Start countDownTimer (displayed on UI Text) when touching a button in VR ,Starting a countDown Timer when touching a button in VR

Hey everybody,

I am quite new to Unity and I am currently working on my first project. I am doing a VR project using the HTC Vive. In this project I have a Button and when I touch it with the Controller in my game I want that object to appear and at the same time I want a countDown Timer to start. It is working that the Object appears and the countdown Timer as a separate component is working as well but the timer is already starting when I press play and I only want it to start when the button is touched. For the timer I created a Canvas and an UI Text and this UIText holds the functionality of the countDownTimer.

The Button has a script showObject that holds the functionality of making the object appear and is using a OnTriggerEnter method.

How can I now do it that I call the countDowntimer script within the showObject script? Or how can I combine the scripts if that's easier.

I already tried to call the countDownTimer Script with adding public countDownTimer CountDownTimerObj = null; to the showobjmct Script and then calling CountDownTimerObj.Update(); in the onTriggerEnter method in my showObject Script but that didn't work yet...

I don't know if it helps but here is also my code from my countDownTimer:

 public float timeValue = 90;
 public Text timerText;

 public void Update()
 {
         if (timeValue > 0)
         {
             timeValue -= Time.deltaTime;
         }
         {
             timeValue = 0;
         }
         DisplayTime(timeLeft);
 }

 void DisplayTime(float timeToDisplay)
 {
     if(timeToDisplay < 0)
     {
       timeToDisplay = 0;
     }

     float minutes = Mathf.FloorToInt(timeToDisplay / 60);
     float seconds = Mathf.FloorToInt(timeToDisplay % 60);

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

And this is my showObjectScript (it is doing some more things than just showing an object but that doesn't really matter for this question that's why I didn't mention it). Also I only included the OnTriggerEnterMethod otherwise it is too much I think.

 public GameObject Button;
 public GameObject Objekt1;
 public GameObject Objekt2;
 ....
 private int mynum;
 private int touched = 0;

 public bool Objekt1done;
 public bool Objekt2done;
 .....

 private List<int> usableObjects()
 {
    ....
     return ObjNums;
 }

 private GameObject PickRandomObject()
 {
         ..... // picks one object out of a switch statement and returns it 
     }
 }

 void OnTriggerEnter(Collider col)
 {
     if (touched == 0 || touched == 2) 
     {
         GameObject myObject = PickRandomObject();
         myObject.SetActive(true);
         Button.SetActive(false);
         touched += 1; 
         StartCoroutine(WaitThenDie())
     }
 }

 void ResetButton()
 {
     Button.SetActive(true);
     touched += 1;
 }


 IEnumerator WaitThenDie()
 {
     ....
     }

     ResetButton();
 }

}

I appreciate any help. Thank you so much in advance!!
