Count down timer C#

Question

I feel like there is something I'm missing but I don't know why I can't get my text in my canvas to display the time left float value. how do I fix this

CountDown.cs:

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class CountDown : MonoBehaviour
 {
     float timeLeft = 300.0f;
 
     Text text;
 
     void Awake ()
     {
         text = GetComponent<text> ();
     }
     
     void Update()
     {
         timeLeft -= Time.deltaTime;
         text.text = "time Left:" + timeLeft;
         if(timeLeft < 0)
         {
             Application.LoadLevel("gameOver");
         }
     }
 }

Hi Nocturnal,

On line 13 you are using GetComponent(); but the actual component you are trying to find is a Text (notice the capital 'T' ).

It would be much easier for you though if you set your Text text to a public variable and then use the inspector to drag the reference of your UI Text into the script.

Here is a slightly modified version of your script that you can use to get a nice rounded integer countdown from 300. Let me know if you have any questions about it!

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class CountDown : MonoBehaviour
 {
     float timeLeft = 300.0f;
     
     public Text text;
     
 
     
     void Update()
     {
         timeLeft -= Time.deltaTime;
         text.text = "Time Left:" + Mathf.Round(timeLeft);
         if(timeLeft < 0)
         {
             Application.LoadLevel("gameOver");
         }
     }
 }

I found Nocturnals timer a bit crude, so I came up with this:

 using System.Collections;
 using UnityEngine.UI;
 
 public class Countdown : MonoBehaviour {
 
     public float timeLeft = 300.0f;
     public bool stop = true;
 
     private float minutes;
     private float seconds;
     
     public Text text;
 
     public void startTimer(float from){
         stop = false;
         timeLeft = from;
         Update();
         StartCoroutine(updateCoroutine());
     }
     
     void Update() {
         if(stop) return;
         timeLeft -= Time.deltaTime;
         
         minutes = Mathf.Floor(timeLeft / 60);
         seconds = timeLeft % 60;
         if(seconds > 59) seconds = 59;
         if(minutes < 0) {
             stop = true;
             minutes = 0;
             seconds = 0;
         }
 //        fraction = (timeLeft * 100) % 100;
     }
 
     private IEnumerator updateCoroutine(){
         while(!stop){
             text.text = string.Format("{0:0}:{1:00}", minutes, seconds);
             yield return new WaitForSeconds(0.2f);
         }
     }
 }

Hope this helps as well

How about if I want to decrease it by 10 seconds after I click 4 times :) and the count of the click will back as 0. Then the whole process continue as the timer goes 0. HOpe you answer :)

Here's the code.

void Update() { countdownTime -= Time.deltaTime; if (DisplayItems.totalclicks==4) { decreaseTime += 10;

         DisplayItems.totalclicks = 0;
     }

   
      $$anonymous$$utes = $$anonymous$$athf.FloorToInt(countdownTime / 60F);
     seconds = $$anonymous$$athf.FloorToInt(countdownTime - $$anonymous$$utes * 60) -decreaseTime;


   


     string niceTime = string.Format("{0:0}:{1:00}", $$anonymous$$utes, seconds);
     text.text = niceTime;
 }

How do you check when it reaches 00:00? This is my code, but it won't work. if(($$anonymous$$utes==0) && (seconds == 0)) { stop = true; timer.gameObject.SetActive(false); }

         float totalTime = 120f; //2 minutes
 
         private void Update()
         {
             totalTime -= Time.deltaTime;
             UpdateLevelTimer(totalTime );
         }
 
         public void UpdateLevelTimer(float totalSeconds)
         {
             int minutes = Mathf.FloorToInt(totalSeconds / 60f);
             int seconds = Mathf.RoundToInt(totalSeconds % 60f);
 
             string formatedSeconds = seconds.ToString();
 
             if (seconds == 60)
             {
                 seconds = 0;
                 minutes += 1;
             }
 
             timer.text = minutes.ToString("00") + ":" + seconds.ToString("00");
         }

Necropost and wrong on many levels :

You can't modulo a float
If you use a modulo correctly your whole if(seconds == 60) block is useless
You don't use your formatedSeconds
No reference to timer
with your $$anonymous$$athf.RoundToInt your actual totalTime will hit zero 0.5s after your text did, what ?!?

And that's not even the worst part : You've been copy and pasting this clumsy code on multiple questions that where already answered.

Just dont do that, please ...

 float _countDownTimeLeft = 30.0f;
 bool _timerIsGoing;
 void Update()
 {
     UpdCountDown();
 }

 private void UpdCountDown()
 {
     if (_timerIsGoing && _countDownTimeLeft > 0)
     {
         _countDownTimeLeft -= Time.deltaTime;
     }
 }
