How to integrate timer into my C# script?

Questions & Answers

Hello Unity Answers,

I’m looking for some help on how to create a timer within my script which appears on screen when the player collides into a cube.

At the moment when the player collides into the cube a question appears on screen. I would like to display a timer counting down from 10 to 0, with 0 destroying the pop up box and the player going back to the start.

Any ideas/help/suggestions would be much appreciated.

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

public class Question1 : MonoBehaviour {
	
	private Rect windowRect = new Rect (500, 100, 400, 200); //Window size
	public bool question1;
	private int count;
	public Text countText;


	void start()
	{
		count = 0;
		SetCountText ();
	}

	
	void OnGUI()
	{
		windowRect = GUI.Window (0, windowRect, WindowFunction, "Ebola Quiz Island"); //window on screen
	}
	

	void WindowFunction (int windowID) 
	{
		// Draw any Controls inside the window here

		GUI.Label (new Rect (30, 25, 200, 50), " What year did Ebola begin?"); // Question
		
		if (GUI.Button (new Rect (20, 100, 100, 30), "1976")) // Correct Answer
		{
			Destroy (this.gameObject);
			count = count + 1;
			SetCountText ();
		} 

		if (GUI.Button (new Rect (280, 100, 100, 30), "1986")) //Wrong answer  
		{
			Destroy (this.gameObject);
			Application.LoadLevel(Application.loadedLevel);
		}

		if (GUI.Button (new Rect (20, 150, 100, 30), "1996")) // wrong answer
		{
			Destroy (this.gameObject);
			Application.LoadLevel(Application.loadedLevel);
		}

		if (GUI.Button (new Rect (280, 150, 100, 30), "1966")) // wrong answer
		{
			Destroy (this.gameObject);
			Application.LoadLevel(Application.loadedLevel);
		}
	}

	void SetCountText()
		{
			countText.text = "Score: " + count.ToString ();
		}
}

Player collides with cube and question box appears below :slight_smile:

I would like a timer to appear when this question box is on screen and counts down from 10 to 0, with 0 destroying the questionbox and making the player restart the game. :slight_smile:

You can use something like this:

using UnityEngine;
using System.Collections;

public class timer : MonoBehaviour {
	private bool showTimer = false; //make it true when you want to display the timer
	private float time = 10f;
	private string timerText;
	
	void Update() {
		if(showTimer) {
			time -= Time.deltaTime;

			if(time < 0) {
				time = 0;
				showTimer = false;
			}
			
			var seconds = time % 60;//Use the euclidean division for the seconds.
			var fraction = (time * 100) % 100;
			
			//update the label value
			timerText = string.Format ("{0:00} : {1:000}", seconds, fraction);
		}
	}
}

You can get everything that is in Update and add it in your script.
When you need to display the timer, make the showTimer variable true.
In OnGUI, if showTimer is true, make a label to display the value stored in timerText. It should display the time like this: 09:123
In update, under if(time < 0) you can distroy the object.
