Count down timer C#

Question

I feel like there is somet$$anonymous$$ng 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 t$$anonymous$$s

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 t$$anonymous$$s:

 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(){
         w$$anonymous$$le(!stop){
             text.text = string.Format("{0:0}:{1:00}", minutes, seconds);
             yield return new WaitForSeconds(0.2f);
         }
     }
 }

Hope t$$anonymous$$s 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;
     }

   
      minutes = Mathf.FloorToInt(countdownTime / 60F);
     seconds = Mathf.FloorToInt(countdownTime - minutes * 60) -decreaseTime;


   


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

How do you check when it reaches 00:00? This is my code, but it won't work. if((minutes==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 Mathf.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;
     }
 }
