We're going to need a little more context. It would be helpful to see the code that actually enables the countdownTimer object from clicking the spawner.

 

You need to call update.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. public class Timer : MonoBehaviour
4. {
5.     public GameObject GameOverMenu, PauseButton, TimerText;
6.     public Text timerUI;
7.     public int countDownStartValue = 30;
8.     public bool isCounting;
9.  
10.     void Start ()
11.     {
12.         isCounting = false;
13.     }
14.     void Update()
15.     {
16.         If(isCounting)
17.          {
18.  
19.           countDownStartValue -= Time.deltaTime;
20.           }
21.  
22.            if(countDownStartValue < 0)
23.            {
24.             isCounting = false;
25.             }
26.     }
27.      
28. }
29.
