Range, in your ``` if (collider.gameObject == Coin)```
loop. I assume you want to initiate every coin at a random spot.

 

Worth noting that if you do actually need a random value when declaring the field, you can use `new System.Random()` instead.
