How to spawn building for 5 second after user click button?

Unity Engine
1

Whenever I coded for spawning building when the use click a button, instead of waiting 5 seconds before the buildings, my coding become such that whenever the timing is less than 5 seconds, the buildings would not spawn and it would only create when the timing is more than 5 seconds.

My idea is that when instead of waiting 5 seconds before the building is created instantly when user create button, my idea is to when the user create the building, it would wait 5 seconds before the building automatuically spawn when the user create the button.I dun have the code right now since i left it in school, but I would post it tomorrow morning but if got any idea, do give me advice.

Ok lets clear things up.
What exactly do you need?

  1. Click - Wait 5 sec - Spawn
  2. click - Spawn - Wait 5 sec - Do something else

However things you should look up are Coroutines and Invoke.

E.g. for case 1):

if(Input.GetMouseButtonDown(0)){
Invoke("SpawnBuilding", 5);
}
3
  1. Click building icon, wait 5 sec then the building would spawn.

Ok look at the example i gave above…that does exactly that, or tell if you need further explanation.

My code is like that.

GameObject SchoolTiming = GameObject.Find ("CurrentTime");
SchoolScript s1 = GetComponent<SchoolScript>();
					
GameObject SchoolStartTiming = GameObject.Find ("StartTime");
SchoolScript s1a = GetComponent<SchoolScript>();

GenerateTiles script = GetComponent<GenerateTiles>();
					
					
if(!script.CheckOccupied(hit.collider.gameObject, 2, 2))
{
						
							
						
	script.SetOccupied(hit.collider.gameObject ,2, 2);
	
	if(s1.CurrentTime  >= 5) 
	{
		
								
			Instantiate (school, hit.collider.gameObject.transform.position, Quaternion.identity);
								
	}
						
}

InputScript file

// Update is called once per frame
void Update () {
		StartTime = Time.time;
		//SchoolSeconds += Time.deltaTime;
		CurrentTime = StartTime - 0 ;
	
}

SchoolScript file

So, in the end, what is wrong with my code. How to make it such that when the user institatite and click the button, the program would wait 5 seconds before spawning the buildings.

I believe Arterie has answered your question. Invoke will call the function after a certain amount of delay. So all you have to do is to define the function SpawnBuilding as shown in Arterie’s example. Then call Invoke when your button has been clicked.

8 
    if(s1.CurrentTime  >= 5) 
    {
            Instantiate (school, hit.collider.gameObject.transform.position, Quaternion.identity); 
    }

Using invoke here instead of the if-clause should work just fine.
Though as wolfhunter said you need to define a SpawnBuilding function where you enclose the Instantiate call.

9 
public GameObject house;
public float SpawnDelay;

void Update() {
	if (Input.GetMouseButtonDown(0)) {
		StartCoroutine(SpawnBuilding(SpawnDelay));
	}
}

public IEnumerator SpawnBuilding(float waitTime) {
	yield return new WaitForSeconds(waitTime);
	GameObject.Instantiate(house, Vector3.zero, Quaternion.identity);
}

just do

function Update () {

    if(Input.GetMouseButtonDown(0)){

       yield WaitforSeconds (5);
       //spawn building

      }
}
