How to make a delay with C# in Unity3D?

Question

I just started to learn c# in unity. I followed a tutorial, but i wanna add some things.

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

pub         


        

Answer 1

I can assume that it's a windows-forms application so that you're better not to use Thread.Sleep as it will block the UI thread.

Instead, use: System.Windows.Forms.Timer

Answer 2

Use Coroutine (as I see this is Unity3D code):

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

    IEnumerator SetCountText ()
    {
        countText.text = "Count: " + count.ToString ();
        if (count >= 1)
        {
            winText.text = "You Win!";
            yield return new WaitForSeconds(1f);
            Application.LoadLevel(1);
        }
    }

Answer 3

In Unity waits are usually done with help of a WaitForSeconds class.

In your case you will have to change OnTriggerEnter and SetCountText a bit so that they return IEnumerable type:

IEnumerable OnTriggerEnter(Collider other) 
{
    if (other.gameObject.CompareTag ( "Pick Up"))
    {
        other.gameObject.SetActive (false);
        count = count + 1;
        yield return SetCountText ();
    }
}

IEnumerable SetCountText ()
{
    countText.text = "Count: " + count.ToString ();
    if (count >= 1)
    {
        winText.text = "You Win!";
        yield return new WaitForSeconds(5); // Wait for seconds before changing level
        Application.LoadLevel(1);
    }
}
