Help with a simple spawner

Scripting
1

I’m new to unity, and my C# skills are a little rusty. I’m trying to make a spawner to spit out a random prefab from a list of preabs every 2.5 seconds. I made my empty spawner object but i seem to be stuck on the list part of it. Most of the posts i have found are in java and i’m not 100% sure how to set this up in C#. Any help would be great.

	float SpawnTime = 2.5;
    List<GameObject> prefabList = new List<GameObject>();
    public GameObject Prefab1;
    public GameObject Prefab2;
    public GameObject Prefab3;

 
    void Start()
    {
        prefabList.Add(Prefab1);
        prefabList.Add(Prefab2);
        prefabList.Add(Prefab3);
        
		
        int prefabIndex = UnityEngine.Random.Range(0,3);
        Instantiate(prefabList[prefabIndex]);
 
    }
	void Update()
	{
			
	}
}

Well, you look like you’re on the right track with your instantiation code, but you missed a couple of spots here and there:

    // C# floats have a trailing 'f', or else it's a double
    float SpawnTime = 2.5f; 

    public List<GameObject> prefabList;

    // you don't need a GameObject reference for each item.
    // Make that list public, and unity will serialize it, so you can fill 
    // it up in the inspector panel (arrays also work).
 

    // at start, just call a coroutine that will run an endless loop,
    // spawning a randomly chosen item every so many seconds.
    void Start()
    {
           StartCoroutine(SpawnRandom());        
    }

    IEnumerator SpawnRandom()
    {
            // this loop will run infinitely while the game object or component
            // is enabled in the scene, yielding for the given amount of time between each iteration
            
            while(this.enabled)
            {
                  yield return new WaitForSeconds(SpawnTime);                  

                  Instantiate(prefabList[Random.Range(0,prefabList.Count)]);
            }
    }

}

Hope this helps.

Cheers
