So .. I have that code , and I want to Spawn something like a coin

I have that code

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class SpawnHazards : MonoBehaviour {
7.     #region Variables
8.     //Public
9.  
10.  
11.     //Private
12.     [SerializeField]
13.     public float minX = 0.0f;
14.     [SerializeField]
15.     public float maxX = 0.0f;
16.     [SerializeField]
17.     private int minHazardToSpawn = 1;
18.     [SerializeField]
19.     private int maxHazardToSpawn = 6;
20.     [SerializeField]
21.     private GameObject[] hazards;    //Potential array of hazards
22.     [SerializeField]
23.     private float timeBetweenSpawns = 0.0f;
24.     public bool canSpawn = false;
25.     private int amountOfHazardToSpawn = 0;
26.     private int hazardToSpawn = 0;
27.  
28.     private UIFunctions uiFunctions;
29.     #endregion
30.  
31.     #region UnityFunctions
32.     void Start()
33.     {
34.         uiFunctions = GameObject.FindGameObjectWithTag("GameManager").GetComponent<UIFunctions>();
35.         canSpawn = true;
36.     }
37.  
38.  
39.     void Update () {
40.         if(canSpawn == true && uiFunctions.gameStarted == true)
41.         {
42.             StartCoroutine("GenerateHazard");
43.            
44.         }
45.  
46.     }
47.     #endregion
48.  
49.     private IEnumerator GenerateHazard()
50.     {
51.        
52.         canSpawn = false;
53.         timeBetweenSpawns = Random.Range(0.5f, 2.0f);
54.         amountOfHazardToSpawn = Random.Range(minHazardToSpawn, maxHazardToSpawn);
55.         for(int i = 0; i < amountOfHazardToSpawn; i++)
56.         {
57.             Vector3 spawnPos = new Vector3(Random.Range(minX, maxX), Random.Range(8.5f, 16f), -4.079776f);   //Generate s spawnPosition
58.             Instantiate(hazards[hazardToSpawn], spawnPos, Quaternion.identity);
59.         }
60.         yield return new WaitForSeconds(timeBetweenSpawns);
61.         canSpawn = true;
62.     }
63. }
64.  
65.  

I actually want to add a new spawn object and when that object hit my player , i want to add a coin )
I tried different method but don't work ..
That's my collision script :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5. using UnityEngine.UI;
6. using UnityEngine.Audio;
7.  
8. public class HazardCollisionFunction : MonoBehaviour {
9.  
10.     #region Variables
11.  
12.     //Public
13.  
14.  
15.     //Private
16.     private UIFunctions uiFunctions;
17.     public ParticleSystem hazardDustParticles;
18.  
19.  
20.  
21.     #endregion
22.  
23.     #region UnityFunctions
24.     void Start()
25.     {
26.         uiFunctions = GameObject.FindGameObjectWithTag("GameManager").GetComponent<UIFunctions>();
27.  
28.     }
29.  
30.     void Update()
31.     {
32.  
33.  
34.     }
35.     #endregion
36.  
37.     private void OnCollisionEnter(Collision collision)
38.     {
39.         if(collision.gameObject.tag == "Platform")
40.         {
41.             Destroy(Instantiate(hazardDustParticles.gameObject, transform.position, Quaternion.identity), hazardDustParticles.startLifetime);
42.  
43.             Die();
44.            
45.  
46.         }
47.         if (collision.gameObject.tag == "Player")
48.         {
49.             Die();
50.             uiFunctions.GameEnded();
51.            
52.         }
53.  
54.     }
55.  
56.     public void Die()
57.     {
58.         Destroy(gameObject);
59.     }
60. }
61.  

 

"dont work" how?

 

I create that:

Code (CSharp):

1.    private IEnumerator GenerateSphereHazard()
2.     {
3.  
4.         canSpawn = false;
5.         timeBetweenSpawns = Random.Range(0.5f, 2.0f);
6.         amountOfHazardToSpawn = Random.Range(minHazardToSpawn, maxHazardToSpawn);
7.         for (int i = 0; i < amountOfHazardToSpawn; i++)
8.         {
9.             Vector3 spawnPos = new Vector3(Random.Range(minX, maxX), Random.Range(8.5f, 16f), -4.079776f);   //Generate s spawnPosition
10.             Instantiate(sphereHazard, spawnPos, Quaternion.identity);
11.         }
12.         yield return new WaitForSeconds(timeBetweenSpawns);
13.         canSpawn = true;
14.     }

and that

Code (CSharp):

1.     void Update () {
2.         if(canSpawn == true && uiFunctions.gameStarted == true)
3.         {
4.             StartCoroutine("GenerateHazard");
5.             StartCoroutine("GenerateSphereHazard");
6.            
7.         }
8.  
9.     }
