Instantiate a certain amount of prefabs, unity c#

Question

I wondered how i can instantiate a certain amount of prefabs c#.

ex:

if(Input.GetKeyDown(KeyCode.K))
{
//Instantiate 20 prefabs
}

Answer 1

When the button is pressed, run a loop that loops until the Space value -1 is reached then instantiate a prefab each time in the loop. This should be done in the Update function. It shouldn't keep instantiating if you do this correctly.

int Space = 20;
public GameObject prefab;

void Update()
{
    if (Input.GetKeyDown(KeyCode.K))
    {
        //Instantiate 20 prefabs
        for (int i = 0; i < Space; i++)
        {
            GameObject obj = Instantiate(prefab);
            obj.transform.position = new Vector3(0, 0, 0);
        }
    }
}
