not work Coroutine

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class game : MonoBehaviour
7. {
8.     public GameObject[] balls;
9.     public int random;
10.     public void Ran()
11.     {
12.         random = Random.Range(0, max: 2);
13.     }
14.     // Use this for initialization
15.     void Start()
16.     {
17.     }
18.  
19.     // Update is called once per frame
20.     void Update()
21.     {
22.         if (Input.GetKeyDown("f"))
23.         {
24.             StartCoroutine("Fade");
25.         }
26.  
27.         IEnumerator Fade()
28.         {
29.             Instantiate(balls[random], balls[random].transform.position, Quaternion.identity);
30.         }
31.     }
32. }
33.  
34.  
35.  

 

Take your IEnumerator our of the Update function.

 

You declared corutine at method level, but calling it at class level. Do what chubbspet said or change how do you start coroutine to this

Code (CSharp):

1. StartCoroutine(Fade());
