How do i wait for seconds

Questions & Answers
1

This is my script. I want to wait a few seconds before loading the level but still display the message while waiting (down in the bottom)

public class PlayerController : MonoBehaviour {

public float speed;
public Text countText;
public Text winText;

private Rigidbody rb;
private int count;

void Start ()
{
	rb = GetComponent<Rigidbody>();
	count = 0;
	SetCountText ();
	winText.text = "";
}

void FixedUpdate ()
{
	float moveHorizontal = Input.GetAxis ("Horizontal");
	float moveVertical = Input.GetAxis ("Vertical");

	Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

	rb.AddForce (movement * speed);
}

void Update ()
{
	if (Input.GetKey ("escape")) {
		Application.LoadLevel (0);
	}
}
void OnTriggerEnter(Collider other)
{
	if (other.gameObject.CompareTag ("Pick Up")) {
		other.gameObject.SetActive (false);
		count = count + 1;
		SetCountText();	
	}
	}

void SetCountText ()
{
	countText.text = "Coins: " + count.ToString ();
	if (count >= 12) 
		{
		winText.text = "Nice!";
		Application.LoadLevel(0);
		}
}

}

void OnTriggerEnter(Collider other)
{
if (other.gameObject.CompareTag (“Pick Up”)) {
other.gameObject.SetActive (false);
count = count + 1;
SetCountText();
StartCoroutine ( WaiTtoload());
}

IEnumerator WaiTtoload()
{
yield return new WaitForSeconds (3f);
Application.LoadLevel(0); //delete this line frome SetCountText() function.
}
